Friendships are important sources of support during adolescence. However, a growing literature indicates some adolescents co-ruminate, or talk with friends about problems in a way that is excessive, speculative, and negatively focused, which confers risk for internalizing problems. Still, previous research had not examined the types of problems…

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 social-emotional (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…

Youth with greater levels of narcissism face a wide array of difficulties in interactions with others. However, there exists a curious lack of research on their close relationships, such as friendships. In this study, we examined associations between narcissism and friendship features over time. Participants were 261 eighth and ninth graders (112…

Past meta-analyses show that both child-mother and child-father attachment insecurity are independently and jointly associated with more externalizing behaviors in children. Little is known, however, on the ways that different types of insecure attachment independently and jointly predict the development of externalizing behaviors over time.…

Intrusive parenting has been traditionally considered a negative parenting style and includes actions that are overly directive and controlling of children's behavior. However, current research aims to contextualize this parenting behavior. This study examined the relation between intrusive parenting and early childhood behavior problems or…

Thirty-one children of gay single fathers and 28 children of heterosexual single fathers, all born through surrogacy, were compared with 31 children of gay partnered fathers through surrogacy and 30 children of heterosexual partnered fathers through in-vitro fertilization on their perceptions of self-worth and their father- and caregiver-reported…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

To elucidate the processes underlying the cultural construction of adolescence, this research examined youth's stereotypes about teens in Hong Kong and Chongqing, a relatively less developed city in Mainland China. Youth (N = 1,269) reported on their teen stereotypes and problem behavior in the fall and spring of 7th grade. Youth in Hong Kong (vs.…

This research highlights the critical role of gender in the context of problem talk and social support in adolescents' friendships. Early- and middle-adolescents' (N = 314 friend dyads; Ms = 13.01 and 16.03 years) conversations about problems were studied using observation and a short-term longitudinal design. Mean-level gender differences emerged…

Research demonstrates that parents' emotion-related discourse during reminiscing shapes children's psychosocial outcomes, yet little is known about how different forms of parental emotion-related discourse work in combination. The present study takes a person-centered approach to better understand the relation of multiple forms of parental emotion…

The Socialization of Emotion (Eisenberg, Cumberland, & Spinrad, 1998; Eisenberg, Spinrad, & Cumberland, 1998) model creates a theoretical framework for understanding parents' direct and indirect influences on children's emotional development, including the influence of parent characteristics on subsequent emotion specific parenting. Large…

Clinically meaningful behavior problems are thought to be present beginning in the early toddler years, yet few studies have investigated correlates of behavior problems assessed before age 2 years. The current study investigated the direct and interactive contributions of early infant and caregiver characteristics thought to play an important…

Decision-making impairments during emerging adulthood confer risk for challenges in social and occupational roles and may increase the odds of developing health problems. Childhood maltreatment is related to maladaptation in cognitive and affective domains (e.g., executive functioning, emotion regulation) implicated in the development of…

This article used a sample of 2 adolescents per family to (a) examine the extent to which parental monitoring and adolescent information management are characteristics of families or of dyads and (b) replicate past research on parental monitoring and adolescent information management using models that distinguish differences between families from…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…
