Although insomnia is a prevalent complaint with significant morbidity, it often remains unrecognized and untreated. Brief valid instruments are needed both for screening outcome assessment. This study examined psychometric indices of the Insomnia Severity Index (ISI) to detect cases in population-based sample evaluate treatment response clinical sample. Participants were 959 individuals selected from community an epidemiological (Community sample) 183 evaluated 62 controls without (Clinical...
Study Objective:Sleep related cognitions (e.g., faulty beliefs and appraisals, unrealistic expectations, perceptual attention bias) play an important role in perpetuating insomnia. This paper presents new psychometric data on abbreviated version of the Dysfunctional Beliefs Attitudes about Sleep Scale (DBAS-16), a 16-item self-report measure designed to evaluate subset those sleep cognitions.
Cognitive behavioral therapy (CBT) and hypnotic medications are efficacious for short-term treatment of insomnia, but few patients achieve complete remission with any single treatment. It is unclear whether combined or maintenance therapies would enhance outcome.To evaluate the added value medication over CBT alone acute insomnia effects on long-term outcome.Prospective, randomized controlled trial involving 2-stage 160 adults persistent treated at a university hospital sleep center in...

Purpose Chronic insomnia is highly prevalent in cancer patients. Cognitive-behavioral therapy (CBT) considered the treatment of choice for chronic primary insomnia. However, no randomized controlled study has been conducted on its efficacy secondary to cancer. Using a design, this among breast survivors evaluated effect CBT sleep, assessed both subjectively and objectively, hypnotic medication use, psychological distress, quality life.

Despite the high prevalence of insomnia, there is little information about its incidence and risk factors. This study estimated insomnia examined potential factors in a cohort good sleepers followed over one-year period.
<h3>Background</h3> Despite its high prevalence, little information is available about the natural history of insomnia. The extent to which episodes insomnia will persist or remit over time difficult predict. We examined and describe most common trajectories 3 years. <h3>Methods</h3> Three hundred eighty-eight adults (mean [SD] age, 44.8 [13.9] years; 61% women) were selected from a larger population-based sample on basis presence at baseline. They completed standardized sleep/insomnia...
Despite the elevated prevalence of insomnia in cancer patients, there is a lack brief validated instruments for evaluation this particular problem population. The goal study to empirically validate Insomnia Severity Index (ISI) and evaluate its ability screen 1670 patients. results support internal consistency temporal stability ISI. Its two-component factor structure clear stable between different diagnoses. construct validity that instrument also supported by correlations obtained with...
To estimate the prevalence of insomnia, describe clinical characteristics sleep difficulties, assess influence cancer on insomnia course, and identify potential risk factors involved in development among women who had received radiotherapy for non metastatic breast cancer.A sample 300 consecutive been treated with first completed an screening questionnaire. Participants reported difficulties were subsequently interviewed over phone to evaluate further nature, severity, duration, course their...
Purpose This study aimed to assess the prevalence and natural course (incidence, persistence, remission, relapse) of insomnia comorbid with cancer during an 18-month period. Patients Methods All patients scheduled receive a curative surgery for first diagnosis nonmetastatic were approached on day their preoperative visit participate in study. A total 962 (mixed sites) completed diagnostic interview at perioperative phase (T1), as well 2 (T2), 6 (T3) 10 (T4), 14 (T5), 18 (T6) months after...

BACKGROUND Insomnia affects between 30% to 60% of patients with cancer but the authors' knowledge little is known regarding factors associated its development. It has been postulated that adjuvant treatments and their side effects could trigger sleep disturbances in this population empirical evidence lacking. The goal current study was assess, separately breast prostate cancer, effect on evolution insomnia symptoms mediating role somatic symptoms. METHODS As part a population‐based...
Insomnia is a significant public health problem, but there little information on its natural history.To assess the incidence, persistence, and remission rates of insomnia over 5-year naturalistic follow-up period.This cohort study included participants with without sleep problems selected from adult population in Canada August 2007 to June 2014. Participants completed an annual survey about their status for 5 consecutive years.Using validated algorithms, were classified at each assessment as...

Ten participants were enrolled in treatment protocol multiple-baseline design. Intervention time series analyses daily sleep diary data revealed significant improvements efficiency and total wake time. These results corroborated by polysomnographic data. In addition, insomnia was associated with mood, general physical fatigue, global cognitive...
