The effects of a personality intervention on satisfaction in 10 domains of life: Evidence for increases and correlated change with personality traits.

Abstract

The desire to change one's personality traits has been shown to be stronger if people are dissatisfied with associated aspects of their life. While evidence for the effects of interventions on personality trait change is increasing, it is unclear whether these lead to subsequent improvements in the satisfaction with various domains of life. In this study, we examined the effects of a 3-month digital-coaching personality change intervention study on 10 domains of satisfaction. We focused on the three largest intervention groups of the study (N = 418), which included participants who wanted to increase their Emotional Stability, Conscientiousness, or Extraversion. Bivariate latent change score models were used to examine correlated change between the targeted personality traits and satisfaction domains. We found that global life satisfaction and satisfaction with oneself as a person increased in all three intervention groups. In addition, increases in specific satisfaction domains were reported for the Conscientiousness (e.g., work/school, health, friendships) and Emotional Stability (e.g., family, sexual relationships, emotions) group. Increases were stable up to the 3-month follow-up. In contrast, the waitlist control group did not report any changes in global or domain-specific life satisfaction. Changes in the satisfaction domains were positively correlated with self-reported personality trait change to a similar degree as the cross-sectional associations, but not to observer-reported personality trait change. The personality intervention thus seemed to have a positive effect on satisfaction with various domains of life, which was associated with the degree of self-reported personality trait change.
