“…In the future, latent variable models could be supplemented with network and other machine learning approaches to further elucidate the associations between variables of interest, without subscribing to causal interpretations (39,68). Regardless, we believe a demonstration of the robustness of latent variable models to contribute to theory-building and offer input for network variable selectionto arrive at better descriptions of psychopathology in line with the principle of epistemic iteration (69)(70)(71).…”

BackgroundEating disorder (ED) subtyping studies have often extracted an undercontrolled, an overcontrolled and a resilient profile based on trait impulsivity and perfectionism. However, the extent to which methodological choices impact the coherence and distinctness of resulting subtypes remains unclear.ObjectiveIn this paper, we aimed to assess the robustness of these findings by extracting personality-based subtypes on a sample of ED patients (N = 221) under different analytic conditions.MethodsWe ran four latent profile analyses (LPA), varying the extent to which we constrained variances and covariances during model parametrization. We then performed a comparative analysis also including state ED symptom measures as indicators. Finally, we used cross-method validation via k-means clustering to further assess the robustness of our profiles.ResultsOur results demonstrated a four-profile model based on variances in impulsivity and perfectionism to fit the data well. Across model solutions, the profiles with the most and least state and trait disturbances were replicated most stably, while more nuanced variations in trait variables resulted in less consistent profiles. Inclusion of ED symptoms as indicator variables increased subtype differentiation and similarity across profiles. Validation cluster analyses aligned most with more restrictive LPA models.ConclusionThese results suggest that ED subtypes track true constructs, since subtypes emerged method-independently. We found analytic methods to constrain the theoretical and practical conclusions that can be drawn. This underscores the importance of objective-driven analytic design and highlights its relevance in applying research findings in clinical practice.

ObjectiveFuture 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.MethodSearches 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.ResultsRandom‐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).DiscussionGreater 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 StatementHigher 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.

ObjectivePrevious studies have highlighted the relevance of perfectionism, self‐esteem, and anxio‐depressive symptoms in anorexia nervosa (AN). However, the relationships between these factors and cardinal eating disorders (ED) symptoms remain unclear, particularly in AN subtypes. This study aimed to examine their interconnections using network analysis.MethodThe sample included n = 338 inpatients with AN who completed the Eating Disorder Examination Questionnaire, Frost Multidimensional Perfectionism Scale, Rosenberg Self‐Esteem Scale, and Hospital Anxiety and Depression Scale. Using network analysis, we estimated three networks: full sample, AN‐restrictive (AN‐R) and AN‐binge/purging (AN‐BP) subtypes. We estimated central and bridge symptoms using expected influence and conducted an exploratory network comparison test to compare AN subtypes.ResultsOvervaluation of Weight and Shape, Concern over Mistakes, and Personal Standards were consistently central in all networks. The most central bridge symptoms across all networks were Concern over Mistakes and Self‐Esteem. Concern over Mistakes bridged perfectionism and ED symptoms, while Self‐Esteem was highly connected to all symptom clusters. Anxiety was significantly more central in the AN‐R network compared to the AN‐BP network.ConclusionsThe present study contributes to a growing body of network studies suggesting that nodes related to perfectionism are just as central as cardinal ED symptoms, indicating the relevance of perfectionism in ED pathology. The high bridge centrality of self‐esteem suggests that it may be an important link between perfectionism, mood, and ED symptoms. Future research should investigate the efficacy of targeting multiple psychological factors in the treatment of AN, as well as their potential transdiagnostic relevance.
