<p>This quadrant model of medical research traditions
conceptualises research on a continuum of two axes. The x-axis is informed by
Engel’s biopsychosocial model<sup>1</sup> while the y-axis represents
the continuum between in-vitro and in-vivo research and methodologies. Laboratory-based
research is represented in the in-vitro/biomedical quadrant; clinical research
in the in-vivo/biomedical quadrant; simulation-based research in the
in-vitro/psychosocial quadrant; and professional practice research in the
in-vivo/psychosocial quadrant. Those traditions tending towards the biomedical
model might be best researched using quantitative positivist methodologies,
whilst those tending towards the psychosocial model might be best researched
using qualitative methodologies.</p>
<p> </p>
<p>Overlying the quadrants is the Taijitu (太极图/太極圖) better known in Western
traditions as a representation of Yin-Yang (阴阳/陰陽).
Its purpose is to act as a reminder that each medical research tradition is “complementary,
interconnected, and interdependent”<sup>2</sup>; and that there may be other
ways of finding and seeing truth and knowledge.</p>
