Targeting habits in anorexia nervosa: a proof-of-concept randomized trial.
BACKGROUND Habits are behavioral routines that are automatic and frequent , relatively independent of any desired outcome , and have potent antecedent cues . Among individuals with anorexia nervosa ( AN ) , behaviors that promote the starved state appear habitual , and this is the foundation of a recent neurobiological model of AN . In this proof-of-concept study , we tested the habit model of AN by examining the impact of an intervention focused on antecedent cues for eating disorder routines . METHODS The primary intervention target was habit strength ; we also measured clinical impact via eating disorder psychopathology and actual eating . Twenty-two hospitalized patients with AN were r and omly assigned to 12 sessions of either Supportive Psychotherapy or a behavioral intervention aim ed at cues for maladaptive behavioral routines , Regulating Emotions and Changing Habits ( REaCH ) . RESULTS Covarying for baseline , REaCH was associated with a significantly lower Self-Report Habit Index ( SRHI ) score and significantly lower Eating Disorder Examination- Question naire ( EDE-Q ) global score at the end-of-treatment . The end-of-treatment effect size for SRHI was d = 1.28 , for EDE-Q was d = 0.81 , and for caloric intake was d = 1.16 . CONCLUSIONS REaCH changed habit strength of maladaptive routines more than an active control therapy , and targeting habit strength yielded improvement in clinical ly meaningful measures . These findings support a habit-based model of AN , and suggest habit strength as a mechanism-based target for intervention
