Summary
This project will develop and pilot test a new smartphone-based system for AUD patients, their partners, and clinicians called PartnerCHESS. PartnerCHESS will integrate key features of ABCT and A-CHESS. PartnerCHESS will also include a Clinician Report to automatically alert clinicians of patients at risk of relapse and offer other information on how recovery is proceeding. The project has three specific aims:
1. Integrate A-CHESS with key features of ABCT to create PartnerCHESS to serve patients, partners, and clinicians.
2. Conduct a pilot test (a small randomized clinical trial) of PartnerCHESS to estimate effect size and refine the protocol, procedures, recruitment strategy, measurements, and operations for use in a large RCT.
3a. Decide whether to pursue an R01 application, and if so, 3b. plan for the R01.
