Does personality moderate reaction and adaptation to major life events? Analysis of life satisfaction and affect in an Australian national sample.

We used a nationally representative panel of Australian households to replicate a study by Yap et al. (2012) that evaluated how life satisfaction changed following major life events and the extent to which personality moderated those changes. We replicated the protective function of marriage but found that long-term declines that follow widowhood mostly reflect normative changes. In addition, we found that people reported slight decreases in positive affect following marriage and childbirth, an increase in positive affect following widowhood, and a slight increase in negative affect following childbirth, relative to normative trajectories. The Big Five did not moderate response to life events in a way that is consistent with past theory and research.
