Inclusion of children with disabilities in mainstream child development research

This study investigated whether children with disabilities are excluded from mainstream child development research. Fifteen per cent of 533 articles from Child Development and Developmental Psychology (1996–2010) were randomly selected. The exclusion rate was 89.9% when no mention of participants with disabilities was interpreted as exclusion and 66.7% when only studies mentioning disabilities were surveyed; 74% of studies did not provide justification for exclusion. Most studies could have included children with disabilities. Inclusion could be increased by adopting universal design principles and accommodations so that more children with disabilities can gain equal access to research opportunities and the benefits that accrue.
