The purpose of this study is to access to the experiences of adolescents, their parents and healthcare professionals regarding psychotropic drugs in anorexia nervosa.

No preconceived ideas (according to qualitative methods) but a question: what are the participants' perceptions and experiences of psychotropic drugs in anorexia nervosa? In an adolescent medicine department.

Psychotropic prescription is common to adolescents suffering from anorexia nervosa. A first qualitative study (E3A Protocol "Experience of adolescents with anorexia nervosa toward antidepressants") looked at the experience of antidepressants among 15 adolescents suffering from anorexia nervosa. Analysis of the interviews identified two meta-themes:

1. Reactions to the proposal of antidepressant with an opposition phase (about the existence of depressive symptoms and about negative preconceptions) and need to share with family and other teenagers.
2. Reactions to antidepressant use with ambivalence and an initial perception of coercion, and effects of antidepressants (psychological effects, effects on the body and on anorexia nervosa and effects perceived through the eyes of others).

Nine adolescents (out of 15) were also taking an atypical antipsychotic (APA) often prescribed in case of anorexia nervosa resistance.

The need to share with family about the proposal of antidepressant and the effects perceived through the eyes of others (including parent's eyes) lead us to take an interest in parents perceptions.

Two decisive periods were identified: What do healthcare professionals think about psychotropic treatments for anorexia nervosa in adolescence? How do they propose treatment?

Interviewing teenagers, their parents as well as healthcare professionals, will enable to access to the complexity of representations and experiences of these psychotropic drugs in anorexia nervosa.
