Psychometric Properties of the Dominic Interactive in a Sample of French Canadian Sexually Abused Children

Abstract

There are few computerized questionnaires assessing mental health in children. Although the psychometric properties of the Dominic Interactive have been verified for clinical and nonclinical populations, no study has specifically targeted sexually abused children. This study aimed to explore the reliability and validity of the Dominic Interactive with a sample of sexually abused children. The sample consisted of 687 children aged from 6 to 11 recruited in specialized intervention centers in Quebec. We conducted confirmatory factor analysis to assess the factorial structure of the questionnaire and assessed the internal consistency of the subscales with Cronbach alphas and McDonalds omegas. Subscales of the Dominic Interactive showed good fit with the factorial structure and met the prescribed criteria, except for Specific Phobias and Separation Anxiety subscales that showed high interitem correlations. After accounting for intercorrelation errors, all model fit indices showed good adjustment to the factorial structure and met the fit indices criteria. The different subscales of the DI were found to be significantly correlated ( r ranging from .13 to .30) with their equivalent parent-reported assessments. The results extend previous findings and suggest that the Dominic Interactive is a valid tool to quickly diagnose various behavioural problems in sexually abused children.
