The aim of this project is to trial the protocol of a park-based physical activity (PA) intervention in adults with severe mental illness (SMI) in a community mental health center's peer support program.
Aim 1: Test the feasibility and acceptability of a park-based PA intervention led by Certified Peer Specialists (CPS) and adapted for adults with SMI. Rationale: Park-based interventions led by CPSs represent a novel approach to increase program satisfaction and adherence to PA behavior change in persons with SMI. Hypothesis 1A: Most (80%) people offered the intervention will participate most of the time (≥2 day/week). Hypothesis 1B: CPSs and SMI patients will express satisfaction with the program (6 on an 8-point scale). Aim 2: Test the effectiveness of a park-based PA intervention led by CPSs on increasing PA and improving fitness in adults with SMI. Rationale: Park-based PA is associated with greater intensity and duration of PA, better fitness, and less obesity and depression, issues that are especially problematic for adults with SMI. Hypothesis 2A: People enrolled in the intervention will engage in more PA than at baseline (90min moderate to vigorous PA (MVPA)/week). Hypothesis 2B: The intervention will result in improved fitness (6 min walk test) relative to baseline.

Physical activity sessions will take place 3x/week over six weeks and will take between 45 and 60 minutes for each session. The sessions will be led by a Serenity Behavioral Health CPS as part of the PEERS program and will be supervised by research staff. Sessions will occur at public parks. Transportation to the park will be provided by Serenity Behavioral Health. Structured activities will include a warm-up, a mix of simple exercises requiring minimal supplies (such as walking, basic aerobic movements, and body weight resistance exercises), and cool-down. Sessions will be held in green park environments with shade, restrooms, and level walking paths.

Percent attendance
Feasibility will be assessed by attendance to park PA sessions (0-100%). Higher attendance indicates greater engagement with the intervention.
Time frame: During 6-week intervention period
Participant satisfaction
Acceptability will be assessed via participant satisfaction, measured using an abbreviated version of the Physical Activity Class Satisfaction Questionnaire (PACSQ). PACSQ is a valid measure for capturing client satisfaction within exercise classes in the following nine dimensions: mastery experiences, cognitive development, teaching, normative success, interaction with others, fun and enjoyment, improvement of health and fitness, diversionary experiences, and relaxation. Each of the dimensions of satisfaction is measured using an 8-point Likert scale, with responses ranging from 1="No satisfaction" to 8="Very satisfying". PACSQ has shown acceptable reliability in each of its subscales (all α's ≥ .85), and survey items are highly correlated with participants' intentions to attend a similar course in the future.
Time frame: 8 weeks
Change in Physical Activity
Fitbit min/week moderate to vigorous physical activity. Greater min/week physical activity is better.
Time frame: Baseline, during 6-week intervention period
Change in Aerobic Fitness from Baseline at 8 weeks
6-minute walk test. Greater distance indicates better fitness.
Time frame: Baseline, 8 weeks
