Evaluation of sleep disorders in cancer patients based on Pittsburgh Sleep Quality Index

Abstract

Insomnia, poor sleep quality and short sleep durations are the most common problems seen in cancer patients. More studies are needed about sleep disorders in cancer patients. In our study, we aimed to investigate the prevalence of sleep disorders and the impact of these problems on the quality of life in cancer patients. Pittsburgh Sleep Quality Index (PSQI) was given to a total of 314 patients. The psychometric evaluation of the Turkish version of PSQI in cancer patients revealed that 127 (40.4%) patients had global PSQI scores >5, indicating poor sleep quality. There was no statistically significant relationship between PSQI scores and sexuality, marital status, cancer stage and chemotherapy type (P > 0.05); while the patients with bone and visceral metastasis had much lower PSQI scores (P = 0.006). Patients with Eastern Cooperative Oncology Group performance scores of 3 or more had also significantly lower PSQI scores (P = 0.02). In conclusion, PSQI questionnaire may be used to evaluate the sleep disorders in cancer patients. Consistent use of multi-item measures such as PSQI with established reliability and validity would improve our understanding of difficulties experienced by cancer patients with chronic insomnia.

Associations among menopausal symptoms, sleep and fatigue in Taiwanese women with endometrial cancer

“…We found that the majority of participants with endometrial cancer had global PSQI scores >5 (54.7%), indicating difficulties in overall sleep quality, unlike previous findings (Akman, Yavuzsen, Sevgen, Ellidokuz, & Yilmaz, ; Wu et al., ). Among Turkish people with mixed cancers, only 40% reported poor sleep quality (Akman et al., ). In contrast, 90% of US breast cancer patients with CRF (≥6 of 13 fatigue symptoms) had poor sleep quality (Wu et al., ).…”

A Pilot Mobile-Based Mindfulness Intervention for Cancer Patients and Their Informal Caregivers

“…The 19-item Pittsburg Sleep Quality Index (PSQI) assesses sleep quality by asking a series of questions about sleep quality during the past month (Akman, Yavuzsen, Sevgen, Ellidokuz, & Yilmaz, 2015). A global score (ranging 0 to 21) is calculated based on the seven domain scores, with a higher score indicating poorer sleep quality.…”

“…yang berdampak langsung pada kondisi fisik dan psikologis pasien, termasuk kualitas tidurnya. Akman et al (2015) telah membuktikan kondisi tersebut dan didapatkan data bahwa kebutuhan istirahat pasien terganggu dan kualitas tidurnya dinyatakan buruk.…”

“…Gangguan tidur sendiri merupakan salah satu masalah fisik yang dialami akibat kanker payudara. Menurut Akman et al (2015), gangguan tidur diketahui memengaruhi kualitas hidup dan psikologis penderita kanker. Gangguan tidur seperti nyeri dapat membangunkan seseorang dari tidur biasanya, mencegah untuk tertidur, dan berkontribusi terhadap hilangnya energi atau kelelahan.…”
