共回归模型研究了17个心理功能指标（智力、个性、主观幸福感和社会关系）与死亡率之间的关系。样本（N = 514，年龄范围70-103岁）包括1990年至1993年评估的柏林老龄化研究的参与者。11个指标被确定为零阶水平的死亡率风险因素，6个指标被确定为控制年龄的死亡率风险因素。在控制了年龄、社会经济地位、健康和其他16个心理因素后，感知速度慢和对衰老的不满是唯一显著的。70-84岁的人智力功能低下的风险比最老的老人（85岁以上）更大。心理风险因素的影响并没有随着时间的推移而减少。未来的研究应该集中在机制和时间框架，死亡相关的智力功能和自我评价的基础。
Con regression models examined associations between 17 indicators of psychological functioning (intellectual abilities, personality, subjective well-being, and social relations) and mortality The sample (N = 514 age range 70-103 years) comprised participants in the Berlin Aging Study assessed between 1990 and 1993, By 1996 50% had died. Eleven indicators were identified as mortality risk factors at the zero-order level and six when age was controlled. Low perceptual speed and dissatisfaction with aging were uniquely significant after controls for age, SES, health, and the 16 other psychological factors. Low intellectual functioning was a greater risk for individuals aged 70-84 years than for the oldest old (over 85 years). The effects of psychological risk factors did not diminish over time. Future research should focus on the mechanisms and time frames that underlie the death-relatedness of intellectual functioning and self-evaluation.
