Some people use health care services more than others. Identifying factors associated with health care use has the potential to improve the effectiveness, efficiency, and equity of health care. In line with the Andersen behavioral model of health care utilization and initial empirical findings, personality traits may be key predisposing factors associated with health care use. Across 15 samples, the present study examined cross-sectional and prospective associations between Big Five personality traits and the likelihood of dental visits, general medical practitioner visits, and hospitalizations. Using coordinated data analysis, we estimated models within each of 15 samples individually (sample Ns ranged from 516 to 305,762), and then calculated weighted mean effect sizes using random-effects meta-analysis across samples (total N = 358,803). According to the synthesized results, people higher in conscientiousness, agreeableness, extraversion, and openness, and lower in neuroticism were more likely to visit the dentist; people higher in neuroticism were more likely to visit general medical practitioners; and people lower in conscientiousness and agreeableness and higher in neuroticism were more likely to be hospitalized. Associations tended to be small with odds ratios around 1.20 (rs ≈ .05). These findings provide evidence across 15 international samples for small but consistent associations between personality traits and health care use and demonstrate that personality-health care associations differ by type of care. We discuss directions for future research, including examining more specific personality facets (e.g., productiveness vs. responsibility) as well as important dimensions of health care (e.g., preventative vs. reactive care; acute vs. chronic care).

人格特质和医疗保健使用：对 15 个国际样本的协调分析。


有些人比其他人更多地使用医疗保健服务。识别与医疗保健使用相关的因素有可能提高医疗保健的有效性、效率和公平性。根据医疗保健利用的安徒生行为模型和初步实证研究结果，人格特质可能是与医疗保健利用相关的关键诱发因素。本研究通过 15 个样本检验了大五人格特征与看牙医、全科医生就诊和住院的可能性之间的横向和前瞻性关联。使用协调数据分析，我们分别估计了 15 个样本中的每个样本（样本 N 范围从 516 到 305,762），然后使用跨样本的随机效应荟萃分析计算加权平均效应大小（总 N = 358,803）。根据综合结果，责任心、宜人性、外向性和开放性较高、神经质较低的人去看牙医的可能性更大；神经质程度较高的人更有可能去看全科医生；责任心和随和性较低、神经质较高的人更有可能住院。相关性往往较小，优势比约为 1.20 (rs ≈ .05)。这些研究结果为 15 个国际样本提供了证据，证明人格特质与医疗保健使用之间存在微小但一致的关联，并证明人格与医疗保健的关联因护理类型而异。我们讨论了未来研究的方向，包括检查更具体的人格方面（例如，生产力与责任）以及医疗保健的重要方面（例如，预防性护理与反应性护理；急性护理与慢性护理）。 （PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
