Résumé

The aim of the present study was to evaluate some psychometric properties of the French-Canadian version of the Older Adult Self-Report (Achenbach et al., 2004), a self-reported measure of emotional, behavioral and interpersonal difficulties intended for people aged 60 years and older. This study examines some psychometric properties of the OASR, in terms of reliability (internal consistency) of the seven syndrome scales, and construct validity (structural, convergent and criterion validity). The instrument was completed by 321 older adults aged 60 years and older (M=68.36; SD=5.82) who were participating at the Université du troisième âge activities, which were taking place in two cities of the province of Quebec, Canada. Polychoric alpha coefficients varied between 0,72 and 0,93 and indicated a good internal consistency for the syndrome scales. Convergent validity was measured by multiple linear regression using life satisfaction as a dependent variable. A confirmatory factor analysis supported the seven-factor structure proposed in the original version of the instrument (CFI=.916, TLI=.914, RMSEA=.022 [.019, .025]). Results showed a good convergent validity, with 37.5% of variance explained by the problem scales. Overall, the results indicated that psychometric properties of the OASR meet expected standards for professional use of the French-Canadian version of the instrument.
