Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

Studies on the impact of the COVID-19 pandemic on autistic children's psychosocial outcomes have shown mixed results. In the current study we aimed to gain a better insight into the effect of the COVID-19 pandemic by comparing psychosocial outcomes collected pre-pandemic with data collected during the pandemic. We used the Strengths and…

Some of the worst long-term outcomes of children are associated with the presence of both externalizing behavior and low academic achievement. Additionally, trajectories of externalizing problem behavior have shown that when children enter kindergarten with problem behavior, it tends to persist and is often associated with low academic…

Although out-of-school school suspensions have been correlated with negative school outcomes, they are still a common formal response given to students whose behavior is deemed problematic. Being suspended multiple times within an academic year results in students losing even more instructional time. In this study, we used longitudinal data for…

Recent research suggests there may be differences in the social presentations of autistic males and females. Camouflaging is believed to account for some of these differences and executive function (EF) may support compensatory social behaviors. As few studies have explored the role of sex and everyday EF when evaluating specific social…

This preregistered, longitudinal study examined how much adolescents value and integrate their parents' and peers' attitudes into their own attitudes from early to middle adolescence. Across three waves, participants (N = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers'…

The purpose of this study was to identify predictors of friendship quality in adolescents with and without ADHD. The participants were 115 adolescents (61 ADHD, 54 non-ADHD), ages 13-18. The adolescents completed questionnaires assessing the quality of their relationships with their best friends, social perspective taking, anxiety and depression.…

Background: It has become increasingly important to shift education research and programming from a deficit focused perspective to a positive youth development perspective in order to identify and promote factors that support students' positive functioning and outcomes. One outgrowth of positive youth development is Positive Mental Health (PMH),…

The beneficial relationship of school climate with various positive student outcomes has been demonstrated in several studies, though the relationship has not been thoroughly explored with regards to a student's likelihood of being suspended from school. The relationship of school climate and out-of-school suspensions was investigated using a…

While research suggests that social emotional competencies (SECs) influence students' disciplinary outcomes, less is known of their potential to explain racial disparities or grade level differences in those outcomes. This study used survey and administrative data from 30,494 students in grades 3-12 to examine the degree to which SECs were related…

The present study investigated the longitudinal associations of self-control and parental involvement with prosociality and internalizing problems from early to mid-to-late adolescence, within a risk and resilience and a developmental cascade framework. We used a panel design (i.e., four measurement times at 2-year intervals from 2008 onwards) to…

Past research suggests that children, particularly those with autism spectrum disorder, with general behavioral inflexibility to objects, persons, and environments may be at risk for feeding problems. However, questions remain about whether feeding problems are better predicted by behavioral inflexibility or sensory sensitivity, and whether…

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

Deception is a common phenomenon in everyday life, yet some people generally lie more than others and some people consider lying more acceptable than others do. Current knowledge about lie acceptability across development or about the individual differences in emotion or personality which shape it is still in an incipient stage. We aimed to expand…

Physical abuse is one subtype of child abuse and it has been a worldwide public health issue for its detrimental effects on child development, profiles, predictors, and its relation with behavior problems need further exploration, particularly in Chinese children. This study attempts to explore profiles and predictors of physical abuse and to…
