Implementation of transdiagnostic treatment for emotional disorders in residential eating disorder programs: A preliminary pre-post evaluation

摘要

Objective: Data are lacking from empirically supported therapies implemented in residential programs for eating disorders (EDs). Common elements treatments may be well-suited to address the complex implementation and treatment challenges that characterize these settings. This study assessed the preliminary effect of implementing a common elements therapy on clinician treatment delivery and patient (N = 616) symptom outcomes in two residential ED programs. Method: The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders was adapted to address ED and co-occurring psychopathology and implemented across sites. Therapists' treatment fidelity was rated independently to assess implementation success. Additionally, longitudinal (pre-post) design compared treatment outcomes among patients treated before and after implementation. Patient outcomes included ED and depressive symptoms, experiential avoidance, anxiety sensitivity, and mindfulness. Results: Following training and implementation, clinicians demonstrated adequate to good fidelity. Relative to pre-implementation, post-implementation patients showed significantly greater improvements in experiential avoidance, anxiety sensitivity, and mindfulness at discharge (ps <= .04) Relative to patients who were treated during the pre-implementation phase, patients in the post-implementation phase experienced more favorable outcomes on ED symptom severity, depression, mindfulness, and anxiety sensitivity at 6-month-follow-up (ps <= .001). A similar result was observed for experiential avoidance, yet this interaction effect was no longer statistically significant (p = .10) when the time x length of stay effect/covariate was added to the model. Conclusions: Preliminary pilot data support the feasibility of implementing transdiagnostic common elements therapy in residential ED treatment, and suggest that implementation may benefit transdiagnostic outcomes for patients.
