Clinical Trial Summary

This is a four year project evaluating the effectiveness of a group-based lifestyle intervention (PeerFIT) supported by mobile health (mHealth) technology and social media compared to Basic Education in fitness and nutrition supported by a wearable Activity Tracking device (BEAT) in achieving clinically significant improvements in weight loss and cardiorespiratory fitness in young adults with serious mental illness (SMI).

Description:

The objective of this study is to evaluate the effectiveness of a group-based lifestyle intervention (PeerFIT) supported by mobile health (mHealth) technology and social media to promote weight loss and improved fitness in young adults with serious mental illness (SMI). The study is a two-arm randomized controlled trial conducted in real world mental health settings to evaluate the effectiveness of the 12-month PeerFIT intervention compared to Basic Education in fitness and nutrition supported by a wearable Activity Tracking device (BEAT) in achieving clinically significant improvements in weight loss and cardiorespiratory fitness. The investigators will enroll 144 overweight and obese (BMI ≥ 25) young adults ages 18 to 35 with SMI attending one of two community mental health who are interested in losing weight and improving fitness. The investigators hypothesize that PeerFIT compared to BEAT will be associated with a greater proportion of participants who achieve cardiovascular risk reduction at 6 and 12 months follow-up as indicated by either clinically significant weight loss (5% or greater) or increased fitness (>50 m on the six-minute walk test). The investigators also hypothesize that PeerFIT compared to BEAT will be associated with greater improvements in A1c and lipid profiles at 6 and 12 months follow-up. They will also investigate two theoretical mechanisms of action hypothesized to account for greater weight loss and increased cardiorespiratory fitness among participants assigned to PeerFIT: 1) improved self-efficacy and 2) increased peer support for health behavior change. The investigators hypothesize that the relationship between PeerFIT and weight loss and improved fitness will be mediated by improved self-efficacy and peer support for health behavior change.

Intervention

Behavioral:
• PeerFIT
The 12-month PeerFIT intervention consists of a 6-month intensive phase including: (a) once weekly 60-minute group weight management and exercise session led by a lifestyle coach; (b) once weekly one-hour physical activity session delivered in community settings; and (c) Facebook and mHealth technology (i.e., Fitbits, text messaging support) to increase motivation and facilitate self-monitoring and peer social support for health behavior change. Participants then transition to a 6-month lower intensity phase in which the 90-minute weight management sessions are discontinued. The groups will be conducted as open groups with a minimum of 4 and maximum of 18 participants at any given time.
• BEAT
Participants in BEAT will receive monthly individual lifestyle sessions delivered by a lifestyle coach including education, guidance, and support for self-monitoring behaviors (i.e., daily self-weighing and tracking daily steps) during the first six months of the study, plus text message reminders and encouragement for self-monitoring weight loss behaviors during the entire 12-month study period. Participants will receive materials with tips and strategies for healthy eating and increasing physical activity. They will also be given a wearable activity tracker (i.e., Fitbit Zip) to use with instructions for using the device. The first session with the lifestyle coach will be in person and thereafter by phone.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in weight	Participants' weight will be measured in pounds (lbs.) on a flat, even surface with the use of a high-quality, calibrated professional medical scale, with the participant wearing indoor clothing and no shoes.	Baseline, 6 months, and 12 months
Primary	Change in 6-minute walk test	After a baseline blood pressure has been obtained, participants are asked to walk a measured distance as far as they are able in 6 minutes.	Baseline, 6 months, and 12 months
Secondary	Change in weight loss self-efficacy assessed using the Weight Efficacy Lifestyle (WEL) questionnaire	The Weight Efficacy Lifestyle (WEL) questionnaire will be used to measure self-efficacy for weight loss. The WEL consists of 20 items designed to measure self-confidence to control weight by resisting overeating in certain tempting situations. The total score will be used in analyses. The items are scored on a 10-point Likert scale from 0 ("not confident") to 10 ("very confident") and total score calculated as the sum of individual item responses.	Baseline, 6 months, and 12 months
Secondary	Change in self-efficacy for exercise behaviors assessed using the Self-efficacy for Exercise Behaviors (SEB) scale	The Self-efficacy for Exercise Behaviors (SEB) scale will be used to measure participants' self-efficacy related to the ability to exercise despite barriers. The 12-item scale consists of common barriers that might affect participation in exercise (e.g., feeling depressed, socializing, stressful life changes, household chores). For each situation, participants use the scale from 1 ("I know I cannot") to 5 ("I know I can") to describe his or her confidence that they could exercise in the face of these barriers.	Baseline, 6 months, and 12 months
Secondary	Change in peer support for health behavior change assessed using the 24-item Social Provisions Scale (SPS)	Participants' level of perceived peer support will be measured with the 24-item Social Provisions Scale (SPS). The SPS assesses six types of support from social relationships (guidance, reliable alliance, reassurance of worth, attachment, social integration, and opportunity for nurturance) and the total score will be used in the analysis. The items are scored on a 4-point Likert scale from 1 ("strongly disagree) to 4 ("strongly agree") as it pertains to relationships with group members. Higher scores indicate greater perceived support from group relationships.	Baseline, 6 months, and 12 months
Secondary	Change in serum lipids	Lipids will be measured using the CardioChek PA Analyzer, a hand-held dual testing system that produces values for total cholesterol, LDL, HDL, and triglycerides using a multi-panel test strip and a single drop of blood acquired with a finger prick.	Baseline, 6 months, and 12 months
