Summary or Abstract : Previous research has noted the link between temperament and psychopathology. However, there is a relative lack of research during the earliest years of life (i.e. infancy) that examines factors impacting temperament development toward increased risk for psychopathology as well as research examining models of psychopathology with the inclusion of temperament. The purpose of the current investigation is to address these limitations by examining (1) predictors (maternal depression, negative affect, parenting stress) of growth trajectories of infant positive emotionality/affect (PA), negative emotionality/affect (NA), and regulatory capacity from 4 to 12 months of age and (2) to examine the role of temperament measured in the first year of life (8 and 12 months of age) on toddler externalizing and internalizing difficulties at age 24 months in the context of other known risk factors of behavioral problems (i.e. maternal depression, anxiety, parenting stress, negative parenting, and negative affect). One-hundred fifty-eight families from WA, OR, ID, MT, and NV with a 4-month old infant agreed to participate in this 20 month long investigation. Analyses utilized latent growth modeling (LGM; Study 1) and structural equation modeling (SEM; Study 2). Results of the first study identified normative developmental patterns of infant PA, NA, and regulatory capacity in the first year of life and implicated maternal depression and stress in interindividual differences in PA and NA growth trajectories. Findings in Study 2 indicated the direct effect of lower 12 month infant regulatory capacity on increased externalizing and internalizing difficulties. Furthermore, analyses suggest that the impact of infant NA on internalizing and externalizing difficulties is partially mediated through regulatory capacity and that the effect of infant PA on externalizing and internalizing difficulties is fully mediated through regulatory capacity. Additional findings are discussed as well as implications for future research. models of early emerging psychopathology, and early prevention and intervention efforts..
