We considered having the same therapists deliver both treatments to limit therapist-specific effects independent of the actual treatment condition. Upon further consideration, we decided that this approach could potentially lead to overlap in the delivery of the two treatments and/or unintentional biases in the implementation of the control treatment. Therefore, we decided to have a total of four therapists of similar experience. Two will deliver the IM therapy, and other two will provide NT. The therapists for both groups will have similar qualifications. To prevent bias, the therapists of NT will be blinded to the study hypotheses. Treatment fidelity will be monitored through sample audio records of selected sessions to ensure the separation of treatment protocols. If diffusion occurs, further training will be utilized. To further prevent bias, none of the therapists will be involved in outcome assessment, and they will be blind to participant responses. Assessment measures will be conducted by research staff available for the study.
