Background: Morphological awareness plays a crucial role in supporting higher-level text processing. We examined its contribution to reading comprehension in children of different ages and ability levels in order to determine when and for whom morphological awareness is of particular importance. Methods: Three groups of children (aged 6-8 years, N…

Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two…

Conducting Youth Participatory Action Research (YPAR) is more than a methodology; it is an epistemology--a way of positioning adolescents as agents for critical civic praxis. Educators attempting to use YPAR in traditional spaces often must navigate tensions between this type of critical pedagogy and systems that limit the definition of…

Intelligence quotient (IQ), has been found to relate to the presence of internalising symptoms in autism spectrum disorder (ASD). This meta-analysis sought to clarify the direction of the relationship between IQ and two prevalent internalising symptoms, anxiety and depression, in adolescents with ASD. Secondly, this study aimed to highlight…

Background: There is extremely limited population-based research on social (pragmatic) communication disorder (SCD). Population-based samples have the potential to better characterize the SCD phenotype by mitigating confounds and biases that are typical of convenience and clinical samples. Aims: The aims of this preliminary epidemiologic study…

Research has shown that anxiety in adolescents has a negative impact on a wide range of psychosocial variables, including academic performance. This study explored the role of parental emotional expressivity during conflict interactions with their children as a potential moderator of the relationship between anxiety symptomatology and academic…

Developmental researchers commonly utilize multilevel models (MLMs) to describe and predict individual differences in change over time. In such growth model applications, researchers have been widely encouraged to supplement reporting of statistical significance with measures of effect size, such as R-squareds ("R[superscript 2]") that…

Perceived social support can help immigrant youth to deal with developmental acculturation: the simultaneous resolution of developmental and acculturative tasks. This person-oriented three-wave comparative study investigated perceived social support trajectories in two immigrant and one non-immigrant group. We investigated whether similar social…

The present research investigated personality profiles in early and middle adolescents (N = 168) and compared the emerged profiles by creative ideation, motivational autonomy, and self-efficacy in self-regulation. Cluster analyses revealed three profiles: Resilients, Flexibles, and Averages. The personality types described in the literature were…

Parent training programs focus on parent knowledge and/or skill development regarding strategies to improve child outcomes. Parent training programs are considered evidenced-based treatments for autism spectrum disorder (ASD). Yet little is known about parent training use for youth with ASD served in community settings. This mixed methods project…

Literature has documented inflated rates of features associated with autism spectrum (AS) in clinic referred, gender diverse young people. This study examined scores on the Social Responsiveness Scale, Second Edition (SRS-2) over time in a group of clinic referred, gender diverse adolescents accessing gonadotropin-releasing hormone analogues…

Transphobic bullying is prevalent in schools around the world. The present study examined the bidirectional relationships among transphobic attitudes, perpetration of transphobic bullying, and witnessing transphobic bullying. The study also included the validation of an instrument to measure transphobic bullying and the prevalence rates of…

Although bullied adolescents experience elevated risk for adverse mental and physical health outcomes, some youth exhibit resilience in the face of peer victimization. Given the developmental importance of peer relationships during adolescence, much of the research examining protective factors that can mitigate bullying-related harm has focused on…

The purpose of this multi-site randomised controlled trial was to evaluate the effectiveness of a Driving Training Program, an intervention designed for student drivers with autism spectrum disorder (ASD). Participants were 72 student drivers with ASD (ages 16-31) who were randomly assigned to an intervention or control group. Student drivers…

Autistic adolescents experience a secondary wave of social cognitive challenges which impact interpersonal success. We investigated self-conscious emotion (SCE) processing in autistic and neurotypical adolescents. Participants watched videos of peers acting embarrassed and proud and rated inferred and empathic SCEs. We compared intensity ratings…
