Suitability of Krathwohl's affective taxonomy for evaluating patient attitudes to dental care.

The aims were to develop a questionnaire for dental health education based on Krathwohl's taxonomy, which measures the affective domain, and to examine correlations between the attitude determined by this questionnaire and sex, age, education, and dental behavior. The material consisted of young and middle-aged persons, 206 women and 183 men, visiting two occupational health centers in Oulu. The questionnaire comprised four questions under each of three headings: preventive dentistry, gingivitis, and dental check-up. The questions under each heading were formulated to correspond to given levels in Krathwohl's taxonomy. Factor analysis showed the questionnaire to be valid and suitable for studying different levels of the affective domain. Krathwohl's taxonomy includes the notion of cumulative adoption of a value, and Guttman scaling was used to show the cumulativeness of the scales. Groups of persons with the most and least positive attitudes were identified, 83% of the patients with the most positive attitude having visited a dentist within a year, whereas 65% of those with the least positive attitude had last done so more than 2 yr earlier. The women had a more positive attitude than the men, but education was not a decisive factor in determining attitude. All the persons with the most positive attitude were over 25 yr old. It was concluded that it was possible to formulate a questionnaire on the basis of Krathwohl's taxonomy which would measure attitudes towards dental care and that it is possible to use this questionnaire in practical situations in order to help the dentist to instruct his patients.
