Model 1: four-factor model identified by Li and Arthur [12] and in this research, Model 2: two-factor model suggested by Startup in 1999 [10], and Model 3: three-factor model suggested by Kim and Miklowitz in 2004 [32].
aModel fit indices tested with paths (correlations) set-up between the hypothesized factors in each model.
χ 2: Chi-squared goodness of fit; df: degree of freedom; P value (a good fit if P≧0.1); GFI: goodness-of-fit index (ranging from 0 to 1, a good fit if GFI≧0.9); AGFI: adjusted goodness of fit index (similar to GFI, a good fit if AGFI≧0.9); TLI: Tucker-Lewis index (0.90–0.95 acceptable, a good fit if TLI > 0.95); RMSEA: root mean square error of approximation (a good fit if RMSEA≦0.05); SRMR: standardized root mean square residual, (a good fit if SRMR < 0.05); WRMR: weighted root mean residual (a good fit if WRMR < 0.90).
