Does Harvey's (2002) Cognitive Model of Insomnia Predict Sleep Disturbance Among Older Adults with Mental Health Problems?

Previous research has identified an increased incidence of insomnia among older adults, and among adults with mental health difficulties. Harvey’s (2002) cognitive model of insomnia asserts that insomnia will be predicted by negative cognitive activity, dysfunctional beliefs about sleep and counter-productive safety behaviours. The applicability of the model to the insomnia experiences of older adults with mental health difficulties was examined using self-report questionnaires. Correlational analyses demonstrated significant relationships between each of the variables investigated, which were consistent with the model. Implications for Harvey’s model, including the observed influence of worry as an important safety behaviour and the importance of considering the roles of physical tension and individual beliefs about sleep, and treatment recommendations are discussed
