Objective: The purpose of this study is to conduct validity and reliability studies of the Inventory of Psychological Disorders for Adolescents-Psychological Disorders Form (PDIA-PDF), which were created by using the original Inventory of Psychological Disorders for Adolescents (PDIA). Methods: The study consisted of a sample group of 812 high school and university students, including 527 female (64.9%) and 285 male (35.1%) aged 15-22 (18.43±1.60) years.Test-retest reliability was also examined in 52 participants. Furthermore, in the context of convergent validity, it were applied EPBE-PBF to a sample group of 127 persons in the first session. It were applied together State Trait Anxiety Inventory (STAI), Brief Symptom Inventory (BSI) and Beck Depression Inventory (BDI) in second session. Results: In the reliability study, the Cronbachs alpha for the total scale was 0.78 and for sub-scales, it was between 0.57 and 0.89. It was also found that item-total correlations for each subscale were higher than 0.30. Correlation coefficient values for test-retest reliability were between 0.53 and 0.90. The Pearsons corre-lation values varied between 0.37 and 0.79. As PDIA-PDF is an inventory with profile index such as MMPI, each subscale was subjected to confirmatory factor analysis in accordance with Varimax rotation in itself. Discussion: It is seen that PDIA-PDF is a valid and reliable scale according to the validity reliability analyzes performed secondly after the original study.
