A non-anonymous questionnaire was distributed to all nursing staff (n = 557) including RNs, LPNs (psychiatric), LPNs (somatic) and nurses' aides, in one nursing home, one somatic long-term care clinic and one psychogeriatric clinic. Scales measuring empathy, burnout experience and attitudes towards demented patients were included in the questionnaire. The aim of the study was to compare levels of empathy, burnout experience and attitudes among different categories of nursing staff and to examine connections between empathy, burnout and attitudes. The nursing staff showed an overall figure of moderately well-developed empathy and the RNs showed the highest empathy. The RNs had a significantly lower degree of burnout compared to the nurses' aides and the LPNs. Of all respondents, 27.4% were assessed at risk from burnout. Overall, the staff showed a moderately positive attitude towards demented patients and the RNs were most positive. No linear correlation was found between empathy, burnout experience and attitudes. However, a weak negative correlation between burnout and empathy is in accordance with other authors who are suggesting that burnout experience leads to lower empathy in the nursing staff. The fact that the RNs showed the most positive attitudes towards demented patients and had the highest level of empathy compared to LPNs and nurses' aides could be related to lower degree of burnout assessed in the RNs. Qualitative and quantitative overload among the LPNs and nurses' aides connected to the growing number of demented patients in the institutions examined are discussed.
