AAT-APP+: A Novel Brain-training App to Reduce Drinking
AAT-APP+: A Pilot RCT of a Novel Smart-phone App to Reduce Alcohol Consumption Among Middle to Older Adults in the Eastern Health Community
Study Overview
Status
Conditions
Detailed Description
Alcohol use in older adults is of particular concern, with the 55-74 year old cohort most likely to exceed lifetime alcohol risk. Approach Bias Modification (ABM) is a form of computerised cognitive training that is an efficacious intervention for alcohol use disorder. Previous studies are limited in that the stimuli are not personalised, nor are interventions readily accessible to non-treatment seeking problem drinkers. This has led to the development of a world-first, smart phone version of ABM called AAT-APP+
The current study aims to explore the feasibility, acceptability, and preliminary effectiveness of AAT-APP+ in reducing alcohol consumption and cravings in a pilot RCT with a non-clinical community sample of 100 older adults (aged 55+ years) reporting hazardous alcohol use (i.e. a score of 8+ on the AUDIT), recruited via targeted advertising. Participants in active training will upload (or select pre-selected) photos of beverages and meaningful activities, which will form the 'avoid' and 'approach' stimuli, respectively, then complete two training sessions per week for four weeks, with results compared to controls. AAT-APP+ holds promise as an innovate, cost-effective, and remotely accessible adjunctive support tool.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Experimental: Approach Bias Modification
Participants will complete 2 x 5-7 min training sessions of approach bias modification for the period of four weeks
|
Participants allocated to the intervention group will be required to upload photos of drinks they wish to avoid, as well as activities they wish to engage in more, and be trained to avoid and approach by repeatedly 'swiping' images away from and towards themselves, respectively.
|
ACTIVE_COMPARATOR: Control: Minimal intervention
Participants will complete a standardised alcohol approach-avoidance training task (AAT) on a weekly basis for four weeks.
|
Complete an AAT on a weekly basis for four weeks

Time Frame: Change in alcohol approach/avoidance from baseline at 4-weeks
|
Change in alcohol approach/avoidance behaviours from baseline at 4-weeks, as calculated by([reaction time for pushing alcohol stimuli] - [reaction time for pulling alcohol related stimuli]) - ([reaction time for pushing neutral objects] - [reaction time for pulling neutral objects]).
Higher positive values indicate a tendency to approach alcohol faster (i.e.
faster reaction times for pulling as opposed to pushing), whereas negative values indicate a tendency to avoid alcohol (i.e.
slower reactions times for pulling compared to pushing alcohol).
