The χ2 (2) for the one-factor model was 7.48, p = .02. However, because evaluation of nested models with chi-square values was not relevant to the analyses, overall goodness of fit of the model was evaluated using root mean square error of approximation (RMSEA), comparative fit index (CFI), the Tucker-Lewis index (TLI), and the weighted root mean residual (WRMR). According to Hu and Bentler (1999), acceptable model fit was defined by: RMSEA ≤.06, CFI ≥ .95, and TLI ≥.95 or greater. For our one-factor solution, RMSEA was .06 and CFI was .97, indicating reasonably good fit. The TLI of .91 was somewhat low, but still in the range indicative of acceptable model fit (Bentler, 1990). The WRMR was .98, less than the cut-off value of 1.0 which has previously been shown to provide an acceptable error rate (Yu, 2002). The overall fit of the one-factor model was also supported by an absence of any localized areas of strain. None of the standardized residuals from the model were larger than 1.0 (as these are roughly equivalent to z-scores, a value of
