Abstract
OBJECTIVE: To evaluate the measurement properties of the Transtheoretical Model (TTM) questionnaire for sedentary behaviors among college students and to examine the validity and reliability of the developed TTM questionnaire. METHODS: Overall, 225 college students were recruited. For the 2-week test-retest reliability, a random sub-sample (N = 108) of the participants was used. RESULTS: Statistically significant differences were found across the stages on the tests of concurrent (χ(2) = 25.0, p < .001) and construct (p < .01) validity. In addition, the internal consistency reliability (Cronbach alphas from .73 to .88) and test-retest reliability (intra-class correlation coefficients ranging from .80 to .94) were high for the questionnaires. CONCLUSIONS: These results demonstrate high validity and reliability of the TTM questionnaire when applied to sedentary behavior.
