The Feasibility of Utilizing the Open Dynamic Interaction Network (ODIN) app to assess rEMA data across 30 days among those Recovering from Alcoholism

About ~4 million people with an alcohol use disorder receive treatment annually, and frequent relapse has produced a rapid revolving door between recovery and use. This paper presents preliminary data from a prospective micro-longitudinal study (30 days) that examines co-evolution of relapse risk processes of people with alcohol use disorders who entered a short-term residential substance use treatment. The primary goal of the current data was to assess the feasibility of using the open dynamic interaction network (ODIN) responsive ecological momentary assessment (rEMA). rEMA collected daily estimates on affect, urges, sober-support engagement, and use. The ODIN app administered twelve questions at established EMA times each day. GPS identified engagement in sober support activities and alcohol cue exposure (e.g., gas stations, grocery stores, bars) prompted additional questions. Of the eight hundred questions asked over 31 days, the mode for questions answered was 500. Five-day estimates showed that 80% of the participants answered between 80-100 questions (10-30 questions/day). Also, the ODIN app acquired 95% of GPS readings across 30 days (~288 GPS readings/day). Most were satisfied with stability (84%), look/feel (82.4%), and ease of use (92.2%) of the ODIN app. Participants also reported interest in longer assessments (100%) using the app if it prompted them to call sponsor (85%) or to use relapse prevention skills (72%). Preliminary findings show that the ODIN platform accurately and efficiently collects data amongst this population. There was a high rate of acceptability, satisfaction, and interest in using ODIN to help them engage in sober support/relapse prevention.
