It was not observed the delivery from reviewed points differed notably regarding the typical distribution. Additionally, IDI directory don’t establish the current presence of flooring or roof effects in the investigation (just in the case of product 9 “I remain shopping for one thing” performed a small roof effect let you know for everyone three examples). Frequency investigation for individual decide to try situations displayed no troubles with study granulation. In that respect, all of the things was basically included in then analyses. Then it due to effect lay bias, eg social desirability and you may 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.
Parallel investigation showed that a single-grounds provider is actually the most appropriate for everyone three the brand new samples. Given that indicated during the Table 2, usually the one-basis design demonstrated an excellent product loadings and you will equivalent efficiency was in fact seen regarding your item loadings along the about three products. All affairs piled saliently on this subject basis, that have items loading ranged ranging from 0.505 and you may 0.719 during the early adulthood test. Regarding the teens it was ranging from 0.464 and you can 0.770 plus the problem group it had been between 0.eight hundred and you may 0.668. A decreased loadings were still extreme, verifying the fresh defined design of your Gloss form of this new tool.
The next phase provided researching the results of model installing procedures off their offered studies. There are no extreme differences between the design fitted score obtained on the confirmatory basis analysis (CFA). New Polish version of RS-fourteen shown a coherent one to-dimensional factor construction with reples.
Simultaneously, it must be indexed one about about three take to validation communities zero major variations were observed. Outlined answers are offered within the Dining table 3.
Cross-Class Legitimacy Reliability out of Scales
Cronbach’s alpha coefficient was used to examine the internal consistency from this new acquired questionnaire signs. The results try displayed lower than.
The latest precision of written foundation is actually 0.853 (total take to) on the validation demonstration, which verifies the higher texture. After division towards recognition communities, no tall variations in level structure have been observed. Cronbach’s alphas ranged ranging from 0.824 and you will 0.871 along the around three samples:
The highest precision of the received grounds are by younger adults (? = 0.871) and you can correspondingly reasonable of the disease 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.
