Background: It has been suggested that inequalities in health care for people with intellectual disabilities may be partly explained by negative attitudes of health professionals. This study aimed to investigate the attitudes and emotional reactions reported by nursing staff working in general hospitals towards caring for patients with intellectual disabilities. Method: Attitudes and emotional reactions were measured using a self-report, vignette style questionnaire, tested for validity and reliability. Attitudes towards patients with physical disabilities were also assessed to act as a comparison. Results: Nursing staff reported less positive attitudes, more negative emotions and fewer positive emotions, in response to caring for a patient with an intellectual disability compared to a patient with a physical disability. Occupational status (registered general nurse, student nurse, nursing assistant) had no effect upon respondents reported attitudes or emotions. Finally, attitudinal and emotional variables were significantly correlated, with positive emotions being associated with more favourable attitudes. Conclusions: Although caution needs to be exercised when inferring actual behaviour from attitudes expressed, it is suggested that the presence of less positive attitudes and feelings amongst nursing staff towards patients with intellectual disabilities may affect the quality of care. Recommendations for future research and service development includes: the need to focus upon improving attitudes of nursing staff through training, and increased joint working between acute care services and Community Intellectual Disability Teams.
