Abstract: Objective To revise the time management habit scale and examine its reliability and validity.Methods 1042 college students were assessed with time management habit scale (TMH) and time management disposition scale(ATMD). All students were randomly split into two samples with equal size. Exploratory factor analysis(EFA) was conducted to obtain the structure of TMH with one sample and then the stability of the new structure was examined by confirmatory factor analysis(CFA) with another sample. Results EFA extracted three factors that explained 49. 577% of the whole variance. CFA analysis that the three-factor model represented the data better than the four-factor model. The Cronbach' s alphas reliability was 0.9076. The three-factor was 0.8324～0.8459. The test-retest reliability was 0.766 (P ＜ 0. 01 ). Conclusion The Cronbach' s alphas reliability, testretest reliability, content validity and construct validity of new TMH accord with psychometric demands.
