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.

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 randomly assigned to 12 sessions of either Supportive Psychotherapy or a behavioral intervention aimed at cues for maladaptive behavioral routines, Regulating Emotions and Changing Habits (REaCH).

Covarying for baseline, REaCH was associated with a significantly lower Self-Report Habit Index (SRHI) score and significantly lower Eating Disorder Examination-Questionnaire (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.

REaCH changed habit strength of maladaptive routines more than an active control therapy, and targeting habit strength yielded improvement in clinically meaningful measures. These findings support a habit-based model of AN, and suggest habit strength as a mechanism-based target for intervention.

Several population studies on beliefs about depression carried out in western countries during the 1990s have shown that the public clearly favors psychotherapy over antidepressant medication. The present study examines whether this phenomenon still exists at the end of the first decade of the twenty-first century.

In 2009, a telephone survey was conducted among the population of Vienna aged 16 years and older (n = 1205). A fully structured interview was administered which began with the presentation of a vignette depicting a case of depression fulfilling the diagnostic criteria of DSM-IV for a moderate depressive episode.

Psychotherapists were most frequently endorsed as source of professional help. Antidepressant medication still was more frequently advised against than recommended. Respondents familiar with the treatment of depression tended to be more ready to recommend to seek help from mental health professionals and to endorse various treatment options, particularly medication.

At the end of the first decade of this century, there still exists a large gap between the public's beliefs and what mental health professionals consider appropriate for the treatment of depression. Therefore, further effort to improve the public's mental health literacy seems necessary.
