Abstract

Objectives: To test the measurement properties of the Transtheoretical Model (TTM) relative to physical activity (PA) behavior. Design: Participants from an ethnically diverse sample in Hawaii (N = 700) completed questionnaires capturing each TTM construct. Method: The current study examined the factorial validity and longitudinal invariance of TTM constructs recently revised for PA. Results: Factorial validity was confirmed for each construct using confirmatory factor analysis with full-information maximum likelihood. Longitudinal invariance was evidenced across a shorter (3-month) and longer (6-month) time period via nested model comparisons. Conclusions: The questionnaires for each validated TTM construct are provided, and can now be generalized across similar subgroups and time points. Further validation of the provided measures is suggested in additional populations and across extended time points.
