EMOTIONAL CLARITY, NEUROTICISM, AND MDD
2
Abstract
Investigators have begun to document links between emotional clarity and forms of negative
emotionality, including neuroticism and Major Depressive Disorder (MDD). Research to date has relied
almost exclusively on global self-reports of emotional clarity; moreover, no studies have examined
emotional clarity as a function of valence, although this may prove to be crucial in understanding the
relation of emotional clarity to maladjustment. In two studies, we used experience sampling methodology
and multi-level modeling to examine the associations between emotional clarity and two constructs that
have been linked theoretically with emotional clarity: neuroticism and depression. In Study 1 we assessed
95 college students who completed a self-report measure of neuroticism. In Study 2 we examined 53
adults diagnosed with MDD and 53 healthy adults. Reaction times to negative and positive emotion
ratings during the experience sampling protocols were used as an indirect measure of emotional clarity.
Neuroticism was related to lower clarity of negative, but not of positive, emotion. Similarly, compared to
the healthy controls, individuals with MDD had lower clarity of negative, but not of positive, emotion.
Importantly, findings from both studies held after controlling for baseline reaction times and current
levels of negative and positive emotion. These findings highlight the importance of assessing valence
when examining emotional clarity and increase our understanding of the nature of the emotional
disturbances that characterize neuroticism and MDD.

Emotional Clarity as a Function of Neuroticism and Major Depressive Disorder
Emotions provide individuals with information: They help people navigate their lives and inform
them if their goals, needs, and concerns are being met (Carver & Scheier, 1990; Lazarus, 1991; Schwarz
& Clore, 2003). In this context, being unclear about how one feels is likely to be maladaptive. For
example, how do people decide what actions to take if they are basing decisions on inaccurate
information? How well can people successfully regulate emotions about which they are confused? Dizén,
Berenbaum, and Kerns (2005) found that people who are less clear about their emotions are also less
aware and less clear about their psychological needs.
Emotional clarity refers to the extent to which individuals can unambiguously identify, label, and
mentally represent the type (e.g., sadness, nervousness) and source or cause of emotions they feel
(Coffey, Berenbaum, & Kerns, 2003; Gohm & Clore, 2000). The extent to which people are clear about
their emotional experiences varies continuously and is an individual difference construct (Gohm & Clore,
2000). Lower levels of emotional clarity have been associated with poorer emotion regulation (e.g., Gratz
& Roemer, 2008; Salovey, Mayer, Goldman, Turvey, & Palfai, 1995; Tull, Barrett, McMillan, & Roemer,
2007) and diminished psychological well-being (e.g., Saxena & Mehrotra, 2010; Augusto-Landa, Pulido-
Martos, & Lopez-Zafra, 2011; Landa, Martos, & Lopez-Zafra, 2010; Montes-Berges & Augusto-Landa,
2014; Saxena, Dubey, & Pandey, 2011). For example, individuals who are diagnosed with Major
Depressive Disorder (MDD) report lower levels of emotional clarity than do non-psychiatric controls
(Loas et al., 1998). Similarly, college students whose depressive episodes are in remission report lower
levels of emotional clarity than do their never depressed peers (Ehring, Fischer, Schnulle, Bosterling, &
Tuschen-Caffier, 2008).
The study of emotional clarity has been extended to the domain of personality. In particular,
researchers have examined relations between emotional clarity and global or trait measures of
neuroticism, or trait negative affect. Neuroticism has been consistently associated with lower levels of
emotional clarity in samples of college students (Coffey et al., 2003; Euse & Haney, 1975; Extremera &
Fernandez-Berrocal, 2005; Gohm & Clore, 2002; Salovey et al., 1995).
EMOTIONAL CLARITY, NEUROTICISM, AND MDD

There are two reasons to expect both neuroticism and MDD to be inversely related to emotional
clarity. First, if depressed individuals are indeed characterized by diminished levels of emotional clarity,
risk factors for the development of MDD, particularly those that have an emotional component, may also
be associated with low levels of emotional clarity. In this context, neuroticism, which has been linked to
negative affectivity (e.g., Watson, Wiese, Vaidya, & Tellegen, 1999), is posited to serve as a risk factor
for MDD (e.g., Barlow, Sauer-Zavala, Carl, Bullis, & Ellard, 2013). Second, it is possible that
neuroticism and MDD have in common underlying processes, such as a shared genetic diathesis (e.g.,
Mineka, Watson, & Clark, 1998; Watson & Clark, 1995).
Researchers examining emotional clarity have almost exclusively used global self-report
measures, which have notable limitations. Perhaps most important, the extent to which people can
accurately introspect and report on their emotional clarity is unclear. Lischetzke, Angelova, and Eid
(2011) used a novel method to assess emotional clarity as part of an experience sampling study.
Participants rated how they were feeling in the moment, and their reaction times (RT) to make these
ratings were used as a proxy for emotional clarity. Presumably, faster ratings on emotion items reflect
greater clarity about emotions. Lischetzke and colleagues (2011) found that although these RTs were not
related to global self-reports of emotional clarity, they were related to participants’ certainty about their
feelings in the moment. Further, faster RTs, but not global measures of emotional clarity, predicted
greater subsequent self-reported mood-regulation success during the experience sampling protocol.
Indirect assessments of emotional clarity also reduce possible influences of cognitive biases that
have been found to characterize clinical populations, including individuals with MDD (e.g., memory
biases; Mathews & MacLeod, 2005). Finally, retrospective self-report measures suffer more generally
from the weakness of being far removed from the actual situations and contexts in which people actually
experience their emotions. Assessing emotional clarity in the context of people’s daily lives provides
information with greater ecological validity. Thus, in order to assess level of emotional clarity more
reliably, it is important to use methods other than retrospective self-report.
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
5
In addition to these methodological issues, investigators examining emotional clarity, including
researchers studying neuroticism and MDD, have yet to assess emotional clarity as a function of valence.
Although there is evidence that MDD and neuroticism are related to lower levels of emotional clarity, it is
unclear whether these results for emotional clarity hold for both positive and negative emotions, or
alternatively, whether diminished emotional clarity is unique to negative or positive emotions. There are
important clinical implications for understanding whether disturbances in emotional clarity are general or
are specific to one valence. For example, if difficulties in emotional clarity are specific to negative
emotions, then treatment components targeting emotions need to focus on helping clients learn how to
better identify only their negative, and not their positive, emotions.
We hypothesize that neuroticism and MDD will be characterized by decreased clarity of negative,
but not positive, emotions. Individuals vulnerable to and diagnosed with MDD exhibit a variety of
negative cognitive biases in memory, attention and the interpretation of ambiguous information (e.g.,
Alloy, Abramson, Walshaw, & Neeren, 2006; Gotlib & Joormann, 2010). For example, people with
MDD exhibit difficulty removing negative material from working memory (e.g., Levens & Gotlib, 2010).
This strong focus on negative valence may obscure the clarity about the specific negative feelings they
may experience. Indeed, people with MDD struggle in their understanding of specific negative emotions.
For example, individuals with MDD have less differentiated negative emotions than do healthy controls
(Demiralp et al., 2012); importantly, the groups do not differ on differentiation of their positive emotions.
Similarly, neuroticism is associated with lower levels of differentiated negative emotions (Erbas,
Ceulemans, Pe, Koval, & Kuppers, 2014).
In addition, there are also two lines of research that provide at least indirect support for our
central hypothesis that neuroticism and MDD will be associated with reductions in the clarity of negative,
but not positive, emotions. First, both neuroticism (Nolen-Hoeksema, Wisco, & Lyubomirsky, 2008) and
MDD (Aldao, Nolen-Hoeksema, & Schweizer, 2010) have been found to be associated with poor
regulation of negative emotions. We posit that these problems with emotion regulation are due in part to
these individuals being unclear about their negative emotions. In other words, we think that the
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
6
diminished clarity of negative emotion is one factor that leads to subsequent difficulties in regulating
negative emotions. Consistent with this formulation, investigators have shown that participants with
lower clarity of emotion have greater difficulty repairing experimentally induced negative moods
(Salovey et al., 1995).
Although we conceptualize emotional clarity as being central to understanding why people
experience aberrations in negative emotions, emotional clarity may play less of a key role in
understanding the relations between positive emotions and neuroticism or MDD. First, neuroticism is
generally unrelated to positive emotions; even though MDD is associated with diminished positive
emotions, the particular issue is that people do not experience enough positive emotion (Watson, Clark, &
Carey, 1988). We think that the main issues involved in understanding aberrations in positive emotions
related to neuroticism and MDD will be linked to factors and processes that clarify the elicitation,
maintenance, and up-regulation of positive emotions, and emotional clarity may not be central to these
processes. Indeed, in a related line of research, Barrett, Gross, Christensen, and Benvenuto (2001) found
that emotion regulation was related to the extent to which people differentiated negative, but not positive,
emotions.
The second line of research that provides indirect support for our central hypothesis involves the
construct of emotional instability. Higher levels of emotional variability have been found to be associated
with less emotional clarity (Thompson, Berenbaum, & Bredemeier, 2011). In this context, compared with
healthy controls, individuals diagnosed with MDD experience greater variability of negative, but not of
positive, emotions (e.g., Houben, Van den Noortgate, & Kuppens, in press; Peeters, Berkhof, Delespaul,
Rottenberg, & Nicolson, 2006; Thompson et al., 2012). Thus, we predict that depressed individuals will
experience lower clarity of negative, but not of positive, emotions.
Before examining the specific mechanisms that may underlie possible lower levels of clarity of
negative emotions in individuals with high levels of neuroticism or MDD, it is important that we elucidate
the relations between emotional clarity and both neuroticism and MDD. Therefore, in the first study,
which involves the reanalysis of existing data (e.g., Kuppens, Allen, & Sheeber, 2010), we examined the
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
7
strength of the relation between emotional clarity and trait neuroticism in a sample composed largely of
college students. In the second study, we examined the relation between emotional clarity and MDD in a
community sample of adults who were in a current depressive episode or who had no history of any
mental health disorders. Importantly, in both studies participants completed experience-sampling
protocols that included items assessing their current levels of positive and negative emotion. This allowed
us to measure negative and positive emotional clarity using participants’ RTs to endorse negative and
positive emotions, respectively. This is the first study to use RTs to examine clarity of positive and
negative emotions as a function of neuroticism and MDD.
Method
Participants and Procedure
Study 1: An initial sample of 80 participants took part in the study, of which 77 were university
students and 3 were university personnel.1 They were recruited by responding to ads that were placed
around the university campus. One participant withdrew after the first day of data collection, resulting in a
final sample of 79 participants (63% female). They ranged in age from 18 to 67 years (M = 24; SD =
7.82). All participants had Belgian nationality and are from European ethnicity. Participants came from a
variety of disciplines, including, the humanities (42%), science and technology (22%), and biomedical
sciences (22%). Participants provided informed consent and were compensated for their participation.
In the first session, each participant received a Tungsten E2 palmtop computer along with
instructions for how to use it to respond to the questions at each prompt. Each palmtop was programmed
to beep 10 times a day for 14 consecutive days during the participant’s waking hours using the
Experience Sampling Program 4.0 (D. J. Barrett & Feldman Barrett, 2000) on the basis of a stratified
random interval scheme (dividing each participant’s waking hours into ten equal periods and randomly
assigning one prompt in each interval). At each prompt, the palmtop presented a number of questions in
randomized order, including items about the experience of specific emotions and questions about the
circumstances that led to them. For the next two weeks, participants carried the palmtop during their
normal daily activities and responded to the questions when signaled. Compliance was good: overall,

8
participants responded to 82% of the prompts. After two weeks, participants attended a second session in
which they were debriefed and paid for participation. All participants also completed a battery of self-
report measures either before or after the sampling procedure, as determined by random assignment.
These measures included questionnaires assessing self-esteem, emotion, emotion-regulation, self-esteem
(which are not relevant to the current research question) and a personality scale (see below).
Study 2: Adults from the surrounding communities of Ann Arbor, Michigan, and Stanford,
California, were recruited using postings at local businesses and online (e.g., Craigslist). To be eligible for
participation, people needed to be between 18 and 40 years old (M = 26.8, SD = 6.5) and be native
English speakers. The sample was largely women (69.8%) and ethnically/racially diverse: 67.9% white,
7.5% African American, 10.4% Asian American, 2.8% Latino/a, 9.4% multi-racial and 1.9% indicated
“other.” Participants were highly educated with approximately 51.9% having a bachelor’s degree or
higher. People were required to either have no history of any mental health disorder (CTL; n = 53) or be
in a current depressive episode (MDD; n = 53). Mental health status was assessed using the Structured
Clinical Interview for DSM-IV (SCID-I; First, Spitzer, Gibbon, & Williams, 2001). Additional eligibility
requirements for the control group included a Beck Depression Inventory–II (BDI-II; Beck, Steer, &
Brown, 1996) score of 9 or less. Additional eligibility for the depressed group included a BDI-II score of
14 or higher, and no alcohol/drug dependence in past six months, Bipolar I or II diagnoses, or psychotic
disorders. The final sample of 106 participants excluded 15 participants because of equipment failure (n =
12; 7 CTLs, 5 MDDs) or noncompliance (n = 3; all MDDs). The MDD and control groups did not differ
significantly in gender (2(1) = 0.18, p = .83), race–ethnic composition (2(5) = 7.79, p = .17), or
educational attainment (2(3) = 6.67, p = .08). Individuals with MDD, however, were significantly older
than control participants (t(104) = 2.19, p < .05).2
At their first session, participants completed the lifetime SCID, which was administered by
graduate and post-baccalaureate students who had received extensive training. Diagnostic reliability was
assessed by randomly selecting and re-rating recorded interviews. Our team has achieved excellent inter-

9
rater reliability for a major depressive episode (k = .93) and for classifying participants as non-psychiatric
controls (k = .92; Levens & Gotlib, 2010). Participants returned to the laboratory for a second session to
complete a series of self-report measures, including the one described below. At this session, they were
instructed on the experience sampling method (ESM) protocol, including completing a full practice trial.
Participants carried a hand-held electronic device (Palm Pilot Z22) that was programmed using
the Experience Sampling Program 4.0 (D. J. Barrett & Feldman Barrett, 2000). They were prompted (via
a tone signal) eight times per day between 10 a.m. and 10 p.m. The majority of participants carried the
device for 7 to 8 days to be prompted 56 times. Prompts occurred at random times within eight 90-min
windows per day; thus, prompts could occur between 2 and almost 180 min apart (M = 93 min, SD = 38
min). After a prompt, participants had 3 min to respond to the initial question. For each ESM item, an RT
was recorded. MDD and CTL groups did not differ in the percentage of completed prompts (MDD =
77.9%, CTL = 81.0%, t(104) = 1.24, p = .22). Participants provided informed consent and were
compensated for their participation, with an extra incentive for responding to more than 90% of the
prompts. The protocol was approved by the Institutional Review Boards of University of Michigan and
Stanford University.
Neuroticism. In Study 1, the Dutch translation of the NEO-Five Factor Inventory (FFI)
personality questionnaire (Hoekstra, Ormel, & de Fruyt, 1996) was used to measure neuroticism. The
questionnaire consists of 60 items, with 12 items measuring each of the Big Five personality dimensions.
Respondents are asked to indicate the degree to which they agree or disagree with each of the statements
using a five-point Likert-type scale (ranging from 0 = strongly disagree, 4 = strongly agree; Cronbach
= .88).
Emotion ratings. Finally, to rule out the possibility that people take longer to respond to emotion
items that they endorse strongly, we controlled for within-person mean levels of current emotion. At each
prompt, participants reported their current levels of negative and positive emotions. Each study
administered a different list of emotion words. To maximize comparison of results from each study, we
limited the analyses to emotions that were administered in both studies. For negative emotion, we used
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
10
ratings for angry, sad, and anxious. For positive emotion, we used ratings for happy and excited.3 In Study
1, participants indicated the extent to which they were currently feeling each emotion using a continuous
slider scale that ranged from 0 (not at all) to 100 (very much). For Study 2, participants used a 4-point
scale (1 = not at all, 4 = a great deal) to report the extent to which they were currently feeling each
emotion at each prompt. We calculated the between and within-person reliability values for negative and
positive emotions using MIXED methods (see Shrout & Lane, 2011, for detailed information, including
syntax). For Study 1 for negative emotion, the between-person reliability was .995 and the within-person
reliability was .657, and for positive emotion the between-person reliability was .994 and the within-
person reliability was .715. For Study 2 for negative emotion, the between-person reliability was .994 and
the within-person reliability was .570, and for positive emotion the between-person reliability was .997
and the within-person reliability was .751. Across studies, the between-person reliabilities were excellent
and the within-person reliability values are in the moderate range (Shrout, 1998).
Emotional clarity. As described above, based on previous work (e.g., Lischetzke et al., 2011),
we operationalized emotional clarity as the speed with which participants responded to emotion items
during the experience-sampling period. Because of the non-normal distribution of the data in our analyses
and to avoid excessive influence of outliers (which occur given the nature of collecting experience
sampling data), RTs were log transformed before computing averages or conducting analyses. For clarity
of negative and positive emotions, mean scores for the log-transformed RTs to negative and positive
emotion items, respectively, were calculated at the prompt-level (i.e., for each participant for each
prompt). Study 2 also assessed global emotional clarity. Participants were administered the emotional
clarity subscale of the Trait Meta Mood Scale (TMMS; Salovey et al., 1995).
Baseline reaction time. We included baseline RTs as a covariate in our analyses at the within-
person level. 4 It is important to control for baseline RTs when examining RTs to valenced stimuli.
However, it was particularly important to do so for Study 2 because some people with MDD exhibit
psychomotor retardation (American Psychiatric Association, 2013). To assess baseline RT, log-
transformed RTs across all non-emotion items were averaged for each prompt to provide a general RT
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
11
variable. RTs to any item that included an emotion term were excluded. More specifically, for Study 1,
this included items asking participants to provide information about their ongoing situation and how they
appraised the situation. For Study 2, this included items assessing physical activity (Mata et al., 2012),
significant events (Thompson et al., 2012), as well as mind wandering and rumination.
Analytic overview
Because of the nested data structure (prompts nested within individuals), we tested our
hypotheses using multilevel modeling. Multilevel modeling simultaneously estimates within- and
between-person effects (Krull & MacKinnon, 2001) while handling varying time intervals between
prompts and missing data (Snijders & Bosker, 1999). Importantly, multilevel modeling does not assume
independence of data points. We used hierarchical linear modeling (HLM 6.08; Raudenbush, Bryk, &
Congdon, 2008) and report parameter estimates with robust standard errors. Full models, all of which
were random effects models (i.e., intercepts and slopes were allowed to vary), are described in each
respective section.
For both studies, we conducted a series of multilevel models. First, we examined whether
negative emotional clarity varied as a function of the Level 2 variables, neuroticism (Study 1) and
depression status (Study 2), after controlling for the Level 1 variables: mean log-transformed RT on non-
emotion items at that prompt (i.e., baseline RT), and the level of negative emotion at that prompt (all
Level-1 predictors person-mean centered). Then, we conducted the same multilevel analyses for positive
emotional clarity. For Study 1, in the equations below, i represents beeps or prompts and j represents
participants. In all models that included neuroticism as a Level 2 (between-person) variable, neuroticism
was grand-mean centered.
Level 1 Model (prompt level)5:
RT to emotion itemsij = 0j + 1j* mean emotion + 2j* baseline RT + rij 1a
Level 2 Model (person level):
0j = 00 + 01*(neuroticism) + u0j 1b
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
12
1j = 10 + 11*(neuroticism) + u1j 1c
2j = 20 + 21*(neuroticism)+ u2j 1d
For Study 2, all models were identical to those presented in Study 1, with the exception that
depression status instead of neuroticism was included as a Level 2 (between person) variable (dummy-
coded as 0 = CTL group; 1 = MDD group). The equations below represent the series of multilevel models
we conducted on the participants in Study 2.
Level 1 Model (prompt level)2:
RT to emotion itemsij = 0j + 1j* mean emotion + 2j* baseline RT + rij 2a
Level 2 Model (person level):
0j = 00 + 01*(depression status) + u0j 2b
1j = 10 + 11*(depression status) + u1j 2c
2j = 20 + 21*(depression status)+ u2j 2d
Results
Study 1
In Table 1, we present the average scores and within- and between-person standard deviations for
RT to negative and positive emotion items as well as levels of negative and positive emotion. Next, we
examined the correlations between RTs to negative versus positive emotion items at the within-person
level (Nezlek, 2012) and at the between person level, using aggregated values across the ESM period. At
the within-person level correlation, RT to negative emotion items was moderately correlated with RT to
positive emotion items, r = .47, p < .001. At the between-person level, they were correlated at r = .63, p <
.001; when controlling for baseline RT, RT to negative emotion items was moderately correlated with RT
to positive emotion items, r = .48, p < .001. These correlations suggest that clarity of negative and
positive emotions (i.e., RT to negative and positive emotion items) overlap but are not redundant.
Negative emotional clarity. The top half of Table 2 presents results from the negative emotional
clarity model (see Figure 1A for a graphical representation of the findings). People with higher levels of
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
13
neuroticism had longer RTs to endorse negative emotion items (see γ01). This suggests that higher levels
of neuroticism were related to lower levels of negative emotional clarity. Importantly, the model
controlled for the level of current negative emotion and participants’ current baseline RT. Findings also
show that RTs increased with the level of reported negative emotion (see γ10); further, this relation was
moderated by levels of neuroticism (see γ11). Although on average it took participants longer to report
negative emotions as their levels of negative emotions increase, this effect was weaker for participants
with high levels of neuroticism. Baseline RT was positively related to RT to negative emotion items (see
γ20), but this relation was not moderated by levels of neuroticism (see γ21).
Positive emotional clarity. The bottom half of Table 2 presents results from the positive
emotional clarity model (see Figure 1A). After controlling for average level of current positive emotion
and participants’ current baseline RT, neuroticism was not significantly related to participants’ RT to
positive emotion items (see γ01). Thus, positive emotional clarity was not related to levels of neuroticism.
In addition, RTs increased with higher levels of reported positive emotions (see γ10), but this relation did
not vary as a function of neuroticism (see γ11). Baseline RT was also positively related to RT to positive
emotion items (see γ20), but the relation between baseline RT and RT to positive emotion items did not
vary as a function of levels of neuroticism (see γ21).
Study 2
Next, we examined our hypotheses in an adult community sample, half of whom were in a major
depressive episode (MDD group) and half of whom had no current or past history of any mental health
disorders (CTL group). See Table 1 for the average values and within- and between-person standard
deviations for RT to negative and positive emotion items as well as of negative and positive emotion as a
function of MDD status. Next, we examined the validity of using RTs to in-the-moment ESM ratings of
negative and positive emotion ratings to assess emotional clarity. Study 2 included an assessment of
emotional clarity using a global self-report measure. Controlling for baseline RT, scores on the global
emotional clarity scale were not significantly associated with aggregated RTs to negative emotion items
(MDD: r = .15, p = .31; CTL: r = .05, p = .75) or with aggregated RTs to positive emotion items for the
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
14
MDD group (r = -0.12, p = .42). On the other hand, global emotional clarity was significantly associated
with RTs to positive emotion items for the CTL group, controlling for baseline RT (r = .29, p = .04). As
in Study 1, we examined the correlation coefficients between RT to negative and positive emotion items
at the within- and between-person level. At the within-person level, RTs to negative and positive emotion
items were weakly associated, r = .14. At the between-person level, however, they were strongly
correlated, r = .77, p < .001; when controlling for baseline RT, RTs to negative and positive emotion
items were moderately related, r = .55, p < .001. As in Study 1, these correlations suggest that RTs to
negative and positive emotion items are not redundant.
Negative emotional clarity. The top half of Table 3 presents results from the negative emotional
clarity model (see Figure 1B for a graphical representation of the findings). Compared to the healthy
control group, the MDD group had longer RTs to negative emotion items (see MDD (γ01) row for the
intercept (β0)). Thus, the MDD group had lower levels of negative emotional clarity than did the CTL
group. Importantly, the model controlled for average level of negative emotion and participants’ baseline
RTs to non-emotion items at each prompt. In addition, RTs increased (i.e., emotional clarity decreased) as
the level of reported negative emotions increased for the CTL group (see γ10). This relation, however, was
moderated by group status (see γ11): As the level of reported negative emotions increased, the MDD group
exhibited a smaller increase in RTs to negative emotion items than did the CTL group. Baseline RT was
positively related to RT to negative emotion items, and the relation between baseline RT and RT to
negative emotion items did not vary as a function of depression status (see γ20 and γ21, respectively).
Positive emotional clarity. The bottom half of Table 3 presents results from the positive
emotional clarity model (see Figure 1B for a graphical representation of the findings). After controlling
for the level of positive emotion and participants’ baseline RT to non-emotion items at each prompt, the
MDD group did not demonstrate significantly higher RTs to positive emotion items (see γ01) than did the
CTL group (γ00). In other words, there was no moderation based on MDD status. Higher levels of positive
emotion were related to higher RTs for the CTL group (γ10), this relation was not moderated by group
status (γ11). In other words, higher levels of positive emotion were related to longer RTs for all

participants independent of their depression status. Finally, baseline RT was also positively related to RT
to positive emotion items (γ20), but this relation was also not moderated by group status (γ21).
Discussion
We hypothesized that neuroticism and MDD are characterized by a similar emotional deficit—
experiencing lower clarity of negative but not of positive emotions. We posited that individuals with
higher neuroticism and MDD have deficits in their knowledge of negative emotions. This theorizing is
consistent with research on a conceptually related but distinct construct (Boden, Thompson, Dizen,
Berenbaum, & Baker, 2012) of emotional differentiation. Less differentiation of negative emotions is
related to higher neuroticism (Erbas et al., 2014) and characterizes people with MDD compared to healthy
controls (Demiralp et al., 2012).
We were able to test our hypothesis in two studies examining emotional clarity in people’s day-
to-day lives in terms of how quickly they respond to items assessing their momentary experience. We
found that participants’ longer RTs to make ratings of their negative, but not positive, feelings in-the-
moment were related both to higher levels of neuroticism (Study 1) and to a diagnosis of MDD (Study 2).
Given that slower responses to emotion items reflect lower emotional clarity, our results suggest that
individuals high in neuroticism or with MDD are less clear about their negative emotions in daily life.
This lower clarity may have important intrapersonal and interpersonal consequences. Intra-personally, for
example, it may give individuals less accurate information about how a specific event impinges on their
concerns (Dizen et al., 2005), and how they can deal emotionally with the event (Butler & Randall, 2013).
Interpersonally, diminished emotional clarity may hinder adequate emotion regulation or social support
(Butler, 2011).
In contrast to negative emotional clarity, positive emotional clarity did not vary as a function of
participants’ levels of neuroticism (Study 1) or depression status (Study 2). These findings are important
because past research examining relations between emotional clarity and both neuroticism and MDD has
conceptualized emotional clarity as a general disturbance in emotion, rather than a disruption that may
vary by valence. The present studies are the first to examine emotional clarity as a function of valence,
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
16
and the findings from both studies highlight the importance of this distinction. Using a set of common
items assessing negative and positive emotion in the two studies, we documented that emotional clarity is
related only to levels of negative emotion. It is possible, of course, that different mechanisms underlie
emotional clarity for positive and negative emotions, and this issue should be examined more explicitly in
future research.
Given that neuroticism is a risk factor for MDD (Barlow et al., 2013), another direction for future
research is to examine whether reduced clarity of negative emotion predicts the onset of this disorder. We
cannot examine this question in Study 1 because we do not know which, if any, of the participants had
experienced a major depressive episode of in their past, were in a depressive episode at the time of the
study, or may experience an episode in the future. Future research should also examine longitudinally
whether clarity of negative emotion diminishes after the onset of a major depressive episode and/or
increases after individuals experience remission from depression. If predictive, RTs to negative emotion
items could be an easy way to assess future risk for mood disorder such as MDD. Such RTs can easily be
collected online and could be used as a diagnostic indicator for possible mood dysregulation. Further
research is needed to examine the diagnostic utility of such RTs however.
Only Lischetzke and colleagues (2011) used methods other than global self-reports to assess
emotional clarity. Our paper extends Lischetzke et al.’s findings in two important ways. First, these
investigators administered emotion items with bipolar scales (e.g., relaxed--nervous); in contrast, we
administered emotion items with unipolar scales. Our use of unipolar items is important because it lays
bare the valence-specificity of emotional clarity. Indeed, the findings from Study 1 illustrate that
emotional clarity is not always diminished across all emotions, but can be specific to an emotional
valence. Second, Lischetzke et al. found that people’s RTs to emotion items were related to how certain
they felt about their emotions in the moment, but not to global emotional clarity scores; RTs to emotion
items were also correlated with people’s self-reported success of subsequent emotion regulation.
Consistent with Lischetzke et al.’s findings, we found in Study 2 that RTs were generally not related to
self-reports of global emotional clarity.
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
17
Using an indirect assessment of emotional clarity is particularly important when assessing clinical
samples, such as individuals diagnosed with MDD. RTs should be less influenced by cognitive biases
than are more volitional self-reports of emotional clarity. Although we were able to minimize biases in
self-report, some individuals with MDD can exhibit psychomotor retardation. In our main analyses we
controlled for varying baseline RTs at the within-person level. However, our pattern of findings did not
differ when baseline RT was also included at the between-person level. Although the MDD participants
were slower than the CTL participants to respond to all experience sampling items, they were even slower
to respond to the emotion items.
In addition to including baseline RT in our multilevel models, we controlled for the levels at
which people endorsed emotions in our analyses. This is important because increased levels of negative
emotion are a defining feature of neuroticism. Moreover, increased negative emotion and decreased
positive emotion are diagnostic criteria for MDD (American Psychiatric Association, 2013), with a large
body of evidence documenting this pattern of affective functioning in individuals diagnosed with MDD
(e.g., Peeters et al., 2006). People who are experiencing higher levels of negative or positive emotion may
take longer to evaluate the specific level at which they are feeling the emotions than do people who are
not experiencing any negative or positive emotion. Our results suggest that as levels of negative emotion
increase, adults with average levels of neuroticism (Study 1) and without mental health problems (Study
2) take longer to rate the specific levels at which they are experiencing negative emotion (i.e., have less
clarity about negative emotion). RTs also increase as levels of negative emotion increase for people with
higher levels of neuroticism and for those with MDD, but significantly less than is the case for healthier
individuals. This was an unexpected pattern of results, and future research is needed to better understand
how the relations between levels of emotion and clarity of emotion vary based on the levels of current
emotion. For positive emotion, our results suggest that all people (independent of their levels of
neuroticism or their MDD status), take longer to rate the levels at which they are experiencing positive
emotion as their actual levels of positive emotion increase (as happens for negative emotion). That is,
people’s clarity of positive emotions decreases with increasing positive emotion. Although the relation
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
18
between level of positive emotion and RT to positive emotion items is significant, the magnitude of this
association is lower than that of the relation between negative emotion and RTs to negative emotion
items, underscoring the importance in future research of taking into account the levels at which people are
endorsing emotion items when using RTs to assess emotional clarity.
Despite the methodological strengths and the importance of findings from these studies, there are
four limitations of this research. First, the sample in Study 1 comprised largely students and, in Study 2,
adults up to 40 years of age. Therefore, investigators should examine whether neuroticism and MDD are
associated with decreased clarity of negative emotions in older adults. Second, despite consistent findings
concerning the clarity of negative emotions across two studies with diverse samples, it is not clear
whether the lower clarity of negative emotions in participants with neuroticism or MDD reflects a
labeling issue or whether their actual emotional experience is amorphous, which should be examined in
future research. Third, the three negative emotions (angry, sad, anxious) varied across arousal and
approach/avoidance domains, whereas the two positive emotions (happy, excited) were both fairly high-
arousal and more approach-oriented emotions. Consequently, participants may have had to make more
distinctions for the negative than for the positive items, which may have made it more difficult to rate
negative than positive emotions. Future research should examine whether the present findings are
replicated if the arousal and approach/avoidance domains are better represented among positive emotions.
Finally, in Study 2, as noted above, RTs to emotion items were largely unrelated to the global emotional
clarity (with one exception: for the CTL group, RTs to positive emotion items were positively related to
global emotional clarity, which was in the opposite direction as expected.) On the one hand, these
findings question the validity of using RTs as a measure of emotional clarity. On the other hand,
Lischeske and colleagues (2011) conducted a rigorous assessment validating this indirect method to
assess emotional clarity. Further, although it is reasonable to expect that different measures of emotion to
converge, correlations between measures of emotions are “moderate at best, small in typical studies and
inconsistent across studies” (Mauss & Robinson, 2009, p. 227). Regardless, it will be important for future
researchers to attend to issues of validity when examining emotional clarity.
EMOTIONAL CLARITY, NEUROTICISM, AND MDD
19
In sum, across two independent naturalistic studies, we found consistent evidence that negative
emotionality, conceptualized as both a disposition (neuroticism) and a state (MDD) is related to decreased
clarity of negative, but not of positive, emotions in daily life. These results highlight the importance of
examining emotional clarity separately by valence. In these studies, we used a validated assessment
method and utilized statistical techniques appropriate to the research questions and to analyses of
experience sampling data. Negative emotions often communicate whether people’s goals, needs and
concerns are not being met. In this context, the results of these studies contribute to a growing
understanding of the emotional disturbances that characterize neuroticism and MDD, and implicate
difficulties in clarity of negative emotions in both of these disruptive forms of distress.

Figure 1. Aggregated within-person reaction times (prompt level, z-scored). Panel A presents results from
Study 1, separately for low (-1 SD below mean) versus high (+1 SD above the mean) levels of
neuroticism. Panel B presents results from Study 2 by depression group (CTL = healthy control group;
MDD = Major Depressive Disorder group), with error bars representing 95% confidence intervals.
