The second year of life is a time of formative developmental change as basic behavioral systems undergo rapid integration and expansion. This study examined the developmental trajectories of socialemotional (SoE) outcomes and the effects of infant sex and household chaos (HC) on the development of SoE outcomes across the second year of life. The participating families (N = 143) were ethnically homogenous (88% Caucasian) but economically diverse (31% low-to-very-low income). Mothers reported on their children's SoE outcomes including externalizing, internalizing, dysregulating problem behaviors as well as SoE competence when infants (54% girls) were 12, 18, and 24 months old. At each age point, HC was assessed through observations during home visits and compliance to the study protocols. Multilevel modeling revealed increasing developmental trajectories in all of the domains of SoE outcomes across the second year of life, reflecting the premise that these behavioral systems continue to form and become increasingly part of the infant's behavioral repertoire as development unfolds. However, compared to infants in less chaotic homes, infants in more chaotic households experienced steeper increases in both externalizing and internalizing problem behaviors across the second year, and girls showed higher levels of internalizing problem behaviors compared to boys. Results emphasize the increasing trajectories of problem behaviors in relation to ongoing chaotic caregiving environment among infants as young as 2 years of age.

i at M anoa Adolescents are tasked with navigating competing priorities, including whether to marry, have children, pursue a job/career, go to college, and contribute to society. The developmental task of building expectations for the future is especially complex for Cambodian adolescents living within a society that strongly prioritizes family obligations yet increasingly provides educational and professional opportunities. The current study, guided by Seginer's (2003) future orientation model, applied latent profile analysis (LPA) to explore patterns of Cambodian adolescents' (N = 580, 64% female, M age = 15.85) future expectations across key life domains and predictors of those patterns. LPA identified four profiles: Low Expectancy (low expectations across all domains; 12%), Family Focused (high expectations to get married and have children; 31%), Professional/Service Focused (high expectations across education, employment, and societal contribution domains; 27%), and High Expectancy (high expectations across all domains; 30%). Females were more likely than males to be in the Professional/Service Focused than High Expectancy profile. Adolescents with greater internal locus of control and family obligation were less likely to be in the Low Expectancy and Family Focused than High Expectancy profile, whereas adolescents in higher grade levels were more likely to be in the Family Focused than High Expectancy profile. Adolescents with closer relationships with mothers were less likely to be in the Professional/Service Focused than High Expectancy profile; adolescents with closer relationships with fathers were more likely to be in the Professional/Service Focused than High and Low Expectancy profiles. Findings elucidate configurations of adolescents' future expectations, and factors distinguishing among adolescents with different configurations.
