title: [Validation of interviewer administration of the Short Form 36 Health Survey, and comparisons of health-related quality of life between community-dwelling and institutionalized elderly people].
abstract: The Short Form 36 Health Survey (SF-36) is a questionnaire that is widely used to measure health-related quality of life. Because self-administered questionnaires may not be appropriate for seriously ill or elderly people, we administered the SF-36 to institutionalized elderly people by face-to-face interviews, and tested its reliability and validity. We also compared the SF 36 score of those subjects with the scores of community-dwelling elderly people. We studied 117 people aged 65 or over who were living in residential facilities on Sado island and 62 randomly sampled elderly people who were living in the community. The SF-36 scores of the institutionalized subjects had acceptable ceiling and floor effects, and their internal consistency, concurrent validity, and construct validity were high. The only exceptions were the scores of the "vitality" subscale. Adjusted mean scores on four subscales were higher among the institutionalized subjects than among those living in the community: role limitation due to physical condition, role limitation due to emotional condition, social functioning, and bodily pain. The two groups did not differ with regard to scores on the "mental health" scale, the "vitality" scale, or the "general health perception" scale. We conclude that the SF-36 can be useful for measuring health-related quality of life among institutionalized elderly people, if it is administered in face-to-face interviews.
