To develop the scale; 1. Creation of Item Pool, 2. Obtaining Expert Opinion, 3. Creation of Pre-Trial Form, 4. Factor Analysis is made. According to factor analysis; Kaiser Meyer Olkin (KMO) rate; 0.808; Bartlett test result: 2148,354; Cronbach alpha reliability coefficient for the whole scale: 0.829. According to confirmatory factor analysis: Root Mean Square Error of Approximation (RMSEA) 0.022 (<0.05); p-Value for Test of Close… Continue Reading
