High rates of relapses are common in eating disorder patients after achieving the status
of remission. The lack of support after completing a treatment can contribute to relapse.
Therefore aftercare programs are needed to maintain the benefits of treatment, to reduce
the risk of relapse, and to stabilize patients’ well-being. This paper describes the Internetbased
aftercare program ACTUA (Continued Support for Eating Disorders) developed to support
patients with bulimia nervosa in Mexico. ACTUA is an adaptation of the program EDINA (Internetbased
maintenance treatment for eating disorders) which was developed and evaluated in
Hungary. In this paper we first describe the intervention which consists of different modules
including a monitoring and feedback tool, forums, and counseling chat with a clinician. In the
second part, we report on first experiences following the introduction of the program in two
treatment centers in Mexico (Monterrey and Mexico City). Fifteen patients participated in a
semi-structured interview assessing perceived benefits of participating in ACTUA as well as barriers
that prevented patients from joining the program. Implications for the implementation of
Internet-based interventions in Mexico are discussed.
