The CFI and NNFI values were both .99, and RMSEA indices were below .06.
The new CFA for the final model (model 2) has better adjustment scores, although they can still be considered sufferable ([chi square] = 260,981, p <.001, RMSEA = .08, NNFI =.91; [chi square]/df = 3.68, CFI = .93).
(Del Rey et al., 2015) tambien mostro adecuados valores de consistencia interna: [[OMEGA].sub.ciberagresion] = .94, [[OMEGA].sub.cibervictimizacion] = -91, [[OMEGA].sub.total] = .95, y el AFC confirmo la estructura bifactorial original de la prueba con optimos resultados, [[ji al cuadrado].sub.S-B] = 644.97; [[ji al cuadrado].sub.S-B]/(208) = 3.10; p < .001; NNFI = .97; CFI = .97; GFI = .97; RMSEA=.047 (IC 90% [.043, .052]); SRMR =.080; ECVI = .80; AIC = 228.96, (Herrera-Lopez et al., 2017).
The two-factor model showed good fit with CFI > 0.9 and NNFI > 0.9 while RMSEA = 0.11 > 0.08 which still indicates an acceptable fit.
The parsimonious model (constrained model) was selected if the following four criteria suggested by Cheung and Rensvold (2002) and Chen (2007) were met: (1) the constrained model did not generate a significantly worse fit than the unconstrained model (the multiplegroup baseline model) according to the chi-square test; (2) the difference in RMSEA ([DELTA]RMSEA) was lower than 0.01; (3) the difference in CFI ([DELTA]CFI) was greater than -0.01; (4) the difference in NNFI ([DELTA]NNFI) was greater than -0.01.

Moreover, all fit indices for the measurement model indicated a poor-fitting model, [chi square] (df = 9, N = 539) = 125.67, p < .001; GFI = .92; CFI = .87; RMSEA = .16; SRMR = .07; NFI = .87; NNFI = .79.
To assess model fit, relative [chi square] ([chi square]/df) less than 3; RMSEA less than 0.08; CFl greater than 0.95; SRMR less than 0.08; and NNFI greater than 0.95 were taken as acceptable threshold levels (Hooper et al., 2008; Kline, 2005).
The confirmatory factor analysis (CFA) showed good fit: [chi square] = 1047.22, g = 347, p < 0.001, [chi square]/gl = 3.02, Goodness of Fit Index (GFI) = 0.98, Normalized Fit Index (NFI) = 0.96, Non-Normative Fit Index (NNFI) = 0.97, Comparative Fit Index (CFI) = 0.98, Root Mean Square Error of Approximation (RMSEA) = 0.05.
