SHORT FORM-36 (SF-36) HEALTH SURVEY QUESTIONNAIRE - NORMATIVE DATA FOR ADULTS OF WORKING AGE

Objectives-To gain population norms for the short form 36 health survey questionnaire (SF36) in a large community sample and to explore the questionnaire's internal consistency and validity. Design-Postal survey by using a booklet containing the SF36 and several other items concerned with lifestyles and illness. Setting-The sample was drawn from computerised registers of the family health services authorities for Berkshire, Buckinghamshire, Northamptonshire, and Oxfordshire. Sample-13042 randomly selected subjects aged 18-64 years. Main outcome measures-Scores for the eight health dimensions of the SF36. Results-The survey achieved a response rate of 72% (n=9332). Internal consistency of the different dimensions of the questionnaire was high. Normative data broken down by age, sex, and social class were consistent with those from previous studies. Conclusions-The SF36 is a potentially valuable tool in medical research. The normative data provided here may further facilitate its validation and use.
