In summary, given the low adjustment indices obtained in the CFA, our first hypothesis that the model of the 15-items version would fit the data was not supported and so we removed item 13 ("I get so focused on the goal I want to achieve that I lose touch with what I'm doing right now to get there") from the model based on the assumption of improving the adjustment and validity of the model.
The elimination of item 13 allowed a reduction to some extent on the Chi-Square value and also a slight improvement on one of the other adjustment indices.
The overview of the global adjustment indices for this second solution maintained an acceptable global model fit, CFI = .
Regarding the local adjustment indices (Figure 1; Table 1) we also observed that the coefficients of determination ([R.
Regarding the local adjustment indices we found similar results to those reported in Study 1: again item 13 does not reach the minimum criteria to be kept in the solution.
Using different adjustment indices, Kenny and her colleagues (Kenny, 1987; Kenny & Donaldson, 1991; Kenny & Rice, 1995) as well as others (Armsden & Greenberg, 1987; Lapsley et al.
Indeed, Larose and Boivin (1998) attributed the poor adjustment indices found for adolescents starting higher education to such stress.
To that extent, adjustment indices with values other than those that were expected were found for the cooperation dimension (specifically, GFI, AGFI and CFI values above .
The results show that the adjustment indices are very similar to those obtained in the original structure, with the exception of moderate improvements in the GFI and CFI indices, for which values did not meet the expected adjustment (see Table 5, restated version 1).
The results showed substantially higher adjustment indices compared to the original model, which, firstly, confirms the results of the exploratory factor analysis, considering that the cooperation items load on dimensions other than the original ones, and secondly, supports the consideration of removing the cooperation dimension from the model (see Table 5, restated version 2).
The results showed a significant improvement compared to the version originally proposed by the authors (see Table 5, restated version 3), revealing adjustment indices in accordance with expected values.
