There are positive and negative correlations in different directions between smoking, personality traits, and health-related quality of life (HRQOL), where smoking may mask the pathway between personality traits and HRQOL. Understanding the masking pathway of smoking between personality traits and HRQOL can elucidate the mechanisms of smoking's psychosocial effects and provide new ideas for developing tobacco control strategies.
The purpose of this study was to investigate the correlation between Big Five personality traits and HRQOL and whether smoking mediates the relationship between them.
This was a cross-sectional study using data from 21,916 respondents from the 2022 Psychology and Behavior Investigation of Chinese Residents survey. Linear regression models were used to analyze the correlations between smoking, Big Five personality traits, and HRQOL while controlling for potential confounders. The mediating role of smoking on the association between Big Five Personality traits and HRQOL was analyzed using the Sobel-Goodman mediation test.
Extraversion (β=.001; P=.04), agreeableness (β=.003; P<.001), and neuroticism (β=.003; P<.001) were positively correlated with HRQOL, whereas openness was negatively correlated with HRQOL (β=-.001; P=.003). Smoking was associated with a decrease in HRQOL and mediated the positive effect of HRQOL on extraversion (z=-2.482; P=.004), agreeableness (z=-2.264; P=.02), and neuroticism (z=-3.230; P=.001). Subgroup analyses further showed that smoking mediated the effect of neuroticism on HRQOL in the population with chronic illnesses (z=-2.724; P=.006), and in the population without chronic illnesses, smoking contributed to the effect of HRQOL on extraversion (z=-2.299; P=.02), agreeableness (z=-2.382; P=.02), and neuroticism (z=-2.213; P=.03).
This study provided evidence that there is a correlation between personality traits and HRQOL. It also found that smoking plays a role in mediating the connection between personality traits and HRQOL. The development of future tobacco control strategies should consider the unique traits of each individual's personality, highlighting the significance of extraversion, agreeableness, and neuroticism.
吸烟、人格特质和健康相关生活质量（HRQOL）之间存在正相关和负相关的关系，吸烟可能掩盖了人格特质和 HRQOL 之间的关系。了解吸烟对人格特质和 HRQOL 关系的掩盖途径，可以阐明吸烟的心理社会影响机制，并为制定烟草控制策略提供新的思路。
本研究旨在探讨大五人格特质与 HRQOL 的相关性，以及吸烟是否在其中起中介作用。
这是一项横断面研究，使用了 2022 年中国居民心理与行为调查中 21916 名受访者的数据。采用线性回归模型，在控制潜在混杂因素的情况下，分析吸烟、大五人格特质与 HRQOL 之间的相关性。采用 Sobel-Goodman 中介检验分析吸烟对大五人格特质与 HRQOL 之间关系的中介作用。
外向性（β=0.001；P=0.04）、宜人性（β=0.003；P<0.001）和神经质（β=0.003；P<0.001）与 HRQOL 呈正相关，而开放性与 HRQOL 呈负相关（β=-0.001；P=0.003）。吸烟与 HRQOL 下降有关，并中介了外向性（z=-2.482；P=0.004）、宜人性（z=-2.264；P=0.02）和神经质（z=-3.230；P<0.001）对 HRQOL 的正向影响。亚组分析进一步表明，在患有慢性病的人群中，吸烟中介了神经质对 HRQOL 的影响（z=-2.724；P=0.006），而在没有慢性病的人群中，吸烟促进了 HRQOL 对外向性（z=-2.299；P=0.02）、宜人性（z=-2.382；P=0.02）和神经质（z=-2.213；P=0.03）的影响。
本研究提供了人格特质与 HRQOL 之间存在相关性的证据，同时发现吸烟在人格特质与 HRQOL 之间的关系中起中介作用。未来的烟草控制策略的制定应考虑到每个人独特的人格特质，突出外向性、宜人性和神经质的重要性。
