Test-retest reliability was also examined in 64 participants and correlation coefficient values for test-retest reliability were between 54-.86. Furthermore, convergent validity was tested with 5 different scales and PDIA in pairs or triple sets using 674 individuals from sample. The Pearson correlation values varied between .27 and 75. As PDIA is an inventory with profile index such as MMPI, each subscale was subjected to confirmatory factor analysis in accordance with Varimax rotation in itself.
