Background: Disability is a worldwide phenomenon that can result from a wide range of diseases and injuries affecting a considerable proportion of the population. The experience that people with disabilities have with health care is a complex interaction between their medical condition and the social and physical environment. Attitudes of the healthcare staff affect the quality of care and people’s adaptation to their disability, self-image and rehabilitation outcomes. Objectives. To examine and compare undergraduate healthcare students’ attitudes toward people with physical or intellectual disabilities and their sociodemographic correlates in Greece. Methods: In this cross-sectional survey, 1007 Nursing, Social Work, and Medicine students (79.4% female) attending three Universities in Athens and Crete completed during 2014-2016 two standardized scales regarding physical (ATDP – B, Attitudes Toward Disabled People – Form B) and intellectual disability (CLAS – ID, Community Living Attitudes Scale – Intellectual Disability). Descriptive and multivariate logistic regression analyses were performed. Results: Attitudes toward physically disabled people in Greece (ATDP – B scores) were poor with scores just above the mid-point. Medical studies and higher knowledge and contact with individuals with physical disabilities signified marginally more positive attitudes. Gender and age displayed no associations with ATDP – B attitudes scores. Regarding intellectual disability (CLAS–ID scores), nursing students had slightly less positive attitudes in ‘Similarity’ but more positive attitudes in ‘Sheltering’ subscales. Previous work and contact was related to more favourable and higher age to less favourable ‘Similarity’ and ‘Sheltering’ attitudes. Males had higher ‘Exclusion’ scores. Those who knew people with intellectual disabilities had less favorable ‘Empowerment’ attitudes. Knowledge was related to more positive attitudes in all four CLAS – ID subscales. Conclusions: Greek health and social care students showed poor attitudes towards people with physical and intellectual disability. Undergraduate and continuing education, along with workplace enhancements, should aim to provide high quality health care to people with disabilities.
