School belonging, measured as a unidimensional construct, is an important predictor of negative affective problems in adolescents, including depression and anxiety symptoms. A recent study found that one such measure, the Psychological Sense of School Membership scale, actually comprises three factors: Caring Relations, Acceptance, and Rejection.…

Temperament and attention-deficit/hyperactivity disorder (ADHD) are both typically viewed as biologically based behavioural constructs. There is substantial overlap between ADHD symptoms and specific temperamental traits, such as effortful control, especially in young children. Recent work by Martel and colleagues (2009, 2011) suggests that…

Epidemiological studies have identified recent declines in specific types of adolescent substance use. The current study examined whether these declines varied among youth with and without a history of interpersonal victimization or posttraumatic stress disorder (PTSD). Data for this study come from two distinct samples of youth (12-17 years of…

Cyberbullying among school-aged children has received increased attention in recent literature. However, no empirical evidence currently exists on whether existing school-based antibullying programs are effective in targeting the unique aspects of cyberbullying. To address this important gap, the present study investigates the unique effects of…

Recent research has demonstrated that higher levels of mindfulness are associated with greater psychological and physical health. However, the majority of this research has been conducted with adults; research is only beginning to examine the effects of mindfulness among adolescents. Further, research into adolescent mindfulness has typically…

In recent developmental theorizing, it has been hypothesized that teacher-child conflict and children's externalizing behavior affect one another reciprocally over time. However, the relation between teacher-child conflict and externalizing behavior has been mainly studied from a unidirectional point of view. Therefore, this study aimed to test…

Depression is a common psychological problem in adolescence. Recent research suggests that group cognitive-behavioral interventions can reduce and prevent symptoms of depression in youth. Few studies have tested the effectiveness of such interventions when delivered by school teachers and counselors (as opposed to research team staff). We…

Attention-deficit/hyperactivity disorder (ADHD) is a highly heterogeneous disorder, and the phenotypic structure comprising inattentive and hyperactive-impulsive type symptoms has been the focus of a growing body of recent research. Methodological studies are needed to better characterize phenotypes to advance research as well as clinical…

Among adolescents, many parenting practices have been associated with the initiation and development of drinking behaviors. However, recent studies suggest discrepancies in parents' and adolescents' perceptions of parenting and their links with adolescent use. In this study, we derive two independent sets of underlying parenting profiles (based on…

We examined the phenotypic expression of attention-deficit/hyperactivity disorder (ADHD) across cultures by assessing the factor/latent class structure of its core symptoms. We conducted a systematic review of the literature published from January 1987 to November 2008 using Medline and PsycINFO. We systematically reviewed 2,511 article abstracts,…

In view of recent findings regarding the multifaceted nature of rumination in adults and older adolescents, the purpose of this study was to evaluate the construct of rumination as a 2-factor model (brooding and reflection) in a child and early adolescent sample as well as examine sex differences and associations between depressive symptoms and…

This study examined parenting and peer predictors of physical dating violence perpetration during early adolescence and tested moderation among these predictors and gender. Participants were 2,824 ethnically diverse sixth-grade students with a recent boyfriend/girlfriend who was part of a multisite, longitudinal investigation of the development…

This study examined the role of multiple children's emotions and parental anxiety during parent-child interactions of anxiety disordered (AD) and nonanxious (NA) children ages 7 to 13 years. Families (mother, father, child) each discussed three recent and real separate situations in which the child experienced anxiety, anger, and happiness.…

This study examined the relations among early and recent experiences with abuse, depression, and adolescents' autobiographical memory in a longitudinal study of family violence. Participants' (N = 134) exposure to violence was documented when they were 6 to 12 years old and again when they were 12 to 18 years old. The second assessment included…

This study examined for profiles of positive trait affectivity (PA) and negative trait affectivity (NA) associated with adolescent conduct problems. Prior trait affectivity research has been relatively biased toward the assessment of adults and internalizing symptomatology. Consistent with recent developmental modeling of antisocial behavior, this…
