Assessing interdisciplinary education in U.S. dental hygiene programs.

This study was done to examine the role of interdisciplinary education in dental hygiene curricula, identify factors associated with its implementation, explore the perceptions of dental hygiene educators related to interdisciplinary education, and explore these educators' perception of its validity and barriers to implementation. A 36-item questionnaire mailed to directors of all 216 dental hygiene programs in the United States elicited program demographics and information about participation in clinical and didactic interdisciplinary educational experience as well as attitudes regarding such experiences. The response rate was 63% (n = 136). Of the 136 respondents, 31% (n = 69) indicated that the dental hygiene curricula at their institutions included interdisciplinary activities; 15% (n = 33) indicated participation in both clinical and didactic interdisciplinary course work. Student participation was minimal, with most interdisciplinary activities taking place in didactic course work, but 74% (n = 160) of the respondents felt their students should be participating in interdisciplinary educational experiences. Chi-square analysis identified no consistent association among interdisciplinary activity variables. Many respondents felt that interdisciplinary educational experiences would benefit their students, but very few had incorporated them into their curricula, citing lack of resources and time as reasons. In addition, the term interdisciplinary was interpreted variably.
