Effect of Interior Architecture of Rehabilitation Centers on the Outcome of Occupational Therapy for Children With Autism Spectrum Disorders. (English)

Objective Autism spectrum disorder (ASD) is a common disorder among children. The architectural design of the treatment environment can be effective in the quality of rehabilitation for these children. On the other hand, considering that an important part of treatment for children with ASD is to meet their sensory needs, there is a need for intervention and adaptation to the environment (sensory regime). The study aims to investigate the effect of the interior architecture of rehabilitation centers on the outcome of occupational therapy for children with ASD. Materials & Methods This is an observational cross-sectional study on 50 children with ASD aged 3-14 years, who were assigned into two groups of treatment in standard and non-standard environments, according to interior architectural factors. They were assessed before and after occupational therapy. To rank the physical space of rehabilitation centers, a researcher-made questionnaire was used with 30 criteria measuring natural light intensity, light quality (natural or artificial), visibility and view of the inside of the building, noise and visual pollution, and color of the walls. The criteria were based on the opinions of 32 occupational therapists and parents of 50 ASD children. The sensory profile 2 was used to measure sensory processing patterns (sensation seeking, sensation avoiding, sensory sensitivity, and sensory registration) of children with ASD. The paired t-test was used for within-group comparison, and the independent t-test was used for between-group comparison. Results Both standard and non-standard treatment environments were effective in improving all four patterns of sensory processing (P=0.04). However, the rehabilitation center with standard design had a more significant positive effect on all four sensory processing patterns, including sensation seeking (P=0.001), sensation avoiding (P=0.001), sensory sensitivity (P=0.01), and sensory registration (P=0.001) compared to the non-standard environment. Conclusion The interior architecture of rehabilitation centers has a significant positive effect on the sensory processing patterns of children with ASD, which can affect the quality of rehabilitation services. Therefore, it is recommended to optimize the interior architecture of rehabilitation centers for ASD children. [ABSTRACT FROM AUTHOR]
