Enhancing Handwriting Performance in Autistic Children: A Randomized Crossover Study on the Effectiveness of a Spatial-Structured Handwriting Intervention Program / Jia LE PONG in Autism Research, 18-10 (October 2025)

Research indicates that autistic children often demonstrate poor handwriting fundamentals, which significantly affect their handwriting performance. These children also often exhibit weak central coherence (WCC), a cognitive visual processing characteristic that impairs their ability to integrate details into a cohesive whole in writing tasks. This challenge is particularly pronounced in logographic handwriting, where spatial relationships between radicals are essential for legibility, adding another layer of complexity. The modified geometric-based handwriting intervention program was designed to improve fundamental skills while addressing the spatial demands of logographic characters and the impact of WCC for autistic children. Twenty-two first- and second-grade autistic students were recruited and received a 12-h one-on-one handwriting intervention. Assessments of handwriting performance (legibility and speed), fundamental skills (visual perception, fine motor coordination, and visual-motor integration), and acceptability (motivation and satisfaction) were collected for data analysis. Results showed significant improvements in handwriting legibility, visual perception, and fine motor coordination, with high acceptance ratings from both participants and caregivers. This study provides evidence that the program effectively enhances handwriting legibility and foundational skills while maintaining high motivation levels in autistic children.

Feasibility and Preliminary Efficacy of a Caregiver-Assisted Group-Based Naturalistic Developmental Behavioral Intervention Program for Autistic Preschoolers: A Pilot Randomized Controlled Trial / Guan-Jye SENG in Autism, 30-9 (September 2026)  

Public ISBD [article]  inAutism > 30-9 (September 2026) . - p.2208-2224 Titre : Feasibility and Preliminary Efficacy of a Caregiver-Assisted Group-Based Naturalistic Developmental Behavioral Intervention Program for Autistic Preschoolers: A Pilot Randomized Controlled Trial Type de document : texte imprimé Auteurs : Guan-Jye SENG, Auteur ; Ji-Yu LIN, Auteur ; Wei-Lieh HUANG, Auteur ; Hsin-Yu LAI, Auteur ; Wei-Chih KAO, Auteur ; Hao-Ling CHEN, Auteur ; Susan Shur-Fen GAU, Auteur Article en page(s) : p.2208-2224 Langues : Anglais (eng) Mots-clés : autism  naturalistic developmental behavioral intervention  group-based delivery  preliminary efficacy Index. décimale : PER Périodiques Résumé : Naturalistic Developmental Behavioral Interventions (NDBIs) effectively improve developmental, social, and adaptive outcomes in autistic children, with caregiver involvement further enhancing treatment effects. Although one-on-one NDBI programs are strongly supported by evidence, their reliance on high staff-to-child ratios and certified therapists limits scalability. Group-based NDBI models may represent a more feasible and cost-effective alternative, particularly when implemented with open-access fidelity frameworks and active caregiver participation. This pilot randomized controlled trial compared a caregiver-assisted, group-based NDBI program with a therapist-delivered one-on-one NDBI program in autistic children aged 2 to 5 years. Both interventions were administered twice weekly for 12 weeks, with fidelity monitored using the NDBI Fidelity (NDBI-Fi). Forty autistic children were enrolled, and 38 children were included in the final analyses. Both groups showed significant improvements over time in verbal development, social interaction, adaptive functioning, autistic symptoms, problem behaviors, and caregiver stress. A significant time-by-group interaction was observed for nonverbal development, with significant gains in the one-on-one NDBI group but not in the group-based condition. These preliminary findings suggest that a structured, caregiver-assisted group-based NDBI model that integrates caregivers’ assistance, maintains intervention fidelity, and reduces staffing demands is feasible and associated with changes over time, indicating its potential as a scalable intervention approach.Clinical trial registry: https://clinicaltrials.gov/study/NCT06221943Lay Abstract Early intervention can help young autistic children improve communication, learning, social skills, and daily functioning. One widely used approach, Naturalistic Developmental Behavioral Intervention (NDBI), teaches skills through play and everyday activities, while actively involving caregivers. However, traditional NDBI is typically delivered one-on-one by trained therapists, which can be costly and difficult for many families to access. This study evaluated a new, group-based NDBI program in which small groups of young children and their caregivers learned together with therapist guidance. Thirty-eight autistic children aged 2 to 5 years received two sessions per week over 12 weeks, with 19 receiving the group program and 19 receiving the therapist-delivered one-on-one intervention. Children in both groups showed meaningful improvements in language, social interaction, adaptive functioning, autistic symptoms, and behaviors. Caregivers in both groups also reported feeling less stressed. The group-based model was feasible and acceptable while supporting positive developmental changes. However, significant improvements in nonverbal development were observed only in the one-on-one intervention group. Overall, these findings suggest that caregiver-assisted group-based NDBI is a promising and more accessible early intervention option, especially in settings where individualized therapy is limited or difficult to obtain.

Functional but Inefficient Kinesthetic Motor Imagery in Adolescents with Autism Spectrum Disorder / Yen-Tsz CHEN in Journal of Autism and Developmental Disorders, 48-3 (March 2018)

Here we investigated the characteristics of action representation in adolescents with ASD through motor imagery (MI) using a hand rotation and an object rotation task. Comparable with the typically-developing group, the individuals with ASD were able to spontaneously use kinesthetic MI to perform the hand rotation task, as manifested by the significant biomechanical effects. However, the ASD group performed significantly slower only in the hand rotation task, but not in the object rotation task. The findings suggest that the adolescents with ASD showed inefficient but functional kinesthetic MI, implicating that their action representation might be preserved.
