The Validity and Reliability of Borderline Personality Features Scale for Children-Short Form in Turkish Adolescents

Abstract

Objective: This study has aimed to investigate the validity and reliability of the Borderline Personality Features Scale for Children-Short Form (BPFSC-SF-TR) in Turkish adolescents. Method: The study was carried out with adolescents between the ages of 12-18 from clinical (N=168) and community (N=181) backgrounds. All participants were asked to complete the BPFSGSF-TR, the Personality Belief Questionaire - Short Form (PBQ-SF), the Brief Symptom Inventory (BSI) and the Personality Inventory for DSM-5Short Form (PID-5-SF) scales. Also, the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-Turkish Version (K-SADS-PL-TR) was administered to the participants in the clinical group and their parents were asked to complete the Pediatric Quality of Life Inventory (PEDsQL). Test-retest correlations and the Cronbach's a coefficients were calculated. Results: BPFSGSF-TR scores of both groups of participants positively correlated with the PBQ-BF borderline subscale, the PID-5-SF borderline related facets and the BSI scores, and negatively correlated with the PedsQL in the clinical group. Furthermore, the clinical group had higher total BPFSGSF-TR scores than the community group, and their scores positively correlated with the number of diagnoses and psychiatric symptoms determined by using the KSADS-PL-TR. Exploratory and multi-group confirmatory factor analyses of the data of both groups supported a single factor structure. The Cronbach's a of the scale was 0.84 in the clinical group, and 0.79 in the community group. The test-retest reliability correlation coefficient of the scale was 0.71. Conclusion: The BPFSGSF-TR is a valid and reliable tool for Turkish adolescents.
