The adaptation and feasibility of dialectical behaviour therapy for adults with intellectual developmental disabilities and transdiagnoses: A pilot community-based randomized controlled trial.

INTRODUCTION: Preliminary evidence suggests dialectical behaviour therapy (DBT) may be beneficial for persons with intellectual disabilities. This pilot randomized controlled trial aimed to determine the feasibility of adapted DBT for adults with intellectual disabilities and co-morbid psychiatric disorders in the community. METHODS: An adapted DBT programme (aDBT-ID) was delivered to adults with mild-to-moderate intellectual disability (n = 20) and their caregivers (n = 20). A single-blind, mixed-methods design was employed with treatment (n = 10) and control (n = 10). In addition to feasibility, pre-post-measures of emotional regulation, anger and mental health were taken from clients and caregivers. RESULTS: Results suggest it was feasible and beneficial to deliver adapted DBT in the community. Qualitative findings found both participants and caregivers were satisfied with the treatment delivery. No differences between conditions were found. CONCLUSION: This pilot study highlights the feasibility of adapted DBT for individuals with intellectual disabilities and the practicalities of delivering community-based inclusive research.

Social orienting predicts implicit false belief understanding in preschoolers.

According to the social motivation theory, orienting toward social elements of the environment should be related to sociocognitive abilities, such as theory of mind (ToM), in both typically developing children and children with autism spectrum disorder. The objective of the current study was to assess whether social orienting skills predict ToM abilities in preschoolers by using two social orienting tasks (biological motion and face preference) and an implicit false belief task. A total of 38 children, aged 2-4 years, participated in this study. As expected, participants showed a social preference on both tasks measuring social orienting. More importantly, children's performance on the face preference task predicted their performance on the false belief task, providing the first evidence for a link between social motivation and ToM in preschoolers.

Social motivation and implicit theory of mind in children with autism spectrum disorder.

According to the social motivation theory of autism, children who develop Autism Spectrum Disorder (ASD) have early deficits in social motivation, which is expressed by decreased attention to social information. These deficits are said to lead to impaired socio-cognitive development, such as theory of mind (ToM). There is little research focused on the relation between social motivation and ToM in this population. The goal of the present study was to investigate the link between one aspect of social motivation, social orienting, and ToM in preschoolers with ASD. It was expected that, in contrast to typically developing (TD) children, children with ASD would show impaired performance on tasks measuring social orienting and ToM. It was also expected that children's performance on the social orienting tasks would be correlated with their performance on the ToM task. A total of 17 children with ASD and 16 TD children participated in this study. Participants completed two social orienting tasks, a face preference task and a biological motion preference task, as well an implicit false belief task. Results reveal that TD children, but not children with ASD, exhibited social preference as measured by a preference for faces and biological motion. Furthermore, children with ASD tended to perform worse on the ToM task compared to their TD counterparts. Performance on the social motivation tasks and the ToM task tended to be related but only for the TD children. These findings suggest that ToM is multifaceted and that motivational deficits might have downstream effects even on implicit ToM.

LAY SUMMARY: The goal of the present study was to examine the link between poor attention to social information and mindreading abilities in children with autism spectrum disorder (ASD). Results demonstrated that children with ASD tended to perform worse than neurotypical children on both social orienting and theory of mind tasks. Preference for human faces and motion tended to be related but only for the neurotypical children. These findings provide partial support for the social motivation theory.

Biological motion primes the animate/inanimate distinction in infancy.

Given that biological motion is both detected and preferred early in life, we tested the hypothesis that biological motion might be instrumental to infants' differentiation of animate and inanimate categories. Infants were primed with either point-light displays of realistic biological motion, random motion, or schematic biological motion of an unfamiliar shape. After being habituated to these displays, 12-month-old infants categorized animals and vehicles as well as furniture and vehicles with the sequential touching task. The findings indicated that infants primed with point-light displays of realistic biological motion showed better categorization of animates than those exposed to random or schematic biological motion. These results suggest that human biological motion might be one of the motion cues that provide the building blocks for infants' concept of animacy.

The animate-inanimate distinction in preschool children.

This study examined the development of the animate-inanimate (A-I) distinction in relation to other taxonomic categories in early childhood. Four- and 5-year-old children were administered two tasks measuring knowledge of taxonomic categories at various levels of inclusiveness. Across both matching-to-sample and object sorting tasks, the same pattern of categorization development was observed. Mastery of basic- and superordinate-level categories was demonstrated by 4 years of age. Although 5-year-old children performed above chance on A-I level categories, their abilities were not as mature as those of adults. Results of this study support and extend previous studies investigating the development of children's understanding of naïve biology during the preschool years.

Schematic and realistic biological motion identification in children with high-functioning autism spectrum disorder.

Research investigating biological motion perception in children with ASD has revealed conflicting findings concerning whether impairments in biological motion perception exist. The current study investigated how children with high-functioning ASD (HF-ASD) performed on two tasks of biological motion identification: a novel schematic motion identification task and a point-light biological motion identification task. Twenty-two HFASD children were matched with 21 TD children on gender, non-verbal mental, and chronological, age (M years = 6.72). On both tasks, HF-ASD children performed with similar accuracy as TD children. Across groups, children performed better on animate than on inanimate trials of both tasks. These findings suggest that HF-ASD children's identification of both realistic and schematic biological motion identification is unimpaired.
