The aim of this research was to explore the perspective, language, description, and practices of practitioners who identify as using mindfulness techniques for a range of health and clinical conditions. This study was guided by a qualitative descriptive methodology. Mindfulness practitioners from a variety of backgrounds that included medical, allied health, complementary and alternative medicine, and traditional Buddhism from across Australia were invited to share their perspectives. Semi-structured interviews were conducted via Zoom, telephone, and face-to-face which were audio-recorded and transcribed verbatim. The transcripts were thematically analysed. Sixteen mindfulness practitioners from Australia self-nominated to participate in this study. Overall, the interviews revealed similarities, differences and even disagreements between participants from the different modalities regarding mindfulness. Participants from similar disciplines also reported differing perspectives and nuanced opinions. Differences appeared to stem from both participant background, training, and the overall aims of their practice. This research highlights the complexities of what constitutes mindfulness. This study has highlighted, across a broad cohort, that for mindfulness practitioners, their beliefs, aims, and practices are varied and influenced by a range of factors including their ideological perspectives. While the diversity and broad application of mindfulness may be one of its strengths, it may also be its weakness as its value may be diluted due to plurality of understanding and multiplicity in use. This requires careful and considered actions from mindfulness stakeholders.
