Sažetak
Collection of 43 items of attitudes toward Judo evaluated on a five-point scale were given to sample of 209 subjects students (135 males and 74 females) students of Kinesiology who completed regular Judo course prescribed by a curriculum. Centroid method of clustering was applied on this collection of items to obtain two preliminary twenty item forms. In the next step, sixteen highest positive principal loadings of each of forms were selected for two alternate forms of scale of attitudes toward judo. Basic psychometric analysis of metric properties of composite measurement for two alternate forms was done, along with confirmatory factor analyses performed on subscales as composite score indicators pertaining to each of the two forms. Measurement models were specified following the basic assumptions of classical test theory so that the models of parallel, tau-equivalent and congeneric tests could directly be compared and evaluated. The analyses proved that the most restrictive model, i.e., that of parallel tests provided excellent fit to the data. Likewise, on a descriptive level, the row scale scores defined as simple sums of items reflect the obvious status of the measures as parallel forms of Scale of Attitudes Toward Judo: their means were MJusumA = 61.29 and MJusumB = 61.12 and standard deviations SDJusumA = 9.93 ; SDJusumB = 9.96, with the associated student t-test of difference, t = 0.597, p>0.5. Correlation between summation scores was 0.922 and correlation between standardized principal components was 0.925. Correlations of summation scores of forms A and B with personal relation to judo used as an external criterion were 0.741 and 0.698, respectively. The presented evidence clearly shows that the two alternate forms can be used as parallel forms of Scale of Attitudes Toward Judo.
