Brief Summary
Childhood obesity within the United States has been a growing concern over the past number of years, and if not addressed, leads to detrimental health outcomes for youth as they move into adulthood. The literature suggests that over-eating, especially when framed in terms of food addiction, plays a key role in this epidemic; however, treatment options are time intensive, posing a profound logistical barrier for both the child and parent and often limits or prevents engagement. As research within the field of mHealth has grown, technology-based interventions have gained traction, specifically interactive smartphone applications (apps). Displacement theory, although not new, has been understudied yet provides a strong explanation and treatment plan for addictive type behaviors. The core of this theory posits that problems which one feels they cannot face nor avoid leads to repetitive and irrepressible behaviors; however, if a healthy coping behavior can be learned and utilized, then the unhealthy behavior will cease. The theory lends itself well to being adapted into an mHealth format, making it more easily accessible and more widely used. Grounded in displacement theory, the proposed study aims to develop an app-based weight loss intervention for adolescents with obesity. Information gained regarding the feasibility and acceptability of such an intervention can potentially be replicated and applied to other populations with various addictive behaviors. Helping those with addictive behaviors in a format that has little to no logistical barriers can have a substantial impact on public health. A novel smartphone app will be designed by key stakeholders and refined through the course of the study. 38 total adolescents (14-21 years old) with %BMIp85 will be recruited via various sources (e.g., clinic referrals, flyers, social media advertising) to participate in one of two stages of the study: the beta testing stage or the trial stage. Beta testing will enroll one group of eight teens to test the app for three weeks; participants will be assessed in-person pre- and post-intervention. After each group, the app will be modified to incorporate their feedback in order to promote youth engagement. The trial stage will enroll 30 adolescents to participate in a four-month intervention; participants will complete three assessments, baseline, post-intervention (both in-person) and one-month post-intervention (either in-person or virtually). The study will examine engagement and satisfaction with the app, as well as the intervention's impact on clinical outcome measures (weight and BMI, diet and snacking, and addictive behaviors related to food and substance use) and potential mediators/moderators (motivation for change, perceived stress, and distress tolerance).

Outcome Measures
Primary Outcomes (3)
Quantity of Engagement with App
Daily engagement as measured by minutes per day each participant spent in the app
4 months
Satisfaction with the App as assessed by the Treatment Satisfaction Questionnaire
The TSQ (Cox, Fergus \& Swinson, 1994) will be modified and used for this study to provide a quantitative assessment of participant satisfaction with the BrainWeighve app. The measure contains a nine item Likert-scale asking the participant to rate how satisfied they were with the app overall, its ease or difficulty of use, how satisfied they were with the impact the app had on their behaviors and weight loss, and if they would be likely to continue using it outside of a research study.
