概要	The Brief Pain Inventory (BPI) is a concise, validated self-report instrument developed by Cleeland and Ryan beginning in 1994 to measure the severity and functional impact of pain in patients with cancer and chronic pain conditions. The BPI-Short Form comprises 11 items assessing pain severity and interference with daily activities, enabling rapid multidimensional pain assessment across diverse clinical populations.	The Pittsburgh Sleep Quality Index (PSQI) is a comprehensive self-report questionnaire developed by Buysse and colleagues in 1989 to assess sleep quality and sleep disturbances. The PSQI comprises 19 items aggregated into seven components that evaluate sleep duration, sleep efficiency, sleep disturbances, daytime dysfunction, and use of sleep medications. It is one of the most widely used instruments for both clinical sleep assessment and sleep research.
