Family-focused vs. Drinker-focused Smartphone Interventions to Reduce Drinking-related Consequences of COVID-19

Overview

This R01 project titled "Family-focused vs. Drinker-focused Smartphone Interventions to Reduce Drinking-related Consequences of COVID-19" is a Hybrid II RCT/implementation study to modify and test two of our alcohol smartphone interventions to address the fallout from COVID. We propose a three-arm RCT comparing a smartphone control group vs. a drinker-focused intervention vs. a family-focused intervention. All study arms recruit dyads comprising a person who drinks and a family partner.

The current randomized controlled trial tested whether PartnerCHESS (an ACHESS intervention along with aspects of Alcohol Behavioral Couple Therapy designed specifically for individuals with alcohol use disorder and their concerned significant other) could reduce high-risk drinking and improve quality of life. For this trial, 199 dyads (398 participants) were recruited from the community and randomized 1:1:1 to the PartnerCHESS intervention, ACHESS intervention, or smartphone control for 8 months with a follow-up at 12 months. Participants were part of a dyad: identified patients met criteria for high-risk drinking (defined by the DSM-5) and had at least one drink in the past month, concerned significant others were the identified patient's romantic partner, family member, or close friend aged 21 or older. Primary outcomes were identified patient percent high-risk drinking days, and quality of life for both identified patients and concerned significant others. Participants were surveyed at baseline, 4, 8, and 12 months; PartnerCHESS and ACHESS usage data were continuously collected. We found significant difference in both PartnerCHESS and ACHESS arms compared to smartphone control in percent high-risk drinking days as well as identified patient quality of life. Additionally, PartnerCHESS had significantly lower percent high-risk drinking days than ACHESS at 12 months, suggesting a stronger long-term impact. We also found significantly less distress among ACHESS concerned significant others as compared to those in PartnerCHESS and the smartphone control arms.
