Objective: Previous 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.Method: The 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.Results: Overvaluation 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.Conclusions: The 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.

Objective: Research regarding the therapeutic application of psychedelics and psychedelic‐assisted psychotherapy in the treatment of eating disorders (EDs) has begun to emerge. This systematic scoping review aimed to map and synthesise the existing evidence regarding the participant reported efficacy and perspectives concerning psychedelics in the treatment of EDs, and to identify significant research gaps.Method: A systematic search was undertaken across several databases in accordance with Preferred Reporting Items for Systematic reviews and Meta‐Analyses extension for Scoping Reviews guidelines.Results: 1290 publications were identified, 1135 after duplicates removed, with 17 meeting full‐eligibility criteria. Overall, findings suggested that most participants reported experiencing a meaningful reduction in their ED symptoms and having positive experiences or an openness to explore psychedelics as a treatment for ED symptoms, although some noted concerns of adverse effects and the importance of having psychological support to increase safety and efficacy.Conclusions: While preliminary research suggests psychedelics and psychedelic‐assisted psychotherapy may be a viable treatment option for ED symptoms, further research with more robust research designs is required to increase confidence in its efficacy, generalisability, and safety as a therapeutic medium.

The cognitive-interpersonal model of anorexia nervosa (AN) posits that cognitive and interpersonal traits contribute to the development and maintenance of AN. We investigated cognitive and interpersonal factors put forward by the model in a sample of 145 adolescent inpatients with AN using network analysis. Our main outcomes included core eating disorder symptoms, cognitive style, socio-affective factors, and mood symptoms. We estimated a cross-sectional network using graphical LASSO. Core and bridge symptoms were identified using strength centrality. Goldbricker was used to reduce topological overlap. The node with the highest strength centrality was Concern over Mistakes, followed by Eating Preoccupation, Social Fear, and Overvaluation of Weight and Shape. The nodes with the highest bridge strength were Concern over Mistakes, Doubt about Actions, Overvaluation of Weight and Shape, and Depression. Notably, both performance on a cognitive flexibility task and BMI were not connected to any other nodes and were subsequently removed from the final network. We provide partial support for the cognitive-interpersonal model while also supporting certain premises put forward by the transdiagnostic cognitive-behavioral model. The high centrality of Concern over Mistakes and Social Fear supports the theory that both cognitive and interpersonal difficulties contribute to AN, particularly in adolescence.

Substance use disorders (SUD) in mothers of young children can negatively impact the family unit and promote the intergenerational cycle of mental health disorders. This systematic review aims to: 1) provide an overview of substance use treatments for mothers of young children (from birth to 5 years old); 2) synthesize findings on maternal substance use and child/maternal mental health outcomes; and 3) identify key treatment components. Database searches in Medline, PsycINFO, PubMED, and PsycARTICLES were conducted on May 7th, 2024. A total of 14, 916 articles were identified following duplicate removal. Articles were screened following PRISMA guidelines. Eight articles (n = 900) met inclusion criteria. Outcomes of interest included maternal substance use, child/maternal mental health, and treatment components. All studies indicated maternal substance use treatments were at least as, or more, effective in improving maternal substance use and child/maternal mental health outcomes compared to controls. Treatment components included: mother/family mental health, basic needs, parenting skills, occupation/education, operant conditioning, crisis management, and medical education. Operant conditioning was the only treatment component which appeared to positively impact maternal substance use outcomes; no other treatment components were associated with outcomes of interest. This review provides preliminary evidence highlighting the benefits of substance use treatments for mothers of young children on substance use and mental health outcomes. Future randomized controlled trials with harmonized outcome measures and qualitative data that identifies treatment needs of mothers with lived experience are crucial to evaluate maternal substance use treatments and improve treatment development.
