PREDICTION OF TREATMENT OUTCOME OF ADOLESCENTS WITH BORDERLINE PERSONALITY DISORDER: A 2-YEAR FOLLOW-UP STUDY

This study examined prediction of various clinical outcomes in adolescents with borderline personality disorder (BPD) features. Of the 112 adolescents who participated at baseline, 97 were seen at 2-year follow-up, of which 49 (50.5%) had clinically improved, defined as a decrease in BPD pathology of minimum 12 points on the Borderline Personality Features Scale for Children (BPFS-C). Eighty-one adolescents fulfilled the diagnostic criteria for BPD and scored above clinical cutoff on the BPFS-C at baseline, of which 26 (32%) had remitted at follow-up by self-report on the BPFS-C. Results showed that adolescents with comorbid oppositional defiant disorder at baseline were less likely to have clinically improved or remitted at follow-up. Participants with increased self-reported depression and less exposure to physical abuse at baseline had increased odds of remission. Our findings suggest that more internalizing and less externalizing symptoms increase the odds of positive treatment outcome in adolescents with BPD.
