p < .001 = Cronbach’s alpha; S.E. = Standard Error

Factor loadings are standardized. The values in parentheses represent the 95% confidence interval for RMSEA. Suggested cutoffs for good model fit are: Bentler’s Comparative Fit Index > 0.95, Root Mean Square Error of Approximation < 0.06, and Standardized Root Mean Square Residual < 0.05.
