Abstract

ObjectiveThis study examines the five-year stability of the association of SF-12 and SF-6D scores with scores on the longer SF-36 and its domains in community-dwelling older men and women.

MethodsParticipants were 653 men and 917 women aged 50 and older who completed mailed surveys of HRQOL 1995, 2000. SF-36 physical PCS and mental MCS component scores, domain scores; SF-12 PCS and MCS scores; and SF-6D scores were computed.

ResultsAverage age in 1995 was 68.2 ± 10.7 for men and 69.8 ± 11.3 for women. In 1995 and 2000, men had significantly higher scores on all measures P’s < 0.001. Sex-specific Pearson correlations of SF-12 PCS and MCS scores with SF-36 PCS and MCS scores ranged from 0.91 to 0.97 P’s < 0.000. Health utility scores SF-6D were also associated with SF-36 PCS and MCS scores, but correlations were lower, ranging from 0.61 to 0.79 P’s < 0.000. Age-stratified comparisons of 5-year change scores for SF-36 PCS showed significant declines in physical health for both men and women within all four age-groups 50–59, 60–69, 70–79, 80+ with steepest declines in the oldest age-group age 80+. Over time, mental health scores showed significant modest improvement in the younger age-groups but declines in men >70 and women >80 years. The SF-6D scores improved somewhat for the youngest men and women but mean change scores declined for the other age-groups.

ConclusionSimilar conclusions would result using either instrument SF-12 or SF-36. However, SF-6D and SF-36 assess, at least in part, different underlying aspects of HRQOL. Both age and sex impact HRQOL.

KeywordsHealth-related quality of life Physical and mental functioning Aging All three authors have contributed to the conception and design of the work and data analysis plan, interpretation of the data, and preparing the manuscript for publication. The second and third authors were in charge of the acquisition of subjects. The first author conducted the data analysis and wrote the first draft which was revised by the second and third authors. All authors were involved with the data in a manner substantial enough to take public responsibility for it. All authors believe the manuscript represents valid work and have reviewed the final version of the manuscript and approve of it for publication.
