Disturbed sleep is common among breast cancer patients (Davidson, MacLean, Brundage, & Schulze, 2002;Koopman, Nouriani et al, 2002;Savard & Morin, 2001) and has been found to be associated not only with poor quality of life (Carpenter & Andrykowski, 1998;Fortner, Stepanski, Wang, Kasprowicz, & Durrence, 2002), depressive symptoms (Koopman, Nouriani et al, 2002), and fatigue (Lichstein, Means, Noe, & Aguillard, 1997), but also with increased breast cancer risk (Davis, Mirick, & Stevens, 2001). Rates of sleep disturbance for women with breast cancer are well above those for the general adult population and higher than the above average rates for cancer patients in general.…”

Objective-Sleep disturbances are common among women with breast cancer and can have serious consequences. The present study examined depression, pain, life stress, and participation in group therapy in relation to sleep disturbances in a sample of women with metastatic breast cancer.Methods-Ninety-three women with metastatic breast cancer participated in a large intervention trial examining the effect of the group therapy on their symptoms. They completed measures of depression, pain, life stress, and sleep disturbance at baseline, 4, 8 and 12 months. Results-The results showed that higher initial levels of depression at baseline predicted problems associated with getting up in the morning, waking up during the night, and daytime sleepiness. Increases in depression over the course of 12 months were associated with fewer hours of sleep, more problems with waking up during the night and more daytime sleepiness. Higher levels of pain at baseline predicted more problems getting to sleep. Increases in pain predicted more difficulty getting to sleep and more problems waking up during the night. Greater life stress at baseline predicted more problems getting to sleep and more daytime sleepiness.Conclusions-Depression, pain, and life stress scores were each associated with different types of negative change in self-reported sleep disturbances. Depression, especially worsening depression, was associated with the greatest number of types of negative change. The relationships found between sleep disturbance and depression, pain, and life stress suggest specific ways to address the problem of sleep disturbance for women with metastatic breast cancer and show how different types of disturbed sleep may be clinical markers for depression, pain, or life stress in this population.Keywords sleep disturbance; metastatic breast cancer; pain; depression; stressful life events Corresponding Author: Oxana G.

“…The PSQI consists of 19 items from which 7 component scores are derived: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. Although a total score of ≥ 5 indicates poor sleep [25], studies suggest that a cut-off of 8 is more appropriate for cancer survivors [26].…”

Identifying the subtypes of cancer-related fatigue: results from the population-based PROFILES registry

Purpose Little research has been done to identify possible cancer-related fatigue (CRF) subtypes and to classify cancer survivors accordingly. We aimed to identify CRF subtypes in a large population-based sample of (long term) stage I-III colorectal cancer survivors. We also identified factors associated with the CRF subtypes. Methods Respondents completed the Multidimensional Fatigue Inventory and other validated questionnaires on anxiety and reduced positive affect (anhedonia), sleep quality, and lifestyle factors (body mass index and physical activity). Latent class analysis was used to derive the CRF subtypes.Factors associated with the derived CRF subtypes were determined with multinomial logistic regression. Results Three CRF classes were identified: class 1 (no fatigue and distress, n = 644, 56%), class 2 (low fatigue, moderate distress, n = 256, 22%), and class 3 (high fatigue, moderate distress, n = 256, 22%). Multinomial logistic regression results show that survivors in class 3 were more likely to be female, were treated with radiotherapy, have comorbid diabetes mellitus, and be overweight/obese than survivors in class 1 (reference). Survivors in classes 2 and 3 were also more likely to have comorbid heart condition, report poorer sleep quality, experience anhedonia, and report more anxiety symptoms when compared with survivors in class 1. Conclusions Three distinct classes of CRF were identified which could be differentiated with sleep quality, anxiety, anhedonia, and lifestyle factors. Implications for cancer survivors The identification of CRF subtypes with distinct characteristics suggests that interventions should be targeted to the CRF subtype.

“…In clinical populations PSQI sum scores greater than eight indicate a poor sleep quality or sleep disturbance. 18 The overall internal consistency is Cronbach's a ¼ 0.83. 17 The German version of the PSQI has been validated in patients with primary insomnia and shows a sensitivity of 98.7%, a specificity of 84.4%, a test-retest reliability of 0.87 and Cronbach's a ¼ 0.85.…”

Recent research has shown that patients undergoing hematopoietic SCT (HSCT) experience multiple symptoms that can affect the sleep quality adversely. This study investigated the sleep quality of patient in the acute course of HSCT, and measured the impact of sociodemographic, medical, physical and psychological factors. Fifty patients were assessed before admission, 44 participated during inpatient treatment and 32 on day 100 ( ± 20) posttransplantation. Measuring instruments included the Pittsburgh Sleep Quality Index (PSQI) and a sleep diary (sleep quality), the European Organization for Research and Treatment of Cancer Quality of Life QuestionnaireCore 30 (health-related quality of life), the Hospital Anxiety and Depression Scale -German version (anxiety/depression) and the German version of the Cancer and Treatment Distress Scale (treatment-specific distress). The prevalence of sleep disturbances was 32% before admission, 77% during the hospital stay and 28% after discharge. Difficulty in maintaining sleep was the most intense sleep problem during the inpatient phase. This was mainly caused by disturbing noises and need to use the bathroom frequently. Sleep problems were significantly worse during the hospital stay compared with the other measurement points in time (Po0.001). A significant interaction was seen between the time course of sleep disturbances and the type of transplantation (P ¼ 0.001). The findings suggest that sleep disturbances after HSCT are particularly associated with physical functioning, fatigue and treatment-specific distress, and factors that contribute to sleep difficulties in the general population seem to be less important.
