Using mobile phone technology to treat alcohol use disorder: study protocol for a randomized controlled trial

Area of Science:

• Digital health interventions
• Alcohol use disorder treatment
• Clinical trial methodology

Background:

• Healthcare systems face challenges in making alcohol use disorder (AUD) treatment accessible and appealing.
• Many individuals with AUD are reluctant to engage with existing treatment programs.
• This study protocol addresses the need for innovative approaches to AUD management.

Purpose of the Study:

• To evaluate the efficacy of mobile phone applications and breathalyzer devices in managing alcohol consumption.
• To assess the potential of technological tools in improving treatment engagement for alcohol-dependent individuals.
• To provide data on the effectiveness of digital health in reducing heavy drinking days.

Main Methods:

• A three-armed randomized controlled trial (RCT) involving 375 adults diagnosed with AUD.
• Participants will undergo a 3-month intervention with 3- and 6-month follow-ups.
• Primary outcome: reduction in heavy drinking days; Secondary outcomes: weekly alcohol consumption and blood alcohol levels.

Main Results:

• The study aims to quantify the impact of mobile technology and breathalyzers on reducing heavy drinking days.
• It will assess changes in weekly alcohol consumption and blood alcohol concentration.
• Data will be collected using Timeline Followback (TLFB) and Alcohol Use Disorder Identification Test (AUDIT) instruments, alongside phosphatidylethanol levels.

Conclusions:

• Improving data collection methods and treatment systems for AUD is crucial.
• Mobile phone technology and applications show promise for disease prevention and management.
• This research will offer insights into using technology for measuring and potentially decreasing alcohol consumption.
