A Tool to Assess Participation in People With COPD: Validation of the Late Life Disability Instrument.

摘要: Background Participation in life roles is a critical patient-centered health outcome associated with morbidity and mortality older adults, but it not measured routinely people COPD. We aimed to validate participation measure, the Late Life Disability Instrument (LLDI), Research Question To what extent does LLDI demonstrate test-retest measurement error reliability, internal consistency, construct face validity, floor or ceiling effects when applied COPD? Study Design Methods In this cross-sectional study, scores were compared on measures of theoretically related constructs between groups based symptom severity, prognosis, frailty. A subsample (n = 36) completed second time over phone within one week. Participants health-care professionals asked about relevance, comprehensiveness, comprehensibility LLDI. Floor explored, consistency (Cronbach’s α) was calculated. Results Ninety-six adults COPD participated. The frequency limitation domains showed excellent reliability (two-way random effect intraclass correlation coefficient, 0.90 [standard measurement, 1.74 points] 3.16 points], respectively). Both fair correlations physical function, depression, quality (r = 0.38-0.59). relationship anxiety poor for domain −0.21) −0.45). discriminated different frailty (P ≤ .026). Neither effects, Cronbach’s α 0.69 0.91 domains, respectively. All healthcare most participants agreed that (79%) items relevant (81%). Interpretation shows validity can be used assess population.
