Quality of life (QoL or QOL) is categorized as a health outcome alongside metrics like disability-adjusted life years (DALYs) and quality-adjusted life years (QALYs) in research on diseases such as cancer and cardiovascular conditions research team health categories. It is commonly measured using validated scales, including the WHO Quality of Life-Brief version (WHOQOL-BREF), a 26-item instrument derived from the original WHOQOL WHOQOL-BREF scale description, and the Pediatric Quality of Life Inventory (PedsQL) PedsQL sleep association. Numerous studies link poor sleep quality or disruption to diminished QoL across populations, including healthy adults short-term sleep consequences, maternal caregivers of children with bronchopulmonary dysplasia maternal caregivers sleep QoL, dialysis patients with restless legs Unruh et al. dialysis study, and autistic individuals from adolescence to adulthood, where mental health and sleep quality predict QoL according to Lawson et al. (2020) Lawson et al. autism predictors. Psychological factors like secure attachment enhance QoL secure attachment QoL link, while anxiety disorders, depression, and chronic pain reduce it anxiety disorders QoL impact. Interventions such as traditional cognitive behavioral therapy (CBT) improve QoL, depression, and anxiety in patients with chronic pain and distress, per systematic reviews CBT systematic review benefits, though mindfulness-based interventions (MBIs) show mixed results MBI vs TAU QoL effects. The autistic community emphasizes prioritizing QoL improvements autistic community QoL emphasis, and QoL overlaps with well-being concepts like life satisfaction well-being QoL synonyms. Studies by Hirano et al. (2022), Celik et al. (2012), and others explore QoL predictors in students, caregivers, and workers during stressors like COVID-19 or dialysis.

Quality of life (QOL), often abbreviated as such in medical studies, is a multi-dimensional construct frequently assessed in cancer patients and survivors, encompassing physical, psychological, social, and environmental domains. In breast cancer contexts, QOL typically improves post-treatment; for instance, in a longitudinal study of 143 patients at Guangdong Provincial People’s Hospital, mean QOL scores rose from 87.77 at baseline to 93.42 at 12 months post-discharge, stabilizing through 48 months QOL increased to 93.42 at 12 months QOL stable after 12 months. However, factors like fear of cancer recurrence (FCR), prevalent among long-term survivors, correlate with poorer QOL alongside depression and anxiety, as noted by Koch et al. FCR associated with poorer QOL. Pain significantly compromises QOL, especially in advanced breast cancer, per Costa et al. pain compromises breast cancer QOL, while chemotherapy induces a fatigue-depression-anxiety cluster leading to QOL declines chemotherapy symptom cluster lowers QOL. Surgical choices matter: meta-analyses by Ng ET et al. and others show better QOL after lumpectomy versus mastectomy due to improved body image and fewer side effects better QOL post-lumpectomy, echoed by Marinkovic et al. and Han et al. Long-term effects like lymphedema and symptoms (fatigue, sleep issues) also impair QOL lymphedema affects mobility and QOL. Improving QOL demands personalized interventions, survivorship care plans, and comprehensive approaches, as emphasized for cancer survivors personalized interventions needed. Dyadic coping positively influences QOL in oncological dyads dyadic coping boosts QOL. Studies like Bloom JR et al. highlight multi-dimensional QOL in long-term survivors multi-dimensional QOL studied. Notably, chemotherapy and radiotherapy showed no long-term QOL impact in the Guangdong study no long-term treatment impact.

Quality of life (QoL) is frequently assessed as a key outcome in breast cancer treatment studies, particularly comparing surgical options like mastectomy versus breast-conserving surgery or lumpectomy. For instance, Chow R et al. examined mastectomy vs lumpectomy QoL, Ng ET et al. meta-analysis on surgery QoL, Hanson SE et al. long-term QoL post-surgery, and Tarkowska M et al. 5-year QoL functioning highlight this focus. Additional factors impacting QoL include radiodermatitis during radiotherapy radiodermatitis impacts breast cancer QoL, postoperative radiotherapy effects on anxiety and depression Parvizi M et al. radiotherapy QoL effects, treatment side effects on return to work side effects influence return to work QoL, mastectomy's influence on body image mastectomy affects QoL body image, aesthetic outcomes post-conservation aesthetic outcome affects psychosocial QoL, and associations with anxiety, depression, and social support per Ng CG et al. prospective study. Broader evidence shows psychological interventions improve QoL in early-stage cancer patients according to Bognar et al. 2024 meta-analysis, while a colorectal cancer meta-analysis reported low effects colorectal survivors QoL meta-analysis. A 2025 BMC Cancer study by unnamed authors explores cancer treatments' long-term psychological and QoL impacts 2025 BMC Cancer treatments QoL study.
