Bullying carries great harm for all involved, undermining academic achievement as well. The strength of such impact is yet to be clarified, existing many possibilities and variables to analyze -- classroom behavior being one. The present cross-sectional investigation goal was to study the impact of bullying (mediated by the classroom behavior) on…

Background: Cigarette use is a public health issue and juvenile offenders are at risk for engagement in substance use. Attention deficit hyperactivity disorder (ADHD) has been linked to elevated risk for cigarette use and juvenile offenders are at elevated risk for mental health issues. Objectives: To elucidate general patterns of development of…

The objective of this study was to analyse the relations between the function of openness to the world, family functioning and child behaviour. In order to do that, a quantitative research was conducted with 171 biparental families from the South Region of Brazil, with children from four to six years of age. Two association hypotheses were…

Educators and education researchers in postsecondary physics have rarely centered (i.e., intentionally directed attention to) the experiences of students with disabilities, leading to an instructional environment that is not designed to support students with disabilities. In this study, we interviewed five students who identified with the…

Youth with ADHD are more at-risk for peer victimization than their typically developing peers, and may not be benefiting from current interventions. Thus, we sought to examine risk (i.e., anxiety, depression, and forms of aggression) and protective (i.e., social skills and social acceptance) factors for peer victimization in this group.…

To advance the research examining the sluggish cognitive tempo (SCT) construct, a key priority has been to develop assessment tools that are reliable and valid. The current study builds upon existing work by conducting the most thorough psychometric evaluation to date of the teacher-reported Child and Adolescent Behavior Inventory (CABI) SCT and…

Adolescence is a developmental period that affords both risk as well as enormous opportunity. Ripple effects can extend far and wide and speak to the nuance and complexity in understanding and treating ADHD during the adolescent period. The studies in this special issue provide novel and important insights into the lives of adolescents with ADHD,…

The present study evaluates differences in self-reported intrinsic and extrinsic academic motivation and amotivation between eighth-grade adolescents with (n = 162) and without (n = 140) ADHD. This study also examines associations between motivation and academic functioning with objective (i.e., grade point average, standardized reading and math…

While topics like socioeconomics, race, gender, veterans, transfer students, and other underserved populations frequently grab headlines, another student category often gets left out of the conversation about diversity. Society typically labels students with neurological differences--which can include dyslexia, attention deficit hyperactivity…

Students with ADHD struggle substantially at the post-secondary transition. Yet, no empirical work identifies school-based intervention targets that specifically prepare graduating students for adjustment to this new phase of life. This study is a preliminary investigation of factors that promote success for students with ADHD during the…

Researchers have begun to inquire into the experiences of young people with ADHD, including how they define ADHD and how a diagnosis of ADHD affects them. ADHD is considered a neurodevelopmental disorder and diagnosis is frequently requested by school professionals. The purpose of this qualitative study was to examine the experiences of young…

Objective: A randomised control trial was conducted to assess whether the combined Incredible Years parent training and child training programmes (PT + CT) led to improvements in ADHD-type behaviours in children, when compared to a PT-only group and a Wait List Control (WLC) group. Method: Forty-five families with a child aged 3-7 years who…

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

The purpose of the study was to assess early literacy skills and examine the presence and stability of challenging behaviors across the critical threshold of the kindergarten school year. Students' (n = 337) literacy performance (letter sound fluency, word attack, and phonological awareness) and challenging behaviors (teacher ratings of…

The evidence-based assessment of attention-deficit/hyperactivity disorder (ADHD) depends on adherence to "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.; "DSM-5") diagnostic criteria and reliance on multi-method/multi-informant data. Although nearly all psychologists endorse these practices, college students…
