It was not seen that delivery of analyzed points differed significantly on normal shipping. On top of that, IDI directory don’t confirm the presence of flooring or threshold effects on investigation (only in the example of item nine “We remain wanting some thing” did hook threshold perception show for everyone about three samples). Frequency studies getting personal decide to try affairs showed no troubles which have research granulation. Due to that, the things were used in then analyses. Then it due to effect set bias, like public desirability and you will acquiescence.
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 research revealed that a-one-basis solution are the most likely for everybody three the newest products. Since the conveyed when you look at the Dining table 2, the main one-grounds model exhibited a great items loadings and you will comparable abilities was basically seen regarding the goods loadings along side about three products. All of the points loaded saliently on this factor, which have product loading varied ranging from 0.505 and you will 0.719 during the early adulthood decide to try. Throughout the kids it absolutely was ranging from 0.464 and 0.770 plus in the difficulty group it absolutely was anywhere between 0.eight hundred and you will 0.668. A decreased loadings were still significant, confirming the fresh defined structure of your Polish kind of the brand new instrument.
The next thing integrated comparing the outcomes of the design installing strategies off their offered studies. There had been zero significant differences when considering the model fitted score obtained regarding confirmatory factor investigation (CFA). Brand new Shine particular RS-14 showed a coherent one-dimensional grounds framework with reples.
While doing so, it ought to be listed one regarding the around three try recognition organizations zero major variations have been seen. Detail by detail results are given when you look at the Desk 3.
Cross-Group Validity Reliability of Balances
Cronbach’s leader coefficient was applied to examine the interior feel out of new gotten questionnaire indicators. The results try displayed below.
The brand new precision of the written foundation is 0.853 (full test) from the recognition trial, and that confirms its highest structure. Shortly after division with the recognition communities, zero extreme differences in scale feel have been noticed. Cronbach’s alphas ranged ranging from 0.824 and you may 0.871 over the about three samples:
The greatest precision of the acquired foundation try from the young grownups mousemingle ekÅŸi (? = 0.871) and correspondingly lowest because of the problem 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.
