Childhood Obesity Clinical Trial

Official title: Testing Digital Technologies to Help Families Build Healthy Habits

Status Completed

Clinical Trial Summary

The current study is a randomized pilot trial to test the feasibility of a psychoeducational virtual reality experience to increase motivation for behavior change among children with overweight or obesity.

Clinical Trial Description

The investigators will be conducting a randomized pilot trial to compare a virtual reality (VR) experience to a video. Each provides child-friendly nutrition education as well as education on consideration of future consequences (episodic future thinking). The video acts as the control condition such that we might begin to understand whether the psychological presence produced by virtual reality might increase motivation for behavior change. The VR experience consists of a game in which participants play a racing game collecting healthy or unhealthy foods on the road. Collection of healthy foods increases speed, and collection of unhealthy foods decreases speed. Participants then play in the "future" where the food choices they made in the past also affect how they can move in the future game. If they collected mostly unhealthy foods in the past they move slower in the future, and if they collected healthy foods in the past they move faster in the future. However, foods collected in the future game can also change their speed, and participants are able to experience both future conditions i.e. they play in the future condition depending on if they ate healthily or not in the past, and then they play in the opposite future condition. A narrator in the game provides information on making healthy choices and about considering future consequences. The control video covers similar education on making healthy choices and considering future consequences. Additionally, the control video condition also includes a short computer-based game about healthy eating. The investigators will enroll 60 English-speaking children ages 6-12 with overweight or obesity who are not in behavioral treatment to address weight and one of their parents. Participants will be recruited from the community using methods such as social media and flyers and will complete a phone-screen to determine initial eligibility. Participants determined to be eligible over the phone will come for an in-lab visit. In-lab, children will provide verbal assent and parents provide written informed consent. Children and parents will complete baseline measures, including having height and weight taken, demographic survey questions, assessment of participants' eating and physical activity behaviors, and other survey assessments selected to evaluate participants' behavioral beliefs, behavioral intentions, affect, and motivation for behavior change. Post-video or -VR participants will take the same survey assessments aimed at evaluating behavioral beliefs, intentions, affect and motivation for behavior change. Additionally, all participants will take usability assessments to determine the acceptability of the video or VR and participants randomized to the VR will complete measures to evaluate how immersive the VR seemed. At 2-week follow-up participants will again report their eating and physical activity behaviors and some cognitive measures in order to see whether the VR may have impacted behavior and cognitions. ;
