Psychometric properties of the French translation of the Behavioral Activation for Depression Scale-Short Form (BADS-SF) in non-clinical adults

摘要

A decrease in the level of engagement in activities ("behavioral activation") is usually observed in major depressive disorder. Because behavioral treatments of depression aim to counteract that mechanism, assessing changes in behavioral activation during treatment is of great interest. Therefore, Manos et al. (2011) developed a scale that assesses these changes, which was called the Behavioral Activation for Depression Scale Short Form (BADS-SF). The aim of this study is to present a French version of this scale and to discuss its psychometric properties. The BADS-SF was translated into French, and 504 non-clinical adults completed an online survey that was composed of that scale and convergent measures. Exploratory and confirmatory factor analyses were performed in two independent samples, and a two-factor solution was recommended, which references two functions of the engagement in activities (i.e., "activation" and "avoidance"). The results showed high levels of internal consistency and satisfying scores in terms of skewness and kurtosis. Moreover, relationships with measures of depression and behavioral systems indicated a good convergent validity. Therefore, the French BADS-SF can be seen as a reliable and valid instrument.
