| Summary: | 碩士 === 長庚大學 === 商管專業學院碩士學位學程在職專班醫務管理組 === 106 === Medication literacy is a specific type of literacy, as the ability of individuals to safely and appropriately access, understand and act on basic medication information. Medication literacy has been proposed since 2005, and it is considered to be more suitable for the development of appropriate medication information than health literacy to improve patients’ pharmaceutical care outcomes. In order to make the assessment of literacy measurement more comprehensive, and to make the measurement process closer to the real life situation of taking medications, we develop a new medication literacy measuring instrument Multiphasic Medication Literacy Scale (MMLS). On the basis of literature review, the MMLS is designed from health literacy construct and previously developed medication literacy measuring instrument. In addition to the basic functional literacy (document, numeracy, and prose), the scale also adds the common medicine information communicated with patients in pharmacy service including critical literacy measurement items, and the contents of the information printed on a medicine bag, medication teaching leaflets, and official meditation news . The aim of our study is to establish the reliability and validity of this MMLS. Using a cross-sectional design, 138 subjects were recruited by convenience sampling at the outpatient departments of two hospitals(Taipei Renji Hospital and Sinjhuang Renji Hospital). To reduce measurement burden, We use item response theory to shorten the scale. The final version MMLS is a 17-items scale that contains 8 document literacy items, 4 numeracy items, 3 prose literacy items, and 2 critical literacy items, which accounted for the 80.95% of the total information. MMLS showed good retest stability (r=0.867, p<0.01), internal consistency reliability (Cronbach's α=0.823), and criterion validity (different identities: F test=43.493, p<0.001; different education level, F test=33.525, p<0.001). In conclusion, the MMLS appeared to be a valid and reliable instrument for measuring medication literacy. It can provide related indicators to be used in analysis and intervention studies of medicine literacy as a basis for strategic considerations of pharmacy services.
