Abstract
OBJECTIVE: The goal of this study was to validate the French version of the Quality of Life in Bipolar Disorder (QoL.BD) scale, a condition-specific measure for bipolar disorder (BD). METHOD: The QoL.BD scale was translated into French in accordance with the recommendations for transcultural adaptation. It was administered to 125 participants with BD living in Quebec, Canada. Construct validity was evaluated through correlations with other measures of self-reported quality of life (QoL), functioning, and symptoms. Factorial structure was examined through an exploratory factor analysis. RESULTS: Internal reliability and test-retest reliability standards were met. Correlations in expected directions with other QoL, functioning, and depressive symptom scales supported convergent validity. The item loadings structure of the French QoL.BD largely replicated the original English version, with some modifications. CONCLUSION: The French version of the QoL.BD (full and brief) is comparable in its psychometric properties to the English version. It is a valid and sound measure for the evaluation of the QoL of French-speaking patients with BD.
