The aim of this study is to conduct the validity and reliability studies of the Preschool Self-Regulation Assessment (PSRA) in Turkey. The study was carried out with 233 children, aging between 48-72 months. First of all, the scale was translated from the source language, and then translated back to the source language by experts and the texts were checked for consistency. The tasks in the scale were then reviewed by domain experts. Scoring was conducted simultaneously by the researcher and an expert to ensure assessor reliability. Analyses showed the scale had a two-factor construct, which explained 52% of the total variance. Overall reliability coefficient (a) was 0.83 while the reliability coefficients for Attention/Impulse Control and Positive Emotion sub-dimensions were 0.88 and 0.80, respectively. Test-retest reliability correlation coefficient was 0.86. These results show that the PSRA is a valid and reliable tool for evaluating the self-regulatory skills of children in Turkey.
