Outcome Measures

Primary Outcomes (3)

  • Change in Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) From Baseline to Post-treatment at 8 Weeks

    The AUDIT-C is a widely used 3-item self-report screen for hazardous or harmful alcohol consumption that is based off of the 10-item original AUDIT. The AUDIT-C is scored on a scale of 0-12 (scores of 0 reflect no alcohol use). In men, a score of 4 or more is considered positive; in women, a score of 3 or more is considered positive. Generally, the higher the AUDIT-C score, the more likely it is that the patient's drinking is affecting his/her health and safety.

    Change from Baseline to Post-treatment at 8 weeks

  • Change in The Drug Abuse Screening Test 10 (DAST-10) From Baseline to Post-treatment at 8 Weeks

    The DAST-10 is a brief, 10-item self-report assesses consequences related to drug abuse, excluding alcohol and tobacco. The range is 0-10, where higher scores indicate greater severity.

    Change from Baseline to Post-treatment at 8 weeks

  • Change in Number of Days Substance Use From Baseline to Post-treatment at 8 Weeks

    The number of days a substance was used the past 30 days

    Change from Baseline and Post-treatment at 8 weeks

Secondary Outcomes (8)

  • The Client Satisfaction Questionnaire (CSQ-8) at Post-treatment at 8 Weeks

    Post-treatment at 8 weeks

  • Usage Rating Profile Intervention (URPI) - Acceptability at Post-treatment at 8 Weeks

    Post-treatment at 8 weeks

  • Usage Rating Profile Intervention (URPI) - Feasibility at Post-treatment at 8 Weeks

    Post-treatment at 8 weeks

  • Change From Working Alliance Inventory (WAI-SR) From Mid-treatment at 4 Weeks to Post-treatment at 8 Weeks

    Change from Mid-treatment at 4 weeks to Post-treatment at 8 weeks

  • Change Patient Health Questionnaire (PHQ-8) From Baseline to Post-Treatment at 8 Weeks

    Change from Baseline to Post-Treatment at 8 weeks

  • +3 more secondary outcomes

Interventions

Woebot-SUDs (W-SUDS), an artificially intelligence-powered conversational agent on a smartphone app, eliminates most current SUDs treatment barriers while simultaneously leveraging technology to enhance user experience and engagement. W-SUDs expands and refines existing SUDs treatments by adapting skills from cognitive behavioral therapy, motivational interviewing, and dialectical behavior therapy.
