Evaluating Efficacy of a Digital Game Therapeutic for Children With Autism

Study Overview
=================
Brief Summary
-----------------
The following study aims to assess the efficacy of the game-based digital therapeutic, GuessWhat, in improving adaptive socialization skills in children with Autism Spectrum Disorder (ASD). GuessWhat is a mobile application (available for free for iOS and Android) which contains a suite of games: pro-social charades, emotion guessing, and quiz. Participant families will use their personal smartphones to download the app and play it with their child according to a predetermined regimen.

Detailed Description
-----------------
The following study aims to understand the efficacy of the digital therapeutic, GuessWhat, in improving socialization outcomes in children with Autism Spectrum Disorder (ASD) after regular use over 8 weeks. We will use a cross-over, waitlist control design to examine outcomes after 8 weeks. GuessWhat is a mobile application (available for free for iOS and Android) which contains a suite of games: pro-social charades, emotion guessing, and quiz. Participant families will use their personal smartphones to download the app and play it with their child according to a predetermined regimen. The study will enroll parents who are at least 18 years old and have a child between 3 and 12 years old with a formal ASD diagnosis. Parents will be asked to complete two clinical outcome measure questionnaires immediately prior to and up to 1 week after playing GuessWhat with their child 3 times per week for 8 weeks.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in parent reported socialization based on the Vineland Adaptive Behavior Scales 3rd Edition (VABS-3) Parent/Caregiver Socialization Subscale, from baseline to week 8 | Vineland Adaptive Behavior Scales, 3rd edition (VABS-3) Socialization subscale of the Parent/Caregiver Comprehensive form will be administered online to the parents. Scores from the socialization domain of the VABS-III reflects one's functioning in social situations. The socialization subscale is up to 112 items depending on age and development, where raw scores are converted to Intellectual Quotient-type standard scores--v-scale scores (M=15, SD=3) where scores range from 1 to 24, and factor in age equivalents, growth scale values, and higher scores indicate better adaptive functioning. | Baseline (Week 0), Week 8 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Parental Stress Scale - from baseline to week 8 | The Parental Stress Scale is an 18-item parent report scale that evaluates the extent of parent stress. Scores range from 18-90, where higher scores indicate a higher level of Parental stress. | Baseline (Week 0), Week 8 | 
| Change in Emotion Recognition from baseline to week 8 | Study team will use an image based emotion recognition task where participants will select the emotion that corresponds to an emotional facial image in the form of a GIF (Graphics Interchange Format) image. Participants will select 1 of 8 available Ekman emotion labels for 16 facial emotional image stimuli presented in random order. Correct responses will be measured against a predetermined majority rules consensus of the emotional content of the GIFs. | Baseline (Week 0), Week 8 |
