Single-session behavioral activation for alcohol use disorder: a randomized controlled pilot trial

Area of Science:

• Psychology
• Psychiatry
• Behavioral Science

Background:

• Brief psychotherapy for alcohol use disorder (AUD) often focuses on motivation rather than behavioral change.
• Behavioral activation (BA) is an action-oriented therapy that reinforces value-based, substance-free activities, potentially addressing this gap.

Purpose of the Study:

• To examine the preliminary efficacy of a single-session ultrabrief behavioral activation (UBA) intervention for individuals with mild-moderate AUD.
• To assess the impact of UBA on alcohol consumption and related psychological factors.

Main Methods:

• A randomized controlled parallel-group pilot trial was conducted with 40 participants.
• Participants were assigned to either the UBA intervention group or an assessment-only control group.
• Alcohol use was assessed at baseline and up to 3-month follow-up.

Main Results:

• Both UBA and control groups showed reductions in drinking frequency, drinks per drinking day, and average alcohol consumption.
• The most significant difference was observed in percent drinking days at the 2-week follow-up (d = -0.53, p = 0.064).
• The UBA group experienced increases in behavioral activation, value-consistency, and a decrease in anhedonia.

Conclusions:

• The UBA intervention shows potential as a therapeutic tool for alcohol use disorder.
• UBA may help bridge the gap between brief motivational interventions and longer psychotherapy courses for AUD.
• Further investigation into UBA is warranted for its efficacy in managing AUD.
