Dining table step 1 shows the essential detailed analytics with the analyzed activities and IDI (Items Complications List) well worth

It was not observed that distribution out-of analyzed situations differed somewhat in the normal shipments. On the other hand, IDI directory don’t confirm the current presence of floor otherwise roof effects in the studies (merely when it comes to items 9 “I remain looking some thing” did a little threshold impression inform you for all about three examples). Frequency investigation to have private try facts demonstrated no problems which have studies granulation. In that respect, all the items were found in next analyses. It because of effect set bias, such as for example public 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 showed that a-one-grounds services was the best for all around three the brand new examples. Since shown when you look at the Table 2, one-grounds model displayed a beneficial product loadings and you will equivalent results was basically seen regarding the goods loadings along the around three samples. Every things loaded saliently with this foundation, with item packing varied between 0.505 and you may 0.719 in early adulthood decide to try. On the kids it absolutely was ranging from 0.464 and you can 0.770 plus in the difficulty classification it actually was ranging from 0.400 and 0.668. A low loadings were still tall, guaranteeing the brand new defined framework of the Polish types of new instrument.

The next step included comparing the results of your model installing procedures off their readily available knowledge. There had been zero tall differences when considering the brand new design fitted scores obtained about confirmatory grounds study (CFA). The latest Shine types of RS-14 demonstrated a coherent that-dimensional grounds framework that have reples.

As well, it should be listed one throughout the around three sample recognition organizations no major variations was indeed observed. Intricate answers are given from inside the Desk step three.

Cross-Classification Authenticity Accuracy of Scales

Cronbach’s alpha coefficient was utilized to look at the inner texture out-of the fresh new obtained survey indicators. The outcomes is actually exhibited below.

The newest precision of the composed grounds try 0.853 (total decide to try) throughout the recognition demo, and that verifies the highest feel. Immediately following office with the validation organizations, zero tall variations in scale texture was basically seen. Cronbach’s alphas ranged between 0.824 and you can 0.871 along the three samples:

The greatest reliability of your acquired grounds is by young people (? = 0.871) and you can correspondingly low of the situation 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.
