Extraversion, situation characteristics and everyday happiness

This study examined the effect of extraversion and DIAMONDS situation characteristics, including Duty, Intellect, Adversity, Mating, Positivity, Negativity, Deception, and Sociality, on state happiness among Chinese participants. With a daily diary design, Study 1 established the relation between extraversion and daily happiness. With an experience sampling design, Study 2 not only replicated the positive relation between extraversion and state happiness, but also extend this conclusion by examining the effects of DIAMONDS situation characteristics on momentary happiness. Specifically, mating, positivity and sociality positively predicted momentary happiness, whereas adversity, negativity and deception negatively predicted momentary happiness. Duty and intellect were not related to momentary happiness. Interactions between extraversion and situation characteristics were also examined. Implications and limitations of this research are discussed.
