Cross-sectional comparison of dental students' knowledge and attitudes before geriatric training: 1984-1999

The existence of negative attitudes toward aging and a lack of factual information has been voiced in the dental and other health professions. With increasing numbers of elderly in society, intergenerational social contact is more likely to occur and has the potential to reduce negative attitudes and increase knowledge about aging. The purposes of this study were to determine if the level of intergenerational social contact of dental students in one dental school had changed over the last fifteen years and whether any such changes were related to shifts in students' baseline knowledge about aging and attitudes toward elderly patients. Dental students (n=269) representing three different cohorts were surveyed about intergenerational contact, knowledge about aging, and attitudes toward elderly patients prior to receiving any geriatric training. Overall, findings revealed little evidence of increasing intergenerational social contact, an actual decrease in knowledge, an increased negative bias in knowledge, and unchanged attitudes toward elderly patients over the past fifteen years. Recent students were more likely to have had grandparents living in the family home, to have slightly less correct factual knowledge, and to be more negatively biased in their incorrect factual knowledge than earlier students. There were no differences in attitudes toward elderly patients among cohorts. We concluded that additional research is needed to confirm or refute our trends on a national scope. Should these trends be confirmed, dental educators would be alerted to the continuing necessity of countering the students' potential negative biases as well as a lack of basic knowledge about aging.
