Stillwell Crossing, its health center and its residents are composite; the frameworks and trial evidence cited are published.
Rationale
The Stillwell Crossing profile found leisure-time inactivity at 1.57 times the county level and diagnosed diabetes at 1.64 times, in a population younger than the county. The target group for this plan is adults aged 18 to 70 whose most recent A1c at the neighborhood health center falls between 5.7 and 6.4 percent, the prediabetes range. The health center's registry lists about 610 such adults living in the two tracts. The plan is built on the strongest evidence available for this group: in the Diabetes Prevention Program trial, intensive lifestyle change aimed at 150 minutes a week of moderate activity and 7 percent weight loss reduced new diabetes by 58 percent over about three years compared with placebo (Diabetes Prevention Program Research Group, 2002).
Two Frameworks, Two Jobs
PRECEDE-PROCEED decides what needs changing and in what order. It works backward from the outcome, through the behaviors and environments that produce it, to the predisposing, enabling and reinforcing factors behind those behaviors, and then forward through implementation and evaluation (Green & Kreuter, 2005). Social Cognitive Theory designs how each activity works on a person, through self-efficacy, observational learning, outcome expectations, self-regulation and the social environment (Bandura, 2004). One framework chooses the targets; the other explains how an activity will change one person's behavior, and the plan uses each only for its own job.
PRECEDE: Diagnosing the Problem
Social and epidemiological assessment. Taken from the profile: diabetes and inactivity ratios well above the county, obesity at 1.24 times the county figure, and residents who describe diabetes as inevitable.
Behavioral and environmental assessment. Behavior: little leisure-time activity, especially in the evening. Environment: unlit parks, no continuous sidewalk to the grocery store, one bus route with long gaps, and warehouse shift schedules that change weekly.
Educational and ecological assessment. The factors are sorted into three groups, each tied to evidence from the profile or from interviews with the health center's two community health workers.
Predisposing factors, in the person: a belief that diabetes runs in families and cannot be prevented; low confidence about exercising after years without it; for some, unfamiliarity with the term prediabetes.
Enabling factors, in the environment and skills: no safe place to walk after dark; schedules that change weekly; family meals built around one cook who prepares food for six or more; limited English among some residents.
Reinforcing factors, in the social world: family members who see walking for exercise as odd; no visible local examples of people who have lowered their A1c.
Enabling factors receive the most activities in this plan, because a safe route and a schedule that fits shift work are preconditions for any motivation to matter.
The Intervention
A bilingual lifestyle change program following the curriculum of the National Diabetes Prevention Program, delivered at two sites: the community center gymnasium on weekday evenings and one church fellowship hall on Sunday afternoons. Two sessions of each week's content are offered at different times, so a participant whose shift changes can attend either. Groups are led by a trained lifestyle coach paired with a peer coach, a resident who completed the program in its pilot year. The program runs weekly for six months and monthly for six more.
Environmental changes are pursued alongside it. The health center and the community advisory board will ask the parks department to light the walking loop in the larger park, and in the meantime the community center will open its gymnasium for walking from 6 to 8 p.m. on program nights.
Activities Mapped to Constructs
1. Graded walking goals, starting at 10 minutes three times a week and rising to 150 minutes a week by week 12. Construct: self-efficacy through mastery experience; each small success builds confidence for the next goal (Bandura, 2004).
2. Peer coaches from the neighborhood lead sessions and share their own A1c changes. Construct: observational learning; residents see people like themselves succeed.
3. A1c results shared at months 3 and 6, with the change explained. Construct: outcome expectations; a changing number makes the link between effort and result concrete, and directly challenges the belief that diabetes is inevitable.
4. Step counters and a paper or phone log reviewed at each session. Construct: self-monitoring, part of self-regulation.
5. A cooking session for the family cook, open to whoever cooks in the household, on adapting existing recipes. Construct: reciprocal determinism; changing the home environment supports the participant's behavior.
6. Walking pairs matched by shift schedule. Construct: social support in the environment.
Goals
Participant goals, drawn from the national program: 150 minutes of moderate activity a week, and 5 to 7 percent weight loss at six months. Program goals: enroll 150 of the 610 registry adults in the first year, with at least 60 percent attending 9 or more of the first 16 sessions.
PROCEED: Handing Forward to Evaluation
Implementation, process, impact and outcome evaluation are named here and designed in the next unit. Process: sessions delivered, attendance and peer coach retention. Impact: weekly minutes of activity from logs and step counters, and the share of participants reaching 150 minutes. Outcome: percent weight loss, change in A1c, and, over three years, the share of participants who progress to diabetes compared with similar adults in the registry who did not enroll.

How this NU505 Unit 8 example is structured
Framework first, then model, then activities, then measures: the plan uses PRECEDE-PROCEED to decide what needs changing and in what order, and Social Cognitive Theory to design how each activity works on a person. The rationale is brief because the profile established the target. The diagnostic phases carry most of the analysis, and each factor listed is tied to evidence from the profile or from interviews with two community health workers, identified by role. Enabling factors receive the most activities, since a safe route and a schedule that fits shift work are prerequisites for any motivation to matter. The construct table makes the model visible: self-efficacy through graded walking goals, observational learning through peer coaches, outcome expectations through A1c feedback, and self-monitoring through step logs. PROCEED phases hand the evaluation to the next unit with measures already named.

NU505 Unit 8 questions, answered
How does a planning framework differ from a behavior model?
PRECEDE-PROCEED and frameworks like it lay out the work of building and judging a program: what to assess first, what comes next, how results are weighed. Social Cognitive Theory and its peers instead account for why one person takes up a behavior or abandons it. Strong plans usually pair one of each and state the division of labor openly, so both visibly do work.
Why does the plan target inactivity instead of diabetes itself?
Because a behavior change plan needs a behavior. Diabetes prevalence is the outcome the profile flagged, but a plan cannot act on prevalence directly. Inactivity among adults with prediabetes is modifiable, measurable and linked by strong evidence to later diabetes. Choosing it lets the plan set goals that can move within a year, while diabetes incidence becomes a longer-term indicator.
Can the plan borrow from national diabetes prevention programs?
Yes, and citing them strengthens the plan. The goals of 150 minutes of weekly activity and 5 to 7 percent weight loss come from that evidence base. Delivery still has to fit the community, which the example handles with bilingual sessions, two meeting times for shift workers, childcare and a lit local walking route.
