Attitudes towards people with dementia: a cross-sectional study comparing dental hygiene students with registered dental hygienists.

Abstract

In order to adequately care for patients with dementia, it is necessary for dental hygienists to develop unprejudiced attitudes towards and obtain sufficient knowledge of dementia. The aim of this study was to assess attitudes towards and knowledge of dementia among Japanese dental hygiene students and identify related factors to the attitude and the knowledge. We compared the attitude and the knowledge between dental hygiene students and practising dental hygienists. Dental hygienists are required to care for patients with dementia by developing appropriate attitudes towards dementia and gaining knowledge of dementia. Between May 2016 and July 2016, 191 third-grade dental hygiene students and 64 registered dental hygienists were surveyed. We modified questionnaires to assess attitudes towards and knowledge of dementia. Ageism was assessed using the Fraboni Ageism scale. To determine potential dementia awareness factors, information regarding participants' experiences with dementia was collected. Factor analysis revealed four factors in the attitude scale (Cronbach's α, 0.652-0.820). All item-total correlation coefficients for the knowledge scale were above 0.3, and Cronbach's α was 0.827. All awareness factors for dementia were significantly different between students and registered dental hygienists. Total scores of attitude and knowledge were higher among registered dental hygienists, indicating better attitude and knowledge, but total scores of ageism were lower among registered dental hygienists, indicating worse ageism. Multiple regression analysis revealed that the attitudes towards dementia correlated with years of experience, ageism, interest in dementia and desire to work with patients with dementia. Registered dental hygienists had more positive and more knowledge compared to dental hygiene students. Attitudes towards dementia, but not knowledge of dementia, were significantly positively correlated with ageism.
