This report describes the development of the fidelity rating tools for the Building Recovery by Improving Goals, Habits, and Thoughts (BRIGHT) and BRIGHT-2 interventions — cognitive behavioral therapy interventions for clients with co-occurring depression and substance use problems. The tools, which assess adherence to and competence in administering the BRIGHT treatments, and their interrater reliability are discussed, and a recommended training plan for fidelity coders in research settings is presented. The training plan includes coder selection, initial training, and ongoing training. Finally, specific guidance is provided on how to apply the fidelity tools. This guidance is based on experience using the tools within a research context, but it should be helpful for supervisors in clinical settings as well.
