Desk step 1 suggests might descriptive statistics on reviewed things additionally the IDI (Item Problem List) value

It was not observed that the distribution from reviewed situations differed significantly on the regular shipments. Likewise, IDI directory failed to prove the presence of floors or roof consequences from the analysis (merely in the case of product nine “We remain looking one thing” performed hook ceiling impression reveal for everybody around three examples). Volume investigation getting private try affairs showed no problems having investigation granulation. In that respect, every affairs was indeed found in then analyses. This may be on account of response set prejudice, including personal desirability and acquiescence.

Factorial Validity

By applying the Velicer MAP method, it was found that the optimal number of components to be extracted is one, which confirms the original factor structure of the questionnaire. The effect was observed both when the results of the interviewees were analyzed together and when they were divided into validation groups. Subsequently, the result obtained by MAP was verified by means of principal component analysis with oblimin rotation. As the criterion for the number of factors to be isolated, the eigenvalue was set to be equal to at least 2. Assumptions of factor analysis were met [KMO = 0.908; chi ( 91 ) 2 = 1; p < 0.001]. The created factor explains a total of % variance of the questionnaire. The factor structure was checked for the three validation groups, there were no significant differences in the size of explained variance: early adulthood (%), young adolescence (%), problem group (%). The obtained factorial results correspond to the expected one factor dimensions of the original version of the Questionnaire.

Synchronous studies indicated that a-one-grounds solution try the best for everybody three the newest samples. Due to the fact indicated for the Table 2, the one-grounds model displayed good items loadings and similar efficiency have been noticed regarding your product loadings across the around three trials. Every products stacked saliently with this grounds, that have goods loading ranged between 0.505 and you can 0.719 in early adulthood attempt. From the kids it actually was between 0.464 and you may 0.770 as well as in the challenge classification it absolutely was ranging from 0.400 and you may 0.668. A low loadings remained significant, guaranteeing the coherent construction of Polish particular the device.

The next step included contrasting the results of one’s design installing methods from other offered studies. There are no high differences when considering the new model installing score acquired from the confirmatory factor analysis (CFA). This new Polish style of RS-fourteen displayed a defined one-dimensional basis framework having reples.

While doing so, it needs to be indexed one to from the around three take to recognition groups no biggest variations was in fact noticed. Detail by detail email address details are given from inside the Dining table step three.

Cross-Category Legitimacy Reliability of Balances

Cronbach’s leader coefficient was applied to examine the internal structure regarding the fresh gotten survey indications. The results was demonstrated less than.

The precision of your created factor are 0.853 (total test) in the recognition demo, and therefore confirms its high surface. Immediately after department to the validation organizations, zero extreme differences in scale feel have been noticed. Cronbach’s alphas ranged between 0.824 and you may 0.871 along side around three samples:

The highest accuracy of your received factor are by the young grownups (? = 0.871) and you can correspondingly low of the state category: (? = 0.824).

Therefore, the internal consistency reliability of the RS-14 is not only acceptable across all sample populations, but also rather robust. Additionally, the analysis of the discriminative power of individual items shows that all test items are positively correlated with the scale. Because of the slight variation in Cronbach’s Alpha value for items where the correlation with the scale was <0.300, it was decided to include all test items in the factor. The exact results are shown in Table 4 below.
