How It Works

Complete Real Life Adventures

The Guardians: Paradise Island is a unique game that rewards you for helping out your own mental health! Paradise Island provides the motivation that we all sometimes need to get up and help ourselves live better lives.

Based on Established Therapies

Every day, Paradise Island will prompt you to partake in a therapy known as Behavioral Activation. The Guardians: Paradise Island uses an abridged version of the therapy Behavioral Activation, which is a key part of Cognitive Behavioral Therapy (CBT)! The therapy asks you find tasks that are meaningful to you, go do them, then reflect on how they made you feel.

Our Publications

A Quantitative Feasibility Assessment Using Data from a Behavioural Activation Therapy App

This paper looked at the anonymized data gathered from Guardians: Unite the Realms and determined that machine learning algorithms can be used to analyze users’ ratings of their daily adventures and accurately suggest new adventures they will like and find helpful! We really look forward to adding this into our games to help people help themselves.

The Guardians: Designing a Game for Long-term Engagement with Mental Health Therapy

Based on Guardians: Unite the Realms, this paper shows that Guardians improves long-term engagement with mental health therapies over the typical mental health app. In fact, Unite the Realms ended up with over 2.5x the long-term retention of top mobile apps, and is in the top 15% of mobile games in terms of retention! Not only that, but we showed that in 72% of days when people played the game, they also completed real world tasks. And since over 80% of those tasks improved users’ moods, that’s a lot of people we helped!

Use of In-Game Rewards to Motivate Daily Self-Report Compliance: Randomized Controlled Trial

Based on a prototype idle game, we showed that we could motivate pediatric populations to fill out daily mood diaries in exchange for in-game rewards. Over 50% more participants hit our target response rate when given the game over a normal app. This became the basis of The Guardians Project!
