Interactive Obesity Treatment Approach for Obesity Prevention in Adults

Status Recruiting

Clinical Trial Summary

Using a design-for-dissemination approach, this application proposes to use combined methods to adapt and pilot test an interactive obesity treatment approach (iOTA) for obesity prevention in early serious mental illness (eSMI) that uses text messaging to provide between-visit support. Derived from the lifestyle intervention used in the Diabetes Prevention Program, the parent iOTA targets diet, activity and adherence using web-based and health coach support.

Clinical Trial Description

Most obesity and related complications in serious mental illness (SMI) occur in the context of chronic psychiatric illness, but there are few treatments that work. Behavioral interventions face challenges with long-term effectiveness, implementation and sustainability. Medications have modest effectiveness at best, and/or pose serious side effect risks. This study focuses on prevention of chronic obesity by adapting and pilot testing a prevention-focused, interactive obesity treatment approach (iOTA) for use in persons with early-phase SMI (eSMI) experiencing initial weight gain, overweight or early-stage obesity. The intervention will be adapted from the most studied, effective iOTA, derived from the Diabetes Prevention Program. The parent iOTA uses health coaches who extend their sustainable reach with scalable, inexpensive, semi-automated text messaging. Using a formal evaluation process and a specific implementation science framework, planned adaptations for this application will address mechanisms to improve health-related awareness, insight and self-efficacy skills. Aim 1: Evaluate barriers and facilitators for intervention engagement, effectiveness and implementation, and identify needed adaptations of the prior iOTA for use in obesity attenuation in eSMI. Aim 2: Adapt the prior iOTA for use in obesity attenuation in eSMI, aiming to maximize acceptability, engagement, sustainable reach and target engagement for eSMI. Aim 3: Conduct a randomized pilot and feasibility study of iOTA-eSMI in a diverse sample of adults aged 18-45 with eSMI and initial weight gain, overweight or early class I obesity, comparing iOTA-eSMI to a health education condition. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
