If there is a common structure to decision making across a broad range of health behaviors, as these results suggest, these patterns can have profound theoretical, empirical, and practical implications. Theoretically, these results support the TTM per- spective that there is a common structure or pattern to behavior change across very diverse problems and populations. Empirically, hundreds of thou- sands of data points can be represented by this rela- tively clear and concise theoretical integration of stages and pros and cons of decision making. Practi- cally, developers and practitioners of health behav- ior change programs can master a small number of behavior change constructs that can help produce progress with a large number of behaviors.
