Factor structure, reliability, and validity of the Penn State Worry Questionnaire: differences between African-American and White-American college students.
This study examined differences in the factor structure of the Penn State Worry Questionnaire (PSWQ) between African-American (n=181) and White-American (n=180) college students. Results from a confirmatory factor analysis indicated that the traditional single-factor solution did not provide the best fit for the data from either ethnic group. A multiple-group factor analysis indicated that underlying structure of Factor 1 was roughly equivalent between ethnic groups. Structure of Factor 2, however, differed between groups. Specifically, item 10 loaded on different factors for each group. In support of these analyses, an exploratory factor analyses (EFA) among White-American participants indicated the presence of a two-factor model while an EFA among African-Americans indicated the presence of three factors. Despite some overlap in the overall factor structure between ethnic groups, African-Americans scored significantly lower on the PSWQ than the White-American group. Furthermore, among African-Americans level of ethnic identity was negatively related to state and trait measures of anxiety, but unrelated to measures of depression and worry.
