This research is conducted to see the amount of social distances between the persons with disabilities and the persons without disabilities and to find main factors affecting social distances. Total 1,023 samples selected throughout the whole country were surveyed through telephones in July, 2008. Major findings of this study could be summarized as follows; In terms of contact factors affecting the discriminatory attitudes are ‘existence and non-existence of the disabled in family’and‘existence and non-existence of the disabled in friends’in case of disabled persons, and ‘contact experience’,‘contact quality’,‘existence and non-existence of the disabled in family’,‘existence and non-existence of the disabled in relatives’and‘existence and non-existence of the disabled in neighborhood’, ‘existence and non-existence of the disabled in friend\',‘existence and non-existence of the disabled in fellow employees\' in case of normal person. Results drawn from the hierarchical multiple regression analysis to determine major factors affecting the discriminatory attitudes have shown that stereo type, negative emotion for the disabled, sex and income are statistically meaningful variables in case of persons with disabilities, and that stereo type, negative emotion for the disabled, contact experience and contact quality, age, income are statistically meaningful variables in case of persons without disabilities. In terms of social distances against persons with disabilities, these results between the persons with disabilities and the persons without disabilities suggests that we need to map out a separate strategy for eliminating the discriminatory attitudes for the persons with disabilities. From these findings, some practical implications for eliminating the discriminatory attitudes for the persons with disabilities are discussed. keywords: persons with disabilities, social distance, stereo type, negative emotion, contact experience, contact quality
