Sleep should not be this difficult: An interpretive descriptive study of older adults' perspectives on behaviour change elements in Sleepwell and experiences with benzodiazepine discontinuation.

Benzodiazepine receptor agonists are often used for insomnia in older adults contrary to current evidence. The harms outweigh the benefits, which are limited. Cognitive behavioural therapy for insomnia is the first-line recommended treatment. Sleepwell was created as a repository of evidence-based resources to promote cognitive behavioural therapy for insomnia and limit benzodiazepine receptor agonist use. This qualitative study uses an interpretive description design and reflexive thematic analysis to explore older adults' perspectives on behavioural change techniques used in Sleepwell resources. It also explores challenges and opportunities towards benzodiazepine receptor agonist discontinuation and cognitive behavioural therapy for insomnia use. Participants were recruited from the Sleepwell arm of a randomized controlled trial. Data were collected from 15 older adults using semi-structured interviews. Two main themes were developed: (1) sleep should not be this difficult; and (2) whether you know it, or learn it, drugs are bad. Two sub-themes were created within the first theme: (1) justification of benzodiazepine receptor agonist use to achieve sleep goals; (2) efforts of committing to cognitive behavioural therapy for insomnia. Several behavioural change techniques (e.g. information about consequences, anticipated regret, salience of consequences) were enablers of benzodiazepine receptor agonist-related behaviour change. For committing to cognitive behavioural therapy for insomnia, several behavioural change techniques (e.g. self-monitoring of behaviour, distraction, stimulus substitution) were beneficial, but social support, which was perceived as useful, was absent. Older adults experienced tension with benzodiazepine receptor agonist use and deprescribing, despite knowing or learning the potential consequences of benzodiazepine receptor agonists. Cognitive behavioural therapy for insomnia implementation was challenging. Embedded behavioural change techniques in the Sleepwell booklets were identified as helpful, but more (e.g. social support) are needed to optimize cognitive behavioural therapy for insomnia use.
