Evaluation Plan for a Cardiovascular Disease Prevention Program
Introduction
The escalating burden of cardiovascular disease (CVD) among people of color in Oklahoma City, Oklahoma, presents a critical public health challenge. In response to this, a targeted intervention program has been developed with the aim of reducing CVD risk factors in this vulnerable population. This paper outlines the Evaluation Plan designed to assess the effectiveness of this program, beginning with a rationale for selecting a specific impact evaluation question that focuses on comparing the health outcomes of the program participants with a similar population not receiving the intervention. This is followed by a description of the evaluation design, specifically the Non-equivalent Groups Design (NEGD). It then discusses the various threats to internal validity, and outlines strategies to mitigate these threats. Data collection methods and measurement tools used in the evaluation are also described. Finally, the paper discusses how the results of the evaluation will be used.
Evaluation Question
What is the effectiveness of a cardiovascular disease prevention program among people of color in Oklahoma City, compared to a similar population in a neighboring city without the program?
Rationale for Choosing This Question
The selected impact evaluation question is important to the objectives of the health promotion program aimed at reducing cardiovascular disease among people of color in Oklahoma City. This question targets the heart of the program's intended effect evaluating whether the intervention directly contributes to lower risk factors associated with cardiovascular diseases, such as improved dietary habits, increased physical activity, and better management of blood pressure and cholesterol levels. Through a focus on these outcomes, the evaluation aims to quantify the program's direct benefits. The rationale for choosing this question lies in its potential to provide clear, evidence-based results that can demonstrate the program's success or highlight areas needing improvement. This outcome-oriented approach can help with securing continued funding and support, influencing policy decisions, and justifying the expansion of the program to other communities with similar demographics and health challenges.
Evaluation Design
The Non-equivalent Groups Design (NEGD) is suited for this evaluation due to practical constraints that make random assignment unfeasible. In the NEGD, two groups are compared one that receives the intervention (experimental group) and another that does not (control group). These groups are selected based on shared characteristics that are as similar as possible except for the intervention itself, reducing the likelihood of selection bias affecting the outcomes (McKenzie et al., 2022). The notation O1 X O2 | O3 O4 explained in the context of this design is as follows:
1. O1 (Pre-test observation of the experimental group): This involves collecting baseline data on the experimental group before the intervention begins. Metrics include initial health literacy levels, cardiovascular health stats, and behavioral factors related to cardiovascular risk.
2. X (Intervention): This represents the implementation of the cardiovascular disease prevention program, which include educational workshops, community health fairs, and direct healthcare services.
3. O2 (Post-test observation of the experimental group): Following the intervention, this observation assesses changes from the baseline to determine the interventions impact on the experimental group.
4. O3 and O4 (Pre-test and post-test observations of the control group): Similar data are collected from the control group, which does not receive the intervention, at parallel times. This group serves as a baseline to understand changes that occur without the intervention, providing a counterfactual against which the programs effects can be measured.
Significance of the Evaluation Design
The strength of the NEGD lies in its ability to suggest causality more strongly than non-experimental designs, even though it cannot fully match the causal inference powers of randomized controlled trials (Mildner, 2013). In using pre- and post-tests in both the experimental and...

Refining Program Components
The data collected and analyzed from both the quantitative and qualitative measurement tools will inform the ongoing refinement of program components. It will thus be possible to identify which aspects are most beneficial and which may require modification. For example, if data indicate that certain educational components of the program are not effectively improving health literacy, these can be redesigned to be more engaging or informative. This iterative process of refinement is helpful in driving the overall quality of the program.
Policy Advocacy
Successful outcomes from the evaluation can be used to advocate for expanded funding and policy support. Evidence of improvements in cardiovascular health metrics among participants, such as reduced cholesterol levels or increased physical activity, would be compelling evidence of the programs value. This evidence can be used to influence policymakers and stakeholders, making the case for increased resources or broader implementation of the program. The ability to show data-driven success stories also improves credibility and strengthens the argument for scaling up the intervention to benefit a larger population.
Community Engagement and Trust
Showing the effectiveness of the program is important for building and maintaining trust within the community. When participants see real improvements in their health outcomes, or when the program is publicly recognized for its success, it boosts community trust and engagement. This, in turn, can lead to higher participation rates, as more individuals are likely to join a program that they perceive as credible and beneficial. Additionally, success stories from within the community can serve as powerful motivators for others.
Conclusion
This Evluation Plan outlines a structured approach to assess the effectiveness of a cardiovascular disease prevention program targeting people of color in Oklahoma City. In addressing internal validity threats and using robust data collection methods, the evaluation aims to provide clear evidence of the…

This occurs when resources are scarce and potential uses of those scare resources are numerous in nature.
