Paranjothy SM, Wade TD. A meta-analysis of disordered eating and its association with self-criticism and self-compassion. Int J Eat Disord 2024; 57:473-536. [PMID: 38366726 DOI: 10.1002/eat.24166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 01/23/2024] [Accepted: 01/27/2024] [Indexed: 02/18/2024]
Abstract
OBJECTIVE Future treatments for eating disorders (ED) need to be enhanced by targeting maintaining mechanisms. Literature suggests self-criticism and self-critical perfectionism act as key mechanisms exacerbating ED, and self-compassion protects against self-criticism. This meta-analysis examines associations between self-criticism and self-critical perfectionism on disordered eating (DE), and reviews how self-compassion and self-criticism relate to each other with respect to DE. METHOD Searches across three databases yielded 135 studies across 42,952 participants. Heterogeneity, publication bias, and quality assessments were analyzed. Moderation analyses between self-criticism measures, self-compassion measures, between clinical and nonclinical samples, and between cross-sectional and experimental studies were also conducted. RESULTS Random-effects models showed a medium positive link between self-criticism and DE (r = .37), and 10 subgroups pertaining to various measures of self-criticism utilized in literature showed small to large positive links with DE (r = .20-.52). Preliminary evidence also suggests negative relationships between self-compassion and DE (r = -.40 to -.43) and negative relationships between self-compassion and self-criticism (r = -.04 to -.88). DISCUSSION Greater levels of self-criticism is linked with greater levels of DE and reduced levels of self-compassion, suggesting a need to tackle self-criticism and nurture self-compassion in standard treatments for ED. Understanding these interactions better in conjunction with dismantling intervention studies can help develop more effective and efficient interventions targeting self-criticism and self-compassion for people with DE. PUBLIC SIGNIFICANCE STATEMENT Higher levels of self-criticism are linked with higher levels of DE and lower self-compassion. Self-compassion interventions could be more effective and efficient in reducing ED symptoms if self-criticism is tackled early in such treatments.

Mental Health Variables Impact Weight Loss, Especially in Patients with Obesity and Binge Eating: A Mediation Model on the Role of Eating Disorder Pathology. Nutrients 2023; 15:3915. [PMID: 37764699 PMCID: PMC10537364 DOI: 10.3390/nu15183915] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 09/05/2023] [Accepted: 09/06/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Various mental health and eating behavior variables have been independently associated with predicting weight loss in individuals with obesity. This study aims to investigate a mediation model that assesses the distinct contributions of these variables in predicting weight changes in patients with obesity following an outpatient behavioral weight loss intervention (BWLI). METHODS General mental health (depression, anxiety, stress, impulsivity), eating behavior (cognitive restraint, disinhibition, hunger), eating disorder pathology, and body mass index (BMI) were assessed in a group of 297 patients with obesity at the admission of a BWLI program. BMI was re-evaluated during the final treatment session. A mediation model was employed to examine whether mental health and eating behavior variables predicted BMI changes, with eating disorder pathology serving as a mediator. The model was tested both overall and within two patient subgroups: those with regular binge eating (≥four episodes/month) and those without. RESULTS In the overall sample (n = 238), the relationships between depression, impulsivity, and cognitive restraint with BMI change were mediated by eating disorder pathology. In the subgroup with regular binge eating (n = 99, 41.6%), the associations between stress and disinhibition with BMI change were additionally mediated by eating disorder pathology. In the subgroup without regular binge eating, eating disorder pathology showed no mediating effect. DISCUSSION Multiple mental health and eating behavior variables assessed at admission predicted BMI changes, particularly when mediated by eating disorder pathology in patients with regular binge eating. A comprehensive psychopathological assessment prior to starting BWLI may help identify multiple factors affecting prognosis and treatment outcomes. Long-term follow-up studies in this field are required.

Abstract
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.
