Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The main objective of the study is to evaluate the feasibility of utilizing digital health technology with opioid use disorder (OUD) patients as measured by a 12-week period of continuous assessment using smartphone surveys and digital sensing. In addition, we will examine the utility of 3 types of digital data (Ecological Momentary Assessment (EMA); Digital sensing; and social media data) in predicting OUD treatment retention and buprenorphine medication adherence.
