Predictors of Interest in Psychological Treatment for Insomnia Among Older Primary Care Patients With Disturbed Sleep

In this study, we examined whether the common sense model of illness representation (CSMIR) could be successfully used to predict interest in cognitive-behavioral treatment for insomnia (CBT-I) among older primary care patients with disturbed sleep. The Sleep Impairment Index (C. M. Morin, 1993) was used to assess sleep disturbance and the constructs of the CSMIR in primary care patients ages 55 and older. Statistical analyses showed that the CSMIR constructs of consequences (perceived adverse consequences of sleep disturbance to functioning), causes (attributing one's insomnia to bad sleeping habits), and emotion (concern about one's sleep problem) predicted interest in CBT-I. These data provided encouraging support for the ability of the CSMIR to accurately predict patient interest in treatment for insomnia. Implications for assessment and treatment of insomnia in primary care are discussed.
