Evaluation of Efficacy and Engagement of 'Hey Lemonade' App in Healthy Adults

INTERVENTION: This project will evaluate the efficacy and usability of a mobile app targeted at every day stress that delivers short tailored motivational or inspirational talks. The intervention period will last four weeks with participants randomized into one of the two research conditions. The Intervention Condition (N=60) will ‐ Use the Hey Lemonade app on an as‐needed basis to reflect real world use conditions. Participants will watch short motivational and inspirational talks. ‐Participants will watch short (2‐3 min) motivational/inspirational videos delivered by voice actors and public figures discussing strategies to cope with everyday stressors when they encounter them. They can access and watch these as needed – there is no prescribed dose. For the trial, participants will have access for the full 4 weeks. Use of the app will be monitored using app analytics and identified through participant codes. ‐Daily mood monitoring will be delivered by the Smartphone Ecological Momentary Assessment (SEMA) app and will take approximately 5 minutes per day. The app currently has 30‐40 uniquely written talks recorded by well‐known voice actors or public figures such as Zoe Terakes, Susie Youssef, Dylan Alcott, Chief Brabon and Tony Armstrong. CONDITION: Mental Health ‐ Studies of normal psychology, cognitive function and behaviour Well‐being ; ; Well‐being; PRIMARY OUTCOME: App engagement levels: number of interactions. Collected using app analytics.; [Continuous, over the 4 weeks of app usage.] App engagement levels: time per use. Collected using app analytics.[Continuous, over the 4 weeks of app usage.] Change in coping self‐efficacy as per the Coping self‐efficacy scale (26 items)[week 0 (pre‐intervention), week 4 (end of intervention)] INCLUSION CRITERIA: • Aged 25‐50 years old • Own device suitable for installation of Hey Lemonade and SEMA app • Residing in Australia SECONDARY OUTCOME: Affect status. Participants will be asked to provide momentary ratings of their affect at each assessment point using an existing 6‐item scale (Wilhelm and Schoebi 2007). [Continuous, over the 4 weeks of app usage. Participants will be reporting affect 2 times per day.] Daily hassles and uplifts. Collected using a shortened version of the Delongis scale.. The original scale includes 53 hassles, and uplifts experienced over the previous day. [week 0 (pre‐intervention), week 2 (mid‐intervention), week 4 (end of intervention)] Hassles. Hassles will be assessed via a self‐report measure of hassles derived from the Hassles Scale DeLongis, A., Folkman, S., & Lazarus, R. S. (1988).

This will be captured daily using a version of the above survey modified based on a pilot trial in a contemporary, Australia setting.] Perceived Stress Scale (14 items) [week 0 (pre‐intervention), week 4 (end of intervention)] Positive and Negative Affect Schedule (20 items) [week 0 (pre‐intervention), week 4 (end of intervention)] Primary outcome: App engagement levels: overall length of app interactions. Collected using app analytics.[Continuous, over 4 weeks of app usage.] Primary outcome: App evaluation: duration of engagement with video content. Recorded using in app analytics.[Continuous, over 4 weeks of app usage] Primary outcome: App evaluation: Page views for specific app components. Recorded using in app analytics. [Continuous, over 4 weeks of app usage.] Subjective wellbeing, Satisfaction with life scale (6 items). [week 0 (pre‐intervention), week 4 (end of intervention)] The user evaluation (subjective feedback) will be tailored toward specific pages. "How useful was this feature?” “how easy was this feature to use?” ; ; Participants will rate perceived usefulness on a Likert‐type scale out of 7 with lower scores representing lower perceived usefulness and ease of use.['Week 2 (2 weeks post‐commencement of intervention, intervention half way point)] The user evaluation (subjective feedback) will be tailored toward specific pages. “How likely would you recommend this to a friend” ; ; This will be asked on a 3 point fixed response with options yes, no, unsure.['Week 2 (2 weeks post‐commencement of intervention, intervention half way point)] Vitality, using Ryan and Frederick's Subjective Vitality Scale (7 items).
