The Scale of Accurate Personality Prediction (SAPP) is a measure to determine the accuracy of an individual’s ability to predict his/her own personality traits. Previous studies have demonstrated the validity of SAPP as a measure, and this study serves as one in a series of study on the reliability of the SAPP. To establish the test-retest reliability of the SAPP, the SAPP scores of 22 participants were calculated from two testing trials separated by a six week interval. A Pearson correlation indicated a significant correlation of moderate strength between the SAPP scores from the two testing trials (r² =.572, p<0.01). The implication of these results within the context of the previous test-retest reliability studies and limitations to the current study are discussed.
