IRAKSAK DÜŞÜNME ÖZ DEĞERLENDİRME ÖLÇEĞİ’NİN GELİŞTİRİLMESİ
The aim of this study is to develop a scale for determining the divergent thinking self-assessment levels of adults over 18 years of age. In line with the aim of the present study, a 28-item-trial form was applied to the participants. Exploratory f actor analysis based on the method of oblique rotation revealed that the scale had a 21-item and two-factor components structure. Sub-dimensions are entitled as rationality and subjectivity. The eigenvalue of the rationality sub-dimension was found to be 6.90. The eigenvalue of the subjectivity sub-dimension was found to be 3.94. The total variance of the two-factor structure was found to be about 50.66%. The Cronbach coefficient score for the whole scale was .91. The Cronbach coefficient reliability scores for the sub-scales of rationality and subjectivity were .92 and .85, respectively. Moreover, item correlation coefficients were above .50 for all the items of the form. Consequently, validity and reliability analysis indicate that the final form can measure the levels of divergent thinking self-assessment of the participants
