Objective: Previous studies have linked ADHD with self-harm, but the processes underlying this association are not fully understood. This research aims to investigate the role of sleep disturbances as a potential pathway between ADHD diagnosis and self-harm behaviors. Materials and Methods: The study included 90 youth aged between 11 and 18 years,…

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…

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.…

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…

Maternal depressive symptoms predict negative child behaviors, including internalizing problems. However, protective factors, such as positive emotionality and positive parenting behaviors, may play an important a role in attenuating associations between maternal depressive symptoms and child behavior problems. This article presents two studies…

Concerns regarding the social-behavioral maladjustment of U.S. youth have spurred efforts among educators and policymakers to identify and remedy educational contexts that exacerbate children's anxiety, depression, aggression, and misconduct. However, investigations of the influence of collective classroom student characteristics on individuals'…

Nonsuicidal self-injury (NSSI) is a serious public health problem. Identifying the factors that could help prevent or reduce NSSI is important. The current study examined the protective roles of the perceived qualities of current attachment to significant others (i.e., mothers, fathers, and peers) and self-compassion in adolescent NSSI. The…

Background: Challenging behaviours are frequently shown by children with an intellectual disability. This study documents service use within this population and explores its relationship with challenging behaviours and child and parent characteristics.Method Forty-nine mothers of young children with an intellectual disability or global…

In the present study, we examined the extent to which the responses of teachers and mothers toward a particular child are similar in respect to their instructional support and affect, and whether child characteristics predict these responses. The data of 373 Finnish child-teacher-mother triads (178 girls, 195 boys) were analysed. Teachers and…

The purpose of this study was to evaluate the effects of functional communication training (FCT) on the occurrence of non-targeted disruptive behavior. The 10 participants were preschool-aged children with developmental disabilities who engaged in both destructive (property destruction, aggression, self-injury) and disruptive (hand flapping,…

Mothers' attributions of self injurious behaviour (SIB) in their children with intellectual disability have been largely ignored. However, attributions may predict maternal well-being and engagement in treatment. Thirteen mothers of people who self-injured were recruited. A qualitative design was employed, the data being subjected to thematic…

A paucity of research exists examining personality and cognitive characteristics that may contribute to nonsuicidal self-injury (NSSI). The purpose of the current study was to clarify the contribution of perfectionism and rumination, along with depression and anxiety, to NSSI within a sample of 170 college students. Group comparisons revealed that…

We tested predictions generated from an evolutionary account of self-destructive motivation in two survey studies of 18-24-year-old university students. As hypothesized, hierarchical regressions showed that the positive relationship between perceived burden to family and suicide ideation was amplified for participants with low measured health and…

Background: Family process variables have been linked to child problem behavior, but recent research suggests that child ethnicity may moderate relations between family process and child outcomes. The current study examined how ethnicity moderates relations between parent conflict, parent-child relationship quality, and internalizing problems.…

A mental health clinic was developed for toddlers with developmental disabilities and significant behavior problems from families living in poverty. The clinic was a collaborative effort between a community-based Birth-to-Three agency and a university. The purpose of this clinic was threefold: to provide direct mental health services for these…
