The personality trait of negative affectivity (NA) is associated with reports of worse physical health, more symptoms and worse health-related quality of life but its associations with oral quality of life (OQOL) are unexplored. In this study we examined the association of NA with OQOL.
We drew on data from two samples of older men: The VA Dental Longitudinal Study (DLS; n=177) and the Veterans Health Study (VHS; n=514), which included three measures of oral quality of life: the Oral Health-Related Quality of Life Measure (OHQOL), the Oral Health Impact Profile (OHIP), and the Geriatric Oral Health Assessment Instrument (GOHAI). For each OQOL measure, and the GOHAI and OHIP subscales, two regression models were estimated to examine the marginal change in variance due to NA: the first model included age, number of teeth, and self-rated oral health, and the second added NA.
In both bivariate and multivariate analyses, higher NA was consistently associated with worse scores on the OQOL measures. In the regression analyses, NA explained an additional.01 to 18% of the variance in OQOL, explaining the most variance in the OHIP and the least in the OHQOL. The addition of NA explained more variance in the more subjective, psychologically oriented GOHAI and OHIP subscales than it did in the more objective, physical function oriented subscales.
Psychosocial factors such as personality are significantly associated with quality of life ratings. Such associations should be taken into account when OQOL measurements are used and interpreted.
消极情感性（NA）人格特质与较差的身体健康报告、更多症状及较差的健康相关生活质量相关，但它与口腔生活质量（OQOL）的关联尚未得到探讨。在本研究中，我们考察了NA与OQOL的关联。
我们利用了来自两个老年男性样本的数据：退伍军人事务部牙科纵向研究（DLS；n = 177）和退伍军人健康研究（VHS；n = 514），其中包括三项口腔生活质量测量指标：口腔健康相关生活质量测量量表（OHQOL）、口腔健康影响程度量表（OHIP）和老年口腔健康评估工具（GOHAI）。对于每项OQOL测量指标以及GOHAI和OHIP分量表，估计了两个回归模型以考察因NA导致的方差边际变化：第一个模型纳入了年龄、牙齿数量和自评口腔健康状况，第二个模型加入了NA。
在双变量和多变量分析中，较高的NA始终与OQOL测量指标得分较差相关。在回归分析中，NA解释了OQOL中额外0.01%至18%的方差，在OHIP中解释的方差最多，在OHQOL中解释的方差最少。与更客观、以身体功能为导向的分量表相比，NA的加入在更主观、以心理为导向的GOHAI和OHIP分量表中解释了更多的方差。
人格等社会心理因素与生活质量评分显著相关。在使用和解释OQOL测量结果时应考虑到此类关联。
