The PBAT is an item pool for examining processes of psychological change. Its development paper presents it as a tool drawer from which items can be selected for a person and context, rather than a single diagnostic scale with one compulsory total score.

Instructions and scoring
Appendix A asks users to specify the time frame and context, such as the last week or a period at work. Respondents mark how much they agree with each statement based on that context.
Keep item-level meaning and the chosen assessment period clear. No universal total, clinical cutoff or missing-data procedure is supplied here. See the development paper and the main PBAT site for the intended analytic approach.
