| Résumé : | [BDSP. Notice produite par INIST WR0xAba3. Diffusion soumise à autorisation]. A large amount of information in the 1990 Ontario Health Survey (OHS) was collected from proxy respondents using questions administered in face-to-face interviews. Can this of information represent candid self-reported measures of health status ? Inter-rater agreement was assessed using Cohen's kappa statistics for responses to questions that were answered both by individuals about themselves anti by proxies on their behalf intra-rater agreement, assessing the effect of mode of survey administration (in-person interviews versus, self-completed written questionnaires) on the responses, was also investigated using the kappa statistic. We conclude that : (1) proxy responses in the OHS for impairments of emotion and pain are not reliable indicators of self-response (kappa<0.32) because proxy respondents consistently under-report the burden of morbidity ; (2) levels of morbidity reported by subjects to interviewer-administered questionnaires may underestimate morbidity, relative to morbidity reported by subjects using self-administered questionnaires completed in privacy. We also hypothesize that the relative magnitudes of inaccuracy introduced by interviewer administration relative to proxy reporting depends on the phenomenon being measured. When assessing pain, mode of administration is quantitatively a more important source of disagreement than type of respondent. |
