Patients' views about taking antihypertensive drugs: questionnaire study

Abstract
With local research ethics committee approval, we developed a questionnaire deriving items and language from the earlier qualitative analysis. After two face to face pilots (five questionnaires) and two postal pilots (44 questionnaires), the questionnaire included questions about patients' reservations about drugs, their experience of unwelcome side effects, and their reasons for taking antihypertensives.
