Objective: Adolescents and young adults are at risk for non-suicidal self-injury (NSSI) and suicidal behavior.

Method:…

This 1-year longitudinal study examined the moderating effect of perceived parental social support in the associations between homophobic cyberbullying involvement (victimization and bystanding) and suicidal ideation, non-suicidal self-harm, and subjective health complaints among 467 adolescents (M[subscript age] = 13.81 years; 59% female) who…

The present study investigated the role of parenting stress in early adolescents' externalizing and internalizing behavior and, particularly, the moderating effect of maternal affection on these associations. The data of 992 early adolescents (x-bar[subscript age]=12.71; 454 girls) and their mothers during the transition from primary school to…

This study investigated interactions between parents and 12-month-old infants at high (HR-SIBS; n = 27) and low (LR-SIBS; n = 14) familial risk for autism spectrum disorder (ASD). The contributions of parental variables, as well as child's autism symptom severity and verbal skills, to the parent interaction style were examined. Parents of HR-SIBS…

The purpose of this study was to provide descriptive and qualitative information about problem behaviours in children with fragile X syndrome (FXS) and how families respond to these…

Physiological synchrony, or concordance, among caregiver-child dyads involves the matching of biological states. Understanding this process is critical for enhancing our knowledge of the ways that the caregiver-child relationship supports child development. However, the meaning of physiological synchrony for child adjustment is poorly understood.…

Individuals with intellectual and developmental disabilities (IDD) are at a high risk for engaging in self-injurious behavior (SIB). Prognosis is poor when SIB emerges early. Limited research exists on interventions teaching parents how to manage their young child's SIB. This investigation assessed the feasibility of adapting an applied behavior…

Non-suicidal self-injury (NSSI) is a significant international mental health concern, with consequences for not only youth who self-injure, but for their entire family system.

Perfectionism is always not pleasurable, and people typically confuse their talents and capabilities with their perfectionism. In fact, perfectionism interferes with a person's ability to do well (Hummel, 2000). This paper…

The COVID Social Mobility & Opportunities (COSMO) study is a new national cohort study generating high-quality evidence about how the COVID-19 pandemic has affected socio-economic inequalities in life chances, both in terms of short- and long-term effects on education, wellbeing, and career outcomes. A representative sample of young people in…

Behavioural adjustment is critical for children's school readiness. This study used data from a nationally representative sample of children from the Early Childhood Longitudinal Study-Birth Cohort. We examined the effects of interactions between children's negative emotionality, maternal sensitivity and preschool teacher sensitivity on children's…
