Self-regulation for pre-school children is very important to support children’s adjustments in all situations and conditions. The current problem is the instrument of self-regulation is more focused on regulation in learning which is not suitable for young children. This study aims to examine the validity and reliability of Preschool Self-Regulation Assessment (PSRA) in Indonesia by modifying several children self-regulation theories. The instrument was translated from English into Indonesian and it retranslated into the native language by linguists. The questions, then, were validated through a process of professional judgment and cognitive de-briefing. The study was carried out to 179 children aged 6 to 7 years old. Data were analyzed by using confirmatory factor analysis (CFA). It showed that there are 5 dimensions of children's self-regulation, namely: attentional focus, behavioral control, self-motivated, self-autonomy and emotional control. The result showed that the five-dimensional model is agreed with the data and prove to measure children’s self-regulation. Cronbach’s alpha coefficient value was 0.899, indicating high scale reliability. Thus, the pre-school children’s self-regulation assessment has well psychometric for further use.
