There is some evidence that personality relates to childbearing in adulthood but the importance of personality for reproductive capacity is unknown. This study explored cross-time associations between the major dimensions of trait personality and self-reported fertility and fecundity.
A representative sample of young Australian adults [n = 4501; age range ≈ 18-44 (women), 18-54 (men)] provided information on personality, fertility, fertility intentions, fecundity and lifestyle factors (cigarette smoking, alcohol consumption, physical activity) in 2006 and again in 2016. Older Australian adults [n = 4359; age ≥ 45 (women), ≥ 55 (men)] provided information on personality, lifestyle factors and completed fertility.
After controlling for sociodemographic factors, completed fertility was associated with higher agreeableness in both sexes, and lower conscientiousness and openness in women. In younger adults, higher levels of openness were associated with fewer children 10 years later in both sexes, and higher extraversion was associated with more children 10 years later in men. The association between fertility intentions and subsequent fertility was stronger among women scoring higher on conscientiousness, and women scoring higher on neuroticism were more likely to acquire medical or health difficulties in having children - an effect that was mediated by higher levels of cigarette smoking.
The study provides initial evidence for an association between personality and the acquisition of difficulties in having children.
有一些证据表明，人格与成年后的生育有关，但人格对生育能力的重要性尚不清楚。本研究探讨了特质人格的主要维度与自我报告的生育能力和生育力之间的跨时间关联。
澳大利亚年轻成年人的代表性样本[n=4501；年龄范围约为 18-44 岁（女性），18-54 岁（男性）]于 2006 年和 2016 年提供了关于人格、生育能力、生育意愿、生育力和生活方式因素（吸烟、饮酒、身体活动）的信息。年长的澳大利亚成年人[n=4359；年龄≥45 岁（女性），≥55 岁（男性）]提供了关于人格、生活方式因素和生育情况的信息。
在控制了社会人口因素后，无论在男性还是女性中，较高的宜人性与较高的生育能力相关，而较低的尽责性和开放性与较低的生育能力相关。在年轻成年人中，较高的开放性与两性 10 年后生育的孩子数量较少相关，而较高的外向性与男性 10 年后生育的孩子数量较多相关。在责任心得分较高的女性中，生育意愿与随后的生育之间的关联更强，而神经质得分较高的女性在生育过程中更有可能出现医疗或健康问题——这种效应是由吸烟水平升高介导的。
该研究首次提供了人格与生育困难获得之间存在关联的证据。
