Objectives: To examine the psychometric properties of the Dominic Interactive (DI) in school-aged children in a different cultural environment than Quebec. Methods: In a large French region, 100 schools and 25 children (aged 6 to 11 years) per school were randomly selected. Data were collected using self-administered questionnaires to children (DI), parents (sociodemographic characteristics, mental health services use), and teachers (child school achievement). DI psychometric properties were assessed by examining: the distribution of each DI diagnosis; comorbidity between diagnoses; alpha cœfficients measuring internal consistency; and correlates of psychopathologies with sociodemographic status and health care services use. Estimates of DI properties were compared with those from a sample of community children in Quebec. Results: Complete data were available for 1274 children (54.4%). The internal consistency of each DI diagnosis of the French version was reasonable, with Cronbach's alpha cœfficients ranging from 0.62 to 0.89. The psychometric properties and comorbidity were consistent with the version from Quebec. Conclusions: The satisfactory psychometric properties of the DI along with other demonstrated advantages of this instrument (children enjoy the activity, parents approve of it, and it is cost-effective) and its cultural adaptability support the consideration of the DI for epidemiologic studies in diverse cultures.
