Adaptation of the behavioral activation for depression scale (BADS) in cancer patients

Abstract

Objective: To adapt the Behavioral Activation for Depression Scale (BADS) and submit it to confirmatory factor analysis in an oncological patients sample. Method: Instrumental study in two phases, phase 1 followed the American Psychological Association standards to translate and adapt the original scale (BADS) to Spanish (n=101), in phase 2 we applied the scale obtained in the previous phase and submitted it to confirmatory factor analysis (n= 341). Results: the confirmatory factorial analysis showed a scale consisting of four factors and 12 items, with a fit: X2= 1.24 gl= 48 p= .118; CFI= .98, TLI= .98, RMSEA= .27, NFI= .93, RFI= .91, IFI= .98, PNFI= .68; had a medium negative correlation with anxiety and depression constructs. Conclusions: The adaptation of the Behavioral Activation Scale for Depression aimed at cancer patients has acceptable psychometric properties, which allows have an adequate instrument to measure the level of behavioral activation in this population.
