Intervening on Opioid Use and Loneliness

Individuals (n = 300) with an opioid use disorder reporting loneliness will be randomized to either (1) therapist-delivered cognitive-behavioral therapy for perceived social isolation, (2) therapist-delivered Health Education, or (3) self-guided Health Education. Loneliness, opioid and other substance use, the amount of social interactions, social support, and mental and physical health factors prior to starting the treatment, after completing the treatment, and 1, 3, and 6 months following the treatment will be assessed to see how well they work compared to each other.
