This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the…

Feeding challenges are a significant concern for autistic children. Literature has yet to comprehensively characterize feeding challenges for autistic children. Further research is needed to understand predictors of feeding severity and identify opportunities for screening and intervention. The purpose of this study was to characterize the…

Fear of darkness is prevalent in childhood, yet how children explain it remains unknown. The purpose of this study was to investigate how preschoolers make sense of fear of darkness. Semi-structured interviews were conducted through Zoom with 4- to 5-year-old Russian children (n = 31; 13 girls). Reflexive thematic analysis revealed that…

Familiarity is a crucial element in narrative fiction reading for children, playing a significant role in social learning from storybooks. Nevertheless, distinct studies greatly vary in their interpretation of what renders a storybook familiar to a child, researchers' methods for measuring familiarity, and how researchers link familiarity to…

Background: The impact of having a disabled brother or sister on siblings' psychological well-being and sibling relationships has been the subject of several research studies. However, research which focuses on the relationship between siblings and their autistic brother or sister with an intellectual disability and complex care needs is rare. We…

Sibling relationships may be strained when one sibling is diagnosed with autism and the other is not. The way that siblings interact during play is one indicator of the quality of this relationship. Non-autistic siblings have been taught to encourage play in their autistic siblings, but there is limited literature examining the impact of…

Parenting style plays an important role in children's externalizing behaviors. Differences in physiological regulation among children may lead to variations in whether or to what extent parenting style influences them. The present study aimed to investigate the effect of parenting styles on young children's development of externalizing behaviors…

According to coercion theory (Patterson, 1982, 2016), children's aggression is developed and maintained through transactional processes between parents and their children that unfold over time. The theory provides a model of the behavioral contingencies that explain how parents and children mutually "train" each other to behave in ways…

The emergence of moral emotions such as guilt is central in moral and prosocial development. Guilt is an important psychological factor, which motivates prosocial behaviour and is credited for multiple social functions. Importantly, it remains unclear what determines the extent to which children show guilt. The current study examined two factors…

Objective: People with intellectual disabilities have historically often been excluded from cognitive based therapies, due to their cognitive deficits. However, adults with intellectual disabilities have been found to have the core cognitive abilities necessary to engage in Cognitive Behaviour Therapy. Despite this emerging evidence, the capacity…

Adolescents' mental health and academic performance are subjects of paramount interest. Previous studies have revealed a strong association between these constructs during school years. However, there is little evidence about the dual-factor model of mental health, which includes a combination of psychological well-being and distress indicators,…

Identifying infants at elevated likelihood for autism and other developmental differences in the first year of life remains a significant challenge. This study explored associations between behavioral differences in infancy and developmental outcomes in toddlerhood. We conducted a secondary data analysis of 256 infants with an older autistic…

Digital natives, who encounter technology from the moment they are born, are individuals whose lives revolve around new technologies. Children must stay safe in online environments. Understanding the relationship between their digital competencies and cyberbullying can assist in developing effective strategies to enhance online safety. This study…

Emotion dysregulation is one of the challenges that children with autism spectrum disorder (ASD) and their families face. It is unclear whether emotion dysregulation plays a mediating role in the relationship between sensory processing patterns and problem behaviors among these children. This study examined the relations between emotion…

Purpose: The study objective was to determine if the validated Behavioral Inflexibility Scale (BIS) is sensitive to the detection of developmental changes in inflexibility in a sample of autistic children. Methods: Parents of autistic children (n = 146, 3-17 years) completed the BIS at two time points, one year apart, to examine change. Results:…
