Detailed 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: iOTA text messaging intervention
There will be a 6 month "active" treatment phase consisting of monthly meetings with a study health coach to develop reasonable health goals and interactive text messaging to provide daily support and self-monitoring of behavior change goals between in-person visits.
Participants may receive phone calls between visits from their health coach for additional support if needed.
Following the active treatment phase, participants will receive daily health-related text messages for another 3 months.
|
Over 6 months, participants in the iOTA arm will have monthly in-person visits with a health coach who will work with the participant to set goals for the upcoming month related to healthy eating and activity.
The participant will receive daily text message health tips related to their goals, and will be prompted once a week to respond with a text indicating their weight and how they are doing with their goals.
Following the 6-month active treatment phase, participants will receive text messages only for another 3 months.

PLACEBO_COMPARATOR: Health Education text messaging intervention
There will be a 6 month "active" treatment phase consisting of monthly in-person visits with a health coach to learn about healthy eating and activity behaviors, including developing readiness for health behavior change.
Participants will not set specific health goals, but will receive weekly text messages about general health tips related to their in-person visits.
Following the active treatment phase, participants will receive daily health-related text messages for another 3 months.
|
Over 6 months, participants in the Health Ed arm will also have monthly in-person visits with a health coach who will provide education on energy balance and problem-solving.
Specific goals will not be set, but the health coach will assist participants in problem-solving any challenges.
Participants will receive a weekly automated motivational text message health tip from the study related to what they learned in their health coaching sessions.
Following the 6-month active treatment phase, participants will receive text messages only for another 3 months.

Change in Self Efficacy for Healthy Eating and Exercise
Time Frame: Baseline, 4, 8, 12, 16, 20, 24 and 36 weeks
|
This questionnaire includes 32 questions in two domains of self efficacy: 1) healthy eating and 2) exercise.
Respondents are asked to recall how confident they have felt in doing positive health behaviors since the last study visit.
Responses are on a likert scale of 1 - 5 (1 - 2 = I know I cannot do; 3 - 4 = Maybe I can; 5 = I know I can).
|

Change in Psychophysical Skills & Insight
Time Frame: Baseline, 4, 8, 12, 16, 20, 24 and 36 weeks
|
This questionnaire includes 10 questions, with three separate subscales (Self-determination, Cognitive control and Interoceptive Awareness).
Respondents are asked to rate their own skills since the last study visit.
Responses are on a likert scale of 1-5 (1 = never, 2 = rarely, 3 = sometimes, 4 = often, 5 = always).
Scores are generated for each subscale, as well as a total score.
Higher scores indicate greater degree of psychophysical awareness & skills.
