Background: Insomnia is a major cause of concern in the elderly with and without pain. This study set out to examine the insomnia and its correlates in a large sample of community adults aged ≥65â years. Methods: A cross-sectional postal survey was completed by 6205 older individuals (53.8% women; mean ageâ =â 76.2â years; SDâ =â 7.5). The participants also completed the Insomnia Severity Index (ISI) and questionnaires assessing pain intensity, pain spreading, anxiety, depression, and basic demographic information. The sample was divided into three groups based on the presence and duration of pain: chronic pain (CP; nâ =â 2790), subacute pain (SP; nâ =â 510), and no pain (NP; nâ =â 2905). Results: A proportion of each of the groups had an ISI score of 15 or greater (i.e., clinical insomnia): CPâ =â 24.6%; SPâ =â 21.3%; and NPâ =â 13.0%. The average scores of ISI differed significantly among CP, SP, and NP groups (pâ
