UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.
■本研究的目的是调查大五人格特质与HRQOL之间的相关性,以及吸烟是否介导了两者之间的关系。
■这是一项横断面研究,使用了来自2022年中国居民心理和行为调查的21,916名受访者的数据。线性回归模型用于分析吸烟,五大人格特质,和HRQOL,同时控制潜在的混杂因素。使用Sobel-Goodman调解测验分析了吸烟在大五人格特征与HRQOL之间的中介作用。
■外向性(β=.001;P=.04),一致性(β=.003;P<.001),神经质(β=.003;P<.001)与HRQOL呈正相关,而开放性与HRQOL呈负相关(β=-.001;P=.003)。吸烟与HRQOL下降相关,并介导HRQOL对外向性的积极影响(z=-2.482;P=.004),同意(z=-2.264;P=0.02),和神经质(z=-3.230;P=.001)。亚组分析进一步表明,吸烟介导了慢性疾病人群中神经质对HRQOL的影响(z=-2.724;P=.006),在没有慢性病的人群中,吸烟有助于HRQOL对外向性的影响(z=-2.299;P=0.02),同意(z=-2.382;P=.02),和神经质(z=-2.213;P=0.03)。
■这项研究提供了证据,表明人格特质与HRQOL之间存在相关性。研究还发现,吸烟在人格特质与HRQOL之间的关系中起着中介作用。未来控烟策略的制定应考虑每个个体的独特个性,强调外向的重要性,令人愉快,和神经质。
