Quality of life assessment in individuals with lung cancer: Testing the Lung Cancer Symptom Scale (LCSS)

摘要: This paper presents the continued development and multi-institutional testing of an instrument focusing on measuring physical functional dimensions quality life. It emphasises evaluation symptoms associated with lung cancer their effect activity status. The Lung Cancer Symptom Scale (LCSS) is a disease- site-specific which has both patient observer (health care professional) form. scale required 8 min to administer 2 min. readability index was second-grade level for ninth-grade scale. Content validity revealed mean 96% agreement all major among 52 experts surveyed (confidence interval = 86-99%, P 0.05). 69 patients non-small cell small confirmed that matched experiences. Interrater reliability showed consistency items but one 21 raters at eight institutions; item consistent 20 raters. Similar results were found 9-month replication. Using Kappa statistic estimate extent repeated interrater reliability, almost perfect obtained (mean coefficients, 0.95-0.98). same rule as (+/- category) intrarater 95-100% Past test re-test indicated high reproducibility (r > 0.75, < 0.01 items). We conclude (1) LCSS demonstrates good feasibility, content validity, (2) indicates utility in multicentre trials, (3) internal consistency, construct criterion-related warranted.
