Background
the choice of the appropriate tool for assessing level of medication adherence is a significant barrier in scientific research.
Aims
to translate into Greek and test the reliability of the Hill-Bone and A-14 scales among patients with hypertension. Also, to compare patients' responses in the Hill-Bone scale, A-14 scale and Morisky Medication Adherence Scale (MMAS).
Methods
data collection occurred between February 2016 and March 2016 at a general hospital in Athens, Greece. The sample consisted of hypertensive patients (n=34) and non-hypertensive patients (n=34).
Findings
the coefficient alpha in hypertensive patients was 0.76 for Hill-Bone, 0.64 for MMAS and 0.91 for the A-14 scale. In non-hypertensive patients, the Cronbach's alpha for MMAS was 0.81 and 0.78 for A-14. A statistically significant difference was found among the mean scores of the scales, whereas strong correlation was found only between two pairs of questions with similar meaning.
Conclusion
all tools are appropriate to assess the level of medication adherence in Greek hypertensive patients. However, careful translation of the scales is essential since items with the same meaning could be understudied in a different way.
