Mindfulness as a clinical strategy for helping manage physical and psychological symptoms is gathering an impressive evidence base. It is also being embraced widely for personal and professional development. As a therapeutic intervention for nurses working across a spectrum of settings, it helps expand practice, and integrating mindfulness in nursing undergraduate and graduate curricula is imminent. In the present study, we outline the development and measurement of mindfulness as a personality trait and therapeutic intervention, and advocate the use of a questionnaire alternative to expensive and impractical laboratory measures. The aims of the present study were to examine and compare the use and reliability of the Five Facet Mindfulness Questionnaire (FFMQ) in samples of nursing students from South Africa, China, and the Philippines, and compare the findings in the nursing student samples to other student and non-student samples. Three samples of students of nursing from China (n = 193), the Philippines (n = 243), and South Africa (n = 131) completed the 31-item FFMQ. The internal consistency was acceptable, and the correlations were significant among all facets and the total score. Although the total mean scores between the three samples were not significantly different, there were significant and interesting differences in the facet scores, and these are discussed in the light of likely cultural influences, and comparative data from other samples of students and clinical populations. The instrument shows promise for future use in educational research as a tool for curriculum change, for personal and professional development of nurses, and as a clinical tool for determining mindfulness changes over time.
