Self-Assessed Health into Late Adulthood

Abstract. Self-assessed health (SAH) is the personal assessment of one’s own health ( Idler & Benyamini, 1997 ; Jylhä, 2009 ). It is often measured using a single item asking whether adults rate their health as excellent, very good, good, fair, or poor. When measured at a single point in time, SAH relates to a variety of short-term and long-term health outcomes and behaviors, including morbidity, healthcare utilization, and mortality ( Benyamini, 2008 ; Mossey & Shapiro, 1982 ; Westerhof & Wurm, 2015 ). Recently, attention has shifted away from examining SAH at a single point in time toward understanding whether SAH trajectories can better predict health outcomes ( Ayyagari et al., 2012 ; Schmitz et al., 2013 ). Therefore, it is critical to understand the factors contributing to the SAH process. This article provides a multidisciplinary overview of SAH and SAH change while illustrating the benefits of adopting a lifespan approach in future research. The current SAH literature, including cross-sectional and longitudinal studies, is used to examine what is known about the SAH process into late adulthood. From the literature, it is clear SAH is a multidimensional construct, susceptible to age-related change and sociohistorical contexts. Understanding the developmental mechanisms and multiple influences underlying change, however, may help further the use of SAH as a life-long health-promotion tool. Lifespan concepts are applied to expand discussion and recommendations are made concerning the application of alternative variables and methodologies. Future studies of SAH should consider these personal perceptions of health not only as predictors of health outcomes in later life, but also as tools for effective health promotion in everyday life.
