Cognitive-behavioral therapy for avoidant/restrictive food intake disorder: A proof-of-concept for mechanisms of change and target engagement.

ABSTRACT:

Background

Cognitive-behavioral therapy for avoidant/restrictive food intake disorder (ARFID; CBT-AR) theoretically targets three prototypic motivations (sensory sensitivity, lack of interest/low appetite, fear of aversive consequences), aligned with three modularized interventions. As an exploratory investigation, we: (1) evaluated change in candidate mechanisms in relationship to change in ARFID severity, and (2) tested if assignment (vs. not) to a module resulted in larger improvements in the corresponding mechanism.

Method

Males and females (N = 42; 10-55 years) participated in an open trial of CBT-AR.

Results

Decreases in scaled scores for each candidate mechanism had medium to large correlations with decreases in ARFID severity-sensory sensitivity: -0.7 decrease
