<P> In multiple studies, neuroticism has been shown to have an equal, if not larger, impact on happiness and subjective well - being than extraversion . One study classified school children into four categories based on their scores in assessments of extraversion and emotional stability (neuroticism). The results showed no significant difference between the happiness levels of stable introverts and stable extraverts, while unstable extraverts and introverts both demonstrated significantly less happiness than their counterparts . In this study, neuroticism appeared to be the more salient factor for overall well - being . </P> <P> Likewise, in later studies, researchers used assessment scales to test for categories such as self - esteem and life - goal orientation, which they had positively correlated with happiness . Participants' responses to these scales suggested that neuroticism actually had a larger impact than extraversion in measures of well - being . </P> <P> Though extraversion and neuroticism seem to have the largest effect on personal happiness, other Big 5 personality factors have also been shown to correlate with happiness and subjective well - being . For example, one study showed that conscientiousness and agreeableness correlated about 0.20 with subjective well - being . While the effect of these traits was not as strong as extraversion or neuroticism, it is clear that they still have some impact on happiness outcomes . </P> <P> Similarly, interactions between extraversion, neuroticism, and conscientiousness have demonstrated significant impacts on subjective - well being . In one study, researchers used three scale to assess subjective well - being . They found that extraversion only served as a predictor for one assessment, in conjunction with neuroticism, while the other two assessment outcomes were better predicted by conscientiousness and neuroticism . In addition to the importance of including other factors in happiness assessments, this study also demonstrates the manner in which an operational definition of well - being changes whether extraversion emerges as a salient predictive factor . </P>
