The mobile health system used in this study, called Thrive4Life Connect, has been developed for use in harm reduction settings with prior funding from the National Institute on Drug Abuse. Thrive4Life Connect is based on the Addiction Comprehensive Health Enhancement Support System (A-CHESS) and facilitates brief, behavioral interventions targeting knowledge gaps, motivation, and social connectedness. This app is being used in another study at University of Wisconsin-Madison (registered to NCT04268173).~The proposed study will develop new intervention content for assessing and increasing vaccine confidence and lowering overdose risk. The feasibility and preliminary effectiveness will be tested using a pilot, pre-post study design with 60 people who have injected drugs in the past week and used opioids in the past 30 days. The investigators will examine feasibility outcomes based on study recruitment, retention, and intervention completion. Changes in knowledge about COVID-19 and overdose, motivation to reduce risk, and behavioral outcomes including overdose risk behaviors and vaccine uptake will be examined to establish preliminary effectiveness.
This study will examine if the use of a smartphone application called Thrive4Life Connect can help people who use drugs lower their risk of overdose and learn more about COVID-19 vaccines. 60 participants will be enrolled and can expect to be on study for up to 6 months.
