A poorly selected instrument can be costly to implement but yield little information for testing study hypotheses. Classifying self-report instruments and linking an instrument typology with study design and data modeling strategies can guide instrument selection. Consider the characteristics of physical activity that need to be sampled to address three types of research questions: (1) What is an individual's average physical activity, and how do people differ in average physical activity? (2) How does an individual's physical activity change over time, and how do people differ in rate of change? (3) What are the processes underlying variability in an individual's physical activity, and how do people differ in these processes?
