Adult playfulness helps children to reduce their negative feelings and go through more smooth transitions for new experiences, and this propounds the importance of examining the playfulness of teachers. The aim of this study is to examine the psychometric properties of Adult Playfulness Trait Scale (APTS)-Turkish Form in terms of teacher candidates. The study was conducted with 440 university students. Explanatory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to test the validity of the scale and alpha value was calculated to test the reliability of the scale. Factor loadings and fit indices indicated that the construct validity of scale was high. Consequently, construct validity and reliability of scale were found to be high level.
