A process approach to verbal memory assessment: Exploratory evidence of inefficient learning in women remitted from anorexia nervosa.

Introduction: Anorexia nervosa (AN) is associated with deficits in set-shifting and cognitive flexibility, yet less is known about the persistence of these deficits after recovery and how they might contribute to reported difficulties organizing and learning new information. To address this question, the current study applied a process-focused approach, that accounts for errors and strategies by which a score is achieved, to investigate the relationship between verbal memory and executive function in women remitted from AN. Method: Twenty-six women remitted from anorexia nervosa (RAN) and 25 control women (CW) aged 19-45 completed the California Verbal Learning Test, Second edition (CVLT-II) and the Wisconsin Card Sorting Test (WCST). Groups were compared on overall achievement scores, and on repetition, intrusion, and perseverative errors on both tests. Associations between learning and memory performance and WCST errors were also examined. Results: RAN and CW groups did not differ on overall CVLT-II learning and memory performance or errors on the WCST, though the RAN group trended towards greater WCST non-perseverative and total errors. On the CVLT-II, the RAN group made significantly more repetition errors than CW (p = 0.010), and within-trial perseveration (WTP) errors (p = 0.044). For the CW group, CVLT-II learning and memory performance were negatively associated with errors on the WCST, whereas among RAN, primarily delayed memory was negatively correlated with WCST errors. Notably, for RAN, greater WCST perseverative responses were correlated with greater CVLT-II repetition and WTP errors, showing the convergence of perseverative responding across tasks. Conclusions: Despite similar overall learning and memory performance, difficulties with executive control seem to persist even after symptom remission in patients with AN. Results indicate an inefficient learning process in the cognitive phenotype of AN and support the use of process approaches to refine neuropsychological assessment of AN by accounting for strategy use.

Psychometric Evaluation and Norms for the Multidimensional Assessment of Interoceptive Awareness (MAIA) in a Clinical Eating Disorders Sample.

Altered interoceptive awareness (IA) has been implicated in the pathophysiology of eating disorders; however, few comprehensive self-report measures of IA exist in eating disorders. The present study sought to validate the Multidimensional Assessment of Interoceptive Awareness (MAIA), originally developed to assess IA in individuals practicing mind-body therapies, in an eating disorder sample. Adult and adolescent patients (n = 376) completed assessments upon admission to a partial hospital programme. Analyses examined the factor structure of the MAIA, scale means, scale-scale correlations, internal consistency and construct validity. Analyses also examined associations between MAIA subscales and eating disorder symptoms. Results supported the original eight-factor structure of the MAIA. Internal consistency was acceptable, and the scales converged with associated measures. Importantly, Not Distracting, Self-regulation, Body Listening and Trusting were most strongly associated with eating disorder symptoms. Results support use of the MAIA among eating disorders and provide further support for the relevance of IA in eating disorders.

Short-term intensive family therapy for adolescent eating disorders: 30-month outcome.

Family therapy approaches have generated impressive empirical evidence in the treatment of adolescent eating disorders (EDs). However, the paucity of specialist treatment providers limits treatment uptake; therefore, our group developed the intensive family therapy (IFT)-a 5-day treatment based on the principles of family-based therapy for EDs. We retrospectively examined the long-term efficacy of IFT in both single-family (S-IFT) and multi-family (M-IFT) settings evaluating 74 eating disordered adolescents who underwent IFT at the University of California, San Diego, between 2006 and 2013. Full remission was defined as normal weight (≥ 95% of expected for sex, age, and height), Eating Disorder Examination Questionnaire (EDE-Q) global score within 1 SD of norms, and absence of binge-purging behaviours. Partial remission was defined as weight ≥ 85% of expected or ≥ 95% but with elevated EDE-Q global score and presence of binge-purging symptoms (<1/week). Over a mean follow-up period of 30 months, 87.8% of participants achieved either full (60.8%) or partial remission (27%), while 12.2% reported a poor outcome, with both S-IFT and M-IFT showing comparable outcomes. Short-term, intensive treatments may be cost-effective and clinically useful where access to regular specialist treatment is limited.
