SI-Bord consists of 5 questions representing the DSM-5 criteria of BPD for 1) abandonment avoidance, 2) interpersonal relationships instability, 3) identity disturbance, 4) suicidal and self-harm behaviors and 5) affective instability. It is a 4-point Likert scales, ranging from never (0) to very often (3). The total score ranges from 0 to 15. The higher score represents more BPD symptoms or traits.
- SI-Bord showed to be a unidimensional scale with acceptable reliability (Cronbach’s alpha is 0.76) among Thai university students, and Cronbach's alpha of 0.724 among 700 Chinese university students.
SI-Bord positively correlated with depression and perceived stress (r = 0.669 to r = 0.690, p < 0.001) but negatively correlated with perceived social support (r = -0.520, p < 0.001).
The ROC curve was analyzed against gold standard (the psychiatrists). The AUC was 0.826 (95% CI, 0.715–0.907; p < 0.0001). Youden’s index and optimal criterion suggested a cut-off of > 9, which yielded a sensitivity of 56.25% (95%CI, 29.9%–80.2%), a specificity of 92.31% (95%CI, 81.5%–97.9%). With the cut-off >7, it yielded a sensitivity of 75.00% (95%CI,47.6 - 92.7), and a specificity of 73.08% (95%CI,59.0 - 84.4).
