Different studies shows that personality has impacts on life satisfaction (Yap, Anusic, & Lucas, 2012; Anusic, Soto & Luhmann, 2013; Yap, & Lucas, 2014; Boyce, Wood & Ferguson, 2016). For instance married people have higher average levels of life satisfaction more than non-married ones (Boyce, Wood & Ferguson, 2016). Personality represents basic individual tendencies and it comprises agreeableness, conscientiousness, extraversion, neuroticism, and openness to experience. Individuals can conclude and express accurately what these basic tendencies are from their own behaviours and experiences.
Personality predict the increases and the decreases in life satisfaction as it has been revealed by Anusic, Yap & Lucas (2014). In their study carried out in Australia that was aimed to evaluate how life satisfaction changed following major life events and the extent to which personality moderated those change. By using the data from HLDA (Household, Income and Labour Dynamics in Australia Survey. This study replicated the one carried out by Yap, Anusic & Lucas (2012) in British Household Panel Survey (BHPS). Both studies used samples from marriage, childbirth, widowhood and unemployment. This study found that that marriage, childbirth, widowhood, and unemployment are associated with significant changes in life satisfaction in the time around the event. Those results also replicate the finding that married people remain higher in life satisfaction than those who remain unmarried and this effect persists even after accounting for pre-existing differences between married and unmarried people. Those who have children or become unemployed, on the other hand, do not display lasting changes in life satisfaction after normative changes are taken into account.
Certainly, the results from those both studies (the one of HILDA conducted by Anusic, Yap & Lucas (2014), and the other one of BHPS by conducted by Yap, Anusic & Lucas (2012), suggest that in the long run married people are better off than if they had remained unmarried, but that childbirth and unemployment are not associated with lasting changes in life satisfaction that are unique to the experience of these events. Concerning the moderating effects of personality, the results of this study again replicate the findings of Yap et al. (2012) and suggest that the Big Five are not consistently associated with variation in the degree to which well-being changes following major life events. Also both studies found that people higher in agreeableness report more declines in life satisfaction following marriage.
Personality has an influence on marriage life satisfaction. For instance Boyce, Wood & Ferguson (2016) conducted a study that was aimed to show the moderating effects of personality on marriage life satisfaction. Using a sample of 2015 participants (1547 single adults and 468 married), this study examined whether following marriage pre-marital personality predicts different changes to life satisfaction. The findings from this study revealed that conscientious women experience greater life satisfaction following marriage than less conscientious women. Also this study revealed that introverted women and extraverted men experience longer-term life satisfaction benefits following marriage.
The big five personality traits impacts the income on life satisfaction, as it has been concluded by Soto & Luhmann (2013), in their research that was aimed to test if the big five personality traits moderate the effects of income on life satisfaction. By analysing the data from three large-sample, nationally representative, longitudinal studies: the British Household Panel Survey, the German Socio-Economic Panel Study, and the Household Income and Labour Dynamics in Australia Survey. The results from their analysis shown that Neuroticism consistently moderated the effects of both stable between-person income differences and within-person income fluctuations on life satisfaction. Exactly, income predicted satisfaction more strongly for highly neurotic individuals than for their emotionally stable peers. These findings also illustrate that the effects of life circumstances on subjective well-being can vary considerably across individuals, depending on their basic personality traits.
