BACKGROUND Although insomnia is a prevalent complaint with significant morbidity, it often remains unrecognized and untreated. Brief and valid instruments are needed both for screening and outcome assessment. This study examined psychometric indices of the Insomnia Severity Index (ISI) to detect cases of insomnia in a population-based sample and to evaluate(More)
STUDY OBJECTIVE Sleep related cognitions (e.g., faulty beliefs and appraisals, unrealistic expectations, perceptual and attention bias) play an important role in perpetuating insomnia. This paper presents new psychometric data on an abbreviated version of the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16), a 16-item self-report measure(More)
OBJECTIVE Although stress is often presumed to cause sleep disturbances, little research has documented the role of stressful life events in primary insomnia. The present study examined the relationship of stress and coping skills, and the potential mediating role of presleep arousal, to sleep patterns in good sleepers and insomnia sufferers. METHODS The(More)
Despite the elevated prevalence of insomnia in cancer patients, there is a lack of brief validated instruments for the evaluation of this particular problem in this population. The goal of this study is to empirically validate the Insomnia Severity Index (ISI) and to evaluate its ability to screen insomnia in 1670 cancer patients. The results support the(More)
Purpose Published cross-sectional studies have revealed that chemotherapy for breast cancer is associated with significant cognitive impairments. However, because these studies included no baseline assessment, it is unknown whether the cognitive impairments were pre-existent to cancer treatment or truly secondary to chemotherapy. To resolve this issue, this(More)
INTRODUCTION Despite the high prevalence of insomnia, there is little information about its incidence and risk factors. This study estimated the incidence of insomnia and examined potential risk factors in a cohort of good sleepers followed over a one-year period. METHODS Participants were 464 good sleepers who completed 3 postal evaluations over a(More)
PURPOSE Cross-sectional studies suggest that clinical insomnia is associated with immune downregulation. However, there is a definite need for experimental studies on this question. The goal of this randomized controlled study was to assess the effect of an 8-week cognitive-behavioral therapy (CBT) for chronic insomnia on immune functioning of breast cancer(More)
STUDY OBJECTIVES To estimate the prevalence of insomnia, describe clinical characteristics of sleep difficulties, assess the influence of cancer on the insomnia course, and identify potential risk factors involved in the development of insomnia among women who had received radiotherapy for non metastatic breast cancer. DESIGN A sample of 300 consecutive(More)
INTRODUCTION Although the fear of cancer recurrence (FCR) is to varying degrees almost universal in cancer survivors, few studies have been carried out specifically on this issue partly because of the complexity and the heterogeneity of the phenomenon. PURPOSE To explore the presence of specific profiles of FCR and to describe the nature of intrusive(More)
OBJECTIVE This population-based longitudinal study assessed the prevalence, incidence and evolution of fear of cancer recurrence (FCR) and its relationship with some cancer characteristics in a large sample of patients with mixed cancer sites over an 18-month period. METHODS A total of 962 patients scheduled to undergo surgery for cancer completed the(More)
