Assessment told the team what is wrong and who is affected; the community nursing diagnosis named the risk and its drivers. Now comes the question Chapter 18 answers: what are we actually going to do, and how will we do it well? The answer begins with planning — and planning begins with choosing a theoretical framework or model to guide the work.
A Program An organized set of related activities to achieve an intended health outcome Full entry → is an organized set of activities designed to achieve an intended health outcome — a walking program, a vaccination campaign, a community garden project. Program planning Selecting and sequencing activities and resources to achieve outcomes Full entry → is the blueprint phase: selecting and sequencing activities, coordinating resources, and defining how success will be recognized. A Theory An explanation of why and how people and communities change Full entry → explains why people and communities change; a model turns that explanation into a step-by-step planning structure. This topic surveys the most common planning frameworks — the Community Action Model, PRECEDE-PROCEED, PATCH, and Intervention Mapping — plus logic models, the visual tool that ties a program's resources, activities, and results together. None is "the right model" for every situation; the nurse matches the model to the problem, the population, and the community's context.
Why this matters
Programs planned without theory are shots in the dark. Money is spent, activities happen, and nobody can say why they should work — or why they failed. A theoretical framework forces the team to make its assumptions explicit: we believe that if we increase access to fresh food (Enabling factor Skills, resources, access that make a behavior possible Full entry →), more families will eat more vegetables (behavior), and diabetes risk will fall (outcome). Those assumptions can be tested and refined. Funders increasingly expect logic models and theory-based rationales in proposals; exams and accreditation frameworks expect nurses to apply planning models, not just describe them. Most importantly, a well-planned program is an ethical program — it uses scarce resources where evidence and reasoning say they will help, and it can honestly report whether it helped.

Core Concepts
What a theoretical framework does in planning
A framework provides a systematic method to develop, implement, and evaluate a program. It answers questions the team might otherwise skip: Who should be at the planning table? What must we understand before choosing activities? What will we measure, and when? The assessment frameworks from Chapter 17 (MAPP, the Community Health Assessment Toolkit, CHANGE) guide assessment; the planning models in this topic take over after the diagnosis, guiding intervention design, implementation, and evaluation. Teams often combine tools — using PRECEDE-PROCEED for the overall arc and a Logic model A visual chain of resources → activities → outputs → outcomes → impact Full entry → to visualize the program.
Community Action Model (Healthy Places by Design)
The Community Action Model centers on sustained change through community capacity building. Six essential practices weave through every stage: a health equity focus, facilitative leadership, a culture of learning, strategic communication, sustainable thinking, and community engagement. Its action cycle is the "3P" cycle: Partner (build relationships with those who will shape and sustain the work), Prepare (develop capacity, plans, and resources), and Progress (implement, learn, adjust). The model fits when the goal is lasting change and the community's own organizations must carry the work forward after the program ends.
PRECEDE-PROCEED
PRECEDE-PROCEED is the most widely taught planning model in population health. Its name encodes both halves of the work.
PRECEDE Predisposing, Reinforcing, Enabling Constructs in Educational/Environmental Diagnosis and Evaluation Full entry → (Predisposing, Reinforcing, Enabling Constructs in Educational/Environmental Diagnosis and Evaluation) happens before the intervention. Its four phases: (1) define the outcome — assess what the community wants and needs; (2) identify the issue — select the most important problem an intervention can influence; (3) examine the predisposing (knowledge, beliefs, attitudes), reinforcing (rewards, social support), and enabling (skills, resources, access) factors that drive the behavior; (4) identify best-practice interventions.
PROCEED Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development Full entry → (Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development) guides implementation and evaluation through four phases: implementation (deliver as designed), process evaluation (is it being done as planned?), impact evaluation (did it change the targeted factors or behaviors?), and outcome evaluation (did it change the health problem itself?). PRECEDE-PROCEED's signature strength is forcing the team to understand why a behavior happens before choosing an intervention — a walk-to-school program will fail if the real barrier is a missing sidewalk.
PATCH (Planned Approach to Community Health)
PATCH is a practical, worksheet-heavy model built on PRECEDE, designed for communities with less planning experience. It emphasizes five critical elements: community participation, data-driven development, a comprehensive health promotion strategy, evaluation for timely feedback, and building community capacity. Its five phases: (1) mobilize the community; (2) collect and organize data; (3) choose health priorities; (4) develop a comprehensive intervention plan; (5) evaluate. PATCH's guidance to start simple and combine educational, policy, and environmental strategies — working through schools, work sites, and health systems — is a useful reminder that single-strategy programs rarely produce population-level change.
Intervention Mapping
Intervention Mapping (IM) is the most rigorous of the models — a six-step, theory-based protocol: (1) logic model of the problem (assemble the team, use the assessment, map the problem's causes); (2) logic model of change (identify determinants to target, define outcomes and objectives); (3) program design (choose evidence-based change methods and delivery formats); (4) program production (draft, pretest, refine materials); (5) implementation plan (assign responsibilities, state performance objectives, deliver); (6) evaluation plan (develop indicators, then evaluate). IM's power is traceability — every component traces back through a chain of evidence to the original logic model. Its cost is complexity: it demands time, expertise, and often formal training, so teams weigh that against the stakes of the program.
Logic models
A logic model is a one-page visual of the program's theory — the sequence from resources to results: resources/inputs (human, financial, organizational, and community assets), activities (the processes, tools, events, and actions the program carries out), outputs (direct products: sessions held, people reached), outcomes (changes in participants' knowledge, behavior, skills, or status; usually short- and long-term), and impact (the fundamental, longer-term change the program hopes to produce, often years away). The logic model connects the program's need (from the diagnosis) to its results. Logic models are used inside Intervention Mapping and are routinely required in grant proposals and evaluation plans.
Choosing a model for the situation
The choice depends on the problem, the population, the team's experience, and available resources. A small community with limited planning experience may start with PATCH's worksheets; a large, funded initiative tackling a complex problem may justify Intervention Mapping; a long-term coalition seeking durable environmental change may build on the Community Action Model; a team wanting an evidence-based, end-to-end arc will reach for PRECEDE-PROCEED. Whatever the choice, the model should be selected with the program planning team — including the people who will deliver, fund, and benefit from the program — and should be visible in the plan itself, so reviewers and evaluators can see the reasoning.
Common Confusions
| Do not confuse | With | Difference |
|---|---|---|
| Theory | Model | A theory explains why change happens; a model is a planning structure. Models often embed theories |
| Assessment models (Chapter 17) | Planning models (Chapter 18) | CHA frameworks organize assessment; planning models guide intervention design, implementation, and evaluation |
| PRECEDE | PROCEED | PRECEDE diagnoses before the intervention; PROCEED implements and evaluates after it |
| Process evaluation | Outcome evaluation | Process asks "did we do it as planned?"; outcome asks "did it change the health problem?" (impact evaluation sits between) |
| Outputs | Outcomes | Outputs are direct products (classes held, people reached); outcomes are changes in knowledge, behavior, or status |
| One "right" model | Best-fit model | No model is universally correct; the choice depends on the problem, population, team experience, and resources |

The same idea, in plain words
Explain it like I’m 10
Before building a treehouse, you draw a plan: what wood you need, what steps to do first, and what the finished treehouse should look like. Theories and models are the plan for health programs. They help the nurse decide why the program should work, what to do, who will do it, and how to check if it worked. A logic model is like a picture of the whole plan on one page: what we put in, what we do, what we get, and what changes for people.
Worked example
After the CHA, a county health department team writes a community nursing diagnosis: Risk of physical inactivity among families in Kenton County related to limited bike infrastructure, low bike-safety knowledge, and lack of access to affordable equipment. They select PRECEDE-PROCEED and work the PRECEDE phases: the desired outcome (more active families), the priority issue (inactivity linked to biking barriers), and the factors — predisposing (families think biking is unsafe), enabling (few bike paths, no helmets or bikes in many homes), reinforcing (no biking culture or social groups). For PROCEED, they implement a family bike program: safety classes (predisposing), a bike-lending library and new trail connections (enabling), and group rides with peer mentors (reinforcing). They plan process evaluation (were classes held?), impact evaluation (did knowledge, helmet use, and riding time change?), and outcome evaluation (did activity levels change?). They also build a logic model: inputs (grant, YMCA staff, volunteers) → activities (classes, group rides, helmet distribution) → outputs (families served) → short-term outcomes (safety knowledge, helmet use) → long-term outcomes (minutes of activity per week) → impact (reduced inactivity and chronic disease risk). Every funding report and evaluation question now has an answer because the planning was theory-driven from the start.
Key takeaways
- A program is an organized set of activities for an intended outcome; program planning is the blueprint phase; theories/models make it systematic.
- Planning models follow the diagnosis from Chapter 17 — they guide intervention design, implementation, and evaluation, not assessment.
- PRECEDE-PROCEED: PRECEDE = 4 diagnosis phases before the intervention (outcome → issue → predisposing/reinforcing/enabling factors → best practices); PROCEED = implementation + process, impact, and outcome evaluation.
- Community Action Model: 6 essential practices + the Partner–Prepare–Progress (3P) cycle; built for sustained community change.
- PATCH: worksheet-based, for less-experienced communities; 5 phases; combines educational, policy, and environmental strategies.
- Intervention Mapping: 6 rigorous steps from logic model of the problem to evaluation; every component traces back to evidence.
- Logic model = resources → activities → outputs → outcomes → impact; one page showing the program's theory of change.
- Match the model to the problem, population, team experience, and resources; choose it with the planning team.

6 review questions from the chapter. Try each one, then open the answer.
What is the difference between PRECEDE and PROCEED, and which comes first?
Show answer
PRECEDE is the diagnostic half — four phases before the intervention (define the outcome, identify the issue, examine predisposing/reinforcing/enabling factors, identify best practices). PROCEED is the implementation/evaluation half — implementation plus process, impact, and outcome evaluation. PRECEDE always comes first: understand the problem before intervening.
Name the three categories of factors PRECEDE asks the team to examine, with one example of each.
Show answer
Predisposing factors — knowledge, beliefs, attitudes (e.g., families believe biking is unsafe); enabling factors — skills, resources, access (e.g., no bike paths or helmets); reinforcing factors — rewards and social support (e.g., peer group rides that make biking a social norm).
What are the five components of a logic model, in order?
Show answer
Resources/inputs → activities → outputs → outcomes → impact. Resources are what you invest; activities are what you do; outputs are the direct products; outcomes are changes in participants; impact is the fundamental long-term change.
How does Intervention Mapping differ from PATCH in rigor and in the communities they suit?
Show answer
Intervention Mapping is a six-step, rigorous, evidence-traceable protocol requiring time and expertise; PATCH is a practical, worksheet-driven model for communities with less planning experience. Choose IM for complex, high-stakes programs with capacity; PATCH to get a capable program started with modest resources.
Why does the Community Action Model emphasize the "3P" cycle and the six essential practices?
Show answer
Because the model targets sustained change: the six essential practices keep the work values-driven, while the Partner–Prepare–Progress cycle builds the relationships, capacity, and learning loops needed for the community to carry the work forward after external support ends.
Why should a team choose the planning model before writing the program plan, rather than after?
Show answer
Because the model determines what must be assessed, what the intervention includes, what is measured, and how evaluation is structured. Choosing the model first forces explicit assumptions and coherent planning; picking a model afterward means retrofitting a label onto an unstructured plan.
