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.

The present study was designed to examine the relationship between unconventionality and marijuana use over time. The sample for this paper consisted of 532 male and female participants interviewed during early adolescence, late adolescence, their early twenties, and their late twenties. ⋯ The findings indicated that (1) the influence of initial unconventionality (T2) on initial marijuana use (T2) was stronger for males, (2) unconventionality at T2 was not significantly related to overall rate of growth in marijuana use, and (3) change in unconventionality was related to overall growth rate of marijuana use. The implications of the findings for prevention and treatment are discussed.

Previous studies with undergraduates have provided support for the reliability and oblique three-factor structure of a new scale, the Pain Catastrophizing Scale (PCS). We examined the reliability and validity of the PCS in adult community and pain outpatient samples. The PCS showed a high internal consistency in both groups. ⋯ The analyses also showed significant differences between the community and the outpatient samples on the PCS total and subscales. Overall, the results showed strong evidence of criterion-related, concurrent, and discriminant validity for the PCS in the community sample. Limitations of the present study are discussed.

This study was designed (1) to characterize the extent and nature of sleep complaints of chronic pain patients and (2) to examine the factors that predict sleep quality. A heterogeneous sample of 51 outpatients with benign, chronic pain was recruited from newspaper and pain clinic advertisements. ⋯ Sleep complaints were reported by 88% of the sample. Presleep cognitive arousal, rather than pain severity, was found to be the primary predictor of sleep quality.

Comparative Study
Prognostic factors and treatment-related changes associated with return to work in the multimodal treatment of chronic back pain.
The goals of the current study were to determine those preprogram (= prognostic) variables and treatment-related changes that predict return to work in the multimodal management of chronic back pain. The outcome measures for 143 patients at 6-month follow-up were analyzed. The program had a duration of 4 weeks, was based largely on the functional restoration approach (Mayer and Gatchel, 1998), and occurred within a workers' compensation framework. ⋯ A repeated-measures MANOVA showed an incomplete return to work to be associated with only limited improvement in self-reported disability and pain report. However, patients who failed to return to work did not differ with regard to improvement in objective physical functioning or psychological distress. It is therefore hypothesized that a change in the perceived disability status is the key element necessary to return patients with chronic back pain to work, although ongoing reinforcement schemes operative in the home/work environment may lead to a relapse in the posttreatment phase.
