There are few tools capable of measuring the personal recovery of individuals presenting with mental disorders that take into account the various dimensions of recovery. Personal recovery encompasses several objectives at the level of autonomy, positive interpersonal relationships, mental and physical health, self-acceptance, the school/professional domain, as well as developing a life project. A team of practitioners and researchers from four countries (Canada, Belgium, France, and Switzerland) adapted the Client Assessment of Strengths, Interests, and Goals (CASIG) tool to more accurately measure these different aspects of personal recovery. This study aims to validate the revised version of CASIG (CASIG-rev) in French, in terms of construct validity, test-retest reliability, convergent validity, and clinical sensitivity to change.

A total of 272 individuals were recruited across different French-speaking countries to respond to the CASIG-rev online, as well as Ryff's well-being measure, the Recovery Assessment Scale, and the WHODAS. A subgroup of 29 individuals responded again to the CASIG-rev after 1 month (for temporal stability), and 24 again at six months (for sensitivity to change).

The confirmatory factor analysis suggests a 5-factor model, very similar to the initially proposed model of 6 factors. Convergent validity was demonstrated between the subscales of tools measuring similar concepts, and test-retest reliability was proven for the majority of scales. The CASIG-rev also appears to be sensitive to clinical or rehabilitation changes, notably at the level of the life project.

This study supports the use of the CASIG-rev in French to measure the recovery of individuals presenting with mental disorders, as well as to support practitioners in the evaluation of their programs and interventions. Limitations, as well as the tool's relevance, are presented. An English validation is underway to make the CASIG-rev available in Anglo-Saxon countries.
