Dutch dental patients on informed consent: knowledge, attitudes, self-efficacy and behaviour.

Abstract

In The Netherlands, the legal doctrine of informed consent is established in the 'Medical Treatment Contract Act', which was introduced in 1995. This study assessed dental patients' knowledge, attitudes and self-efficacy, as well as their self-reported behaviour concerning informed consent. One hundred and twenty-eight patients (response rate: 91.4%) filled out a questionnaire on these topics, right after their treatment or consultation. Results show that only a minority of the patients is acquainted with the 'Medical Treatment Contract Act'. However, their specific rights concerning informed consent are better known. On the other hand, patients' attitudes and self-efficacy were less positive. Dental patients' self-reported behaviour, did not reflect their attitudes and self-efficacy though. Contrary to social-psychological theory, almost no significant relations were found between the four measured variables, and self-reported behaviour could hardly be predicted by patients' knowledge, attitudes and self-efficacy. In light of these findings, it is concluded that other factors, which take into account more of a consumerist perspective on the dentist-patient relationship, probably play a more important role in predicting to what extent patients assert their rights in dental practice.
