The high correlation coefficient (r = .87) indicates that there is high intercoder reliability for this judgment task, meaning that the judges are consistent in their ratings of how often self-words are mentioned in the diaries. This suggests that the methodology can be used reliably in future research. However, the correlation does not provide information on the validity of the diary-writing task as a measure of personality.
