title: Personality and having children: a two-way relationship.
abstract: Personality has been implicated in romantic and sexual relationships, but its association with childbearing is poorly understood. The authors assessed whether 3 personality traits--sociability, emotionality, and activity--predicted the probability of having children and whether having children predicted personality change. The participants were women and men from the Cardiovascular Risk in Young Finns study (N = 1,839) who were followed for 9 years. High emotionality decreased the probability of having children, whereas high sociability and, in men, high activity increased this probability. Having children predicted increasing emotionality, particularly in participants with high baseline emotionality and two or more children. In men, having children increased sociability in those with high baseline sociability and decreased sociability in those with low baseline sociability. These findings suggest a two-way relationship between personality and having children.
