Behavioral Activation for Depression - Short Form (BADS-SF)
The questionnaire is designed to measure changes in avoidance and activation over the course of Behavioral Activation for depression. The Behavioral Activation for Depression Scale (BADS) can be used to track changes weekly in the behaviors hypothesized to underlie depression and specifically targeted for change by behavioral activation. It examines changes in the following areas: activation, avoidance/rumination, work/school impairment, and social impairment. The BADS-SF consists of nine questions, each rated on a seven point scale ranging from 0 (not at all) to 6 (completely).
To score the BADS, items from all scales other than the Activation scale are reverse-coded and then all items are summed. To score the subscales, no items are reverse-coded. This process allows high scores on the total scale and the subscales to be represented by the scale and subscale names. In other words, for the total scale, higher scores represent increased activation, while for the Social Impairment subscale, higher scores represent increased social impairment.
