The only significant predictor was age. Older
CLBP patients had less preference for a patient-centered,
participatory communication style and preferred open and
clear communication. However, for them, communication
about personal circumstances was more important than for
younger patients. This age effect, as the rather low explanation
of variance shows, was not very large. Table 5 shows
the effect by presenting the KOPRA scale values for three
different age groups.
