Age-Related Item Nonresponse in Surveys of Recently Discharged Patients

Journal of Gerontology, 1992
We examined item nonresponse in questionnaires that assessed the physical functioning, emotional status, and satisfaction with care of surgical patients recently discharged from the hospital following coronary artery bypass graft surgery (CABG; N = 267), total hip replacement (THR; N = 283), and transurethral prostatectomy (TURP; N = 292).
