Description of intervention(s) / exposure
The 21 Day Stress Detox is a digital intervention that sits on the HABITs (Health Advances through Behaviour Intervention Technologies) platform - a digital ecosystem developed by the University of Auckland to manage a body of research around the use of digital technologies for mental health support.
Participants on the 21 Day Stress Detox are directed to this platform, where they first register, then consent electronically to the study and proceed to complete baseline measures. Participants are then instructed (via a link) on how to activate the chatbot using their Facebook Messenger.
The chatbot consists of 21 days-worth of structured dialogues. Each day the chatbot initiates a new activity by sending the participant a message (e.g. "hi {participant name}, how's it going?"). The chatbot provides new content each day. The content of the intervention is steeped in cognitive behavioural (CBT) framework that includes relaxation, problem solving, identifying and challenging negative thoughts. Additionally interpersonal skills (communication, negotiation, assertiveness) are also part of the program. The focus of the intervention is to teach positive coping skills to manage stressful situations better.
Each engagement is designed to last around 5 minutes each day.
There are 3 stages covered over the 21 days, based on a CBT 3 component model:
1. Feelings - self monitoring, bodily sensation awareness, relaxation techniques
2. Thinking - cognitive re-appraisal & challenging negative thoughts
3. Behaviour - structured problem solving, positive communication, activity scheduling & systematic desensitisation for fearful situations.
Content is linked throughout to practical goal setting. A daily prompt encourages a growth mindset through gratitude journaling.
Content is delivered in short, easy to digest segments of psycho-education followed by examples and activities for participants to practice.
Participants are free to use the chatbot as much or as little as they choose during the 21 day period, usage data will be accessed via the HABITs platform to analyse adherence.

Outcomes
Primary outcome [1] 321319 0
The primary aim of this study is to determine whether a Chatbot (conversational agent) for emotional wellbeing is engaging for young adults. Exploration of engagement will be a composite primary outcome measured via usage data, satisfaction ratings and free text feedback from participants.
Usage data is collected for the duration of the 21 day intervention period. When a participant is interacting with the chatbot, the HABITs IT platform uses the HABITs API to send usage information to researchers - date when the chatbot was initiated, frequency of use, when the tool is used (time and date stamp), which activities/days are completed.
A scale developed for this study will be used as a satisfaction rating: 7 questions on a 5 point Likert scale, followed by an overall rating on a scale of 0 - 10. Text feedback from participants will be collected post intervention, and analysed qualitatively for themes around engagement, using Braun & Clarke's (2006) thematic analysis methodology.

Secondary outcome [5] 374755 0
Estimate of changes in self-reported stress level using momentary assessments within the chatbot conversation.

A daily momentary assessment is carried out in the form of a simple likert scale (quantified on a scale from 0-10) to collect self-report on perceived stress. Through the secure connection to our HABITS IT server, this information is collected from the chatbot to the HABITS platform/database.

Efficacy
Statistical methods / analysis
We have a target sample size of 40 for this study. Power calculations are not deemed necessary due to this being an open engagement and acceptability trial. We expect that a sample size of 40 participants should provide sufficient information to determine acceptability and to benchmark engagement.

Descriptive summaries including means, medians, ranges and standard deviations, frequencies and percentages will be used to describe chatbot usage behaviour and responses provided in the chatbot rating scale. These descriptive summaries will be estimated for the number of times the chatbot is accessed and the frequency/adherence over the 3 weeks.

Descriptive data, including means and standard deviations, will be used to analyse the within-chatbot Likert scales and the wellbeing measures. Changes over time will be estimated by calculating effect sizes for the Likert scales, wellbeing, stress and anxiety measures.
The secondary outcomes will be summarised for the all participants completing these scales, using within-subject paired sample t-tests. Although this is an exploratory study, it is still possible to make the null hypothesis assumption that there is no difference between measures at baseline and post intervention.
Analysis of results from this study will also look at estimation based on effect size and confidence intervals. For example, data will be visually represented using scatter plots of individual data points, mean differences will be represented with confidence interval bars.
