Abstract

The study of health outcomes and its predictors remains a topic of great interest, and psychologists have long examined the connections between individual traits and health. This study focuses on the interaction between two core psychological traits—conscientiousness and general mental ability (GMA)—and their role in predicting health outcomes. This study tests a model in which conscientiousness and GMA interact to predict internal health locus of control (HLOC-I), which is subsequently associated with perceived health, body mass index, and blood pressure. The results suggest a moderated mediation process in which the relationship between conscientiousness and health outcomes is mediated by HLOC-I, and moderated by GMA such that the relationship between conscientiousness and health outcomes is lower for those higher in GMA. The results shed light on how personality and ability combine to predict health outcomes, and offers insight into the traits that potentially underlie HLOC-I, further highlighting the importance of stable, individual differences in determining salient health outcomes.

自觉性与健康结果：一般心理能力的调节作用和内部健康控制点的中介作用

对健康结果及其预测因素的研究仍然是一个备受关注的话题，心理学家长期以来一直在研究个体特质与健康之间的联系。本研究主要关注两个核心心理特质--自觉性和一般心理能力（GMA）--之间的相互作用及其在预测健康结果中的作用。本研究测试了一个模型，在该模型中，自觉性和一般心智能力相互作用，预测内部健康控制点（HLOC-I），而内部健康控制点随后与感知健康、体重指数和血压相关联。研究结果表明，自觉性与健康结果之间存在一个调节中介过程，即自觉性与健康结果之间的关系由 HLOC-I 中介，并由 GMA 调节，因此自觉性与健康结果之间的关系对于 GMA 较高的人来说较低。研究结果揭示了人格和能力是如何共同预测健康结果的，并提供了对可能成为 HLOC-I 基础的特质的见解，进一步强调了稳定的个体差异在决定突出的健康结果方面的重要性。

期刊介绍： Personality and Individual Differences is devoted to the publication of articles (experimental, theoretical, review) which aim to integrate as far as possible the major factors of personality with empirical paradigms from experimental, physiological, animal, clinical, educational, criminological or industrial psychology or to seek an explanation for the causes and major determinants of individual differences in concepts derived from these disciplines. The editors are concerned with both genetic and environmental causes, and they are particularly interested in possible interaction effects.
