Love, work, and changes in extraversion and neuroticism over time.

Area of Science:

• Psychology
• Developmental Psychology
• Personality Psychology

Background:

• Personality traits exhibit individual differences in their trajectories over time.
• Life satisfaction, encompassing work and relationships, is a key indicator of well-being.
• Understanding the interplay between personality change and life satisfaction is crucial for developmental research.

Purpose of the Study:

• To investigate individual differences in the changes of extraversion and neuroticism.
• To examine the correlations between changes in personality traits and changes in work and relationship satisfaction.
• To determine the directionality of influence between personality traits and role satisfaction.

Main Methods:

• Longitudinal data from the Victorian Quality of Life Panel Study (1981-1989).
• Involved 1,130 participants aged 16-70, assessed every two years.
• Utilized cross-lagged models to analyze trait-role satisfaction dynamics.

Main Results:

• Significant individual variations in changes in extraversion and neuroticism were observed.
• Personality development and changes in satisfaction occurred across adulthood, not solely in young adulthood.
• Increased work and relationship satisfaction correlated with decreased neuroticism and increased extraversion (average relation magnitude of .40).
• Cross-lagged models suggested personality traits predominantly influence role satisfaction, with some evidence for work satisfaction enhancing extraversion.

Conclusions:

• Personality traits and life satisfaction are dynamically related throughout adulthood.
• Systematic developmental changes link personality shifts with evolving satisfaction levels.
• The findings highlight the interconnectedness of personality and well-being, with implications for understanding adult development.
