This new Confirmatory Factor Investigation of one’s Private Union Measure (ECP) showed that the initial design advised of the authors didn’t provides a sufficient easily fit into the present day attempt ([chi-square] / df = 5.63, GFI = .93, CFI = .86, TLI = .84, RMSEA = .07), namely in terms of the [chi square] / df, CFI e TLI viewpoints. Into the white of these show and considering the parameters put (Browne Cudeck, 1992; Hu Bentler, 1999; Segars Grover, 1993) we made a decision to go ahead 
which have a keen Exploratory Foundation Study.
The significance of the effect of the relationship status on the level of personal commitment of the participants was evaluated by the ANOVA one way method, in which the normality (p <
The brand new Exploratory Factor Analysis of your Private Commitment Level (ECP), in the shape of Dominant Axis Factoring, found the latest unidimensional construction of your own scale, as just the accessibility to among section reached the brand new lowest Eigenvalue of 1. This is and apparent when you look at the translation of the scree-patch chart (Job, 2009).
The accuracy of your own dimensions is actually reviewed through the inner texture of size, as Cronbach’s alpha, as well as the adequacy of each and every item has also been confirmed (Desk step one). It absolutely was verified you to definitely items step 3 and you will 10 didn’t satisfy the minimum standards to possess introduction, for the loading to have items ten beneath the well worth felt acceptable, one another had poor goods-overall correlations and elimination of each other issues enhanced the worth of Cronbach’s alpha, to your worth just before removing are .80. In white for the research, the option was created to get rid of these two products in the study (; Nunnally Bernstein, 1994). These products correspond precisely towards a couple items the new experts consider as actually relative to the new meta-connection measurement, for this reason becoming officially enough its empirical differentiation regarding the remainder of what exactly and their exception to this rule from the measure. The very last unidimensional framework, without any known circumstances, explains % of the full variance, which have appropriate product-total correlations (Job, 2009) ranging from .36 and you can .60 with a total mediocre get of 5.56 (DP = .86). Brand new Cronbach alphas differ between .82 for the total sample, .83 and you may .81 correspondingly toward female and male take to. To your five subgroups, i acquired .82, .80, .70 and you may .84 respectively having professionals for the a dating relationships, matchmaking that have cohabitation, official partnership and married people. We could thus consider all of the internal structure indices since the a (Cronbach, 1970; ).
The average ECP scores in the current sample are as follows, 5.56 (DP = .86) for the total sample, 5.48 (DP = .86) for women and 5.70 (DP = .83) for men. This difference is significant F(1, 922) = ; p < .001; [[eta].sup.2]p = .02.
Continuing with the validation of the Personal Commitment Scale (ECP), we proceeded with the concurrent validity criteria analysis. The global values for personal commitment showed, as expected, significant positive correlations (p < .001) with the total RRF-R (.63) and with all its subscales (Passion, .64; Confidence, .51; Conflicts, .44; Intimacy, .45), which indicate that higher levels of personal commitment correlated with higher indices of relationship quality, in all its dimensions.
A mathematically significant effect of the connection standing on the individual connection degrees of the participants F(step three, 920) = nine
Once the described analyses were completed, they were followed by the exploration of the various relationship statuses present in the sample of participants (Table 3) with the results obtained by these in the Portuguese version of the scale thus validated, the ECP. 05 for three of the four types of relationship statuses) and homoscedasticity analyses W(3, 920) = 1.06; p = .298 were sufficiently robust to proceed with the analyses. 59; p < .001; [[eta].sup.2]p = .03 was observed.
