To select and validate a 12-item health survey (SF-12) capable of reproducing the physical and mental summary scores of the 36-item SF-36.
Applied regression methods to select 12 items from the SF-36 to reconstruct Physical Component Summary (PCS) and Mental Component Summary (MCS) scales in a general US population sample (n=2,333).
Cross-validated the derived scoring algorithms in the Medical Outcomes Study and evaluated 2-week test-retest reliability in a general population subsample (n=232).
Tested empirical validity across 20 cross-sectional and longitudinal criteria comparing groups differing in age, depression recovery, symptom severity, and 1-year health changes.
The SF-12 yielded multiple R² values of 0.911 for physical and 0.918 for mental summary scales in the general population, and cross-validated R² values of 0.905 and 0.938 in the Medical Outcomes Study.
Two-week test-retest correlations reached 0.89 for the 12-item physical score and 0.76 for the 12-item mental score.
Relative validity estimates ranged from 0.43 to 0.93 (median 0.67) for physical criteria and from 0.60 to 1.07 (median 0.97) for mental criteria compared to the best SF-36 scales, with slightly higher standard errors.
