Assignment 2: Program Evaluation
Assignment 2 Program Evaluationin This Assignment You Will Be Consid
In this assignment, you will develop an evaluation plan for a province-wide smoking cessation campaign in British Columbia, focusing on assessing whether the campaign's logic functions as intended—from awareness and knowledge increase to attitude change and behavioral outcomes. You will outline the main features of your evaluation design, describe its implementation process, address potential threats to internal validity, and consider aspects of statistical, construct, and external validity. The report should demonstrate a clear, organized, and ethical approach to evaluating the effectiveness of the campaign using appropriate research methods.
Paper For Above instruction
The evaluation of a public health campaign, such as the smoking cessation initiative in British Columbia, requires a comprehensive design that effectively tracks the influence of media-based interventions on targeted behaviors and attitudes over time. Given the campaign's scope and the challenge of establishing a control group within the region, a quasi-experimental, longitudinal cohort study is suitable. This approach allows for the assessment of changes within the same population over multiple time points, which aligns with the campaign's phased implementation strategy.
Main features of the evaluation design
The core of the proposed evaluation is a repeated-measures design involving baseline measurements prior to the campaign's initiation, followed by subsequent assessments after each campaign segment. Specifically, a structured survey would be administered to a representative sample of 20- to 30-year-olds in British Columbia before the campaign starts (pre-test), immediately after each segment (post-test 1 and 2), and finally, at the campaign's conclusion (post-test 3). This design enables the observation of temporal trends and the attribution of observed changes to campaign exposure.
To complement survey data, media exposure metrics such as media reach and frequency will be collected through media monitoring services, providing measures of campaign "dose." Additionally, the inclusion of a brief qualitative component—such as focus groups or interviews—can help examine nuanced attitude shifts and barriers to behavior change. The survey instruments should include indicators of campaign awareness, knowledge of smoking risks, attitudes towards smoking, and smoking behaviors (attempts, reductions, cessation).
Implementation of the evaluation
The evaluation begins with the development of a representative sampling frame, possibly through random digit dialing or online panels, to recruit participants reflective of the province's demographic composition. Baseline data collection will establish initial levels of awareness, knowledge, attitudes, and behaviors related to smoking. Following the baseline, the survey will be repeated after each media segment to assess immediate and short-term impact.
Key to implementation is ensuring high response rates and consistent measurement tools across time points. Data collection should be standardized, and efforts made to control for potential confounders such as concurrent anti-smoking policies or societal shifts. Data analysis would involve repeated-measures ANOVA or mixed-effects modeling to detect statistically significant changes over time. Furthermore, stratified analyses could examine differences by sociodemographic variables, ensuring the evaluation captures diverse responses within the population.
Monitoring campaign reach and media exposure, along with adjusting sampling procedures as needed, will help interpret the findings within the context of actual campaign exposure levels. Ethical considerations include informing participants about confidentiality and voluntary participation and obtaining necessary approvals from ethics review boards.
Addressing rival hypotheses and internal validity threats
Potential internal validity threats include history effects (other concurrent campaigns or policies), maturation (natural changes over time), and testing effects (participants' responses influenced by repeated surveys). To mitigate these, the repeated-measures design includes multiple assessments, allowing differentiation between campaign effects and extraneous influences. Collecting contextual data on other interventions and societal trends helps account for external factors.
Furthermore, a comparison with historical data or regional data from similar provinces not exposed to the campaign can provide a reference point to better attribute changes to the intervention, although this is limited within a single-region study.
Addressing statistical, construct, and external validity
Statistically, the use of repeated-measures models will help control for individual differences and increase the precision of estimates. Handling missing data through imputation techniques enhances the robustness of the findings. Ensuring the sample's representativeness bolsters external validity, allowing the results to be generalized to the broader population of young adults in British Columbia.
Construct validity is maintained through the rigorous development of measurement instruments that accurately capture awareness, knowledge, attitudes, and behaviors related to smoking. Pilot testing survey items reduces measurement error. External validity depends on the sampling strategy; employing random sampling methods and ensuring demographic diversity help achieve findings applicable to the entire target demographic.
In conclusion, this longitudinal, repeated-measures evaluation design provides a comprehensive approach to assessing the effectiveness of the smoking cessation campaign. By capturing data at multiple points, adjusting for potential confounders, and employing robust statistical analyses, it offers a strong framework for understanding whether and how the campaign influences awareness, knowledge, attitudes, and behaviors among young adults in British Columbia.
