Dining table step one shows the basic detailed analytics on assessed factors and the IDI (Item Problem List) value

It wasn’t observed your distribution off analyzed circumstances differed significantly from the regular shipping. While doing so, IDI list did not show the existence of floors otherwise ceiling consequences from the studies (only when it comes to product 9 “I keep selecting some thing” performed hook ceiling perception tell you for all around three trials). Regularity investigation to possess personal attempt items displayed no problems with study granulation. In that respect, every items was basically used in subsequent analyses. Then it on account of impulse put prejudice, particularly personal desirability and you may acquiescence.

Factorial Legitimacy


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.

Parallel analysis revealed that a one-grounds service try the most likely for all around three new trials. Because the conveyed into the Desk 2, the only-factor design presented a good product loadings and you may equivalent show was indeed noticed about your goods loadings along side around three products. Every items piled saliently about this basis, that have product loading varied anywhere between 0.505 and you can 0.719 in the early adulthood test. Throughout the adolescents it was between 0.464 and 0.770 as well as in the difficulty group it absolutely was ranging from 0.eight hundred and you can 0.668. The lowest loadings remained significant, guaranteeing the coherent framework of one’s Polish form of the fresh tool.

The next phase incorporated comparing the outcome of your design suitable measures from other offered education. There have been zero significant differences when considering new design suitable score gotten in the confirmatory basis studies (CFA). The fresh Shine sort of RS-14 showed a defined you to-dimensional basis design which have reples.

At the same time, it ought to be detailed you to in the three decide to try validation organizations zero biggest distinctions was indeed seen. Outlined answers are offered from inside the Table 3.

Cross-Category Validity Accuracy regarding Scales

Cronbach’s leader coefficient was applied to look at the internal texture from the newest gotten questionnaire evidence. The results try presented less than.

The newest precision of one’s composed basis was 0.853 (full take to) throughout the recognition demo, and that verifies its highest texture. After department towards validation organizations, zero significant differences in measure structure was basically noticed. Cronbach’s alphas varied between 0.824 and you will 0.871 along the about three examples:

The best accuracy of gotten factor was by the younger people (? = 0.871) and correspondingly low of the condition classification: (? = 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.
