Abstract

Background: Medicine-related burden is an increasingly recognised concept, stemming from the rising tide of polypharmacy, which may impact on patient behaviours, including non-adherence. No instruments currently exist which specifically measure medicine-related burden. The Living with Medicines Questionnaire was developed for this purpose.

Methods: Questionnaires were distributed in community pharmacies and public places in south-east England, or online via UK health websites and social media. A total of 1177 were returned 507 (43.1%) from pharmacy distribution and 670 (56.9%) on-line. Construct validity was assessed by principal components analysis and item reduction undertaken on the original 60-item pool. Known-groups analysis assessed differences in mean total scores between participants using different numbers of medicines and those requiring assistance with medicine use. Internal consistency was assessed by Cronbach’s alpha. Free-text comments were analysed thematically to substantiate underlying dimensions.

Conclusions: The resultant Living with Medicines Questionnaire (LMQ-2) is a valid and reliable multidimensional measure of prescription medicine use experiences, which covers more diverse domains than existing questionnaires. However, further validation work is necessary.
