The aim of the study was to examine associations between life events and self-assessed loneliness in adolescence. We used data from a Norwegian population-based twin sample including seven birth cohorts (N = 2,879, 56% females). The participants completed self-report questionnaires three times throughout adolescence, with 2 years in between (i.e.,…

Two studies examined the process and aftermath of coming to disbelieve in the myth of Santa Claus. In Study 1, 48 children ages 6-15 answered questions about how they discovered Santa was not real and how the discovery made them feel, and 44 of their parents shared their perspectives and how they promoted Santa. In Study 2, 383 adults reflected on…

Family systems research has identified two key processes (spillover and compensatory), linking interparental relationship quality to the parent-child relationship. However, previous research has focused on the parent as the sole initiator and had not often considered the role of the child in these processes. The present study adds to the…

Food insecurity poses a serious threat to children's development, but the mechanisms through which food insecurity undermines child development are far less clear. Specifically, food insecurity may influence children through its effect on parents' psychological well-being and parent--child interactions as a result, but past research on the role of…

This study examined the relations between normative developmental changes of familism values and later internalizing and externalizing behaviors in Latinx adolescents from an emerging immigrant community. The sample included 547 Latinx adolescents (55.4% female; baseline M[subscript age] = 12.80; SD = 1.03) residing in the Southeastern United…

Adolescence and young adulthood are characterized by substantial sociodemographic, family, social, and personality changes that may influence loneliness. Although loneliness is a public health challenge, we know little about how loneliness develops during these periods. Our study addresses this lacuna by using 4-wave longitudinal data from 3,116…

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…

Research has only recently begun to examine how callous-unemotional (CU) traits interact with contextual factors to predict delinquent behavior. The current study attempts to explain the well-established link between CU traits and offending by testing the potential mediating and moderating roles of 2 critical contextual factors: peer delinquency…

For research on emotional development, defining emotions as psychological systems of appraisals, expressions, body reactions, and subjective feelings in all phases of ontogenesis raises tricky methodological issues. How can we measure single emotions when appraisals and feelings cannot be assessed from outside, when expressions do not seem to be…

We examined within- and between-person variations in parental legitimacy beliefs in a sample of 883 Arab refugee youth (M[subscript age] = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians, in Amman, Jordan. Latent profile analyses of 22 belief items yielded 4 profiles of youth. The "normative" profile (67% of the…

The present three-study investigation examined cultural influences on the internalization of social expectations. Testing the claim of self-determination theory that lesser internalization of social expectations is linked to socialization practices that portray social expectations as in conflict with autonomy, in Study 1 we undertook a content…

Person × Environment mismatch theory has been applied to understanding how the classroom social ecology moderates associations between peer victimization and socioemotional well-being. In 2004, Bellmore et al. applied this theory to the ethnic composition and social climate of the classroom. The current study tested whether their findings…

This article used data from 5,171 young women participating in the Australian Longitudinal Study on Women's Health, a nationally representative longitudinal cohort study, to identify longitudinal trajectory patterns of mental health across 6 surveys over 16 years of early adulthood, from age 18-23 to age 34-39. In addition, we identified both…

Maternal control is a major dimension of parenting and has different meanings, practices, and potential consequences across cultures. The present study aimed to identify and compare mothers' conceptualizations of parenting control across four cultures to reveal a more nuanced understanding regarding the meaning and practices of control: European…

A large number of studies document that children differ in the degree they are shaped by their developmental context with some being more sensitive to environmental influences than others. Multiple theories suggest that "Environmental Sensitivity" is a common trait predicting the response to negative as well as positive exposures.…
