Digital Human-Based Brief Interventions for Harmful Alcohol Use: The PAHOLA Project

Alcoholism Clinical Trial

Official title: Digital Human-Based Brief Interventions for Harmful Alcohol Use: The PAHOLA Project

Status Not yet recruiting

Clinical Trial Summary

Alcohol use disorders are among the most prevalent mental disorders in Canada; however, due to numerous barriers, including fear of treatment, privacy concerns, stigma, time conflicts, and lack of availability of treatment, less than 10% of people with alcohol dependence receive treatment. Accordingly, there is a need to expand treatment coverage for alcohol use disorders, especially for populations which face barriers to receiving treatment. The objective of this proposed project is to develop a digital health worker, named PAHOLA, which can effectively deliver interventions to people who would not otherwise receive such treatment. To achieve this objective, the following research aims will be addressed: 1. To develop a digital human-based intervention that can initiate change processes and reduce alcohol use by applying the principles of motivational interviewing (MI) and cognitive behavioural therapy (CBT) in a credible manner. 2. To assess the impact of the virtual care provided by PAHOLA on health outcomes using a randomized controlled study design (RCT) to assess potential effect sizes for a larger future RCT. If successful, the PAHOLA project has the potential to transform our ability to prevent alcohol-attributable harms in Canada by promoting health, health equity, and well-being, especially among those people who do not normally receive treatment for harmful alcohol use.

Clinical Trial Description

Alcohol use disorders are among the most prevalent mental disorders in Canada; however, due to numerous barriers, including fear of treatment, privacy concerns, stigma, time conflicts, and lack of availability of treatment, less than 10% of people with alcohol dependence receive treatment. Accordingly, there is a need to expand treatment coverage for alcohol use disorders, especially for populations which face barriers to receiving treatment. . The objective of this proposed project is to tailor PAHOLA into a digital health worker which can effectively deliver BIs to people who would not otherwise receive such treatment. To achieve this objective, the following research aims will be addressed: 3. To develop a digital human-based intervention that can initiate change processes and reduce alcohol use by applying the principles of motivational interviewing (MI) and cognitive behavioural therapy (CBT) in a credible manner. 4. To assess the impact of the virtual care provided by PAHOLA on health outcomes using a randomized controlled study design (RCT) to assess potential effect sizes for a larger future RCT. To address these objectives, the study will employ the following research strategy This project will build upon the PAHOLA digital human prototype which was developed by Soul Machines, the Pan American Health Organization (PAHO), and Rooftop to provide information on alcohol risks and harms. This project will develop PAHOLA to intervene in cases of hazardous and harmful alcohol use, and will take place in the following three phases: Phase 1 - development of the intervention dialogue flow program. PAHOLA will (i) screen for harmful alcohol use using the AUDIT, and (ii) deliver Brief Intervention (BIs). The BIs will be based primarily on two evidence-based approaches that are used to effectively treat alcohol misuse, namely MI and CBT. Dialogue will be constructed in alignment with FRAMES - Feedback, Responsibility, Advice, Menu of options, Empathy, and Self efficacy (confidence for change),and OARS - (Open ended questions, Affirmation, Reflective listening, and Summarizing). Phase 2 - a two-day virtual meeting of researchers, health care providers, and people with lived experience. A virtual meeting of a total of 30 experts will be held to comment upon and further develop PAHOLA. Meeting participants will formulate a series of evidence-based recommendations regarding how to improve: 1) the affinity and trustworthiness of PAHOLA, 2) the dialogue flow for BIs, and 3) the specific dialogue flows for men and women. Phase 3 - a pilot randomized controlled trial (RCT) of the PAHOLA intervention program. To assess PAHOLA as a potential intervention for treating harmful alcohol use, a pilot RCT will be performed where the first group will receive a BI, the second group will receive a text-only version of PAHO's BI, and the third group will receive information from PAHOLA about the risks of alcohol use. A total of 180 adults (18 years of age and older) with hazardous and harmful alcohol use will be recruited via online advertisements and databases of individuals interested in participating in research studies. ;
