Abstract
Objective: This study aims to conduct validity and reliability studies of the Inventory of Psychological Disorders for Adolescents-Personality Disorders Form (PDIA-PDF), which were created by using the original Inventory of Psychological Disorders For Adolescents (PDIA). Method: The study consisted of a sample group of 827 high school and university students, including 539 female (71.7%) and 234 male (28.3%) aged 13-24 (19.17±2.66) years. Test-retest reliability was also examined in 41 participants. In the context of convergent validity, it were applied together EPBE-PBF to a sample group of 78 persons Minnesota Multiphasic Personality InventoryPersonality Disorders (MMPI-PD), to a sample group of 103 Personality Belief Questionnaire-Turkish Short Form (PBQ-TSF) and to a sample group of 44 The Structured Clinical Interview for DSM-III Axis II Disorders (SCID-II). Results: In the reliability study, the Cronbach’s alpha for the total scale was 0.77 and for subscales, it was between 0.70 and 0.87. 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 0.65 and 0.92. In the convergent validity analyzes, thePearson’s correlation values varied between 0.17 and 0.78. Discussion: It is seen that PDIA-PDF is a valid and reliable scale according to the validity reliability analyzes performed thirdly after the original study and first revision study. In addition, the prevalance of personality disorders in our study ranged from 2.54% to 5.56% and these findings are similar to those in the literature.
