Self-disgust is a complex emotion related to feeling aversion or revulsion about internal and personal physical attributes, personality, functioning and behaviours. The aim of the present study was to adapt, validate and examine the psychometric properties of the Multidimensional Self-Disgust Scale, in a sample of Portuguese adolescents (MSDS-A).…

During four decades, numerous school-based bullying prevention programmes have been developed and evaluated. Meta-analyses indicate that such programmes have positive average effects, as compared with treatment as usual. However, the effects are small to moderate, and they are especially weak among some specific groups, such as adolescents. After…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

This paper based on an online survey and follow up interviews, is part of a larger study exploring English parents reasons to home educate (H.E.) their children and their pedagogic practices. The 54 survey responses, from a total of 223, showed that 92 children aged 2-18 had never attended mainstream education. Respondents views on the purpose of…

Pre- and post-term children show increased autism risk. Little is known about gestational age (GA) prevalence among autistic children, and their respective autism phenotype. We compared prevalence of pre-, full- and post-term birth between a population-derived sample of N = 606 (137 females, 22.61%) autistic children and adolescents (mean age =…

Schools start early in the morning all over the world, contrasting with adolescents' late chronotype. Interestingly, lower academic performance (i.e. grades or qualifications) was associated with later chronotypes. However, it is unclear whether it is a direct effect of chronotype or because students attend school too early to perform at their…

In this study we examined how specific personality traits are related to psychosocial adjustment in people with intellectual disability. We studied 73 students with mild intellectual disability and 25 students with moderate intellectual disability who attended special schools in Poland. Personality traits were assessed with the Revised Edward…

Purpose: The current study addresses a gap in the literature regarding syntactic development of adolescent boys with fragile X syndrome (FXS) and Down syndrome (DS). Specifically, we ask whether syntactic skills plateau or continue to change during adolescence for these groups and whether the profile of syntactic change differs between boys with…

Youth with autism spectrum disorder (ASD) face challenges accessing needed services as they transition to adulthood. Correlates of service access identified in the literature--such as family resources, race/ethnicity, or youth functioning--can be difficult to change and may not be feasible targets for intervention. This study focused on a…

Engaging parents in school health examinations can promote adolescents' well-being. We examined parents' participation in universal school health examinations in Finland reported by adolescents in school surveys (14 to 16-year-olds, N = 58,232). Further we studied variation between service providers and schools, and student and school-level…

Children's early experiences have potential to shape their development through early childhood, middle childhood, and into adolescence. Family structure at birth and material hardship may offer insight into how children's health and well-being are shaped within their family of origin. The current paper examined (a) the association between family…

Autism is a lifelong condition characterized by repetitive and restrictive behaviors and differences in social communication. The reported prevalence of autism has risen exponentially in the past years. Early identification and subsequent early intervention are key to promoting better outcomes for autistic individuals. However, there is a dearth…

Background: Balanced and adequate nutrition is important to improve the quality of life of children with intellectual disability but most of these children are negatively affected by nutritional problems. Objective: This study was conducted to determine the nutritional status and effect of the severity of intellectual disability on nutritional…

Prior research on bullying victimization has often explored the behavior from a binary perspective in which victims and non-victims are examined. However, there has been an increasing amount of literature taking a more nuanced approach towards different subtypes of victims in recent years. This study sought to examine heterogeneous patterns of…

Many of the nearly six million autistic adolescents and adults in the United States require support to navigate daily life. Family members often provide the first line of support for autistic youth by providing care and coordinating services. Although considerable research has examined the perspectives of family members caring for young autistic…
