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 nonclinical
sample
of
students.

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