VALIDATION OF THE BORDERLINE PERSONALITY FEATURES SCALE FOR CHILDREN ON STUDENTS IN SHIRAZ

The Borderline Personality Feature Scale for Children (BPFS-C) developed to assess borderline personality features in children aged 9 years and older. This scale was adopted from the borderline scale of PAI and assessed affective instability, identity problems, negative relationships, and self-harm dimensions. The aim of this study was to investigate the validity of this scale on non-clinical sample of students.

This study was conducted on 400 students (200 females, 200 males) with the mean age of 15.78 who were selected via multi-stage random sampling. All participants were asked to complete BPFS-C and Borderline Personality Scale (STB). The validity of BPFS-C was determined using confirmatory factor analysis, concurrent validity, and criterion validity, and its reliability was assessed by correlation coefficients, Kronbach’s alpha and split half method.

The correlation between borderline BPFS-C and STB was significant at p>0.001 (r|=0.51). Kronbach’s alpha for whole scale was 0.84 and for the subscales including affective instability, identity problems, negative relationships and self-harm was 0.78, 0.77, 0.77, and 0.76 respectively. Furthermore, the results obtained from confirmatory factor analysis (RMSEA=0.05) illustrate the fair fitness of four factor structure of BPFS-C.

The findings of the present study show that BPFS-C is reliable and valid in Iran.
