Exploring dental hygiene decision making: A quantitative study of potential organizational explanations

To improve public access to oral health care, dental hygienists have been identified for practice expansion, and, therefore, they must demonstrate decision-making capacity. This study aimed to identify and test potentially influential factors in dental hygiene decision making. Organizational and gender factors were hypothesized to be most influential and focused the study.

A 2-phase mixed methods approach was used. In Phase I, a qualitative decision-making model was developed and subsequently published in 2012. Phase II tested aspects of the model through an electronic survey instrument and key informant interviews. This article reports on the statistical results of the quantitative survey. A third article will report on the qualitative thematic analyses and merged interpretation.

The Phase I qualitative model guided the development of the survey instrument. The survey had a 38% response rate; moderate to weak correlations between predictor variables (structural and individual) and clinical decision making were shown. The final statistical model demonstrated that individual characteristics and graduating from a 3-year dental hygiene program were together significantly associated with decision-making capacity.

Individual characteristics and longer education were together shown to be associated with increased decision-making capacity. These findings did not show the organization or gender to be important in influencing decision-making capacity. However, the merging of the quantitative survey and qualitative key informant data will potentially inform how the organization influences the individual dental hygienist.
