This study had two primary objectives: (1) characterize the content of presleep cognitions of chronic pain patients and (2) evaluate the association between presleep cognitions and sleep disturbance. Thirty-one outpatients with benign chronic pain completed the Beck Depression Inventory, pain and sleep diaries and participated in an in vivo, presleep thought sampling procedure for 1 week in their homes. ⋯ Pain severity was found to be positively associated with Wake After Sleep Onset Time. These results are consistent with cognitive-behavioral models of primary insomnia and suggest the content of presleep cognitive arousal may contribute to sleep disturbance secondary to pain.
