Abstract Objective To assess how well the SF-36 a well-validated generic quality of life QOL instrument compares with its shorter adaptation the SF-12 in capturing differences in QOL among patients with and without obesity. Methods We compared the correlation between the physical PCS and mental MCS component summary measures of the SF-12 and SF-36 among 356 primary care patients using Pearson coefficients r and conducted linear regression models to see how these summary measures captures the variation across BMI. We used model R2 to assess qualitatively how well each measure explained the variation across BMI. Results Correlations between SF-12 and SF-36 were higher for the PCS in obese r compared to overweight r and normal weight patients r p but were similar for the MCS across BMI. Compared to normal weight patients obese patients scored points lower on the PCS-12 and points lower on the PCS-36 after
