The purpose of this study is to examine Thai Dempster Practice Behaviors Scale [DPBS]. A blind back translation method is employed by the researchers and experts. Psychometric analysis was used that included reliability and exploratory factor analysis. A random sampling method was used to recruit 311 nurse practitioners in Eastern region. Data collection was by demographic record form and a self-administered DPBS questionnaire. Data was analyzed by percentage, Cronbach’s alpha coefficient, and factor analysis.
The results of the study revealed that the Cronbach’s alpha coefficient of the Thai version of the DPBS of nurse practitioners was .89 and factor analysis showed 7 factors of structure was an appropriate structure. The Cronbach’s alpha coefficient of each factor was .81, .76, .70, .68, .65, .73, and .60 respectively. The findings suggest that nurses and healthcare personnel can use this scale to evaluate the practice behaviors of nurse practitioners as a means for finding ways to scope the role of nurse practitioners
