Wayne County Health Intervention: TPB-Based Strategy
This paper examines health disparities identified in the Wayne County Assessment (1999–2004) and proposes a structured community health intervention to address low insurance coverage and limited access to preventive care. Drawing on the Theory of Planned Behavior (TPB) integrated with the Transtheoretical Model, the paper outlines targeted strategies across three domains: shaping residents' attitudes through education and outreach, applying the subjective norm through social marketing and peer influence, and building perceived behavioral control through personalized support and nudging. The paper addresses the multilayered barriers facing Wayne County residents — including low income, limited education, and part-time employment — and recommends stage-specific approaches tailored to different segments of the population.

What makes this paper effective
- Grounds each intervention strategy in a named behavioral theory (TPB, Transtheoretical Model), giving the recommendations clear academic justification rather than relying on general intuition.
- Differentiates strategies by population subgroup (uninsured part-time workers, underinsured payroll employees, elderly residents), demonstrating awareness that a one-size-fits-all approach is insufficient.
- Supports each recommendation with peer-reviewed citations and real-world campaign examples (e.g., the UK Change4Life campaign), strengthening both academic credibility and practical plausibility.
Key academic technique demonstrated
The paper exemplifies theory application: it introduces a behavioral framework (TPB), unpacks its three components (attitude, subjective norm, perceived behavioral control), and then maps each component directly onto a distinct category of intervention strategy. This structured theory-to-practice translation is a hallmark technique in public health and health promotion writing at the graduate level.
Structure breakdown
The paper opens with a community needs assessment section that establishes the empirical basis for intervention. A brief theoretical framing section follows, introducing the TPB and its integration with the Transtheoretical Model. The bulk of the paper is organized into three parallel strategy sections — one per TPB construct — each with supporting evidence, examples, and stage-specific nuances. The paper closes with a references section formatted in APA style.
The Need for the Intervention
Several health-related issues emerge from the Wayne County Assessment 1999–2004. First, approximately 10 percent of the population lacks health insurance, a majority of whom are seasonal workers employed on a part-time basis. Worryingly, 22 percent of the county's payroll employees are either uninsured or underinsured. To some extent, the large population of uninsured persons is a result of structural factors such as low income and restrictive insurance plans that limit access to migrants who have lived in the county for less than two years. However, low education levels also play a significant role, as most uninsured residents lack knowledge about affordable health coverage plans such as Value Med. Data on educational attainment shows that only 63 percent of the population completed high school and only 14 percent were college graduates. It is likely, therefore, that most residents do not fully understand the value of having health insurance.
Secondly, access to preventive healthcare services is limited. The lack of health insurance and low income levels restrict residents' ability to seek care. For instance, 8.3 percent of the population lives below the poverty line, including 23.9 percent of the elderly aged above 65, who bear a greater burden of chronic illness. Further, most residents are employed on a part-time basis and depend on a daily wage, making it difficult to take time off work on weekdays to seek healthcare services. Such residents would typically be available on weekends, when most physicians are unavailable. Given the low education levels, it is likely that most residents do not understand the value of preventive care services. The lack of access to healthcare results in negative health behaviors, evident in the high prevalence of sexually transmitted diseases and high mortality from chronic illnesses. These factors indicate a clear need for intervention.
The Proposed Intervention
The proposed intervention is geared at increasing (i) health insurance coverage and (ii) access to preventive care. It is based primarily on the theory of planned behavior (TPB). However, Wayne County residents are at different stages — for instance, there are the uninsured, the underinsured, and the insured who may still not understand the benefits of preventive care. In this regard, the theory of planned behavior will be integrated with the Transtheoretical Model to identify the most plausible strategies for persons at different stages of change.
