Objective: This study aimed to establish the validity and reliability of
the Turkish version of the DSM-5 Personality Inventory (PID-5) and
to evaluate it by comparing it with categorical personality assessments
obtained through the Structured Clinical Interview for DSM-III-R Axis
II Personality Disorders Questionnaire (SCID-II-PQ).
Methods: The sample consisted of 1736 participants, including 560
psychiatric patients diagnosed through clinical evaluation according to
DSM-5 diagnostic criteria in a psychiatry outpatient clinic and 1176
healthy controls. In addition to the PID-5, a sociodemographic data
form and the SCID-II-PQ were administered. Reliability was assessed
using Cronbach’s alpha coefficients for both domains and facets.
Given the inventory’s predefined domains and facets, confirmatory
factor analysis (CFA) was conducted to examine structural validity.
Convergent validity was tested through correlations between PID-5
domain and facet scores and both the dimensional scores and self-report
questionnaire scores of the SCID-II-PQ.
Results: The overall Cronbach’s alpha coefficient for the inventory
was 0.932, indicating high internal consistency. Confirmatory factor
analysis indicated that the findings of the present study demonstrated
a structure consistent with the personality domains identified in the
original PID-5 study. At the facet level, higher RMSEA values were
observed for the facets of ‘emotional lability’ and ‘manipulativeness’ ,
whereas the ‘risk-taking’ facet showed lower fit indices compared to the
other facets. In terms of discriminant validity, all domains and all facets
except ‘manipulativeness’ yielded higher mean scores among the patient
group compared to healthy controls.
Conclusions: The findings of this study indicate that the Turkish
version of the PID-5 demonstrates generally acceptable levels of validity
and reliability and may be used as an assessment tool for the dimensional
evaluation of personality traits.
