Abstract:
This study examined the test-retest reliability and predictive validity of the East Asia-Pacific Early Child Development Scales (EAP-ECDS) Short Form. In China, preschools typically provide children with educational activities in age-segregated classrooms - Kindergarten Level 1 (K1) (3 to 4 years), Kindergarten Level 2 (K2) (4 to 5 years), and Kindergarten Level 3 (K3) (5 to 6 years). A total of 709 children in K2 (Mage = 57.85 months, SD = 4.77) were randomly selected from 29 kindergartens in Shanghai municipality and Guizhou province of China. Children were assessed using the EAP-ECDS in K2 and K3. School readiness was assessed in K3, and literacy and mathematics achievement were assessed in Grade 2. Pearson's correlation coefficient and intraclass correlation coefficient (ICC = 0.73) indicated that the tool had good test-retest reliability across K2 and K3. Regarding predictive validity, K2 EAP-ECDS predicted K3 school readiness (β = 0.26), Grade 2 language and literacy (β = 0.18) and mathematics (β = 0.22) after adjusting for age, gender, socioeconomic status, and region. Findings support using the tool to measure the holistic development of preschool-aged children in China and the region.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
