Description of intervention(s) / exposure
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.

Summary
Brief summary
Background: The Hey Lemonade mobile app is in the development phase having attained initial seed investment to make the MVP (minimum viable product). The objective of the app is to tackle smaller mental health issues before they become bigger through the on demand delivery of situation-specific pep or motivational talks. The app contains a series of 2–3-minute talks designed to circuit break and help people alleviate common everyday stress. The content of the talks have been developed by the Hey Lemonade team in collaboration with professional writers and two clinical psychologists. The app developers have also drawn on design, user experience and user interface research to identify the most effective means of delivering the app content. 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.
Aims / Objectives:
While commercial mobile apps designed to promote health and well-being are becoming more and more popular, few are subject to rigorous testing to support the benefits they claim to deliver. The current project aims to quantify how engagement with the Hey Lemonade mobile app effects mood and stress in a real world setting as well as evaluate user experience. To do this the research team are proposing an uncontrolled two-arm randomized control trial recruiting participants identified by the Hey Lemonade app developers as their key demographic targets (women aged 25 – 50 years). Outcomes from the research would be used to refine the mobile app to maximize impact and usability.
Key Research question(s):
1. Does use of the Hey Lemonade app (intervention condition) result in a significant improvement in coping self-efficacy or well-being in users compared to participants who do not use the app (control condition)?
2. How do participants in the intervention condition engage with and rate the user features or functions of the Hey Lemonade app? This includes objective components such as page views for specific app components and any in-app ratings of this content. It may also include duration of interaction within these.
Hypothesis:
Use of the Hey Lemonade app results in improvement in mood and perceived stress levels.
