“…Indeed, there is some evidence that personality can change as a function of experience (Jackson, Thoemmes, Jonkmann, Ludtke & Trautwein, 2012;Roberts & Jackson, 2008;Tang et al, 2009). Therefore, in order to fully elucidate how personality and stress processes interact over time, researchers ought to adopt life course approaches that assess multiple predictors and multiple outcomes across a large number of years (for more detail see Segerstrom & O"Connor, 2012;also Hagger-Johnson et al, 2012) or econometric approaches (Ferguson, 2013b;Ferguson, Heckman & Corr, 2011). The importance of adopting such approaches is underscored by the recent publication of the landmark study by Jokela et al (2013b) that demonstrated that C was the only higher-order personality trait to be related to mortality risk across a staggering 7 different cohort studies.…”
