Early intervention for adolescents with borderline personality disorder: quasi-experimental comparison with treatment as usual.

Objective: The aim of the present study was to compare the effectiveness of specialized team-based early intervention for borderline personality disorder (BPD) with treatment as usual.

Method: In a quasi-experimental design, 32 outpatients who received historical treatment as usual (H-TAU) were compared with 78 participants from a recently published randomized controlled trial of cognitive analytic therapy (CAT; n = 41) versus manualized good clinical care (GCC; n = 37), conducted in a specialized early intervention service for BPD (the Helping Young People Early (HYPE) programme). All participants were 15-18-year-old outpatients who fulfilled 2-9 DSM-IV BPD criteria.

Early intervention for adolescents with borderline personality disorder using cognitive analytic therapy: randomised controlled trial.

Background: No accepted intervention exists for borderline personality disorder presenting in adolescence.

Aims: To compare the effectiveness of up to 24 sessions of cognitive analytic therapy (CAT) or manualised good clinical care (GCC) in addition to a comprehensive service model of care.

Method: In a randomised controlled trial, CAT and GCC were compared in out-patients aged 15-18 years who fulfilled two to nine of the DSM-IV criteria for borderline personality disorder.

Two-year stability of personality disorder in older adolescent outpatients.

The 2-year stability of categorical and dimensional personality disorder (PD) in an older adolescent psychiatric outpatient sample was examined. One hundred and one 15-18-year-old participants were assessed using the Structured Clinical Interview for DSM Axis II Disorders (SCID-II) at baseline and 97 were re-interviewed, face-to-face, at 2 years. Of those with a categorical PD diagnosis at baseline, 74% still met criteria for a PD at follow-up, with marked gender differences (83% of females and 56% of males).
