Sensory Design Towards the Built Environment for Autism: An Assessment of the Physical Environment of the Selected Shopping Centers in Davao City Through Autism ASPECTSS Design Index

Abstract

The rising number of individuals with autism spectrum disorder (ASD) highlights the need for more inclusive environments, yet ASD-friendly design remains underrepresented in architectural research. This study evaluates how well-selected shopping centers in Davao City accommodate individuals with ASD using the Autism ASPECTS Design Index. Through descriptive statistics and comparative analysis, the research compares three major malls—Abreeza Mall, Gaisano Mall of Davao, and SM City Ecoland. Abreeza Mall consistently scores the highest, while Gaisano and SM show varying performances. Statistical tests, including Kruskal-Wallis and ANOVA, confirm significant differences in overall performance and ASPECTSS scores. The Kruskal-Wallis Test indicates a statistically significant difference among the malls (H = 11.890, df = 2, p = 0.003). Likewise, ANOVA results show a significant effect of the shopping center on the ASPECTSS Design Index Score (F (2, 177) = 12.660, p < .001, η² = 0.125). Further analysis of Dunn's and Tukey's post hoc tests highlights differences between the malls. These findings emphasize the importance of creating sensory-friendly shopping environments for individuals with ASD.
