Predictors of treatment acceptance and of participation in a randomized controlled trial among women with anorexia nervosa.

Objective: This study aimed to identify predictors of acceptance of intensive treatment and of participation in a randomized controlled trial (RCT) among women with anorexia nervosa (AN).

Method: Participant data were drawn from a tertiary care intensive treatment programme including a previously published RCT. Women with AN (N = 106) were offered intensive treatment, and 69 were approached to participate in an RCT of olanzapine's efficacy as an adjunctive treatment for AN.
