= p≤ .08. Kendall’s tau was inverse logit transformed before calculating the reported correlations. The mean and standard deviation of Kendall’s tau in the table reflects the logit transformed variable; as reported in the text, the mean and standard deviation of the non-transformed variable was 0.81 (SD=.11), with a range from 0.47–0.99. PCL-R=Psychopathy Checklist Revised; BIDR IM = Balanced Inventory of Desired Responding Impression Management; STAI=Spielberger State Trait Anxiety Scale.
