Validation of a new tool for evaluating subjects' satisfaction with medicine package leaflets: a cross-sectional descriptive study

by Afonso M Cavaco and Pedro J Rosa

According to the European Guideline on the Readability of the Labelling and Package Leaflet of Me... more According to the European Guideline on the Readability of the Labelling and Package Leaflet of Medicinal Products for Human Use, package leaflets of medicines (from here on, referred to simply as package leaflets) need to be simple, clear and comprehensible. This is why legibility tests involving groups of patients need to be conducted, so as to ensure that package leaflets are readable. 1 Additionally, in designing package leaflets, special focus should be given to elements such as use of a simple writing style, adequate font size and layout (e.g. line spacing, use of bullet points and consistent headings) and adequate contrast. 2 Questionnaires using Likert scales (i.e. a psychometric scale for questionnaires comprising an intermediate value and an odd number of alternatives, usually five or seven) are commonly used in readability/legibility tests to evaluate the readability of package leaflets. In these tests, the scores of the Likert scales are often used to check readability after package leaflets have been optimized, i.e. test-retest methodology is usually applied. These scales are easy to apply and often present high response rates (84-91%) and completion rates (70-85%). 4,7 Another advantage is that 20-item questionnaires in which responses are assessed using a Likert scale can be completed fast: in less than five minutes if the questionnaire is simple. Lastly, these tools give rise to good internal consistency, reliability and construct validity. 7
