The factor structure of the revised cheek and buss shyness scale in an undergraduate university sample

Objective: the present study examined the psychometric properties of the persian version of the revised cheek and buss shyness scale (rcbs) using confirmatory factor analysis among (n = 300) college students. method: a total of 300 undergraduate students participated in this study and completed the revised cheek and buss shyness scale (rcbs). a confirmatory factor analysis was performed to test diagnosis as a unitary construct and to test an earlier-reported two-factor model. results: results indicated that unidimensional measurement model of the rcbs did not provide the best fit for the data. then three measurement models were tested,and the results showed that a two-factor model taking into account differences in the direction of item wording provided a satisfactory and parsimonious fit to the data. multi-group confirmatory factor analysis was used to better understand the factorial invariance of the scale across genders,and indicated that two-factor structure of the rcbs was equivalent across genders. supplementary t-tests revealed no other gender differences on shyness. conclusions: the results provide initial support for the construct validity of the self-report version of the rcbs in college students.
