During early adolescence, individuals can refine their use of cognitive reappraisal as an emotion regulation strategy while experiencing instability of psychological well-being through changes to positive affect, negative affect and life satisfaction. This scoping review aimed to identify and summarise the key findings from studies that have…

This study examined the relationship between the accuracy of parental reporting of children's sleep duration compared to objectively measured child sleep and tested whether any discrepancies were related to childhood obesity prevalence in a sample of Latinx families (N = 119). A paired sample t-test revealed that parents significantly…

Social media addiction (SMA) is considered a risk factor for aggressive behaviors in adolescents, while its underlying mechanisms remains unclear. In this study, we investigated the possible mediating roles of nighttime social media use and sleep quality in the relationship between SMA and aggressive behaviors. A sample of 773 Italian secondary…

This study investigates the role of Positive Affect as a predictor of Psychological Well-Being in 43,653 12-year-old children from 29 countries, using a Structural Equation Model. The model's potential gender and nationality equivalences were also examined. Data was sourced from the International Child Well-Being Survey. The 'happy' item was found…

Friends in early adolescence play a significant role in students' lives, potentially influencing their academic performance. A multi-group stochastic actor-oriented model was employed to examine the effects of social selection and peer influence through friendship ties on Czech language grades and reading literacy among lower-secondary students,…

Research has established the significance of social achievement goals in shaping adolescents' academic engagement. However, the precise mechanisms underpinning this connection remain incomplete. In two studies involving U.S. middle school students (Study 1 N = 212, Study 2 N = 318), we explored the relationship between social achievement goals,…

The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth…

Although adolescence is characterized by increasing individuation, parental support represents an important resource especially in early adolescence. This multi-informant study examined the role of parental self-efficacy in providing emotional and instrumental support when early adolescents partially learned from home during the COVID-19 pandemic.…

There has been concern about the potential sequelae of mild traumatic brain injury (mTBI) in children. This study used data from the Adolescent Brain Cognitive Development[superscript SM] (ABCD) study to investigate associations between mTBI and behavior and sleep in school-aged children. Generalized additive mixed models were run to examine the…

Although cyber victimization has been suggested as a significant risk factor for the development of adolescents' depression, the underlying psychopathological process that mediates this relationship needs further exploration. Based on the psychological inflexibility model, this study aimed to examine cognitive fusion and experiential avoidance as…

Identity research focuses on multiple processes capturing how adolescents form and maintain a sense of self. However, identity content (the "what" of identity) might impact associations between identity and the association with well-being. We examined this potential role of content (i.e., valence and life domain) in two studies, focusing…

The goal of this study was to advance the conceptualization and measurement of adolescent popularity by exploring the commonly used composite score (popularity minus unpopularity). We used standardized peer nominations from 4,414 early adolescents (ages [approximately equal to] 12-14 years) from three samples collected in two countries. Popularity…

The main aim of this study was to investigate a conceptual model linking subtypes of social withdrawal, social/asocial dissatisfaction, and internalizing problems in late childhood and early adolescence. Participants were N = 459 students (n = 247 girls) aged 8-14 years (M = 11.24, SD = 1.66), who completed self-reports assessments of social…

Perfectionism is a multidimensional personality trait whose facets differentially relate to indicators of psychological functioning, such as global self-esteem. There has been some theoretical disagreement whether perfectionism affects global self-esteem, or vice versa. This question merits renewed attention due to increasing efforts to prevent…

This study using PROSPER data (N = 977, age 11.5-age 15) investigated the longitudinal within-family associations between parent reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between…
