Baby bliss: Longitudinal evidence for set-point theory around childbirth for cognitive and affective well-being

Becoming a parent relates not only to joy but also to new challenges. Consistent with set-point theory, previous research found that life satisfaction increased around childbirth but decreased back to baseline in the following years. However, it remains unresolved whether individual facets of affective well-being show lasting or temporary changes around childbirth.

In 5,532 first-time parents from the German Socio-Economic Panel (SOEP), we tested how life satisfaction, happiness, sadness, anxiety, and anger changed in the five years before and five years after becoming a parent.

Parents experienced a large increase in life satisfaction and happiness in the years surrounding the birth of their first child. This increase was most pronounced in the first year of parenthood. Sadness and anger decreased in the years before childbirth, reached their lowest point in the first year of parenthood, and increased in the following years. Anxiety slightly increased in the five years before childbirth but was lower thereafter. Most well-being changes bounced back in the long run, resulting in comparable well-being levels five years after versus five years before becoming a parent.

These findings suggest that set-point theory also applies to different facets of affective well-being across the transition to parenthood. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
