The effect of mode of administration on medical outcomes study health ratings and EuroQol scores in AIDS.

摘要: Brief measures of health-related quality life are being used with increased frequency in AIDS clinical trials. Self-administration questionnaires can reduce costs this setting because they require little time. However, the equivalence between self- and interview-administered responses trials is not known. We evaluated patient proxy to Medical Outcomes Study HIV Health Survey (MOS-HIV) EuroQol. randomized 68 patients advanced disease on (1) mode administration (self vs. interview); (2) type interview (face-to-face telephone); (3) questionnaire order (MOS-first EuroQol-first); (4) 2- 3-item response categories for physical limitations. There were few differences scores self interview. Proxy respondents viewed as more impaired than did themselves subjective aspects health including mental (63.8 75.7, p < 0.001), distress (67.3 77.1, p=0.007), pain (64.4 70.0, p=0.04), vitality (48.4 55.5, p=0.04). Results concerning number conclusive. Our results suggest that disease, data from MOS-HIV EuroQol collected using different modes may be pooled, but should calibrated.
