Health-related quality of life of children with developmental disabilities in Singapore and associated factors: A broad-based examination

The study investigates the health-related quality of life (HRQoL) of elementary-aged children with developmental disabilities in Singapore, focusing on the influences of individual and family factors. Data from 113 students from special education schools was examined, with data collected from parents, teachers, and direct assessments of the children. The Pediatric Quality of Life Inventory (PedsQL) was used to measure HRQoL across four domains: physical, emotional, social, and school functioning. Results showed that children with developmental disabilities generally experience lower HRQoL compared to typically developing peers, with the social functioning domain presenting the greatest challenges. Executive functioning difficulties emerged as the most significant predictor of overall HRQoL, affecting all domains, particularly social and school functioning. Parental psychological well-being was also significantly associated with children's emotional functioning, highlighting the broader influence of family factors on children’s well-being. This study contributes to the literature by examining a broad-based sample in a multicultural Asian context. Results underscores the importance of addressing both child-specific challenges, such as executive functioning, and family-centered interventions to improve parental mental wellbeing. In the pursuit of positive quality of life for children with developmental disabilities across multiple domains, this study’s findings highlight the need for a multi-component approach. Limitations and future directions, including the use of proxy reports and the need for culturally relevant interventions, are discussed.
