Background: The purpose of this study was to explore the role of everyday executive functions in relation to intelligence and adaptive behaviour in children and adolescents with mild intellectual disability. Method: A group of children and adolescents, previously diagnosed with mild intellectual disability were assessed according to intelligence,…

Adaptability (adjustment to new and uncertain situations) and grit (perseverance and passion for long-term goals) both sustain students, but their joint contribution has never been explored, and recent studies propose they could compose a single factor. In this study we aim to test whether (1) they actually belong to a single overarching factor as…

The use of self-report to assess anxiety in adolescents with intellectual disability (ID) is notably underexplored. This study examined the impact of youth-level factors (i.e., age, verbal and cognitive ability, adaptive skills) on anxiety self-report completion and parent-youth agreement among 72 autistic adolescents with ID. We also examined if…

Investigating the adoption and use of the host language is one common method for studying acculturation among immigrants. What is less known is how this type of acculturation changes over time and how individual patterns of change can affect other adaptation processes in the host country, for example within families. This study investigated…

The current study examined three research questions: (a) Are unmarried at birth fathers' prenatal and birth-related behavioral, attitudinal, and identity adjustments directly related to father engagement in child-related activities during early childhood and father-child closeness in middle childhood and adolescence? (b) Do father engagement in…

This study examined the relations between normative developmental changes of familism values and later internalizing and externalizing behaviors in Latinx adolescents from an emerging immigrant community. The sample included 547 Latinx adolescents (55.4% female; baseline M[subscript age] = 12.80; SD = 1.03) residing in the Southeastern United…

It is well established that successful transitions into adulthood vary greatly by numerous factors (e.g., race, gender); yet, understanding of ways that disability-related factors shape transitions into adulthood are less clear. While individuals with disabilities, generally, often fall short of their non-disabled peers in achieving many early…

Introduction: Challenging behaviors are common in individuals with developmental disabilities and pose significant challenges to their well-being and that of their families and communities. Method: We explored the occurrence and predictors of self-injurious behavior and aggressive/destructive behavior in 372 Canadian youths (aged 4-20 years) with…

Family and school factors are among the most important determinants of internalizing and externalizing problem behavior in adolescents. The aim of this study is to explore how certain family and school factors explain internalizing and externalizing problems after one year. In addition to individual-level variables, school level variables are…

High rates of attention deficit/hyperactivity disorder (ADHD) comorbidity have been described in autism spectrum disorder (ASD). This study searched for predictors at toddlerhood of the severity of ADHD symptoms at adolescence. The study included 65 participants, (mean age = 13:8 year), diagnosed with ASD at toddlerhood. Participants underwent a…

'High functioning autism' is a term often used for individuals with autism spectrum disorder without an intellectual disability. Over time, this term has become synonymous with expectations of greater functional skills and better long-term outcomes, despite contradictory clinical observations. This study investigated the relationship between…

The period of transition between education and employment can be difficult for young people, particularly young immigrants. Human capital theory argues that higher levels of educational attainment should lead to improved likelihood of employment. However, although young immigrants have higher, on average, levels of educational attainment than…

Adolescent risk-taking can potentially result in serious individual and societal consequences. Previous research demonstrates that emotional and behavioral problems, particularly externalizing behaviors, are significantly associated with an array of risky behaviors such as substance use, sexual behavior, injury, and violence. However, the…

This study characterizes longitudinal change in adaptive behavior in 64 children and adolescents with autism spectrum disorder (ASD) without intellectual disability evaluated on multiple occasions, and examines whether prior estimate of executive function (EF) problems predicts future adaptive behavior scores. Compared to standardized estimates…

Almost half of all children with autism spectrum disorder have average cognitive abilities, yet outcome remains poor. Because outcome in HFASD is more related to adaptive behavior skills than cognitive level it is important to identify predictors of adaptive behavior. This study examines cognitive and demographic factors related to adaptive…
