Factor Structure of Pain Medication Questionnaire in Community‐Dwelling Older Adults with Chronic Pain

Objectives:  This study was to develop a version of the Pain Medication Questionnaire (PMQ) specific to the elderly chronic pain population and to identify relevant subscales and items for that population. Exploratory factor analysis (EFA) was conducted to assess the factor structure of the PMQ, to eliminate items that are not appropriate for this population, and to improve ease of administration in the elderly population.
