Abstract:
ABSTRACT: This study used a person-centered approach to examine the development of child temperament from infancy to toddlerhood. Data from a prospective adoption study, the Early Growth and Development Study (EGDS), was used to estimate latent profiles of child temperament at 9, 18, and 27 months. Results indicated four profiles of temperament best fit the data at 9 months; High Reactive, Low Reactive, Positive Reactive, and Negative Reactive. Three profiles best fit the data at 18 and 27 months; Positive Reactive, Negative Reactive, and Fearful. The structure and characterization of profiles was stable over time. Child membership in profiles was also relatively stable from infancy to toddlerhood. Facets of adoptive parent temperament, specifically levels of harm avoidance, robustly predicted child profile membership at 9, 18, and 27 months. Birth mother temperament was also associated with child profile membership, which indicates specific genetic influences on temperament development. How study results replicate and extend prior findings from temperament literature is discussed.
