Four main findings suggest that the AC method is useful for assessing personality traits. First, across two samples, results provide evidence for the construct-related validity of personality-based AC dimension ratings. This is a noteworthy finding because evidence supporting the internal construct-related validity of conventional (i.e., non-Big Five) AC dimensions has typically been lacking (e.g., Lance et al., 2004; Woehr & Arthur, 2003). Previous research sought to address this issue by improving assessor training and rating approaches (see Lievens, 1998). Although this had some success, our findings indicate that making changes in terms of what to assess (changing the dimensions assessed in ACs) might yield larger benefits than adjusting how to assess them. Second, our findings indicate that assessing the Big Five traits as AC dimensions does not impair the criterion-related validity of AC ratings. Ratings of the Big Five as AC dimensions were as criterion-valid as ratings of conventional AC dimensions typically examined in prior AC research. Specifically, correlations between AC ratings and job performance in the present study (i.e., a mean correlation of .17 across all Big Five traits and a correlation of .22 when using the overall AC score) were comparable to uncorrected meta-analytic correlations of conventional AC ratings and job performance (i.e., .17 and .23 in Hermelin et al., 2007; Sackett et al., 2017).
