Are perfectionism dimensions risk factors for bulimic symptoms? A meta-analysis of longitudinal studies

A multi-country examination of the relationship between perfectionism and disordered eating: the indirect effect of obsessive beliefs and obsessive-compulsive symptoms

BACKGROUND

Despite the extensive literature on the association between perfectionism and disordered eating (DE), only scant attention has been given to the underlying processes that may mediate this relationship. The present study aimed to contribute to existing literature by investigating the direct and indirect relations between perfectionism and DE through obsessive-compulsive disorder (OCD) symptoms and obsessive beliefs, among community adults from three different countries and cultural backgrounds (i.e. Poland, Italy and Lebanon).

METHODS

This is a cross-sectional study that was carried-out among 977 community adults (77.1% females, mean age: 21.94 ± 3.14 years) using the snowball sampling technique.

RESULTS

Obsessive-compulsive disorders (OCD) symptoms and obsessive beliefs had a partial indirect effect in the relationship between multidimensional perfectionism and disordered eating. Higher multidimensional perfectionism/obsessive beliefs were significantly associated with greater OCD symptoms and directly associated with higher DE scores. Finally, higher OCD symptoms were significantly linked to higher DE scores.

CONCLUSION

The preliminary results suggest that it would be helpful for clinicians to routinely include measures of perfectionism, OCD and obsessive beliefs when dealing with individuals who present DE problems. In addition, results hold promise for the combined use of perfectionism and OCD interventions as a potentially beneficial treatment option for DE concerns.

Perfectionistic Self-Presentation and Psychopathology: A Systematic Review and Meta-Analysis

Decades of research implicate perfectionism as a risk factor for psychopathology. Most research has focused on trait perfectionism (i.e., needing to be perfect), but there is a growing focus on perfectionistic self-presentation (PSP) (i.e., the need to seem perfect). The current article reports the results of a meta-analysis of previous research on the facets of PSP and psychopathology outcomes (either clinical diagnoses of psychiatric disorders or symptoms of these disorders). A systematic literature search retrieved 30 relevant studies (37 samples; N = 15,072), resulting in 192 individual effect-size indexes that were analysed with random-effect meta-analysis. Findings support the notion of PSP as a transdiagnostic factor by showing that PSP facets are associated with various forms of psychopathology, especially social anxiety, depression, vulnerable narcissism and-to lesser extent-grandiose narcissism and anorexia nervosa. The results indicated that there both commonalities across the three PSP and some unique findings highlighting the need to distinguish among appearing perfect, avoiding seeming imperfect and avoiding disclosures of imperfections. Additional analyses yielded little evidence in the results across studies including undergraduates, community samples and clinical samples. Our discussion includes a focus on factors and processes that contribute to the association between PSP and psychopathology.

Psychometric properties of an Arabic translation of the Big Three Perfectionism Scale-Short Form (BTPS-SF) in a community sample of adults

BACKGROUND

Despite the high clinical relevance of the perfectionism construct as a transdiagnostic contributor to different mental health symptoms, and the recent burgeoning of research in this area across cultures in the past two decades, the Arab region was one of the cultural settings experiencing the slowest progress in this line of research. This study aimed to make a meaningful contribution to the literature by validating an Arabic-language version of the 16-item Big Three Perfectionism Scale-Short Form (BTPS-SF). In particular, we sought to examine structure and concurrent validity, internal consistency, and measurement invariance across gender groups.

METHOD

A web-based, convenience sampling method was adopted to collect a sample of Arabic-speaking adults from the general population of Lebanon (N = 515; aged 27.55 ± 10.92 years; 69.9% females). The forward-backward method was applied in translating the Arabic version of the BTPS-SF.

RESULTS

The examination of the internal structure, using Confirmatory Factor Analysis (CFA), demonstrated that the three-factor model (i.e., rigid, self-critical, and narcissistic perfectionism) fitted well to the data. All three factors of the Arabic 16-item BTPS-SF yielded excellent reliability estimates, with both Cronbach's alpha and McDonald's omega ranging from 0.83 to 0.86. Multi-group CFA revealed that fit indices showed no significant difference in model fit at the configural, metric, and scalar levels, thus suggesting that the factor loadings, pattern structure, and item intercepts are invariant across gender groups. Finally, BTPS-SF subscales scores correlated positively with psychological distress (i.e., depression, stress and anxiety), and inversely with subjective well-being, indicating an acceptable concurrent validity.

CONCLUSION

The present findings allow us to conclude that the Arabic BTPS-SF permits to capture reliably and validly three main factors of perfectionism. We hope that providing this psychometrically sound scale will encourage its large use not only in empirical research, but also in clinical applications, including psychological screening and treatment monitoring.

The association between eating disorders and perfectionism in adults: A systematic review and meta-analysis

OBJECTIVE

Dimensions of perfectionism are associated with the onset and maintenance of eating disorder pathology in both clinical and non-clinical samples. The aim of this study was to conduct a systematic review and meta-analysis of the association between perfectionism and eating disorders in adults.

METHOD

A literature search was conducted using the PsycINFO, Medline, Scopus, Embase, Web of Science and ProQuest databases. Ninety-five studies met the inclusion criteria and included a total sample of 32,840 participants (clinical eating disorder diagnosis N = 2414, non-clinical N = 30,428). Correlation coefficients (r) for the association between eating disorders and perfectionism were pooled. A meta-analysis to determine the association between two dimensions of perfectionism and eating disorder symptoms was conducted. Subgroup analyses were conducted with studies using clinical samples, and studies using the Eating Disorder Examination Questionnaire.

RESULTS

The pooled effect size for the association between perfectionistic concerns and eating disorder symptoms was r = 0.33 [0.30, 0.37]; and r = 0.20 [0.14, 0.25] for the association between perfectionistic strivings and eating disorder symptoms. In the clinical subgroup analyses the effect sizes were r = 0.40 [0.22, 0.58]; and r = 0.35 [0.26, 0.44] respectively. Medium to high heterogeneity was identified across all subgroup analyses and a significant level of publication bias was also identified.

DISCUSSION

The findings indicate both perfectionistic strivings and perfectionistic concerns have significant associations with eating disorders, and further support the argument that both dimensions of perfectionism are important factors in the prevention and treatment of eating disorders.

Perfectionism and binge eating association: a systematic review and meta-analysis

BACKGROUND

Perfectionism is considered a vulnerability factor for eating disorders. However, the role of perfectionism in binge eating needs clarification due to notably inconsistencies between studies. The purpose to this study was to conduct a systematic review and meta-analysis to estimate the perfectionism-binge eating association.

METHOD

Systematic review was performed according to the PRISMA 2020 statement. Four databases (Web of Science, Scopus, PsycINFO and Psicodoc) were searched to identify studies published until September 2022. The literature search yielded 30 published articles (N = 9392) that provided 33 independent estimations of the correlation between the two variables.

RESULTS

Random-effects meta-analysis revealed a small-to-moderate positive average effect size between general perfectionism and binge eating (r₊ = .17) with a large heterogeneity. Perfectionistic Concerns showed a significant small-to-moderate relationship with binge eating (r₊ = .27), whereas Perfectionistic Strivings presented a negligible relationship with binge eating (r₊ = .07). Moderator analyses showed that the age, the type of the sample, the study design, and the tools for assessing both variables were statistically associated with the perfectionism-binge eating effect sizes.

CONCLUSIONS

Our findings suggest that Perfectionism Concerns are closely associated with binge eating symptomatology. This relationship might be moderated by certain variables, especially by the clinical or non-clinical nature of the sample and the instrument employed to assess binge eating.

Neurodevelopmental Model Explaining Associations between Sex Hormones, Personality, and Eating Pathology

Clinical scientists have been investigating the relationships between sex hormones, personality, and eating disorders for decades. However, there is a lack of direct research that addresses whether personality mediates or moderates the relationships between sex hormones and eating pathology. Moreover, the neural mechanisms that underlie the interactive associations between these variables remain unclear. This review aims to summarize the associations between these constructs, describe a neural mechanism mediating these relationships, and offer clinical strategies for the early identification and intervention of eating disorders. The gathered evidence shows that aggressiveness, impulsivity, and obsessive-compulsiveness may mediate or moderate the relationships between sex hormones and eating pathology, but only among females. Furthermore, sex hormone receptor density in the mesocorticolimbic dopamine pathway may explain the neural mechanism of these associations. Future research should use more comprehensive personality measurements and assess the mediation and moderation effects of temperament while taking the hormone levels of women across menstrual cycles into account. Additionally, electroencephalography and functional magnetic resonance imaging should be implemented to directly assess brain activity and corroborate these findings.

Identifying transdiagnostically relevant risk and protective factors for internalizing psychopathology: An umbrella review of longitudinal meta-analyses

Internalizing mental disorders are highly comorbid with one another, and evidence suggests that etiological processes contributing to these disorders often overlap. This systematic umbrella review aimed to synthesize meta-analytic evidence from observational longitudinal studies to provide a comprehensive overview of potentially modifiable risk and protective factors across the depressive, anxiety, and eating disorder psychopathology domains. Six databases were searched from inception to August 2022. Only meta-analyses of longitudinal studies that accounted for baseline psychopathology (either via exclusion of baseline cases or statistical adjustment for baseline symptoms) were included. Methodological quality of meta-analyses was evaluated using the AMSTAR 2, and quality of evidence for each analysis was rated using GRADE. Study selection, quality assessment, and data extraction were conducted in duplicate by independent reviewers. The protocol for this review was registered with PROSPERO (CRD42020185575). Sixty-one meta-analyses were included, corresponding to 137 meta-analytic estimates for unique risk/protective factor-psychopathology relationships. Most potential risk/protective factors, however, were examined only in relation to depressive psychopathology. Concern over mistakes and self-esteem were the only risk and protective factors, respectively, identified as statistically significant across depressive, anxiety, and eating disorder psychopathology domains. Eight risk factors and four protective factors also emerged as having transdiagnostic relevance across depressive and anxiety domains. Results suggest intervention targets that may be valuable for preventing/treating the spectrum of internalizing psychopathology and reducing comorbidity. However, few factors were identified as transdiagnostically relevant across all three internalizing domains, highlighting the need for more research investigating similar sets of potential risk/protective factors across internalizing domains.

Examining the relationship of eating disorder symptoms and perfectionism in men and women using two assessments of eating pathology

Eating disorder (ED) pathology in men is not as well understood or studied as ED pathology in women. One potential reason for this is that most of the traditional assessments used for EDs were developed for and validated with exclusively female samples, meaning that symptoms in men are not as well represented or measured. There are consistent associations between perfectionism and ED symptoms in women, but less is known regarding how these relationships function in men. This study examined whether the relationship of perfectionism to ED symptoms varies by gender using the Eating Disorder Examination-Questionnaire (EDE-Q) and the Eating Pathology Symptom Inventory (EPSI). The EPSI has multiple dimensions that may better capture the presentation of ED symptoms in men. Participants were recruited from a large public university and through Amazon MechanicalTurk. Participants completed a survey battery that included the two eating measures and the self-oriented perfectionism scale from the Hewitt and Flett Multidimensional Perfectionism Scale. Data were analyzed using independent samples t-tests and structural equation modeling. There were significant positive associations between self-oriented perfectionism and all dimensions measured by the EDE-Q and the EPSI. The models were invariant across gender. Implications for further research were discussed.

Mediating Mechanisms of Perfectionism: Clinical Comorbidity of OCD and ED

Obsessive-compulsive disorder (OCD) and eating disorders (ED) share common causal factors and often represent similar entities. Studies on obsessive-compulsive disorders and eating disorders reveal a significant correlation between maladaptive perfectionism. The objective of this study is to evaluate the predictive variables of perfectionism in patients diagnosed with Anorexia Nervosa (AN), Bulimia Nervosa (BN) and OCD using a structural equation model (SEM). The sample consisted of 187 participants (60.9% women, 39.1% men) with a mean age of 26.68 (SD = 10.97). The findings reveal that the model is the same in all the disorders evaluated, achieving an adequate fit: χ2 = 7.95 (p = 0.000), RMSEA = 0.087 (95% confidence interval: 0.00 to 0.02), CFI = 0.991, TLI = 0.951 and with an overall predictive capacity of around 30% (CD = 0.318). It is recommended that future studies address the subtypes of disorders evaluated using longitudinal designs.

Is perfectionism a killer of creative thinking? A test of the model of excellencism and perfectionism

The standards that a person pursue in life can be set in a rigid or flexible way. The recent literature has emphasized a distinction between high and realistic standards of excellence, from high and unrealistic standards of perfection. In two studies, we investigated the role of striving towards excellence (i.e., excellencism) and striving towards perfection (i.e., perfectionism) in relation to divergent thinking, associative thinking, and openness to experience, general self-efficacy, and creative self-beliefs. In Study 1, 279 university students completed three divergent thinking items, which called for creative uses of two common objects and to name original things which make noise. A measure of openness to experience was included. Results from multiple regression indicated that participants pursuing excellence tended to generate more answers and more original ones compared with those pursuing perfection. Openness to experience was positively associated to excellencism and negatively associated to perfectionism. In Study 2 (n = 401 university students), we replicated these findings and extended them to associative tasks requiring participants to generate chains of unrelated words. Additional individual differences measures included general self-efficacy, creative self-efficacy, and creative personal identity. The results suggested that excellencism was associated with better performance on divergent thinking and associative tasks, compared with perfectionism. Excellencism was positively associated with all four personality variables, whereas perfectionism was significantly and negatively associated with openness to experience only. Implications for the distinction between perfectionism and excellencism with respect to creative indicators are discussed. In addition, the paradoxical finding that perfection strivers had high creative self-efficacy and creative personal identity but lower openness to experience and poorer performance on objective indicators of creative abilities is discussed.

Longitudinal relations of self-criticism with disordered eating behaviors and nonsuicidal self-injury

OBJECTIVE

Self-criticism has been proposed as a transdiagnostic predictor of disordered eating and nonsuicidal self-injury (NSSI). First, this study explored cross-sectional associations of multiple disordered eating behaviors, NSSI, and self-criticism. Second, it tested longitudinal relations of self-criticism with disordered eating and NSSI, adjusting for baseline levels of both behaviors.

METHODS

In Sub-study 1, undergraduates (N = 251, 79.5% female, M_age = 19.1 years) completed self-report measures of disordered eating, NSSI, and self-criticism at baseline and after 8 weeks. In Sub-study 2, community-based young adults with histories of disordered eating, NSSI, or both (N = 517, 88.8% female, M_age = 24.7 years) completed measures of disordered eating, NSSI, and self-criticism at baseline and after 4 weeks. All measures were completed online.

RESULTS

In Sub-study 1, both disordered eating and NSSI showed significant cross-sectional associations with self-criticism, and self-criticism was significantly related to binge eating, fasting, and NSSI at follow-up. In Sub-study 2, both behaviors again showed significant cross-sectional associations with self-criticism. Self-criticism showed significant longitudinal relations with fasting, purging, and excessive exercise. Longitudinal relations of self-criticism with NSSI varied across disordered eating behaviors.

DISCUSSION

NSSI showed cross-sectional associations with a range of disordered eating behaviors. Self-criticism reflects a common correlate of both disordered eating and NSSI. Evidence supported transdiagnostic longitudinal impact of self-criticism across multiple forms of disordered eating but provided more limited support for impacts on NSSI.

Non-Suicidal Self-Injury and Eating Disordered Behaviors: An Update on What We Do and Do Not Know

PURPOSE OF REVIEW

The current report aims to summarize recent advances about the relationship between non-suicidal self-injury (NSSI) and eating disordered (ED) behaviors and highlights meaningful directions for future research.

RECENT FINDINGS

While there is solid evidence indicating a robust cross-sectional association between NSSI and ED behaviors, emerging evidence suggests that the temporal relationship between these behaviors may be bidirectional. Shared functions and risk factors may explain why these behaviors often co-develop. At the same time, little is still known about the psychosocial consequences of comorbid NSSI and ED engagement, and there is a lack of intervention studies that target these behaviors simultaneously. It is well-established that NSSI and ED behaviors frequently co-occur. The field should now turn to longitudinal designs to advance our understanding of the longer-term developmental and the shorter-term momentary relationship of these behaviors in daily life. Providing insight into these areas will help guide the deployment of evidence-based interventions that match the needs of clients who report comorbid NSSI and ED behaviors.

Reflections on Three Decades of Research on Multidimensional Perfectionism: An Introduction to the Special Issue on Further Advances in the Assessment of Perfectionism

In this article, we introduce this second special issue on the assessment of perfectionism along with an overview of developments in the perfectionism field over the past 30 years following the shift to studying perfectionism as a multidimensional construct. We examine some key contributions over the past decade, including the proliferation of meta-analyses and apparent rise over time in the prevalence of self-oriented, other-oriented, and socially prescribed perfectionism. We also outline what we consider to be seven definitive truths about the perfectionism construct and how these themes are reflected in the articles that follow. This special issue includes papers that describe abbreviated measures of existing perfectionism scales as well as new measures. Other papers in this special issue demonstrate the need to supplement a trait approach with a focus on cognitive perfectionism and to evaluate key mediators of the association between perfectionism and depression. Other research illustrates the usefulness of supplementing the predominant variable-focused approach with a person-centered approach. Collectively, the papers address several significant issues and outline key directions for future research in the next decade of research on multidimensional perfectionism.
