Stability of child temperament: Multiple moderation by child and mother characteristics

This 3‐wave longitudinal study focuses on stability of child temperament from 3 to 6 years and considers child age, gender, birth order, and term status as well as mother age, education, anxiety, and depression as moderators of stability. Mothers of approximately 10,000 children participating in the Avon Longitudinal Study of Parents and Children rated child temperament. Stability coefficients for child temperament scales were medium to large, and stability was generally robust across moderators except child gender and birth order and mother age and education, which had small moderating effects on reports of stability of child temperament. Statement of contribution What is already known on this subject? Some is known about the stability of temperament in infancy in small samples, but much less is known about the stability of temperament in early childhood or its moderation. What does this study add? This study uses a large sample (˜10,000) to trace the stability of temperament from 3 to 6 years in three waves and considers child age, gender, birth order, and term status as well as mother age, education, anxiety, and depression as moderators of stability.
