A convergent validity correlation between self-reports and observer reports of about .50 or .60 is a typical correlation for a well-constructed, full-length personality inventory scale. This indicates that the self-reported scores and observer-reported scores are moderately to strongly positively correlated, suggesting that the measures are tapping into the same underlying construct or traits. Correlations of .05 or .15 (choice A) would be considered low, while correlations of .20 or .30 (choice B) would be considered moderate but still lower than what is typically seen in a well-constructed personality inventory. Correlations of .75 or .85 (choice D) or above .90 (choice E) would be considered high and may suggest that there is some overlap between the measures but also some unique information being captured by each source. However, these high correlations may also indicate that there is some response bias or social desirability influencing both self-reports and observer reports.
