A Phase 2 interventional study of W-SUDs and Digitally-delivered Psychoeducation in Alcohol Use Disorder (AUD) and Substance Use Disorders, sponsored by Woebot Health. Completed at 1 site in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2024-10-24.
Sponsored by Woebot Health · Phase 2, Interventional, and Treatment
This study aims to validate W-SUDs as a digitally-delivered substance use disorder program through a fully-powered randomized control trial that will test the comparative efficacy of the mobile-app based substance use disorder program (W-SUDs) to reduce substance use relative to a psychoeducation control condition, which has no cognitive behavioral therapy and the content is not delivered through a conversational user interface.
Phase II will evaluate the efficacy of W-SUDs in a large scale RCT relative to a psychoeducation control condition. Primary outcomes will be measures of the quantity and frequency of substance use including number of substance use occasions, heavy drinking days (if applicable) and percent reduction in substance use occasions. Additionally, Phase II will evaluate whether W-SUDs results in a greater reduction in substance-related problems compared to a psychoeducation control group and explore if engagement with W-SUDs, relative to psychoeducation control,

Exclusion Criteria:
Woebot (W-SUDs), a Conversational Agent (CA) instantaneously available 24 hours per day, 7 days per week, 'checks in' with users. Using conversational tones, it encourages mood tracking and delivers general psychoeducation as well as tailored empathy, cognitive behavior therapy (CBT)-based behavior change tools, and behavioral pattern insight. Woebot's app-based platform and user-centered design philosophy makes it an optimal modality for Substance Use Disorders (SUD) treatment delivery. It offers immediate, evidence-based tailored support in the patient's peak moment of craving.
Device: W-SUDs
Psychoeducation delivers weekly fact sheets that include information on: 1. Alcohol-specific topics; 2. Drug-specific topics; 3. General addiction topics; 4. Statistics relating to alcohol and substance use.
Other: Digitally-delivered Psychoeducation
Woebot (W-SUDs) is an automated conversational agent, available through a smartphone application, that delivers evidence-based psychotherapeutics, empathy, and emotional health psychoeducation.
A form of psychoeducation for those seeking treatment for their alcohol and/or substance use concern. Psychoeducation is commonly provided for those with substance use. Psychoeducation in substance use is intended to increase the users' knowledge of their substances of use, and effects on the body, behaviors, and consequences. The recipient of psychoeducation is expected to increase their own awareness of their substance use and ideally incorporate this newfound knowledge when making changes to their substance use. The information provided in this group are from factsheets found on NIAAA, NIDA, and CDC web pages.
