Discrepancies in first- (M = 14.97 years, SD = 1.82) and second-born adolescents' (M = 12.20 years, SD = 1.90 years) and their parents' perceptions of parental authority legitimacy (PAL) were examined in a longitudinal sample of 145 predominantly White, middle-class, U.S. families. Utilizing a growth curve modeling approach, changes in the…

The aim of this study was to examine trajectories of pathological video game symptoms over a 6-year period from adolescence to emerging adulthood. We also examined a number of predictors and outcomes for different trajectories. Participants included 385 adolescents (M age = 15.01 at the initial time point) who completed multiple questionnaires…

We tested a culturally integrative model examining the associations among economic hardship during infancy and Latino children's later sociobehavioral problems and academic skills prior to kindergarten entry, whether mothers' mental health problems and positive parenting behaviors mediated those associations, and whether they varied by mothers'…

Although social difficulties have been identified as sequelae of children's experiences with interparental conflict and insecurity, little is known about the specific mechanisms underlying their vulnerability to social problems. Guided by emotional security theory, this study tested the hypothesis that children's emotional insecurity mediates…

An approach-avoidance model of social withdrawal (Asendorpf, 1990) identifies 3 types of social withdrawal including shyness, unsociability, and avoidance. Each appears to be uniquely associated with varying indicators of maladjustment in emerging adulthood (Nelson, 2013) but little, if any, work has been done to see how they might be linked to…

Children who are iron deficient (ID) or iron-deficient anemic (IDA) have been shown to seek and receive less stimulation from their caregivers, contributing to "functional isolation". Over time, the reduced interactions between child and caregiver are thought to interfere with the acquisition of normative social competencies and…

University/college can be a challenging time as students face developmental tasks such as building new social networks and achieving academically. Social anxiety may be disadvantageous in this setting given that social situations often include drinking and individuals with social anxiety tend to self-medicate through alcohol use. However, findings…

Co-rumination is a dyadic process between relationship partners that refers to excessively discussing problems, rehashing problems, speculating about problems, mutual encouragement of problem talk, and dwelling on negative affect. Although studies have addressed youths' "tendency" to co-ruminate, little is known about the nature of…

Investigating heterogeneity in antisocial behavior early in life is essential for understanding the etiology, development, prognosis, and treatment of these problems. Data from the longitudinal National Institute of Child Health and Development (NICHD) study of Early Child Care were used to identify homogeneous groups of young antisocial children…

The identification of developmentally specific windows at which key predictors of adolescent substance use are most influential is a crucial task for informing the design of appropriately targeted substance use prevention and intervention programs. The current study examined effects of conduct problems and depressive symptomatology on changes in…

Guided by a risk and resilience framework, the current study examined the associations between Latino adolescents' ("n" = 219; "M" [subscript age] = 14.35; "SD" = 1.75) perceptions of ethnic discrimination in multiple settings (e.g., online, school) and several domains of adjustment (e.g., mental health, academic),…
