For those patients in the intervention conditions, during each session the clinician used CBT and motivational enhancement strategies to engage the patient in treatment and enhance retention. The CBT intervention was composed of a shortened version of the original CBT intervention, comprised of modules that focus on identifying and correcting negative distortions or cognitions, promote behavioral activation through engaging the patient in pleasant activities, and develop supportive relationships. All sessions were tailored within the structured format considering the patient's needs and always employed a collaborative approach with the patient.
