The intervention of bystanders plays a crucial role in mitigating incidents of school bullying. The decision of bystanders to intervene is influenced by factors stemming from both individual and environmental dimensions. Individuals with strong empathetic abilities may opt for passive observation rather than proactive intervention when confronted…

Victimization by bullying is often treated as a unitary construct, although there are multiple dimensions that are likely to affect the impact of the experience for the victim. Latent class analyses were used to identify classes of victimization by (a) form of bullying (seven categorical items), (b) perceptions of motivation for victimization (15…

This study investigates how the interplay between adolescents' daily levels of emotional distress and diurnal cortisol relates to their risk-taking behaviors. Specifically, we test competing hypotheses whether emotional distress exacerbates the link between cortisol and risk taking, or whether cortisol only predicts risk taking in the absence of…

Parental stress is a well-documented phenomenon. The relationships between parental stress, parent-child dynamics, and child outcomes are complex and bidirectional. Although this intricate interaction is well recognized, we specifically examined the impact of child-related variables on parental stress. Although many child factors can contribute to…

Suicide is the second leading cause of death in adolescents (ages 12-19) in the United States, and more work is needed to shed light on the interpersonal protective factors associated with adolescent suicidality. To address this gap in the empirical literature, we examined the application of the Interpersonal Theory of Suicide (IPTS) to the middle…

Adaptability (adjustment to new and uncertain situations) and grit (perseverance and passion for long-term goals) both sustain students, but their joint contribution has never been explored, and recent studies propose they could compose a single factor. In this study we aim to test whether (1) they actually belong to a single overarching factor as…

Purpose: The current study addresses a gap in the literature regarding syntactic development of adolescent boys with fragile X syndrome (FXS) and Down syndrome (DS). Specifically, we ask whether syntactic skills plateau or continue to change during adolescence for these groups and whether the profile of syntactic change differs between boys with…

Increasing research has indicated associations between popularity goal and adolescents' social functioning. However, little is known about the processes intervening and moderating these associations. We examined whether popularity status insecurity explained the longitudinal associations of popularity goal with depression and social behavior among…

Children's early experiences have potential to shape their development through early childhood, middle childhood, and into adolescence. Family structure at birth and material hardship may offer insight into how children's health and well-being are shaped within their family of origin. The current paper examined (a) the association between family…

Autism is a lifelong condition characterized by repetitive and restrictive behaviors and differences in social communication. The reported prevalence of autism has risen exponentially in the past years. Early identification and subsequent early intervention are key to promoting better outcomes for autistic individuals. However, there is a dearth…

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…

The objective of the study was to examine how distinct psychopathic traits, including callous-unemotional (CU) traits, impulsivity and narcissism, as well as family, school and friend social support are longitudinally associated with cyberbullying and cyber-victimization. Associations were investigated by employing a four-year longitudinal design…

This study shows longitudinal predictors of involvement in different bullying roles, including mental health, individual, family, peer and school predictors. The analyses were based on a longitudinal prospective study with 916 students followed up from ages 7 to 17 with 7 waves of data. Participants were selected through random sampling and were…

Studies commonly measure the challenges of caring for autistic adolescents and young adults, but scarcely explore the positive aspects of the caregiving experience. This study employed an equal-status concurrent mixed methods approach to quantitatively assess predictors of positive aspects of caregiving and qualitatively examine 174 caregivers'…

Background: Robust research indicates that social support is negatively associated with depression and anxiety. Less work has investigated social support as a network of support across sources like parents and classmates. Past work suggests that sources of support have differential associations with internalizing outcomes. More work exploring the…
