Socioemotional skills between 12 and 30 months of age on Chilean children: When do the competences of adults matter?

Due to the rapid growth in early socioemotional skills during the first three years of life, significant variations in socioemotional development begin early and increase with time. Family competences as sensitivity and mentalization, contribute to differences among children of the same age. This study examines whether the level of socioemotional skills is stable or changes between 12 and 30 months of age, and whether primary caregiver sensitivity and mentalization, as well as educational level, are associated with changes in the level of socioemotional skills. One hundred and three Chilean children were evaluated. The results showed a significant change in socioemotional level between 12 and 30 months. Primary caregivers' sensitivity was associated with socioemotional skills at 12 months of age, and caregivers' educational levels was the strongest predictor. At 30 months, caregivers' sensitivity and educational level did not contribute additional influence, and only child socioemotional skills reported at 12 months acted as a predictor. Results indicate that family competences contribute to infants' socioemotional development in the first year of life, which subsequently influences their later skills.
