“…In addition, the mean levels of repeated measures should also correlate with independent trait measures of extraversion to further validate the consistency criterion. Findings from repeated measurements of the extraverted behavior of multiple individuals demonstrate that there are indeed robust individual differences in mean levels of extraverted behaviors, but these also tend to be less consistent than behaviors that are relevant for other "Big Five" traits (Catterson, Eldesouky, & John, 2017;Heller, Komar, & Lee, 2007;Leikas & Ilmarinen, 2017;Sun, Stevenson, Kabbani, Richardson, & Smillie, 2017;Wilt, Bleidorn, & Revelle, 2017). Moreover, support for a correlation between individual mean levels of behaviors and independent trait measures is mixed (Heller et al, 2007;Leikas & Ilmarinen, 2017), perhaps owing to the smaller sample sizes that are typical in experience sampling research.…”
