WebbOne specific issue in terms of reliability is the calculation of inter-rater reliabilities, which by definition requires more than one coding (i.e., "rating") of the data. WebbA number of medication self-efficacy measures are available; however, there is no systematic review of existing instruments and cataloguing of their theoretical underpinnings or psychometric properties, strengths, and weaknesses. The aim of the study was to identify instruments that measure self-efficacy for medication management.
