The Almost Perfect Scale-Revised (APS-R; Slaney, Rice, Mobley, Trippi, & Ashby, 2001) and the Child-Adolescent Perfectionism Scale (CAPS; Flett, Hewitt, Boucher, Davidson, & Munro, 1997) are two multidimensional scales assessing perfectionism. They were validated in children and adolescents samples. In order to meet the needs of French-speaking researchers, the present study exposes the validation study of their French versions. The sample consisted in 145 participants (72 girls) aged from 10 to 17 years. Results reveal a satisfactory internal consistency for both questionnaires. Further, medium to high correlations between overall scores and several sub-scores of both questionnaires show that they measure common dimensions of perfectionism. In addition, correlations between both scales and anxiety and depression show that only maladaptive perfectionism sub-scales are positively related to those symptoms. Finally, the results suggest taking into account school level and gender in the comparisons of the scores from the French version of the CAPS.
