IES-27 Impulsivity and Emotion Dysregulation Scale, BSL-23 Borderline Symptom List, CFI comparative fit index, RMSEA root-mean-square error of approximation, df degrees of freedom, ΔCFI ≥ 0.010 and ΔRMSEA ≥ -0.0015 indicate substantial deterioration in model fit. Models are compared with the prior model consisting of one less level of constraint
