Clinical Trial Summary

This study will explore the feasibility, acceptability, and preliminary effectiveness of a smart phone delivered form of cognitive training intervention (Approach Bias Modification (ABM)) in a non-clinical community sample of middle to older adults (>55 years) reporting hazardous alcohol use in a pilot randomised controlled trial (RCT). This app is called AAT-APP+

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.

Related Conditions & MeSH terms

• Alcohol Use Disorder
• Alcoholism

Intervention

Behavioral:
• AAT-APP: A novel smart-phone approach-avoidance bias modification intervention
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.
• Sham training control
Complete an AAT on a weekly basis for four weeks

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Task acceptability as measured by the Mobile Application Rating Scale - user version (uMARS)	Acceptability of the SWIPE app, as measured by the user version of the Mobile Application Rating Scale (uMARS). Participants will respond on a scale of 1-5, whereby higher scores indicate greater acceptability	4-weeks
Other	Task feasibility	Feasibility of SWIPE app, as measured by recruitment and completion rates of at least 100 older adults within 6-months of advertising, with 50% of participants completing at least four sessions	4-weeks
Primary	Change in number of standard drinks past week	Change from baseline in number of standard drinks at 4-weeks	Change from baseline standard drinks at 4-weeks
Secondary	Change in number of drinking days past week	Change from baseline in number of drinking days at 4-weeks	Change from baseline drinking days at 4-weeks
Secondary	Change in number of standard drinks consumed in the past week throughout the 4-week training program	Change from baseline in number of standard drinks at the end of each week of training (i.e. week 1, week 2, week 3)	Change from baseline standard drinks consumed in the week prior to training compared to each week of training (i.e. week 1, week 2, week 3).
Secondary	Change in number of drinking days past week throughout the 4-week training program	Change from baseline in the number of drinking days at the end of each week of training (i.e. week 1, week 2, week 3)	Change from baseline number of drinking days in the week prior to training compared to each week of training (i.e. week 1, week 2, week 3).
Secondary	Change in number of drinking days at follow up	Change from baseline in the number of drinking days at 8-weeks	Change from baseline number of drinking days at 8-weeks
Secondary	Craving Frequency Score (as measured by the Craving Experience Questionnaire, Frequency)	Change from baseline craving, as measured by the Craving Experience Questionnaire, at 4-weeks. The Craving Experience Questionnaire - frequency consists of an 11-point visual analogue scale, anchored 0 = not at all, to 10 = extremely/constantly, assessing craving frequency, whereby higher scores are suggestive of greater craving frequency	Change from baseline craving frequency at 4-weeks
Secondary	Craving Frequency Score (as measured by the Craving Experience Questionnaire, Frequency, Follow up)	Change from baseline craving, as measured by the Craving Experience Questionnaire, at 8-weeks. The Craving Experience Questionnaire - frequency consists of an 11-point visual analogue scale, anchored 0 = not at all, to 10 = extremely/constantly, assessing craving frequency, whereby higher scores are suggestive of greater craving frequency	Change from baseline craving frequency at 8-weeks
Secondary	Approach-avoidance behaviours (alcohol approach avoidance questionnaire)	Change from baseline in self-report of approach and avoidance towards alcohol, as measured by the alcohol approach avoidance questionnaire, at 4-weeks. This is a 20-item self report measure with two primary dimensions of alcohol craving (i.e. approach and avoidance), where higher scores are suggestive of greater approach or avoidance behaviours (rated on a 9-point scale, 0 = not at all, 8 = very strongly).	Change from baseline approach-avoidance behaviours at 4-weeks
Secondary	Approach-avoidance behaviours (alcohol approach avoidance questionnaire) at follow up	Change from baseline in self-report of approach and avoidance towards alcohol, as measured by the alcohol approach avoidance questionnaire, at 8-weeks. This is a 20-item self report measure with two primary dimensions of alcohol craving (i.e. approach and avoidance), where higher scores are suggestive of greater approach or avoidance behaviours (rated on a 9-point scale, 0 = not at all, 8 = very strongly).	Change from baseline approach-avoidance behaviours at 8-weeks
Secondary	Approach-avoidance behaviours (approach avoidance task)	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).
