형제·자매관계에 따른 아동의 사회적 능력

This study examined differences in children's social competence by number, birth order, and sibling relation types. The subjects were 489 three- to five-year old boys and girls enrolled in 4 kindergartens in Seoul and Gyeonggi Province. Instruments were the California Preschool Social Competency Scale and a questionnaire for the home environmental variables. Data were analyzed by ANCOVA, Tukey test and Cronbach ${\alpha}$. The major findings were that siblings' social competence was higher than only children, first-born children's social competence was higher than the later born, and older brother's social competence was higher than younger brothers and sisters.
