Physical activity measurement in health promotion and education research
Issues: The accurate and reliable measurement of physical activity (PA) is central to health education and promotion research and evaluation practice. From a research perspective, PA measurement allows researchers to model the correlates and determinants of PA. In terms of evaluation, measurement allows researchers to gauge the efficacy of interventions designed to increase or sustain PA. There are a wide variety of both direct and indirect PA monitoring techniques available to researchers and practitioners. The purpose of this research was to review methods of monitoring physical activity over time and identify best practices for application. Description: Measurement techniques analyzed included doubly labeled water, indirect calorimetry, motion sensors, global positioning system, global geographic information systems, heart rate monitors, direct observation, activity logs, and self-report questionnaires. Strengths and weaknesses, application, cost of the data collection and the accuracy of the resulting data was elucidated. Lessons Learned: PA is an important domain in health promotion and health education research. Accurate and reliable measurement of PA is critical to increasing the efficacy of health education interventions. Recommendations: Ultimately, the research questions that underlie an intervention should drive the type of measurement tool researchers employ. In making a final decision, expertise, resources, and funding of the program must be considered. Even the most advanced monitoring tools have limitations. Researchers must be aware of the limitations of the measurement they apply and make concerted efforts to reduce any associated biases or weaknesses. Recommendations and a flow chart for guiding decision making are provided.
