[Introduction of an evaluation strategy in the psychosocial rehabilitation of psychiatrically handicapped adults in Belgium: an approach matching programs to the needs of beneficiaries].

This article examines the implementation of an evaluation strategy in a socio-professional rehabilitation centre. In this project, measuring instruments were developed with the double intention of providing a clinical evaluation that would be useful for the intervener, as well as ensuring an evaluation of the clientele's evolution that would assist in the observation of effects resulting from interventions within groups of beneficiaries. Following the first analysis of data, which showed that the program had difficulty in retaining its clientele, a second study was undertaken to establish the profile of beneficiaries on whom the program had a positive impact and those for whom the stay at the centre did not provide any significant effects.
