Clay Art Therapy for patients with depression: Efficacy on emotion regulation and
insight into treatment (postscript)
1. Introduction
1.1. World scenario of depression and treatment in the community
Depression is a major contributing factor to the global burden of disease. To measure
illness by Disability Adjusted Life Years (DALYs number of years of life lost with
number of years lived with a disability), among the ten leading causes of disability in
the world, unipolar depressive disorder was ranked third in 2004, with 4.3% of total
DALYs. However, it will become the number one disability adjusted illness in the
world by 2030, with 6.2% of total DALYs (World Health Organisation, 2008).
Depression currently affects 350 million people over the globe (World Health
Organization, 2012).
Mental health professionals worldwide have noticed the pressing need of treating
mental illness in the community that is more cost-effective than conventional
hospitalization. The King’s Fund of London suggests sustainable effort and
strength-based approach to help people with mental health problems return to work
during the rehabilitation process (McCrone, Dhanasiri, Patel, Knapp, & Lawton-Smith,
2008). One such example is that 50% among the 40,000 diagnosed schizophrenic
patients in Hong Kong, are treated primarily in the community (Hong Kong Hospital
Authority, 2011). Correspondingly, a brand new mode of mental health services the
Integrated Community Center for Mental Wellness (ICCMW) has been innovated in
recent years that provides community-based, short-term supportive services for
mental health outpatients (Hong Kong Hospital Authority, 2011). Art therapy is one
of the supplementary treatment approaches, in addition to pharmacological
1.2. Psychotherapy for treating depression
To date, selective serotonin reuptake inhibitors (SSRIs) are still the most popular type
of antidepressant, among which fluoxetine is most typically used (Bastos, Guimaraes,
& trentini, 2013; National Institute of Mental Health of the United States, 2013).
However, nonadherence to medication and the social stigma of illness (van Geffen et
al., 2007) have drawn attention to alternative treatment methods, such as
psychotherapy. It has been pointed out depression patients have higher adherence
rate to psychotherapy and show more incentive to sharing with psychotherapists
than passively receiving pharmacological treatment (Lee, Tsang, & Kwok, 2007).
The literature showed efficacy of various psychotherapy approaches, including art
therapy, in treating major depressive disorder (MDD) in the respects of alleviation of
depression signs and symptoms (Bar-Sela, Atid, Danos, Gabay, & Epelbaum, 2007;
Gussak, 2009), strengthening psychosocial functioning (Puig, Lee, Goodwin, &
Sherrard, 2006), and better control of relapses (Thase, 2009). It is evidenced
psychotherapy is able to increase serotonin 5HT-1A receptor densities (Karlsson,
2012), whereas treatment with fluoxetine did not (Karlsson, Hirvonen, Salminen, &
Hietala, 2013). Nevertheless, psychotherapy is being criticized as lacking scientific
evidence, such as randomized controlled trials, to endorse the efficacy (Ebmeier,
Donaghey, & Steele, 2006; Kimport & Robbins, 2012).
Cognitive dysfunction is often reported in Major Depression Disorder (MDD) with the
usual difficulties in concentrating, indecisiveness, and memory (Trivedi & Greer,
2014). Another common disorder closely related to MDD and cognitive dysfunction is
alexithymia. Alexithymia is characterized as a deficit in the cognitive processing of
affect. It exhibits in the difficulty to separate emotion expression from sensational
processes and articulate inner processes with conscious, verbal form to
communication (Karlsson, Naatanen, & Stenman, 2008; Kronholm, Partonen,
Salminen, Mattila, & Joukamaa, 2007). Despite the fact that antidepressants can help
improve cognitive symptoms, it does not persist effectively (Trivedi & Greer, 2014).
Long-term psychodynamic psychotherapy or combined psychotherapy with
fluoxetine for depressed patients are evidenced to be more efficacious in improving
neurocognitive functioning than fluoxetine alone (Bastos et al., 2013). Short-term or
long-term psychotherapy are also able to positively enhancing daily functioning in
working abilities (Knekt, Lindfors, Sares-Jäske, Virtala, & Härkänen, 2013).
1.3. Right-brain processes & emotion regulation
Emotion system is complicated; each of the integrated emotional states of mind
involves cortical-subcortical coordination and connection to brain arousal systems
(e.g. norepinephrine and serotonin) and a variety of bodily states (Panksepp, 2009).
The left brain is good at processing verbal, conscious, and rational information,
whereas the right brain is an important region of processing emotion, nonverbal,
holistic, processes, and spiritual elements (Larsen, Brand, Bermond, & Hijman, 2003).
The right brain is also intimately involved in the processing of bodily-based affective
information associated with various motivation states (Schore, 2003a, 2003b). It also
has close connections with the involuntary Autonomic Nervous System (ANS) and the
cardiovascular system to enable a quick responding system to environmental threats
and danger for survival (Schutz, 2005). Interestingly, a study researching women with
alexithymia have distinctly left-lateralization of brain processes when they were
emotionally provoked. In comparison, those participants without alexithymia showed
balanced activities in the two hemispheric brains (Karlsson et al., 2008).
Studies have supported that affect can be dysregulated in either hyperarousal or
hypoarousal states (Schore, 2002, 2003a, 2003b). Under the hypoarousal mode,
when an individual is exposed to a prolonged period of despair or hopelessness, the
dominant parasympathetic dorsal vagal system of the ANS will be turned on that
produces a dissociate state of reducing heartrates, blood pressure, and respiration.
An extended state of depressed mood and emotional detachment pose negative
impacts on the limbic system, influence regulatory functions of the ANS, and could
cumulate eventually in various disorders, such as depression (Schore, 2009).
1.4. Research on art and the brain
The relationship between art and the brain have been mostly neglected (Liu & Miller,
2008). Art making involves complex neurological processes, as implied in the various
art making procedures that involve both the mind and the body (Lusebrink, 1990,
2004). Visual art appreciation comprises aesthetic responses in which the regulatory
processes of emotion and self-reflection are involved (Vessel, Starr, & Rubin, 2012).
Combining the use of fMRI with behavioral analysis, two distinct patterns of neural
activities exhibited from two different subnetworks during visual art appreciation are
identified. These distinctive networks go through the frontal cortex and subcortical
regions, such as the amygdala. It is interesting that activity in these regions showed a
gradual increase in response to the most emotionally moving artworks as perceived
by the particular participants of the experiment (Vessel et al., 2012). Literature also
shows how training in art could help to retain some brain functions, when comparing
between stroke patients with art training and those who were not (Alajouanine, 1948;
Boller, 2005).
Studies on EEG documented the differences in the brain’s activities between artists
and non-artists. Results show significantly stronger long-range, delta band
synchronization between frontal and temporo-occipital electrodes in the artists
group as well as strong right hemispheric dominance in terms of synchronization
(Bhattacharya & Petsche, 2002, 2005). In artists, the higher synchrony in the
low-frequency band (delta-band) is probably owing to the participation of a higher
level and long-term visual art memory and extensive top-down processing hint at the
involvement of more complex activity in the neocortex. The results show that in
artists, functional cooperation between cortical regions during drawing from
memory was notably different from those in non-artists (Bhattacharya & Petsche,
2002, 2005).
1.5. Benefits of use of combined nonverbal-verbal form of communication in art
Clay work is a body-based psychotherapy that can be used in healing grief, depressed
mood, anger, and fear (Sherwood, 2004). As a form of clay work, Clay Art Therapy
(CAT) combines nonverbal and verbal elements in the psychotherapeutic processes.
The processes of clay-work integrates the experience and expression of
multi-sensory modalities (tactile, visual, proprioception (Elbrecht, 2013), auditory),
and kinesthetic activities in interacting with clay that range from gentle touch on clay
to intense input of physical energy (e.g. pounding, rolling, molding clay slump). The
processes of creating personally meaningful clay products require intense
participation of perceptual skills, affective expression, creating symbolically
meaningful clay works, cognitive functions (e.g. memory, decision making,
organization skills), and creative ability. These various processes can help raise the
ability to properly understand emotion and better control of emotional expression.
Through these processes, distorted thoughts and emotions can also be progressively
restored and organized into a holistic piece (Carr, 2008). Verbal expression of
emotions will eventually become easier in psychotherapeutic process that can
potentially benefit improvement of alexithymia (Nan & Ho, 2014).
Hypothetically, the complex, sequential processes of CAT can potentially activate
neural activities in various cortical-subcortical regions (Lusebrink, 2004) that can
benefit the attunement of psychophysiological processes (Carr, 2008) that helps
regulate emotion.
2. Methods
2. 1. Design
The study is a randomized controlled trial comparing Clay Art therapy (CAT) with
nondirective Visual Art control group (VA) that investigates the effects of clay art
making, guided by an art therapist, on depressed mood of MDD patients. Both
groups of participants are on medical treatment. Major assessments were at baseline
(T0), immediate postintervention (T1), and 3-weeks postintervention (T2).
Randomization to CAT group and VA group was done using computer-generated
random numbers.
Sample size was calculated to achieve a medium effect size of 0.15, at 80% power
and a significance level of 0.05 in repeated measures MANOVA under the proposed
experimental/control group, and three time-points design. Including the clinical and
demographic factors affecting intervention outcome and adjusting for a 25% attrition
rate, a total of 120 participants (60 per arm) is required.
The investigation has obtained ethical approval from the local institutional review
board and the informed consent of the participants was obtained.
2.2. Participants
Inclusion criteria: 1. Diagnosed MDD by psychiatrist, 2. Age 18 to 60, male or female,
3. Patients were on regular medical treatment, 4. The Chinese version of the
Beck-Depression-Inventory-II (BDI-II-C) was applied for screening. With reference to
the post-treatment test results from the pilot study (mean and minimum scores were
19/12 [Time 1); 18/3 [Time 2)); cut-off point for inclusion was set at 18 scores, the
upper limit of mild forms of depression (scores 14-19) (Beck, Steer, & Garbin, 1988;
Nan & Ho, 2014), 5. Participants had to be currently receiving services from an
ICCMW for depression outpatients, 6. Approximately 6-8 group members for each
group recruited on a convenience basis.
Exclusion criteria: Individuals with psychosis and/or suicidal attempts/tendencies
were excluded.
2.3. Procedure
Participants were recruited from three ICCMWs located in different areas because
one ICCMW did not have enough samples available for this study within the
investigation period. All of the participants were referred by the social workers
responsible for them. Participants were informed of the objectives, duration, content,
process of the groups, and other ethical considerations prior to signing the consent
form to join the groups and filling out the questionnaires. Upon confirmation of
reaching the inclusion scores by the BDI-II-C, participants were randomized to CAT or
VA treatment groups. The treatment started in the following week.
2.4. Interventions
Clay Art Therapy (CAT) takes the approach to divide the treatment mechanisms into
four major aspects the Kinesthetic/Sensory, Perceptual/Affective,
Cognitive/Symbolic and the Creative processes. The primary goal of utilizing these
treatment mechanisms aimed at monitoring the dysregulated affective process by
enhancing and balancing activities on the physical aspect (Kinesthetic and Sensory)
and functioning on other psychological processes (Perceptual, Affective, Cognitive,
Symbolic, and Creative) (Hinz, 2009).
The CAT group was held with six 2.5 hours weekly sessions. Apart from clay art
making, in-depth verbal group sharing on the clay-work process and clay products
was included for reflection at the end of each session. An art therapist facilitated the
clay art making processes and an activity worker of the serving ICCMW was assigned
to be the co-facilitator for the group, in assisting the art therapist in-charge with
coordination and administrative work.
The VA group was also held with six 2.5 hours weekly session. The group was
conducted by social workers. The group contents were similar to those of the
ordinary interest class provided by the serving participating agencies that included a
variety of content based on the preferences of the participants. These activities
included making handcraft work, coloring mandalas, verbal sharing, listening to
relaxation music or a combination of these activities. All VA group members were
subsequently arranged to join the CAT group after the completion of the study.
2.5. Measures
The Chinese version of the Beck-Depression-Inventory-II (BDI-II-C) was adapted from
the original BDIII and is an established and validated scale measuring levels of
depression (Beck et al., 1988; Byrne, Stewart, & Lee, 2004). The BDI-II-C has 21
questions, each answer being scored on a scale value from 0 to 3, with higher total
scores show more severe depressive symptoms.
The BodyMindSpiritWell-Being Inventory (BMSWBI) is an established, validated
and reliable scale (Ng, Yau, Chan, Chan, & Ho, 2005) and was found to have strong
correlations with other different scales that measure similar domains (S. M. Y. Ho,
Chan, & Ho, 2004). The BMSWBI includes four scales, including Physical Distress,
Daily Functioning, Affect, and Spirituality. Spirituality consists of tranquility,
resistance to disorientation, and resilience subscales. The BMSWBI has a total of 56
items, of which 30 are negative, for the measurement of holistic health. The
inventory uses a 10-point scale (0-10 point), with negative items scored in the
reverse order.
The Twelve-Item General Health Questionnaire (GHQ-12) is an established and
validated scale, measuring current mental health (Chong & Wilkinson, 1989; Pan &
Goldberg, 1990; GL Assessment, 2013; Goldberg & Huxley, 1980; Goldberg &
Williams, 1988). GHQ-12 measures two areas the inability to carry out normal
functions and the appearance of new and distressing experiences. Each item has 4
intervals from which to choose an answer.
The Twenty Item Toronto Alexithymia Scale Chinese (TAS-20-C) has 20 items, with
each item measured on a 5-point Likert scale within which 5 of the items are
negatively arranged. The TAS-20 consists of 3 factors: (1) DIFproblem recognizing
feelings and differentiating them from the bodily sensations of emotions (7 items); (2)
DDFproblem depicting feelings to others (5 items); and (3) EOTan externally
directed cognitive way of thinking (8 items). The TAS-20-C has shown acceptable
internal and retest reliability when applied to Chinese populations (Zhu et al., 2007).
2.6. Analysis
All analyses were conducted with Statistical Package for the Social Sciences (SPSS
version 18.0, SPSS Inc., Chicago, IL). Continuous data were presented by mean and
standard deviation (SD). Categorical data were presented by frequency (percentage).
Between-group differences at baseline were assessed by chi-squared test for
categorical data and independent t-test for continuous data.
Repeated measures MANCOVA was applied to measure the multivariate outcome of
treatment, adjusting for TAS-20 at baseline, due to a significant between-group
difference in scores. Pillai’s trace (V) was used to present the multivariate outcome
instead of Wilks’ lambda (λ), which is used only when the independent variable has
more than two groups, which was not applicable in this study. Although Wilks’
lambda is widely used, it is not as powerful as Pillai’s trace, which can be used with
any number of independent variable groups (Mayers, 2013). Univariate outcomes
were performed to assess the interaction effect of group and time for each outcome
measure. The within-group changes were assessed by paired t-test for each group.
The effect size was determined using Cohen’s d statistics. Intention-to-treat analysis
was performed in this study and missing data were substituted by the final observed
3. Results
3.1. Participants characteristics
A total of 120 were eligible for the study. After screening, 106 ((88.3%) met inclusion
criteria and agreed to participate in the study. Of these, 53 were randomized to CAT
group and 53 to the VA group. The flow of participants is shown in Figure 1.
Baseline sociodemographic and clinical variables are detailed in Table 1. The mean
age of the participants was 46.1 years (standard deviation [SD] = 10.5) in CAT group
and 44.1 years (SD = 10) in the VA group. Eighty-nine percent of the participants in
this study were female (90.4% in CAT group and 87.5% in VA group). A total of 44.2%
participants in the CAT group and 37.5% in the VA group had been diagnosed with
MDD in the previous 03 years, whereas 21.2% in the CAT group and 35.4% in the VA
group had been diagnosed with depression more than 10 years earlier. These results
reflected an interesting phenomenon, namely that the period since diagnosis did not
appear to affect the motivation of participants to join the study.
The average BDI-II-C score in the CAT group was 32.77 (SD = 9.18), defined as a
moderate form of depression according to BDI-II-C, whereas the average score in the
VA group was 28.77 (SD = 11.54), closer to the lower range of moderate depression
(29 63).
The average TAS-20 in the CAT group was 65.34 (SD = 9.21) and 59.98 (SD = 10.59) in
the VA group, with more than a total scores of 60 showing high Alexithymia. Except
in TAS-20 scores, no significant baseline differences in the three other measures were
identified between the groups and no significant differences in sociodemographic
variables between the two groups.
3.2. Efficacy
Individual scales and subscales:
As shown in Table 2, the BDI-II-C (d = -1.1), GHQ-12 (d = -0.9), and BMSWBI total
scores (d = 0.6) significantly improved in the CAT group immediately after treatment
(T1) (all p values < .001), and the improvements were all maintained at T2 (all p
values < 0.001). In the VA group, the changes in the BDI-II-C (d = -0.3), GHQ-12 (d =
-0.3), and BMSWB total scores (d = 0.3) were nonsignificant immediately at T1 and T2
(all p values > 0.05). Although the scores changed with time, the magnitude of
improvement was slight.
The TAS-20 score (d = -0.2) did not improve significantly in the CAT group at T1 (p >
0.05), but did at T2 (d = -0.4, p < 0.01). In the VA group, the change in the TAS-20
score (d = -0.1) was nonsignificant immediately at T1 and T2 (all p values > 0.05).
Although the score changed with time, the magnitude of improvement was slight
and inconsistent.
The scores of the BMSWBI subscales of the CAT group had significant improvement
immediately at T1, with Daily Functioning (d = 0.5, p < 0.001), Positive Affect (d = 0.7,
p < 0.001), Negative Affect (d = -0.6, p < 0.001), Spirit scale of Tranquility (d = 0.5, p <
0.001), and Spirit scale of Disorientation (d = -0.5, p < 0.01), and the improvements
were maintained at T2 (all p values < .001). Although Physical Distress (d = -0.1) and
Spirit scale of Resilience (d = 0.3) did not significantly improve at T1, significant
change was demonstrated at T2 (d = -0.3, p < 0.05; d = 0.5, p < 0.01, respectively).
The magnitudes of improvement of all BMSWBI subscales ranged from moderate to
strong and were generally constant.
In the VA group, only Positive Affect (d = 0.4, p < 0.05) and Negative Affect (d = - 0.4,
p < 0.05) significantly improved at T1, and only Positive Affect was maintained at T2
(d = 0.3, p < 0.05). The Spirit scale of Disorientation change was nonsignificant at T1
(d = -0.3, p > 0.05) but was significant at T2 (d = -0.5, p < 0.05). The scores of the
other BMSWBI subscales did not significantly improve at T1 or T2 (p > 0.05).
Multivariate effect of treatment:
Repeated measures MANCOVA analyses confirmed significant multivariate effects for
treatment, in interaction between group x time [v = 0.266, F (4, 94) = 3.4, p = .000,
partial η2 = 0.27]. The power to detect the effect was 0.989 (Table 3). The results
confirmed the impacts of CAT treatment. Given the significance of the overall test
result, univariate analyses were examined. The results revealed a significant effect for
interaction between group x time for BDI [F(1.8, 658.8) = 11.0, p = 0.000, η2 = 0.102],
GHQ-12 [F(1.9, 281) = 8.0, p = 0.001, η2 = 0.076], and BMS_WHOLE [F(2.0, 10472) =
4.4, p = 0.014, η2 = 0.043], but not on interaction between group x time for TAS-20
[F(1.9, 65.0) = 1.7, p = 0.185, η2 = 0.017]. The mean variance between groups in each
time point is plotted in Figure 2 that showed significant change over time.
Correlation analysis between depression signs & other aspects of change:
The correlations of depression signs, as indicated by BDI-II-C, with the other aspects
of change are shown in Table 4. At baseline, BDI-II-C was positively correlated with
GHQ-12 (R = 0.578, p < 0.01), and negatively corrected with BMS_WHOLE (R = -0.670,
p < 0.01) and TAS-20 (R = -0.298, p < 0.05). BDI-II-C was positively correlated with the
BMSBWI subscales of BMS_A (physical distress) (R = 0.496, p < 0.01), BMS_NeA
(negative affect) (R = 0.672, p < 0.01), and BMS_D_Dis (spirit_disorientation) (R =
0.346, p < 0.01); and BDI-II-C was negatively correlated with BMS_B (daily
functioning) (R = -0.400, p < 0.01), BMS_PoA (positive affect) (R = -0.407, p <0.01),
and BMS_D_Tr (spirit_tranquility) (R = -0.342, p < 0.05), but it was not correlated
with BMS_D_Res (spirit_resilience) (R = -0.070, p > 0.05).
The change in BDI-II-C at T1 was positively correlated with the changes in GHQ-12 (R
= 0.736, p < 0.01) and TAS-20 (R = 0.347, p < 0.05), and negatively correlated with
BMS_WHOLE (R = -.788, p < 0.01). The correlations were maintained in the changes
from T0 to T1 and T0 to T2. The correlation strength of BDI-II-C was strong with
GHQ-12 and BMS_WHOLE, and moderate with TAS-20.
The correlations of BDI-II-C with the BMSWBI subscales show that the change in
BDI-II-C (T1) was positively correlated with the changes in BMS_A (R = 0.555, p <
0.01), BMS_NeA (R = 0.681, p < 0.01), and BMS_D_Dis (R = 0.673, p < 0.01) and
negatively correlated with BMS_B (R = -.507, p < 0.01), BMS_PoA (R = -.695), and
BMS_D_Tr (R = -.460, p < 0.01). The correlations were maintained in the changes
from T0 to T1 and from T0 to T2. The correlation of BDI-II-C with BMS_D_Res was
nonsignificant from T0 to T1 (R = -.242, p > .05) but was significant from T0 to T2 (R =
-.323, p < 0.05). Generally, the strength of correlation of BDI-II-C with the BMSWBI
subscales ranged from moderate to strong.
4. Discussion
4.1. Significance of the study
This study aimed at investigating the combined nonverbalverbal form of Clay Art
Therapy as complementary treatment for depression outpatients in the community
setting. The findings support that CAT was more effective than nondirective visual art
control group in the benefits of reducing the level of depression and improving daily
functioning, general mental health, and holistic bodymindspirit well-being.
The positive results demonstrated that short-term therapeutic clay work treatment
guided by art therapy can supplement pharmacological treatment, not only in
symptoms reduction, but also in positively strengthening daily functioning (Choi &
Park, 2012) and enhancing personal strength, intra-personal and inter-personal
connections (Sholt & Gavron, 2006). The results supported that short-term
psychotherapy can reduce psychiatric symptoms and enhance functional abilities
(Knekt et al., 2013). The use of creative arts may have also given mental health
outpatients a positive way to face the challenges in the social environment (Sato &
Yeh, 2013) and tackle their associated disabilities (Vázquez, Holtzman, Tondo, &
Baldessarini, 2015) with cost effective and strength-based treatment method.
4.2. Speculation in the improvement of cognitive ability to process affect
In an experiment comparing women with and without alexithymia (Karlsson et al.,
2008), the mean score of TAS-20 for those 10 women with alexithymia was 62.4 (SD =
1.58), with the mean age = 35.2 (SD = 5.51), that was close to the TAS-20 baseline
scores of this study: CAT group 65.34 (SD = 1.27) and VA group 59.98 (SD = 1.53).
Despite TAS-20 scores did not show significant improvement immediately after CAT
intervention, the measurement of TAS-20 was significant as assessed three weeks
after intervention. It gave hints to the trend of the improvement of cognitive function
or cognitive ability to process affect (Karlsson et al., 2008), which the VA control
group did not exhibit such change (Figure 2) although the VA control group was
under regular pharmacological treatment during the study period. 49 out of 52 CAT
group members could complete 6 sessions, with total attendance rate = 94%.
4.3. Limitations
Although this study demonstrated the benefits of CAT among patients with
depression, the participants were all adults and most were women. The mean age of
the participants were 46.1 years (SD = 10.5) in the CAT group and 44.1 years (SD = 10)
in the VA control group respectively, in which 89% of the participants in the study
were female. The age group and gender bias may limit the power of this research
project and affect the generalizability of the study findings. This study proposes that
CAT be adopted as an intervention protocol with other age or population groups.
Another limitation that may create research bias lies in the design of the control
group. The use of nondirective art mixed media as control and led by a social worker
may arouse speculation from the participants that the real art therapy treatment was
in the CAT group and created Hawthorne effect and affect the research results. It
might be technically difficult and short of resources to locate another creative arts
therapist, such as, a music therapist, and compared the effects of CAT intervention
with music therapy. However, it is considerable to have a ceramicist to lead a clay
work control group, in comparing therapeutic and nontherapeutic use of clay work.
The selection of depression outpatients was a response to test the possibility to treat
mental illness in community setting. However, the setting of ICCMW poses potential
difficulty to effective data collection owing to the mobility of outpatients in
supportive community service setting, namely, ICCMW. With 44.2% of the CAT group
participants and 37.5% of the VA group participants being diagnosed with depression
for a duration of 0-3 years, it gave a hint that these newly diagnosed depression
patients might only receive short term supportive services in the community setting.
Once the symptoms of depression was stabilized, they would be discharged from the
ICCMW. The usual practice of posttreatment data collection was treatment sessions x
2, meaning 12 weeks after completion of CAT treatment in this study. However, 12
weeks postintervention (T2) data collection might not be feasible in the ICCMW
Another limitation was the dosage of treatment. As shown from the quantitative
results, alleviation of depressive signs in the BDI-II-C was 20.4 (T1) and 19.3 (T2). The
results showed that depressive signs were alleviated to the minimal form of
depression. It was speculated that longer treatment duration might benefit more
profound reduction of depressive signs and even possible improvement in cognitive
function of articulating affect in TAS-20 measurement. Future research direction will
be testing whether longer treatment duration (e.g. three months, six months or a
year) will be able to create optimal treatment effects of CAT. It is also recommended
to apply use of clay in different setting and investigate how clay work could be
related to possible reduction of suicidal tendency, improvement of quality of life, and
functioning in various aspects of life.
Despite the fact that clay work has been documented as a distinct therapeutic
medium (Sholt & Gavron, 2006), Clay is not a typical art medium; clay work requires
a specific set of techniques that differ intrinsically from those used in 2D art forms
such as drawing and painting. The firing of clay works also requires special
equipment, in particular a kiln. Installing and using a kiln in an art studio necessitates
special and frequent maintenance. The technical problems are not unresolvable;
however, promoting ceramic art in art education and art therapy training and
education programs is necessary. Furthermore, researchers must investigate the
therapeutic effects of a complete procedure of pottery art making in clinical
treatment, instead of testing effects of clay by interacting with it for a few minutes.
Art therapy educators must train art therapists who also are competent potters. By
doing so, the healing power of CAT can be utilized throughout the art therapy
4.4. Future research direction: Biomarkers for tracking physiological change
The somatosensory processes of involving hands in clay work take a bottom-up mode
of information processing (Society for Neuroscience, 2005) and are rich in haptic
perception (Elbrecht & Antcliff, 2014). The visual processes of guiding aesthetic
judgment and art making processes involve complex coordination of different cortical
regions (Liu & Miller, 2008) that take a top-down processing mode (Society for
Neuroscience, 2005). The experience, re-shaping and expression of emotion in group
sharing as well as in art making functions similarly to the process of emotional
learning in verbal form of psychotherapy (Bastos et al., 2013; Karlsson, 2012).
However, art making also involves autonomic nervous activities, hormonal responses,
and complex connecting work between the amygdala and the prefrontal cortex (PFC)
(Fuster, 2003) to process working memory, positive and negative emotional
expressions, and to execute decision making and the various work tasks of CAT (Carr,
2008; Davidson, Putnam, & Larson, 2000; Society for Neuroscience, 2005). The
various clay art making processes can coherently work together to aid regulating
affect and create psychophysiological attunement (Hinz, 2009) that enhances the
regulatory functions of the ANS (Schore, 2009).
For CAT involves both the mind and the body to intervention, assessing the impact by
more precisely measuring both psychological and physiological change in the future
research is essential. It is also one of the major limitations of this study that the
research results are self-reported measures. To measure physiological change, a
commonly measured biomarker for tracking the ANS is heart rate variability (HRV),
with lower HRV indicative of reduced parasympathetic cardiac control that has been
associated with disorders, such as sleep problems and difficulty in regulating
emotions (Evans et al., 2013). Another most often measured biomarker is cortisol, a
hormone indicative of change of stress response. Cortisol has been found effectively
changed in cancer patients who received Dance/Movement Therapy (R. T. H. Ho &
Fong, 2013) although it is scarcely used to measure effect of art therapy, to the
knowledge of the authors.
Another biomarker is the measurement of electroencephalography (EEG), or
specifically, event-related potential (ERP). The theoretical underpinning of this
research study, posits that creative art-making activities involve various complex
neurological processes. However, without actual neural activity measurements
obtained using neuroimaging techniques, this relationship between art making and
neurological processes can only be speculated about. The hypothesis behind using
ERP is that the impact of CAT on emotional and cognitive functioning should exert
corresponding changes in neurological processes. EEG can track change in brainwave
patterns in various brain regions and signals synchronization across various cortical
areas. The measurement in the changes in EEG signaling patterns can potentially
provide evidence to support the efficacy of CAT in alleviating emotional disturbance
or improving cognitive functioning such as concentration ability (Bhattacharya &
Petsche, 2002, 2005). (mention about pilot study prelim result?)

... Since holistic approaches to health care have gained more attention than in the past, there is a need for complementary or nonpharmacological approaches to better manage patients' health or symptoms. 15,16,32,41 Moreover, some have argued that current pharmacological approaches can be used in combination with art making to reduce negative consequences (eg, drug interaction and side effects), 30,31,42,43 or enhance health benefits from pharmacological approaches. 4,7,18,31,44 ...

These intrinsic factors include the desire to overcome or move beyond one's comfort zone, or having trust in art making. 43,46 Other intrinsic factors include participants' desire for different level of independence (eg, own pace or degree of involvement) and their positive attitudes toward art making. 15,23,47 ...
Art making has been adopted across multiple disciplines as a health intervention. However, our understanding of art making as a health intervention and how it differs from art therapy is still limited. Therefore, we conducted a concept analysis to better understand art making as a health intervention guided by Walker and Avant's approach. We examined 85 studies in which we found 4 defining attributes, 4 antecedents, and physical, cognitive, emotional, and psychological consequences. We suggest several nursing research and practical implications for nurse researchers and clinicians to aid in designing and implementing art making health interventions.

... Art-making, similar to gardening, is thought to be an innate behavior of humans [17,18], and both art-making and art therapy (AT) have been shown to provide therapeutic benefits across a range of clinical settings [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Art therapy is centered on the idea that art-making is often a nonverbal form of communication of one's thoughts and feelings involving a creative process that fosters healing, personal growth, self-understanding, quality of life improvements, and transient respite from life's ongoing challenges [35]. ...

Background: There is mounting anecdotal and empirical evidence that gardening and art-making afford therapeutic benefits. Objectives: This randomly controlled pilot study tested the hypothesis that participation in group-based indoor gardening or art-making activities for one hour twice a week for four weeks would provide quantifiably different therapeutic benefits to a population of healthy women ages 26-49. Methods: A population of 42 volunteers was randomly assigned to parallel gardening or art-making treatment groups. A total of 36 participants initiated the treatment protocol and 32 (Gardening n = 15 and Art n = 17) received the interventions and completed all assessments. Treatments included eight one-hour group-based gardening or art intervention sessions. Self-report psychometric assessments were conducted for anxiety, depression symptomatology, mood disturbance, stress, satisfaction with discretionary social activities, and quality of life measures. Cardiac physiological data were also collected. Outcomes were measured at baseline, during, and post-intervention. Results: Engaging in both gardening and art-making activities resulted in apparent therapeutic improvements for self-reported total mood disturbance, depression symptomatology, and perceived stress with different effect sizes following eight one-hour treatment sessions. Gardening also resulted in improvements for indications of trait anxiety. Based on time-course evidence, dosage responses were observed for total mood disturbance, perceived stress, and depression symptomatology for both gardening and art-making. However, gardening or art-making did not have an apparent influence on heart rate or blood pressure or result in marked improvement for satisfaction with discretionary leisure activities. Conclusion: The data did not support the hypothesis of differential therapeutic benefits of gardening and art-making for healthy women. When taken together, group-based gardening or art-making can provide quantitatively measurable improvements in healthy women's psychosocial health status that imply potentially important public health benefits. Trial registration: NCT03266120.
... The Expressive Therapies Continuum was conceptualized and created in a Western society based on Western theories and values such as goal attainment (Lusebrink et al., 2013). The ETC has been described as a culturally sensitive model (Hinz, 2019) and it has been applied in its present form to research and clinical settings in Asia (Nam, 2021;Nan & Ho, 2017;Nan, Hinz, & Lusebrink, 2021). Preliminary evidence of the cultural adaptability of the ETC is its modification for use in other cultures with emphasis placed on different aspects of creativity as appropriate to each culture (e.g., Kim, Park, & Hwang, 2020;Muhammad, 2017). ...
The Expressive Therapies Continuum (ETC) originally incorporated creativity as the Creative “level.” This denotation as a separate level is a misnomer because creativity can be present at any ETC level. Also, innate distinctive characteristics of the creative process differ from those of the other three levels. The objectives of this article are to help delineate the features of the Creative “level” within the ETC, designate its name as a Creative “dimension” to avoid confusion, and to provide case illustrations to help clarify these concepts. Creative functioning within the ETC model has been described as the integrative and self-actualizing forces within the individual occurring during expressive activities. Creative functioning has been described as comprising moments of self-realization and unique self-expression associated with well-being. These moments share similarities with the concepts of Flow, everyday creativity, small-c creativity, and mini-c creativity; concepts that can further describe creative activity in art therapy.
... On the other hand, intervention on clay therapy is reported to give good results with self-esteem problems. Nan & Ho (2017) study showed that this technique increased selfesteem in adult outpatients. Their study also revealed that it had no potential effect of clay in reducing physical symptoms and improving social functioning. ...

Art therapy is the intentional therapeutic use of the fine arts. Like music, dance, poetry and theater therapy, it is assigned to artistic therapy. This article provides an overview of general and recent developments as well as the state of the art in teaching in the discipline art therapy. Furthermore, two art therapeutic forms of intervention, the body outline image method (KUM) and Photo-Art-Therapy, are introduced. The aim is to further standardize the education and further training landscapes of art therapy, not least in order to further increase patient safety. This includes, for example, conveying systematically checked interventional measures and manuals that the students learn both theoretically and in the form of self-awareness. For about 10 years now, more and more high-impact quality research studies have been carried out Further evaluation studies in this field are desirable.
This chapter addresses the characteristics of a range of art materials used within health, wellness, and educational settings. The first part explores the foundations of art media, including media understanding and rationale for media selection, as described through the lens of historical background, theoretical viewpoints, and culturally relevant practices. Contributing factors in successful media facilitation are discussed in terms of quality and variety of materials, accessibility, adaptations, and safety. The second part provides a breakdown of a range of art materials, identifying key properties such as fluidity and structure, sensory impact, symbolic potential, practical considerations, and literature supporting the use of a broad scope of materials in art facilitation and art therapy practice. Art experientials and reflection questions will help the reader explore media components and develop firsthand knowledge and skills using a variety of materials.

People with major depressive disorder continue to be marred by chronically pernicious yet preventable outcomes in the biopsychosocial aspects. With the reallocation of healthcare resources towards the fight against the coronavirus 2019 pandemic, much emphasis has been placed on existing community mental health interventions to ameliorate the disruption of mental health services. Moreover, the recent propulsion of community mental health services by the World Health Organization Mental Health Action Plan 2013–2030 ignited the need to bolster existing community interventions by providing comprehensive, responsive and integrated mental healthcare. The enhanced emphasis on mental healthcare in the community and the heightened demands of people with major depressive disorder underscores the need to explore the current state of community mental health interventions. This scoping review examined 51 primary studies published from year 2010 to 2020 using Arskey & O′Malley's five‐stage framework and provided an overview of the impact of existing community mental health interventions for people with major depressive disorder. Findings using thematic analysis have recommended the adoption of person‐centred community mental healthcare via the biopsychosocial approach for people with major depressive disorder. Enablers of community mental health interventions were driven by culturally appropriate care and augmented by technology‐driven modalities. Challenges and gaps of community mental health interventions include the perpetuation of stigma and misconception, complex demands of persons with major depressive disorder and lack of holistic and long‐term outcomes. Given the impact of major depressive disorder on the various biopsychosocial aspects, it is envisioned that our insights into the enablers and barriers of community mental health interventions will guide prospective interdisciplinary and nurse‐led interventions in holistically improving the care of persons with major depressive disorder in the community settings.

Affect regulation is important to mental health. A deficit in one’s ability to identify and express emotions (alexithymia), cognitive styles of regulating emotional conflict (defenses), and the capacity for integrative and complex self-other understanding (ego strength or maturity) need to be studied to understand how they relate to each other as well as to mental health and well-being. A sample of 415 community-dwelling adults from a major metropolitan area in the Midwest U.S., stratified for gender, age, and ethnicity, completed three methodologically different measures of affect regulation along with measures of well-being and depression. Six years later, 49 % of the sample again reported their well-being and depression. At baseline, ego strength and the defenses of principalization and reversal correlated negatively with alexithymia and the other defenses (turning against self, turning against object and projection), even after controlling for negative affect. Cross-sectionally, relationships were largely as hypothesized, with low alexithymia, use of mature defenses, and greater ego strength correlating with less depression and greater well-being, although some of these relationships were attenuated after controlling for negative affect. Prospectively, each of the affect regulation measures predicted hypothesized changes in well-being after 6 years, after controlling for baseline well-being, but affect regulation did not predict changes in depression. These findings illuminate similarities and differences among these affect regulation constructs, suggest the importance of differentiating well-being from depression, and reveal that affect regulation uniquely predicts changes in long-term well-being.

Purpose: This study aimed to evaluate the efficacy of supportive-expressive group (SEG) therapy and body-mind-spirit (BMS) intervention on emotional suppression and psychological distress in Chinese breast cancer patients. Methods: This three-arm randomized controlled trial assigned 157 non-metastatic breast cancer patients to BMS, SEG, or social support control group. SEG focused on emotional expression and group support, whereas BMS emphasized relaxation and self-care. All groups received 2-h weekly sessions for 8 weeks. The participants completed measurements on emotional suppression, perceived stress, anxiety, and depression at baseline and three follow-up assessments in 1 year. Results: Using latent growth modeling, overall group difference was found for emotional suppression (χ (2)(2) = 8.88, p = 0.012), marginally for perceived stress (χ (2)(2) = 5.70, p = 0.058), but not for anxiety and depression (χ (2)(2) = 0.19-0.94, p > 0.05). Post-hoc analyses revealed a significant and moderate reduction (Cohen d = 0.55, p = 0.007) in emotional suppression in SEG compared to control group, whereas BMS resulted in a marginally significant and moderate fall (d = 0.46, p = 0.024) in perceived stress. Neither SEG nor BMS significantly improved anxiety and depression (d < 0.20, p > 0.05). Conclusions: The present results did not demonstrate overall effectiveness for either BMS or SEG therapy in the present sample of Chinese non-metastatic breast cancer patients. The participants appear to derive only modest benefits in terms of their psychological well-being from either intervention.

Context: Integrated interventions with combined elements of body movement and psychotherapy on treatment-related symptoms in cancer patients are relatively scarce. Objectives: The present study aimed to study the effectiveness of dance movement therapy (DMT) on improving treatment-related symptoms in a randomized controlled trial. Methods: A total of 139 Chinese patients with breast cancer awaiting adjuvant radiotherapy (RT) were randomized to DMT or control group. The intervention included six 1.5-hour DMT sessions provided twice a week over the course of RT. Self-report measures on perceived stress, anxiety, depression, fatigue, pain, sleep disturbance, and quality of life were completed before and after the three-week program. Results: DMT showed significant effects on buffering the deterioration in perceived stress, pain severity, and pain interference (Cohen d = 0.34 to 0.36, P < 0.05). No significant intervention effects were found on anxiety, depression, fatigue, sleep disturbance, and quality of life (Cohen d = 0.01 to 0.20, P > 0.05). Conclusion: The short-term DMT program can counter the anticipated worsening of stress and pain in women with breast cancer during radiotherapy.
Objectives: To identify the mechanisms involved in the association between self-compassion and depression, we examined whether adaptive emotion regulation would mediate the relationship between self-compassion and depression in individuals with unipolar depression. Furthermore, we explored which specific emotion regulation skills would be most important in this relationship. Design and method: Sixty-nine individuals with unipolar depression were assessed with the Self-Compassion Scale and the Emotion Regulation Skills Questionnaire at baseline and with the Beck Depression Inventory-II 1 week later. Results: The results showed that successful application of emotion regulation skills mediates the association between self-compassion and depression. Among eight specific emotion regulation skills, only the ability to tolerate negative emotions was identified as a significant mediator in the self-compassion-depression relationship. Conclusions: These findings provide preliminary evidence that systematically fostering self-compassion might help depressed individuals cope with their symptoms by enhancing their abilities to tolerate undesired emotions. Practitioner points: Systematically fostering self-compassion through specific compassion-focused interventions might facilitate a reduction in depressive symptoms by improving the person's emotion regulation abilities, especially by improving his or her ability to tolerate negative emotions. Hence, compassion-focused interventions might be particularly promising in depressed patients with a tendency to avoid negative emotions and deficits in tolerating them.
Major Depressive Disorder (MDD) is an affective disorder with sustained negative affect and difficulties experiencing positive affect as its hallmark features. Previous work also highlights cognitive biases and deficits in cognitive control that accompany depression and suggestions have been made how cognitive and affective aspects of the disorder are linked. Recent work proposes that difficulties in the self-regulation of affect after experiencing negative life events may contribute to risk for the onset of depression and indeed there is evidence that depressed patients exhibit more frequent use of maladaptive strategies when regulating affect and show difficulties effectively implementing adaptive strategies. Cognitive aspects of depression may play an important role in helping us understand these difficulties in self-regulation. This article reviews recent work on emotion regulation in depression and links cognitive biases and deficits associated with depression to difficulties in the self-regulation of emotion. Importantly, a main goal of the article is to identify topics in need of future attention that could greatly help shed light on the relation between cognition and emotion regulation in this and other psychological disorders.
The effects of psychotherapy have traditionally been measured by change in core symptoms, psychological abilities (personality, defenses, cognitions, etc.), or social functioning. With the advent of functional brain imaging methods (such as SPECT, PET, fMRI, and MEG), it has become possible to include a new dimension in the measurements, namely changes in brain functions after psychotherapy. Several studies investigating change in cerebral blood flow or metabolism have been published, and they have showed that different forms of psychotherapy indeed lead to brain changes [1, 2]. These studies have been usually performed with patients suffering from depressive or anxiety disorders, and the treatments have in the majority of the studies been cognitive-behavioral therapy (CBT) or interpersonal psychotherapy (IPT).
Expressive Therapies Continuum is distinctive in its application as a foundational theory in the field of art therapy. First developed by Vija Lusebrink, this theory can be used by persons of any theoretical orientation, and has the ability to unite art therapists of varying backgrounds. The information contained in this book demonstrates how the Expressive Therapies Continuum provides a framework for the organization of assessment information, the formulation of treatment goals, and the planning of art therapy interventions. It provides rich clinical detail and many case examples that enliven the text and promote student engagement and learning. Hinz divides material into three parts. The first describes the historical roots of the Expressive Therapies Continuum and pays homage to contributions from the fields of art and psychology. The seven component parts of the ETC are examined in the second part, and the last part of the book is dedicated to assessment and clinical applications. This book's easy-to-use format and effectiveness in teaching history and application make it an essential reference for therapists and students.
