To explore mental health associations during eating disorder (ED) treatment. Based on the dual-continua model of mental health, general and ED-specific psychopathology, as well as emotional, psychological, and social well-being were considered as mental health domains. Network analyses with panel data were applied to explore within- (temporal and contemporaneous networks) and between-person effects in a sample of 1250 female ED patients during 12 months of outpatient treatment.

Objectives: Applying machine-learning methodology to clinical data could present a promising avenue for predicting outcomes in patients receiving treatment for psychiatric disorders. However, preserving privacy when working with patient data remains a critical concern.

Methods: In showcasing how machine-learning can be used to build a clinically relevant prediction model on clinical data, we apply two commonly used machine-learning algorithms (Random Forest and least absolute shrinkage and selection operator) to routine outcome monitoring data collected from 593 patients with eating disorders to predict absence of reliable improvement 12 months after entering outpatient treatment.

Article Synopsis
  • - The study analyzed how eating disorder (ED) patients respond to treatment over a year, using data from 442 individuals at five different time points and focusing on ED psychopathology and well-being.
  • - Three distinct classes of ED psychopathology were identified: one group had high initial severity with slow recovery (55.9%), another had high severity followed by significant recovery (19.9%), and the last had moderate severity with no significant recovery (24.2%).
  • - For well-being, the classes included one with low initial levels and slow growth (44.6%), another with low initial levels and substantial growth (9.5%), and a stable moderate class (45.9%), highlighting the variability in change trajectories that could

Eating Disorders (EDs) are serious psychiatric disorders, impacting physical and psychosocial functioning, often with a chronic course and high mortality rates. The two continua model of mental health states that mental health is a complete state, that is, not merely the absence of mental illness, but also the presence of mental health. This model was studied among ED patients by examining the presence and correlates of well-being and psychopathology.

Background: Outcome studies for eating disorders regularly measure pathology change or remission as the only outcome. Researchers, patients and recovered individuals highlight the importance of using additional criteria for measuring eating disorder recovery. There is no clear consensus on which additional criteria are most fundamental.

In the eating disorder (ED) field there is a lack of guidelines regarding the utilization of recovered therapists and the experiential knowledge they can bring to therapy. In this study, a qualitative design was used to examine recovered eating disorder therapists using their experiential knowledge and how this influences therapy and the patients they treat. Respectively, 205 patients (response rate 57%), and 26 recovered therapists (response rate 75%) completed a questionnaire about advantages and disadvantages of the utilization of experiential knowledge in therapy.
