Why is authenticity associated with being and acting extraverted? Exploring the mediating role of positive affect

ABSTRACTExtraversion is linked to higher levels of authenticity. Why? Across four studies, we examined positive affect as a potential mediator. In Study 1 (N = 205), we tested our mediation model at the trait level. Then, focusing on the within-person state level: Study 2 (N = 97) involved a 10-week lab-based experience sampling protocol; Study 3 (N = 147) involved a preregistered week-long daily-life experience sampling protocol; and Study 4 (N = 129) involved a two-week naturalistic experience sampling protocol. In all four studies, positive affect explained moderate to high proportions of the effects of extraversion on authenticity (Study 1 = 29%, Study 2 = 38%, Study 3 = 87%, Study 4 = 86%). We discuss several theoretical interpretations.KEYWORDS: Extraversionpositive affectauthenticitywellbeingpersonality states AcknowledgmentsData collection for Study 2 was supported by the National Institute of Mental Health of the National Institutes of Health under award number R01MH70571.

We did not assess authenticity as conceptualized in trait authenticity models, which include a general authenticity domain as well as facet-level constructs (e.g., Kernis & Goldman, Citation2005; Wood et al., Citation2008). We believe that our measures are likely highly related to the constructs assessed by such models because our items contain similar content at face value. For example, our items and measures of the models referenced above assess perceptions of behaving in line with one’s true nature and perceptions of acting phony or putting on an act.2. It is also important to note that socializing may also be an outcome of state extraversion and state PA, and thus controlling for socializing may introduce collider bias that would artificially inflate the estimated effects. Therefore, we conducted follow-up models not controlling for time spent socializing. Results did not change (see the Supplemental Materials).Additional informationFundingThis research was supported by a Melbourne Research Grant Support Scheme awarded to the last author.
