Digital Intervention to Treat Anxiety and Depression Among Persons Receiving Treatment for Opioid Use Disorder

The study team will recruit a population of 60 adults who are receiving medication treatment for OUD from an online study based on Google Adwords, Reddit, and Facebook advertisements as online recruitment has been shown to be a viable and cost-effective recruitment method for opioid users. The total sample size may be expanded if recruitment costs are lower than expected. Participants will complete self-report assessments on their anxiety symptoms, depressive symptoms, opioid cravings, and opioid use behaviors. Participants will be randomized to a smartphone-based digital intervention or waitlist control condition. The digital intervention will be designed to treat participants' anxiety and depressive symptoms, and participants will be asked to use the intervention four times per week for four weeks (16 digital sessions).The smartphone intervention will also collect passive sensing data continuously during the 4 week period. Participants will complete post measures and one-month follow-up measures on anxiety symptoms, depressive symptoms, opioid cravings, and opioid use behaviors. The urine drug screen will be mailed to participants. Participants will also be asked to complete five urine tests to detect substance use (amphetamines, barbiturates, benzodiazepines, cocaine, ecstasy, marijuana, methamphetamine, opioids, oxycodone, and pcp) across the study (1 at pre-digital intervention, 1 during the digital intervention, 1 post-digital intervention, 1 between post and follow-up of the digital intervention, and 1 at the 1-month follow-up of the digital intervention). Participants will be instructed when to complete each urine test and will be asked to take a photo of the back the label of each test showing the results to the experimenters and to text these photos to a Google Voice Number maintained by the experimenters. Thus, this proposal seeks to address a crucial deficit in the availability of treatments for anxiety and depressive disorders among persons with OUD to ultimately augment treatment for OUD.
