The content validity was analyzed by applying Aiken assisted by Microsoft Excel, the construct validity by using second-order Confirmatory Factor Analysis assisted by Lisrel, and the reliability by using the Omega reliability approach. The results indicate that all items are valid by which the content validity. The construct validity with the Confirmatory Factor Analysis is high. The reliability values of the observation instruments are reliable.
