To conduct a pre-pilot study with 20 POD patients to a) evaluate the acceptability and potential efficacy of specific sessions (i.e., reduced illicit opioid use as assessed by urine toxicology and self-report findings, and decreased pain as evidenced by attenuated pain intensity and pain interference on self-report measures from baseline throughout treatment) for inclusion in integrated Cognitive Behavioral Therapy (CBT) for POD and the sequence of sessions, b) assess patients' satisfaction with integrated CBT as evidenced by qualitative feedback from individual exit interviews, and c) develop and modify initial therapist training and process rating measures. Products will include a) a manual for integrated CBT for POD to be used in opioid treatment programs and primary care settings with POD patients, b) therapist training materials, and c) process rating instruments.
