MEASUREMENT AND EVALUATION IN COUNSELING AND DEVELOPMENT, 2026 (SSCI, Scopus)
Developing self-regulation in early childhood is critical for later development, making the accurate and reliable measurement of this construct essential. This study conducted a reliability generalization (RG) meta-analysis of the Preschool Self-Regulation Assessment (PSRA) following REGEMA guidelines. A total of 35 studies reporting coefficient alpha for the Attention/Impulse Control (AIC) subscale and 12 studies for the Positive Emotion (PE) subscale were included. Bonett's transformation was applied to normalize alpha coefficients for AIC, and random-effects meta-analyses using restricted maximum likelihood estimation were conducted. Results indicated high mean reliability of the scores for AIC (alpha = 0.903, 95% CI [0.885-0.919]) and acceptable reliability of the scores for PE (alpha = 0.779, 95% CI [0.719-0.840]). Moderator analyses showed that larger sample sizes, kindergarten samples, and test administration methods were associated with higher reliability estimates. Overall, findings provide strong evidence for the generalizability of PSRA reliability across diverse samples and contexts.
