Family members of patients with schizophrenia, especially when they assume caregivers' positions, experience difficulties to adapt to the situation. To gain insight into these caregivers' coping style is a challenge to decrease the stress of family members, and in this way, improve patient related outcome. The FCQ (Family Coping Questionnaire) is an adapted clinical assessment tool that focuses on specific ways to cope with dysfunction that characterize the psychotic pathology. The goal of this study was to provide validity evidence about the French version of the FCQ. Swiss and French family members of individuals suffering from schizophrenia (n = 204) responded to the FCQ. A confirmatory factor analysis (CFA) was applied estimating two models. The seven-factor model showed adequate fit to the data while the three-factor model fit was poor. This FCQ internal validation showed an adequate model fit with a French population including various family members (parents, siblings, etc.) of persons with enduring mental illness.
