Self-discrepancy theory (SDT) is a model of the relations between the self and affect which has been applied to the study of different types of psychopathology including depression, anxiety, and eating disorders. Although the theory itself is compatible with a transdiagnostic perspective on psychopathology, to date no systematic review of the literature has examined that possibility. We conducted a meta-analysis that synthesized the literature on self-discrepancy and psychopathology across a heterogeneous range of 70 studies. Results showed a small-to-medium association between self-discrepancy and psychopathology that was highly robust and similar in magnitude across domains. Furthermore, self-discrepancy was related to higher levels of a range of negative emotions and lower levels of a range of positive emotions. Meta-regression models showed that the effects were greater for actual:ideal discrepancy compared with actual:ought discrepancy for both depression and anxiety, which was contrary to the tenets of SDT which suggests specific associations between actual:ideal discrepancy and depression and actual:ought discrepancy and anxiety. Measurement type (i.e., idiographic vs. nomothetic) was a significant predictor of the effects for depression and anxiety, such that nomothetic measures evidenced greater associations compared with idiographic measures. Our findings could suggest that self-discrepancy represents a contributory factor related to a number of psychiatric disorders. However, the tenet of SDT suggesting unique associations between actual:ideal and actual:ought discrepancy and anxiety and depression respectively was not supported. Implications are discussed for future research on self-discrepancy and psychopathology including the study of mechanistic frameworks.

Objective Innovative treatments and outcome measures are needed for binge‐eating disorder (BED). This randomized controlled trial compared Integrative Cognitive‐Affective Therapy (ICAT‐BED), an individual psychotherapy targeting momentary behavioral and emotional precipitants of binge eating, with an established cognitive‐behavioral guided self‐help (CBTgsh) treatment using standard and ecological momentary assessment (EMA) outcome measures. Method A total of 112 participants were randomized to 17 weeks of treatment (21 sessions for ICAT‐BED and 10 sessions for CBTgsh). Binge‐eating frequency was assessed with the Eating Disorder Examination (EDE) as well as EMA using cell phone‐based real‐time, naturalistic assessment at end of treatment (EOT) and 6‐month follow‐up. Hypothesized maintenance mechanisms were assessed using self‐report questionnaires. Results Binge‐eating frequency as measured by the EDE and real‐time assessment showed significant reductions at EOT and follow‐up, with no significant differences between treatments. Hypothesized maintenance mechanisms, including emotion regulation, cognitive self‐discrepancy, self‐directed style, as well as measures of associated eating disorder psychopathology, depression, anxiety, impulsivity, and negative affect, showed similar improvement at EOT and follow‐up with no differences between treatments. Abstinence rates at EOT (ICAT‐BED: 57.1%; CBTgsh: 42.9%) and 6‐month follow‐up (ICAT‐BED: 46.4%; CBTgsh: 42.9%) were not significantly different. Treatment retention was significantly higher for ICAT‐BED (87.5%) than CBTgsh (71.4%). Discussion These findings suggest that ICAT‐BED and CBTgsh were associated with similar improvements in binge eating, psychopathology, and putative maintenance mechanisms as measured by traditional self‐report and momentary, naturalistic assessments and that these changes were generally sustained at 6‐month follow‐up.

Objective This study tested the association between food insecurity and eating disorder (ED) pathology, including probable ED diagnosis, among two cohorts of university students before and during the beginning of the COVID‐19 pandemic. Method Students (n = 579) from a large Midwestern American university completed self‐report questionnaires assessing frequency of ED behaviors, ED‐related impairment, and individual food insecurity as measured by the Eating Disorder Diagnostic Scale 5, Clinical Impairment Assessment, and Radimer/Cornell, respectively. Chi‐square tests and MANOVA with post‐hoc corrections were conducted to compare demographic characteristics, ED pathology, and probable ED diagnosis prevalence between students with and without individual food insecurity. Results Partially supporting hypotheses, MANOVA indicated significantly greater frequency of objective binge eating, compensatory fasting, and ED‐related impairment for students with food insecurity compared with individuals without food insecurity. Chi‐squared tests showed higher prevalence of ED diagnoses among individuals with food insecurity compared with those without food security (47.6 vs. 31.1%, respectively, p < .01, NNT = 6.06), specifically bulimia nervosa and other specified feeding and eating disorder. There were no differences in food insecurity before or during the beginning of the COVID‐19 pandemic. Discussion Consistent with prior literature, food insecurity was associated with elevated ED psychopathology in this sample. Findings emphasize the importance of proper ED screening for college students vulnerable to food insecurity and EDs.

Objective: There is ongoing discussion about whether sports participation is a risk or protective factor for eating disorders (EDs). Research is mixed, with some studies suggesting that athletes have higher mean levels of ED psychopathology compared to nonathletes, while other studies suggest the opposite effect or no differences. The purpose of the current meta-analysis was to identify whether female athletes reported higher mean levels of ED psychopathology compared to nonathletes.Method: Following PRISMA guidelines, we identified 56 studies that reported ED psychopathology for female athletes and nonathletes. A three-level random-effects model of between-and within-study variance was completed for the following outcome variables: overall ED psychopathology, body dissatisfaction, drive for thinness, restricting, and loss-of-control eating.Results: Athletes reported lower levels of body dissatisfaction compared to nonathletes (g = À.21, p < .0001). Athletes and nonathletes reported similar levels of overall ED psychopathology, drive for thinness, restricting, and loss-of-control eating on average. Sport type significantly moderated standardized mean difference effect sizes of ED psychopathology in athletes versus nonathletes. Effect sizes comparing levels of drive for thinness, restricting, and loss-of-control eating in athletes versus nonathletes were larger for studies with athletes participating in aesthetic/lean sports compared to nonaesthetic/nonlean sports.Discussion: Findings from this meta-analysis could inform future ED prevention and treatment in female athletes by providing further evidence that athletes in aesthetic/ lean sports may report higher levels of ED psychopathology. Participating in nonaesthetic/nonlean sports may be a protective factor for experiencing less body dissatisfaction.Public Significance Statement: The current meta-analysis summarized findings from 56 studies that assessed levels of disordered eating, body dissatisfaction, dietary restricting, and loss-of-control eating in female athletes and nonathletes. Athletes reported lower levels of body dissatisfaction compared to nonathletes, highlighting that participation in sport could have some protective factors.
