A Meta-Analysis of School-Age Children's Attitudes Towards Persons with Physical or Intellectual Disabilities

Factors associated with children's attitudes towards persons with physical and intellectual disabilities were examined in a meta-analysis spanning the years 1990 to 2000. A total of 20 studies met the inclusion criteria allowing for 65 comparisons across 2,240 participants. Factors of interest were attitudinal components, type of disability, age and gender of respondents, and role of inclusion. The majority of research findings revealed that children preferred target children without disabilities compared to targets with physical or intellectual disabilities. Three methods for calculating average effect sizes were used: (a) unweighted means, (b) weighted means, and (c) vote counting. It was concluded that biases in attitudes do exist but that summary results need to be interpreted with regard to individual study differences and the methods used to calculate mean effect sizes.
