Abstract
Reports an error in "Costs and benefits of acting extraverted: A randomized controlled trial" by Rowan Jacques-Hamilton, Jessie Sun and Luke D. Smillie (Journal of Experimental Psychology: General, 2019[Sep], Vol 148[9], 1538-1556; see record 2018-58861-001). In the article (https://doi.org/10.1037/xge0000516), it was originally reported that momentary authenticity was measured with three items (found in the ESM questionnaire section). However, one of these items was omitted, and only the remaining two were used for the statistical analyses. The omitted item was "In the past hour, how much were you putting on an act?" Furthermore, the within-person omega reliability value for momentary authenticity reported in Table 1 is incorrect. The correct value is 0.62. (The following abstract of the original article appeared in record 2018-58861-001.) Evidence suggests that extraverted (i.e., bold, agentic) behavior increases positive affect (PA), and could be targeted in wellbeing interventions. However, this evidence is either causally ambiguous or has questionable ecological validity, and the potential costs of sustained extraverted behavior have received minimal attention. To address these limitations, we conducted a randomized controlled trial examining the wellbeing benefits and costs of an extraverted behavior intervention conducted in everyday life. Participants (n = 147) were randomly assigned to an "act-extraverted" intervention or a "sham" (active control) intervention for 1 week in everyday life. Additional data for a contact control condition were obtained from a previous study (n = 76). Wellbeing outcomes included PA and negative affect (NA), feelings of authenticity, and tiredness-assessed both in the moment and retrospectively. There was a positive overall effect of the acting extraverted intervention on PA and authenticity. However, wellbeing outcomes also depended on dispositional extraversion: more introverted participants had weaker PA increases, experienced increased NA and tiredness, and decreased feelings of authenticity. Implications for wellbeing interventions and personality theory are discussed. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
