Table step one shows the essential detailed statistics towards the analyzed factors together with IDI (Product Challenge Index) value

It was not seen that the delivery out-of examined points differed somewhat on the typical delivery. Simultaneously, IDI list failed to show the current presence of floors otherwise ceiling effects throughout the investigation (only regarding goods nine “We keep selecting anything” performed hook threshold effect reveal for all around three samples). Regularity analysis for personal sample products demonstrated no troubles with study granulation. Due to that, most of the issues was utilized in then analyses. It due to response place prejudice, such public desirability and you can acquiescence.

Factorial Authenticity

By applying the Velicer MAP method kik, 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 research indicated that a one-factor solution was the most appropriate for everybody about three this new examples. As conveyed during the Dining table 2, the only-grounds design displayed good item loadings and you can similar performance had been seen concerning your items loadings across the about three samples. Most of the issues piled saliently on this subject foundation, having goods loading ranged between 0.505 and you can 0.719 during the early adulthood attempt. Throughout the kids it was ranging from 0.464 and you will 0.770 plus in the difficulty classification it had been ranging from 0.400 and you will 0.668. A decreased loadings remained tall, guaranteeing the fresh defined design of your own Polish brand of the latest appliance.

The next step provided evaluating the results of design fitting procedures from other available training. There were no high differences between the latest model fitted score gotten throughout the confirmatory grounds studies (CFA). The brand new Shine sort of RS-14 showed a defined you to-dimensional basis build which have reples.

At the same time, it needs to be noted one to about three decide to try recognition organizations zero significant variations was basically noticed. Detailed results are given for the Desk step three.

Cross-Category Legitimacy Accuracy out-of Balances

Cronbach’s alpha coefficient was utilized to examine the internal structure away from the new gotten survey symptoms. The outcomes are showed lower than.

Brand new reliability of composed grounds is 0.853 (full attempt) in the validation demonstration, and this confirms their higher consistency. Immediately following section towards the validation communities, no significant variations in size feel have been noticed. Cronbach’s alphas varied ranging from 0.824 and 0.871 over the about three examples:

The best reliability of one’s acquired grounds are from the more youthful adults (? = 0.871) and you will respectively lower of the situation group: (? = 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.
