  1. Items 6, 10, and 12 were excluded from the analyses. Model modifications were conducted by correlating error terms of items. CI = confidence interval, RMSEA = root mean square error of approximation, CFI = comparative fit index, SRMR = standardized root mean square residual, PGFI = parsimony goodness-of-fit index
