Examination of Age Variations in the Predictive Validity of Self-Rated Health.

ABSTRACT:

Objectives

The high predictive validity of self-rated health (SRH) is a major strength of this widely used population health measure. Recent studies, however, noted that the predictive validity varies across population subgroups. The aim of this study is to examine respondents' age as a moderator of SRH predictive validity with respect to subsequent mortality risk.

Method

Using data from the National Health Interview Survey-Linked Mortality Files (NHIS-LMF) 1986-2006, we estimate Cox proportional hazard models of all-cause and cause-specific mortality for adults aged 45-84 years as a function of their health ratings (N = 574,008).

Results

The data show significant age moderation of the predictive validity of SRH across all levels of ratings: the hazard ratios for mort
