Using Serious Games to Improve Social Skills in Autism
- Conditions
- AutismAutism Spectrum Disorder
- Interventions
- Behavioral: Placebo Control GameBehavioral: Intervention Video Game
- Registration Number
- NCT03690661
- Lead Sponsor
- Penn State University
- Brief Summary
The investigators will conduct a small-scale randomized control trial comparing the intervention game to an active control game, and will assess outcomes at multiple time points (pre-, post-, 6-month follow-up). These outcomes will include a wide range of behaviors that are measured along a continuum from controlled lab-based tasks to uncontrolled, real-world social interactions between dyads.
- Detailed Description
The investigators will conduct a small-scale randomized control trial comparing the intervention game to an placebo control game, and will assess outcomes at multiple time points (pre-, post-, 6-month follow-up). These outcomes will include a wide range of behaviors that are measured along a continuum from controlled lab-based tasks to real-world social interactions between dyads. The aims are evaluating 1) changes in the target mechanisms (social attention to faces, sensitivity to eye gaze cues) for the intervention relative to active control group, 2) engagement of intermediate mechanisms, including face-processing behaviors and real-world social communication behaviors, and 3) the relation between engagement of the target and intermediate mechanisms and symptom outcomes. Evidence of changes in autism social symptoms resulting from changing visual attention to faces and/or improved ability to understand eye gaze cues will provide clear evidence to inform a "go" decision about the therapeutic target for further clinical development.

Group Intervention Description Control Video Game Placebo Control Game Participants will play the Control Video Game for 3 months, 3 times a week for a minimum of 30 minutes each session Intervention Video Game Intervention Video Game Participants will play the Intervention Video Game for 3 months, 3 times a week for a minimum of 30 minutes each session
- Primary Outcome Measures
Name Time Method Primary Target Eye Gaze Mechanisms - Performance Accuracy 6 months Performance accuracy will be acquired from both a static and a dynamic task of eye gaze cue following, which will be analyzed separately (ie 6 months from pre-intervention).
Primary Target Eye Gaze Mechanisms - Visual Fixation 6 months Eye tracking measures of visual fixation will be acquired in both a static and a dynamic task of eye gaze cue following, which will be analyzed separately (ie 6 months from pre-intervention).
Social Symptoms - Social Skills Inventory System (SSIS) 6 months Social skills and problematic behaviors will be assessed via parent- and self-reported responses on the SSIS. These measures will be administered at multiple time points including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
Autism Behaviors - Social Responsiveness Scale 2nd Edition (SRS-2) 6 months To assess potential changes in autism-like behaviors and symptoms, parents will complete the SRS-2 at each of 3 time points (pre-intervention, post-intervention, 3-month follow-up after intervention completion).
- Secondary Outcome Measures
Name Time Method Intermediate Face Processing Mechanisms - Face Expression Identification - (CAM) 6 months Accuracy in face expression identification will be assessed via standardized measures including the face portion of the Cambridge Affective Memory task (CAM) at each time point including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
Face-to-Face Social Interactions - Visual Fixations 6 months Eye tracking measures (ie visual fixations) will be collected during a naturalistic social conversation. Additionally, eye tracking measures will be collected during an interactive cued eye gaze task, which requires participants to select the object that a real person is looking at. These measures will be assessed at multiple time points including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
Intermediate Face Processing Mechanisms - Face Identity (CFMT) 6 months Accuracy in face recognition will be assessed via standardized measures including Cambridge face memory task (CFMT) at each time point including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
Intermediate Face Processing Mechanisms - Object Identity (CBMT) 6 months Accuracy in object recognition will be assessed via standardized measures including Cambridge bike memory task (CBMT) at each time point including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
Intermediate Face Processing Mechanisms - Face Expression Identification - (RMET) 6 months Accuracy in face expression identification will be assessed via standardized measures including the face portion of the Reading the Mind in the Eyes Test (RMET) at each time point including pre-intervention, post-intervention, and 3 months after the intervention (ie 6 months from pre-intervention).
