Validity of Arabic Version of Beliefs About Medication Questionnaire.

To assess the validity and reliability of the Arabic version of the Beliefs About Medication Questionnaire, a cross-sectional design was used and the data were collected from 605 patients with chronic diseases. The study was conducted between July 2013 and December 2013. The results showed that the Cronbach's alpha coefficient (.71) was satisfactory. There was a significant strong positive correlation between test-retest for the same group subsample, with a correlation coefficient range of .45 to .78. There were no statistically significant differences between retest subgroups and remaining samples in the questionnaire subscales. The percentage of missing value was around 0.03, which confirmed the feasibility of the Arabic version of the questionnaire. These findings suggested that having a culturally acceptable, valid and reliable instrument to identify patients' beliefs toward medication in Jordan will play an important role in tailoring appropriate intervention to enhance patient compliance with their prescribed medication.
