The Penn State Worry Questionnaire(PSWQ) is a measure of worry phenomena and has been demonstrated valid in cross-cultural populations. The present study examined the factor structure and psychometric properties of the Chinese version of PSWQ(Ch-PSWQ) in a Chinese college sample(n=1243). Exploratory factor analysis of the Ch-PSWQ revealed a two-factor solution(engagement of worry and absence of worry). Confirmatory factor analysis and model comparison supported that the model of one factor with method effect provided the best fit to the data. The Ch-PSWQ and its factors evidenced good internal consistency and both convergent and discriminate validity. The present study supports the opinion that the second factor of PSWQ not only contains the component of evaluating pathological worry,but also might represent other traits.
