对健康状况的自我评价已被证明可以预测死亡率，其作用超过了基于健康问题、身体残疾和生物或生活方式风险因素的指数对预测的贡献。 这种关联的几个可能的原因进行了讨论：（a）以前的研究方法的缺陷，使虚假的关联;（B）其他心理社会影响的死亡率参与和解释的关联;和（c）健康状况的自我评价有自己的直接和独立的影响。 来自耶鲁健康与老龄化项目（N = 2812）的4年随访死亡率数据用于探索这些可能性。 分析控制了健康问题、残疾和风险因素的众多指标的贡献，并对复杂的抽样设计的标准误差进行了调整。 研究结果有利于第三种可能性，一个独立的效果，在某种程度上，特定的一组心理社会因素检查没有解释的基本关联，并在一定程度上，控制变量是一个足够全面的设置。
Self-evaluations of health status have been shown to predict mortality, above and beyond the contribution to prediction made by indices based on the presence of health problems, physical disability, and biological or life-style risk factors. Several possible reasons for this association are discussed: (a) methodological shortcomings of previous studies render the association spurious; (b) other psychosocial influences on mortality are involved and explain the association; and (c) self-evaluations of health status have a direct and independent effect of their own. Four-year follow-up mortality data from the Yale Health and Aging Project (N = 2812) are used to explore these possibilities. The analysis controls for the contribution of numerous indicators of health problems, disability and risk factors, and also makes adjustments of standard errors for the complex sample design. The findings favor the third possibility, an independent effect, to the extent that the particular set of psychosocial factors examined did not explain the basic association, and to the extent that the control variables were an adequately comprehensive set.
