It was hypothesized that self-and informant reports of self-critical perfection-ism would correlate moderately and that self-and informant reports of self-critical perfectionism would predict increases in depressive symptoms over time. A sample of 155 target participants and 588 infor-mants was recruited and studied using a prospective longitudinal design. All study hypotheses were supported, including evidence that self-and informant reports of self-critical perfectionism each add incrementally to the understanding of the self-critical perfectionism–depressive symptoms connection. Informant reports may provide a more complete picture of the self-critical perfectionist and her or his vulnerability to depressive symptoms.

abstract
Perfectionism is a putative risk factor for depressive symptoms. However, most research in this area uses
cross-sectional designs (which fail to address temporal precedence) and mono-source designs (which are
influenced by various biases). The present study overcomes these limitations by using a novel design
involving both self- and informant reports of self-critical perfectionism (i.e., negative reactions to per-
ceived failures, concern over others’ criticism and expectations, doubts about performance abilities,
and intense self-rebuke). It was hypothesized that self- and informant reports of self-critical perfection-
ism would correlate moderately and that self- and informant reports of self-critical perfectionism would
predict increases in depressive symptoms over time. A sample of 155 target participants and 588 infor-
mants was recruited and studied using a prospective longitudinal design. All study hypotheses were
supported, including evidence that self- and informant reports of self-critical perfectionism each add
incrementally to the understanding of the self-critical perfectionism–depressive symptoms connection.
Informant reports may provide a more complete picture of the self-critical perfectionist and her or his
vulnerability to depressive symptoms.

1. Introduction
Perfectionism is a putative risk factor for depressive symptoms.
Evidence suggests this link persists after controlling for established
predictors of depressive symptoms such as neuroticism (Mackinnon
et al., 2012). Notwithstanding, major gaps still exist in our under-
standing of the perfectionism–depressive symptom connection.
Nearly all studies in this area use cross-sectional, mono-
source designs. Cross-sectional designs fail to address temporal
precedence. Mono-source designs are potentially problematic,
especially when studying undesirable or maladaptive traits
(Klonsky, Oltmanns, & Turkheimer, 2002). Self-report question-
naires assessing people high in perfectionism may be influenced
by self-presentational biases (e.g., appearing perfect) or defensive
responses that promote or conceal certain traits. People high in
perfectionism may become so accustomed to their behavior
(e.g., unrealistic self-expectations) that they fail to accurately
recall or report it. Informant reports can overcome biases in or
limitations of self-perceptions (Vazire, 2006). For example, infor-
mant ratings of perfectionism help to bypass self-enhancing or
self-deprecating biases.
We know of only one perfectionism study involving informants
(Flett, Besser, & Hewitt, 2005). These authors used a cross-
sectional, single informant design where one friend informed on
the other; they found self- and informant reports of perfectionism
were correlated with each other and with depressive symptoms.
Although this study improved on mono-source designs, multiple
informants produce a more reliable, encompassing assessment of
target participants’ traits (Vazire, 2006). Multiple informants par-
ticipate in various roles and situations with target participants;
for example, romantic partners observe different behaviors than
coworkers.
Our study overcomes limitations of prior research. Specifically,
we collected self-reports of perfectionism as well as informant
reports of perfectionism from multiple sources and tested whether
these reports predicted longitudinal increases in depressive
symptoms.

1.1. Self-critical perfectionism and depressive symptoms
Three prominent theoretical models in perfectionism research
include psychodynamic models (Blatt, 1995), cognitive-behavioral
models (Frost, Marten, Lahart, & Rosenblate, 1990), and interper-
sonal models (Hewitt & Flett, 1991). Self-critical perfectionism
(negative reactions to perceived failures, concern over others’ crit-
icism and expectations, doubts about performance abilities, and
intense self-rebuke) represents a theoretically based, empirical
synthesis of these models (Dunkley, Zuroff, & Blankstein, 2003).
Self-critical perfectionism is conceptualized as a risk factor that
comes before and contributes to increases in depressive symptoms.
Consistent with this conceptualization, clinical observations (Blatt,
1995) and empirical findings (Dunkley et al., 2003; McGrath et al.,
2012) suggest self-critical perfectionism encapsulates core attri-
butes (e.g., harsh self-criticism) and central preoccupations (e.g.,
evaluative fears) of people at risk for depressive symptoms.
Building upon Flett et al. (2005), we hypothesized Wave 1 self-
and informant reports of self-critical perfectionism would correlate
moderately. We also hypothesized Wave 1 informant reports of
self-critical perfectionism would predict Wave 2 depressive symp-
toms after controlling for Wave 1 self-reports of self-critical perfec-
tionism and Wave 1 depressive symptoms. Based on McGrath et al.
(2012), we hypothesized Wave 1 self-reports of self-critical perfec-
tionism would predict Wave 2 depressive symptoms after control-
ling for Wave 1 informant reports of self-critical perfectionism and
Wave 1 depressive symptoms. These hypotheses draw on research
suggesting each source (self- and informant reports) has unique
information to convey that is important in predicting depressive
symptoms (Vazire, 2006).
2. Method
2.1. Participants
A sample of 155 undergraduates (119 women) was recruited
from Dalhousie University. Participants averaged 20.65 years of
age (SD = 3.03) and were mostly (70.3%) of European descent. We
call these 155 participants targets. A sample of 588 participants
(364 women) was recruited from friends, family, etc. of targets.
We call these 588 participants informants; 39.3% of informants
were friends, 16.3% were mothers, 9.7% were fathers, and 34.7%
were involved in other types of relationships with targets (e.g., girl-
friend). Informants averaged 30.20 years of age (SD = 14.82), and
were mostly (73.3%) of European descent. Informants indicated
they had face-to-face contact with targets an average of 3.70 days
per week (SD = 2.57) and had some other form of contact with tar-
gets (e.g., phone) an average of 5.13 days per week (SD = 2.05).
Most informants (50.9%) reported they knew targets ‘‘extremely
well’’ (M= 3.39, SD = 0.72) on a 5-point scale from 1 (not at all)to
5(extremely well). Informants indicated the average length of their
relationship with targets was 10.46 years (SD = 8.97).
2.2. Measures
2.2.1. Self-critical perfectionism
Self-critical perfectionism was measured using the 9-item self-
criticism subscale (SC; e.g., ‘‘I often find I don’t live up to my
ideals’’) of the Depressive Experience Questionnaire (DEQ; Bagby,
Parker, Joffe, & Buis, 1994), the 5-item short form of the concern
over mistakes subscale (COM; e.g., ‘‘If I fail at school, I am a failure
as a person’’) of Frost’s Multidimensional Perfectionism Scale (FMPS;
Frost et al., 1990), the 4-item doubts about actions subscale (DAA;
e.g., ‘‘I have doubts about the things I do’’) of the FMPS, and the
5-item short form of the socially prescribed perfectionism subscale
(SPP; e.g., ‘‘My family expects me to be perfect’’) of Hewitt and
Flett’s Multidimensional Perfectionism Scale (HFMPS; Hewitt & Flett,
1991). Studies support the reliability and validity of these sub-
scales (McGrath et al., 2012).
Informant reports of self-critical perfectionism were assessed
with modified versions of the DEQ-SC, FMPS-COM, FMPS-DAA,
and HFMPS-SPP. Self-report items (e.g., ‘‘People expect more from
me than I am capable of giving’’) were modified into informant re-
port items (e.g., ‘‘They believe that people expect more from them
than they are capable of giving’’). The number of items (e.g., five
items for the socially prescribed perfectionism subscale) and the
item response options (e.g., 1 = strongly disagree;7=strongly agree)
were unmodified for informant measures. These four informant
measures were created for the present study. Research on their
reliability and validity is therefore unavailable.
2.2.2. Depressive symptoms
Depressive symptoms were measured using the 7-item depres-
sion subscale (e.g., ‘‘I felt down-hearted’’) of the Depression Anxiety
Stress Scale (DASS-D; Lovibond & Lovibond, 1995). Evidence sup-
ports the reliability and validity of this subscale, including research
suggesting the DASS-D specifically measures depressive symptoms
apart from anxiety symptoms and stress (Lovibond & Lovibond,
1995).
2.3. Procedure
Dalhousie University’s Ethics Board approved this study. Our
study involved two waves separated by 28 days. Targets completed
measures of self-critical perfectionism at Wave 1 and measures of
depressive symptoms at Wave 1 and 2. Informants completed
measures of self-critical perfectionism at Wave 1. After Wave 2,
targets received $30 and a 3.0% bonus credit toward a psychology
course or $45; informants were entered in 1 of 20 draws for $50.
Targets provided a list of five informants before starting our study.
Informants met three inclusion criteria: knowing the target for at
least three months, interacting with the target at least twice a
week, and knowing the target reasonably well. Informants were
contacted via email and invited to complete an internet-based
questionnaire. Informants were emailed three times to maximize
participation. Not all informants who were invited to participate
completed our study, meaning the number of informants per target
varied somewhat; 75.9% (588 of 775) of informants invited to par-
ticipate completed our study. For each target, there was an average
of 3.89 informants (SD = 1.36). Overall, 155 (100%) targets finished
Wave 1 and 152 targets (98.1%) finished Wave 2. Not all targets
completed Wave 2 exactly when requested (i.e., 28 days after
Wave 1). On average, Wave 2 occurred 30.11 (SD = 1.88) days after
Wave 1.
2.4. Data analysis
Missing data were minimal for targets and informants (<2.5%).
We imputed missing data with an expectation maximization algo-
rithm. Hierarchical multiple regression analyses were also used to
test hypotheses.
3. Results
3.1. Descriptive statistics
Means for self-report measures were within one standard devi-
ation of means from past studies of undergraduates (McGrath
et al., 2012), indicating consistency with past studies using similar
samples. Alpha reliabilities for self- and informant report measures
958 S.B. Sherry et al. / Personality and Individual Differences 54 (2013) 957–960
were acceptable (P.86; see Table 1); alpha reliabilities for self-
report measures resembled prior work (McGrath et al., 2012).
Comparison means and alphas for informant report measures are
not available as our study represents the first time these informant
report measures have been used.
3.2. Correlations
Indicators of self-critical perfectionism were standardized and
summed before analyses. We aggregated across informant reports
since aggregation of reports from multiple informants leads to
more reliable assessments of personality (Vazire, 2006). For exam-
ple, if informant reports from a roommate, friend, mother, and girl-
friend were available for a target participant, then we combined all
four reports into one aggregated informant report. This resulted in
151 aggregated informant reports, meaning 97.4% of our 155 tar-
gets provided us with at least one informant.
As hypothesized, Wave 1 self- and informant reports of
self-critical perfectionism were correlated (see Table 1). Wave 1
self- and informant reports of self-critical perfectionism were also
correlated with Wave 1 and 2 depressive symptoms.
3.3. Hierarchical multiple regression analyses
As Panel 1 of Table 2 shows, a hierarchical multiple regression
analysis was conducted with Wave 2 depressive symptoms as
the outcome. Wave 1 depressive symptoms were entered as a pre-
dictor in Step 1, followed by Wave 1 self-critical perfectionism
(self-report) in Step 2, and Wave 1 self-critical perfectionism
(informant report) in Step 3. As hypothesized, Wave 1 informant
reports of self-critical perfectionism significantly predicted incre-
mental variance in Wave 2 depressive symptoms after controlling
for Wave 1 self-reports of self-critical perfectionism and Wave 1
depressive symptoms.
As Panel 2 of Table 2 illustrates, another hierarchical multiple
regression analysis was conducted with Wave 2 depressive symp-
toms as the outcome. Wave 1 depressive symptoms were entered
as a predictor in Step 1, followed by Wave 1 self-critical perfection-
ism (informant report) in Step 2, and Wave 1 self-critical perfec-
tionism (self-report) in Step 3. Consistent with hypotheses, Wave
1 self-reports of self-critical perfectionism significantly predicted
incremental variance in Wave 2 depressive symptoms even after
controlling for Wave 1 informant reports of self-critical perfection-
ism and Wave 1 depressive symptoms.
4. Discussion
Though self-perceptions can be accurate, a person’s position as
expert on his or her traits can be compromised by biases (e.g., self-
serving biases). Using self-report questionnaires, Dunkley et al.
(2003) and McGrath et al. (2012) found that people high in self-
critical perfectionism are at risk for depressive symptoms. Our
study complements and extends this research by showing that
(a) self- and informant reports of self-critical perfectionism were
moderately correlated and (b) self- and informant reports of self-
critical perfectionism each add incrementally to the understanding
of the perfectionism-depressive symptoms connection.
Our study supported the convergent validity of the self-critical
perfectionism construct by demonstrating self- and informant
reports correlated moderately (r= .35). This finding is congruent
with Flett et al. (2005), who found self- and informant reports
of perfectionism correlated moderately in a single informant
study where one friend informed on the other. This finding also
intersects with a wider literature suggesting self- and informant

reports of disordered personality traits correlate moderately
(Klonsky et al., 2002).
Self-critical perfectionism represents a constellation of traits
with salient self-evaluative features (e.g., intense self-reproach)
and social-cognitive features (e.g., perceiving that others demand
perfection of oneself). These traits may be conceptualized as inter-
nal mental representations of the self and other people (Blatt,
1995). So, what is it informants see when they think they see a per-
fectionist? Informants may be directly observing (or indirectly
inferring) targets’ self-critical perfectionism through verbally ex-
pressed self-criticism, repetitive checking behaviors, or overt inter-
personal behaviors with perfectionistic themes (e.g., complaints
regarding pressures from others).
Results also indicated informant reports of self-critical perfec-
tionism provide information that is non-redundant with self-
reports of self-critical perfectionism. Wave 1 informant reports of
self-critical perfectionism predicted Wave 2 depressive symptoms
after controlling for Wave 1 self-reports of self-critical perfection-
ism and Wave 1 depressive symptoms, thereby supporting our
hypothesis. These analyses represent a strict test of the self-critical
perfectionism–depressive symptoms connection and support our
assertion self-critical perfectionism may be a premorbid personal-
ity structure that places people at risk for depressive symptoms
(McGrath et al., 2012). Researchers and clinicians should be aware
informant reports of self-critical perfectionism can contribute
incrementally to the understanding of participants and patients.
Tests of self-critical perfectionism as a risk factor for depressive
symptoms are scarce. Consistent with Dunkley et al. (2003), McG-
rath et al. (2012), and our hypotheses, Wave 1 self-reports of self-
critical perfectionism predicted Wave 2 depressive symptoms after
taking into account Wave 1 informant reports of self-critical per-
fectionism and Wave 1 depressive symptoms. Our research also
converges with Dunkley et al. (2003) and McGrath et al. (2012)
to suggest aggregating multiple, lower-order perfectionism facets
into a single, higher-order perfectionism domain (i.e., self-critical
perfectionism) represents one effective way to operationalize the
perfectionism construct.
Our study has limitations. Our sample was primarily female and
Caucasian. It is unclear whether our results generalize to other
samples. Informants were not selected randomly from targets’ so-
cial networks. Targets may have selected informants who viewed
them positively. We also did not collect informant reports of
depressive symptoms, meaning our outcome variable is more
susceptible to self-report biases. Moreover, informants reported
on targets’ internal traits; some of these traits could not be directly
observed (e.g., self-criticism). Informants may be better judges of
external traits (e.g., behaviors) compared to internal traits (e.g.,
thoughts). Informants are also not without potential biases (e.g.,
parents might have ego-protective biases in reporting on children)
or informants may simply lack information about targets.
Self-reports are subject to biases (e.g., defensive responses)
which may compromise the accuracy of information obtained, espe-
cially for participants with undesirable or maladaptive traits such
as self-critical perfectionism (Klonsky et al., 2002). In our study,
self- and informant reports of self-critical perfectionism converged
moderately, and both approaches to assessing self-critical perfec-
tionism predicted longitudinal increases in depressive symptoms.

... Research has established that there is modest correspondence between self-reports and informant ratings of perfectionism (Mushquash, Sherry, Sherry, & Allen, 2013;Vieth & Trull, 1999), and some evidence points to the relevance of informant ratings in terms of associations with measures of maladjustment. For example, Sherry et al. (2013) showed that informant ratings of perfectionism provide unique variance beyond self-reports of perfectionism in predicting depression, and, most notably, Flett, Besser, and Hewitt (2005) showed in their research with 210 pairs of community participants and their same-sex best friends who served as informants that the associations between perfectionism and distress varied substantially depending on whether the focus was on selfreports or on informant ratings. In particular, certain findings were only evident based on analyses of informant ratings and not the self-ratings, suggesting that informants and participants are focusing on somewhat different features of perfectionism. ...
... For example, Flett et al. (2005) found that self-reported levels of other-oriented perfectionism were not associated with depression, whereas informant ratings of target other-oriented perfectionism were associated with depression. Similarly, Sherry et al. (2013) found that self-and informant-reports each added incrementally to the prediction of depression, suggesting that the various reports shared some aspects of perfectionism and also captured unique elements of perfectionism. Although it is not entirely clear why differences between informant-and self-report exist, there appears to be agreement among researchers that differences could arise from targets and informants focusing on different elements of the target's perfectionistic behavior. ...
... However, the converging and contrasting findings between our study and Hewitt et al.'s (2015) suggest that close other informants can provide unique and useful information on transdiagnostic personality vulnerabilities such as personality traits and tendencies among adults. Moreover, other research on the perfectionism construct (Mushquash et al., 2013) and its role in depression (Flett et al., 2005;Sherry et al., 2013) found that informant ratings provide a valid method for assessing unique elements of perfectionism that are not found with self-reports. Thus, close other ratings may provide not only a multimethod approach to evaluating outcomes but also a broader evaluation of outcomes from a particular treatment. ...

Clinical Impact Statement Perfectionism is a pernicious personality vulnerability factor associated with myriad forms of distress and psychological disorders. Question: This article attempts to determine whether close other informants (e.g., spouses) can perceive and rate improvements in perfectionism components in patients undergoing a dynamic-relational group treatment for perfectionism, to provide further evidence of the effectiveness of this treatment for perfectionism. Findings: Consistent with findings of change in perfectionism based on self-report measures (Hewitt et al., 2015), there was good support for the effectiveness of the treatment based on close other measures of changes in perfectionism. Meanings: This underscores the utility of this treatment and indicates the importance of focusing treatment on relational underpinning of perfectionism. Moreover, the article also supports the use of close others in evaluating treatment effectiveness because they may be perceiving elements of perfectionistic behavior that the patients themselves do not perceive. The main conclusions of this study are that the treatment appears to have support as being an appropriate and effective treatment for perfectionism and that close others may be a valuable resource in assessing changes in patients’ functioning from treatment. Next Steps: Future work should continue to evaluate the efficacy of this treatment modality and also evaluate the utility of using close others in both psychotherapy research and in the treatment of perfectionistic individuals.
... Multidimensional perfectionism research suffers from an over-reliance on mono-source, self-report questionnaires (Sherry et al., 2013). This is partly due to the proliferation of self-report perfectionism scales. ...
... For example, informant reports may assist in bypassing self-enhancing or self-deprecating responding in perfectionists. There are very few multidimensional perfectionism studies where informants are used as data sources, and these studies suggest that self-and informant reports of perfectionism dimensions are moderately correlated and that informant reports add incrementally to our understanding of outcomes beyond self-reports of perfectionism dimensions (Sherry et al., 2013;Nealis et al., 2016). More studies involving informants are needed in perfectionism research to produce a more reliable, encompassing assessment of perfectionists. ...

Theory and evidence converge to suggest perfectionism is a personality construct that matters a great deal and is linked with many consequential outcomes (e.g., depression, eating disorders, suicide, marital problems, and procrastination). With the multidimensional perfectionism construct turning 30 years of age, our review critically examines the past and the future of this construct with a focus on the six landmark dimensions of Hewitt and Flett’s (1991) and Frost et al.’s (1990) seminal models: self-oriented perfectionism, other-oriented perfectionism, socially prescribed perfectionism, personal standards, concerns over mistakes, and doubts about actions. Our review considers both what we understand about these dimensions given the extant empirical literature (i.e., known knowns) and areas where gaps exist in our understanding of multidimensional perfectionism and its consequences (i.e., known unknowns). Evidence suggests the core dimensions of Hewitt and Flett’s (1991) and Frost et al.’s (1990) trait and attitudinal models of perfectionism, respectively, are neither captured by nor redundant with other well-established predictors. In fact, these perfectionism dimensions appear to represent core vulnerability factors that are tied intimately to the development and maintenance of a wide range of maladaptive outcomes.
... Discrepancy here is assessed by a questionnaire item such as, "To what extent do you fall short of other people's expectancies?" Research has linked this type of interpersonal discrepancy with a host of negative outcomes that are associated with socially prescribed perfectionism (e.g., Mushquash & Sherry, 2012;Sherry et al., 2013;Sherry & Hall, 2009;Sherry, Sabourin, et al., 2014). Individual differences in this discrepancy are clearly meaningful. ...

Perfectionism is a multidimensional personality construct with various components. Socially prescribed perfectionism (i.e., perceived social pressures and expectations to be perfect) is one key element. This trait dimension represents a chronic source of pressure that elicits feelings of helplessness and hopelessness at extreme levels. Unfortunately, at present, the destructiveness of socially prescribed perfectionism has not been fully recognized or extended conceptually despite the extensive volume of research on this dimension. To address this, we first trace the history and initial conceptualization of socially prescribed perfectionism. Next, we summarize and review findings that underscore the uniqueness and impact of socially prescribed perfectionism, including an emphasis on its link with personal, relationship, and societal outcomes that reflect poor mental well-being, physical health, and interpersonal adjustment. Most notably, we propose that socially prescribed perfectionism is a complex entity in and of itself and introduce new conceptual elements of socially prescribed perfectionism designed to illuminate further the nature of this construct and its role in distress, illness, dysfunction, and impairment. It is concluded that socially prescribed perfectionism is a significant public health concern that urgently requires sustained prevention and intervention efforts.
... Although we controlled for the shared variance of self-report measures by taking into account baseline scores, common method-variance might inflate the identified relations (Campbell & Fiske, 1959;Podsakoff, Whiting, Welsh, & Mai, 2013). Informant reports add incrementally to understanding the consequences of perfectionism (e.g., Sherry et al., 2013) and may also inform the quest for its origins. Thus, future studies on the perfectionism-global self-esteem relation are needed that use multiple measurement methods (e.g., reports from parents or friends). ...

Perfectionism is a multidimensional personality trait whose facets differentially relate to indicators of psychological functioning, such as global self-esteem. There has been some theoretical disagreement whether perfectionism affects global self-esteem, or vice versa. This question merits renewed attention due to increasing efforts to prevent the development of maladaptive perfectionism facets in adolescents. Additionally, recent research has indicated a role of self-esteem for predicting personality development. This study aimed to clarify the longitudinal relations of multidimensional perfectionism and global self-esteem. A sample of 707 early adolescents participated in two measurement points two years apart. Global self-esteem positively predicted personal standards, negatively predicted doubts about actions, and did not predict concern over mistakes beyond baseline. Perfectionism facets did not longitudinally predict global self-esteem. These findings provide the first evidence for a role of global self-esteem in perfectionism development. Addressing early adolescents’ self-esteem may aid in preventing the development of maladaptive perfectionism facets.
... First, the cross-sectional design of this study precludes inferences with respect to temporal precedence and causality concerning associations between perfectionistic cognitions and chronic inflammatory processes. Core vulnerability models of perfectionism (Hewitt, Flett, & Ediger, 1996) and the cognitive theory of perfectionism Flett et al., 2016) posit that chronically engaging in perseverative thinking about the need to be perfect and past failure experiences can exact a toll on health Flett et al., 2016 (Sherry et al., 2013). Fourth, whereas we focused on individual differences in perfectionistic cognitions given theory and empirical research, which support that individual differences in perfectionistic cognitions uniquely set the stage for poorer outcomes over and above multidimensional trait measures of perfectionism (Casale et al., 2020), researchers are encouraged to test associations between perfectionism and pro-inflammatory markers with other measures of perfectionism such as Hewitt and Flett's (1991) or Frost et al.'s (1990) Multidimensional Perfectionism Scale. ...

Previous research has demonstrated that perfectionism is implicated in poorer health and earlier mortality. However, to our knowledge, research has not yet determined how individual differences in perfectionistic cognitions are related to intermediary health markers such as inflammation. Thus, within the theoretical frameworks of the perfectionism diathesis-stress model (Hewitt & Flett, 1993) and the cognitive theory of perfectionism (Flett, Hewitt, Nepon, & Besser, 2018; Flett, Nepon, & Hewitt, 2016) the aims of our study were to test whether individual differences in perfectionistic cognitions were associated with low-grade inflammation via c-reactive CRP and IL-6 biomarkers and whether these relationships varied as a function perceived stress. The sample included 248 Canadian young adults (52% female, Mage = 22.89, SD = 1.53) who completed surveys assessing key constructs such as perfectionistic cognitions and perceived stress along with providing assessments of body fat percentage and serum samples of IL-6 and CRP. Regression analyses indicated that perfectionistic cognitions were not related to IL-6 under any conditions of stress. However, under high levels of stress perfectionistic cognitions were associated with elevated levels of CRP and these findings held after accounting for the effects of smoking status, body fat percentage, and respondent sex. The present work adds to the growing body of evidence supporting links between personality and inflammation. These findings raise the possibility that experiencing more frequent thoughts centered on the need to be perfect when coupled with higher levels of stress may set the stage for greater vulnerability for chronic inflammation.
... Studies on clinical and community samples have shown that there is a significant relationship between perfectionism and depression, and the occurrence of maladaptive perfectionism is usually earlier than depression (61)(62)(63). This situation will be gradually aggravated during the individual development (64). ...

Background: The prevalence of depression among Chinese college students tends to be higher in recent years, which has caused a series of negative effects in their lives. One of the factors is perfectionism, and few researches have been conducted to examine the role of self-compassion in perfectionism and depression link. The purpose of the study was to explore the relationships between perfectionism, self-compassion, and depression in the context of Chinese undergraduates. Methods: The anonymous self-reported questionnaires including three scales on perfectionism, selfcompassion, and depression were utilized in the study. A total of 540 undergraduates were recruited from three universities in Nanjing and Xi'an by using convenient cluster sampling and were required to complete the questionnaires. Pearson correlation analysis was used to examine the correlation between variables. Multiple linear regression analysis was used to examine the predictive effects of perfectionism and selfcompassion on depression. Hierarchical multiple regression analysis was used to evaluate the mediating effect of self-compassion. Results: Regression analyses demonstrated that the maladaptive perfectionism was positively associated with depression, while adaptive perfectionism and self-compassion were negatively associated with depression. The mediation tests showed that the self-compassion partially mediated the relationship between the two types of perfectionism and depression. Conclusions: This study revealed the mediating effect of self-compassion in the relation between perfectionism and depression in Chinese undergraduates. Self-compassion is likely to be an effective psychological intervention method to relieve the depressive symptoms in college students, and further study is needed to verify this possibility.
... Using only self-reports of alcohol related outcomes can be biased through impression management, lack of insight, social desirability, and/or self-deception (Davis, Thake, & Vilhena, 2009). Informant-reports can add incrementally to our understanding of various mental health problems above and beyond selfreports (Sherry, Nealis, Macneil, Stewart, & Sherry, 2013), and have been shown to be beneficial and accurate within romantic couples (Sherry et al., 2014). Therefore, using informant-reports of alcohol problems in romantic dyads could potentially provide information an individual is unaware of or unwilling to provide. ...

Alcohol problems are not just an individual concern; they have important negative impacts on romantic relationships. Perceiving one's romantic partner to have an alcohol problem is associated with lower relationship satisfaction and commitment. However, the utility of informant-reports of a partner's alcohol problems in predicting future dyadic conflict remains unknown. Our objective was to test the incremental validity of informant-reports of a partner's alcohol problems in predicting escalations in dyadic conflict over a one-month period beyond the partners' self-reported alcohol problems. One-hundred-eighty-seven opposite-sex couples participated in a one-month longitudinal study involving self- and informant-reports of alcohol problems at baseline and dyadic conflict measures at baseline and one-month follow-up. We hypothesized that, in both sexes, informant-reports of a partner's alcohol problems would predict escalations in dyadic conflict above and beyond the variance explained by self-reports of alcohol problems. This hypothesis was partially supported. Informant-reports of a partners' alcohol problems incrementally predicted future dyadic conflict, but only when women were informants. Women's self-reports of their own alcohol problems also predicted escalations in dyadic conflict whereas men's self-reports did not. Findings suggest that having women report on both their own and their male partners' levels of alcohol-related problems may help identify at-risk couples for early intervention to prevent escalating dyadic conflict. Though self-reported alcohol problems can be accurate, a person's position as expert on his or her alcohol problems can be compromised by biases (e.g., self-deception). Informant-reports may provide a more complete picture of the problem drinker in the romantic relationship context.

The present study examined whether cultural differences in different dimensions of perfectionism exist and whether different dimensions of perfectionism (i.e., rigid and self-critical perfectionism) predicted different dimensions of test anxiety while controlling for depression in a sample of Canadian and Singapore higher education students. In addition, culture was examined to determine whether it served as a moderator variable in the relationship between different dimensions of perfectionism and different dimensions of test anxiety. The present study was grounded in DiBartolo and Rendón’s cross-cultural framework for conducting intra- and intercultural research in the area of perfectionism. The sample for the study included 1,095 undergraduate students. Perfectionism, test anxiety, and depression measures were administered to the students online. The results of mean and covariance analyses found the perfectionism measure was invariant across Canadian and Singapore students. In addition, the results of latent mean analyses found no significant differences on the different dimensions of perfectionism between Canadian and Singapore students. The results of analyses of variance also found no significant differences in different ethnic groups on the different dimensions of perfectionism in Canada and Singapore. Furthermore, the results of five hierarchical regression analyses found self-critical perfectionism explained unique variance in the five different test anxiety dimensions while controlling for depression, and culture did not serve as a moderator variable in the relationship between the different dimensions of perfectionism and test anxiety. Implications of the findings are discussed.

Initial research suggests that parental perfectionism is central to the development of athlete perfectionism. However, it is unclear whether perceived or actual parental perfectionism is most important. The present study aimed to address this issue in two ways. First, we reexamined the predictive ability of actual versus perceived parental perfectionism on athlete perfectionism. Second, for the first time, we tested whether perceived parental perfectionism mediated the relationship between actual parental perfectionism and athlete perfectionism. A sample of 150 junior athletes and their parents completed measures of perfectionism (perfectionistic strivings and perfectionistic concerns). Junior athletes completed two measures, one of their own perfectionism and one of perceptions of their parents' perfectionism. Parents completed one measure of their own perfectionism. Regression analyses showed that perceived parental perfectionism predicted athlete perfectionism over and above actual parental perfectionism. Mediation analyses provided support for our proposed model. Overall, the findings suggest that both actual and perceived parental perfectionism are important in the development of perfectionism in junior athletes.

Background: Case histories, theoretical accounts, and empirical studies suggest an important relationship between perfectionism and bulimic symptoms. However, whether perfectionism confers vulnerability for bulimic symptoms is unclear. Objective: To address this, we conducted a meta-analysis testing if socially prescribed perfectionism, concern over mistakes, doubts about actions, personal standards, self-oriented perfectionism and EDI-perfectionism predict increases in bulimic symptoms over time. Method: Our literature search yielded 12 longitudinal studies for inclusion. Samples were composed of adolescents , undergraduates, and community adults. Results: Meta-analysis using random effects models showed perfectionistic concerns and EDI-perfectionism, but not perfectionistic strivings, had positive relationships with follow-up bulimic symptoms, after controlling for baseline bulimic symptoms. Conclusion: Results lend credence to theoretical accounts implicating perfectionism in the development of bulimic symptoms. Our review of this literature also underscored the need for additional longitudinal studies that use multisource designs and that assess perfectionism as a multidimensional construct.

According to the social disconnection model, perfectionistic concerns (i.e., harsh self-scrutiny, extreme concern over mistakes and others' evaluations, and excessive reactions to perceived failures) confer vulnerability to depressive symptoms indirectly through interpersonal problems. This study tested the social disconnection model in 226 heterosexual romantic dyads using a mixed longitudinal and experience sampling design. Perfectionistic concerns were measured using three partner-specific self-report questionnaires. Conflict was measured as a dyadic variable, incorporating reports from both partners. Depressive symptoms were measured using a self-report questionnaire. Perfectionistic concerns and depressive symptoms were measured at Day 1 and Day 28. Aggregated dyadic conflict was measured with daily online questionnaires from Days 2 to 15. Data were analyzed using structural equation modeling. There were four primary findings: (a) Dyadic conflict mediated the link between perfectionistic concerns and depressive symptoms, even when controlling for baseline depressive symptoms; (b) depressive symptoms were both an antecedent and a consequence of dyadic conflict; (c) perfectionistic concerns incrementally predicted dyadic conflict and depressive symptoms beyond neuroticism (i.e., a tendency to experience negative emotions) and other-oriented perfectionism (i.e., rigidly demanding perfection from one's partner); and (d) the relationships among variables did not differ based on gender. As the most rigorous test of the social disconnection model to date, this study provides strong support for this emerging model. Results also clarify the characterological and the interpersonal context within which depressive symptoms are likely to occur.

This study of university students (64 men and 99 women) examined both dispositional and situational influences of self-critical (SC) perfectionism on stress and coping, which explain its association with high negative affect and low positive affect. Participants completed questionnaires at the end of the day for 7 consecutive days. Structural equation modeling indicated that the relation between SC perfectionism and daily affect could be explained by several maladaptive tendencies associated with SC perfectionism (e.g., hassles, avoidant coping, low perceived social support). Multilevel modeling indicated that SC perfectionists were emotionally reactive to stressors that imply possible failure, loss of control, and criticism from others. As well, certain coping strategies (e.g., problem-focused coping) were ineffective for high-SC perfectionists relative to low-SC perfectionists.

Reports in the public media indicate that intense perfectionism and severe self-criticism played a role in the suicide of three remarkably talented individuals. The role of perfectionism in these suicides is consistent with recent extensive investigations of aspects of perfectionism as well as further analyses of the NIMH Treatment of Depression Collaborative Research Program (TDCRP), indicating that intense perfectionism interfered significantly with therapeutic response in the various brief treatments for depression. Self-critical individuals, however made substantial improvement in long-term intensive treatment. These findings suggest the value of considering psychopathology, especially depression, from a psychological rather than a symptomatic perspective; that different patients may be differentially responsive to various types of therapy, and that more extensive therapy may be necessary for many highly perfectionistic, self-critical patients.

Is self-critical perfectionism an antecedent of depressive symptoms, a consequence of depressive symptoms, or both? In the present study, self-critical perfectionism (i.e., harsh criticism of one's actions, negative reactions to perceived failures, and extreme concerns over others' evaluations) and depressive symptoms were conceptualised as a unified, interlocking syndrome wherein self-critical perfectionism and depressive symptoms reciprocally influence each other over time. This reciprocal relations model was tested in 240 undergraduates studied using a four-wave, 4-week longitudinal design. As hypothesised, reciprocal relations were observed between self-critical perfectionism and depressive symptoms, with self-critical perfectionism predicting changes in depressive symptoms and vice versa. Results suggest persons high in self-critical perfectionism may find themselves entangled in an escalating pattern where self-critical perfectionism both leads to, and results from, depressive symptoms. Research focused exclusively on unidirectional relations between self-critical perfectionism and depressive symptoms may ignore information critical to accurately understanding self-critical perfectionism, depressive symptoms, and their interrelation. Instead of assuming unidirectional relations between self-critical perfectionism and depressive symptoms, researchers are encouraged to test for reciprocal relations between these two variables.

This article attempted to demonstrate that the perfectionism construct is multidimensional, comprising both personal and social components, and that these components contribute to severe levels of psychopathology. We describe three dimensions of perfectionism: self-oriented perfectionism, other-oriented perfectionism, and socially prescribed perfectionism. Four studies confirm the multidimensionality of the construct and show that these dimensions can be assessed in a reliable and valid manner. Finally, a study with 77 psychiatric patients shows that self-oriented, other-oriented, and socially prescribed perfectionism relate differentially to indices of personality disorders and other psychological maladjustment. A multidimensional approach to the study of perfectionism is warranted, particularly in terms of the association between perfectionism and maladjustment.

Perfectionism is a major diagnostic criterion for one DSM-III diagnosis, and it has been hypothesized to play a major role in a wide variety of psychopathologies. Yet there is no precise definition of, and there is a paucity of research on, this construct. Based on what has been theorized about perfectionism, a multidimensional measure was developed and several hypotheses regarding the nature of perfectionism were tested in four separate studies. The major dimension of this measure was excessive concern over making mistakes. Five other dimensions were identified, including high personal standards, the perception of high parental expectations, the perception of high parental criticism, the doubting of the quality of one's actions, and a preference for order and organization. Perfectionism and certain of its subscales were correlated with a wide variety of psychopathological symptoms. There was also an association between perfectionism and procrastination. Several subscales of the Multidimensional Perfectionism Scale (MPS), personal standards and organization, were associated with positive achievement striving and work habits. The MPS was highly correlated with one of the existing measures of perfectionism. Two other existing measures were only moderately correlated with the MPS and with each other. Future studies of perfectionism should take into account the multidimensional nature of the construct.

Despite widespread agreement that multi-method assessments are optimal in personality research, the literature is dominated by a single method: self-reports. This pattern seems to be based, at least in part, on widely held preconceptions about the costs of non-self-report methods, such as informant methods. Researchers seem to believe that informant methods are: (a) time-consuming, (b) expensive, (c) ineffective (i.e., informants will not cooperate), and (d) particularly vulnerable to faking or invalid responses. This article evaluates the validity of these preconceptions in light of recent advances in Internet technology, and proposes some strategies for making informant methods more effective. Drawing on data from three separate studies, I demonstrate that, using these strategies, informant reports can be collected with minimal effort and few monetary costs. In addition, informants are generally very willing to cooperate (e.g., response rates of 76–95%) and provide valid data (in terms of strong consensus and self-other agreement). Informant reports represent a mostly untapped resource that researchers can use to improve the validity of personality assessments and to address new questions that cannot be examined with self-reports alone.

The psychometric properties of the Depression Anxiety Stress Scales (DASS) were evaluated in a normal sample of N = 717 who were also administered the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The DASS was shown to possess satisfactory psychometric properties, and the factor structure was substantiated both by exploratory and confirmatory factor analysis. In comparison to the BDI and BAI, the DASS scales showed greater separation in factor loadings. The DASS Anxiety scale correlated 0.81 with the BAI, and the DASS Depression scale correlated 0.74 with the BDI. Factor analyses suggested that the BDI differs from the DASS Depression scale primarily in that the BDI includes items such as weight loss, insomnia, somatic preoccupation and irritability, which fail to discriminate between depression and other affective states. The factor structure of the combined BDI and BAI items was virtually identical to that reported by Beck for a sample of diagnosed depressed and anxious patients, supporting the view that these clinical states are more severe expressions of the same states that may be discerned in normals. Implications of the results for the conceptualisation of depression, anxiety and tension/stress are considered, and the utility of the DASS scales in discriminating between these constructs is discussed.
