Combined therapy with interpersonal psychotherapy adapted for borderline personality disorder: A two-years follow-up.

Few investigations evaluated the long-term effects of psychotherapies in borderline personality disorder (BPD). In a previous study, we compared efficacy of combination of fluoxetine and interpersonal psychotherapy adapted to BPD (IPT-BPD) versus single fluoxetine administered for 32 weeks. This study is aimed to investigate whether the results obtained with the addition of IPT-BPD persist during a follow-up period. Forty-four patients who completed the 32 weeks trial underwent 24 months of follow-up receiving fluoxetine 20-40 mg/day. Clinical Global Impression Severity (CGI-S), Hamilton Rating Scales for Depression and Anxiety (HDRS, HARS), Social and Occupational Functioning Assessment Scale (SOFAS), Satisfaction Profile (SAT-P), and Borderline Personality Disorder Severity Index (BPDSI) were repeated at 6, 12, and 24 months. Statistical analysis was performed with the general linear model. Results showed that most of the differences between combined therapy and single pharmacotherapy at the end of the 32 weeks trial were maintained after 24 months follow-up. The addition of IPT-BPD to medication produced greater effects on BPD symptoms (impulsivity and interpersonal relationships) and quality of life (perception of psychological and social functioning) that endured after termination of psychotherapy. On the contrary, different effects on anxiety symptoms and affective instability were lost after 6 months.

Combined treatment of borderline personality disorder with interpersonal psychotherapy and pharmacotherapy: predictors of response.

Borderline personality disorder (BPD) is characterized by affective instability, impulsive behaviors, and disturbed interpersonal relationships. A previous study of our group found that combined therapy with interpersonal psychotherapy adapted to BPD (IPT-BPD) and fluoxetine was superior to single pharmacotherapy in BPD patients. The aim of the present study was to examine what clinical factors predicted response to combined therapy in patients evaluated in the previous efficacy study. The subgroup of 27 patients allocated to combined therapy was analyzed. Patients were treated for 32 weeks with fluoxetine 20-40 mg/day plus IPT-BPD. Patients were assessed at baseline and week 32 with an interview for demographic and clinical variables, CGI-S, HDRS, HARS, SOFAS, BPDSI, and SAT-P. Statistical analysis was performed with multiple regression. The difference of CGI-S score between baseline and week 32 (∆CGI-S) was the dependent variable. Factors significantly and independently related to ∆CGI-S were the BPDSI total score and the items abandonment, affective instability, and identity. Patients with more severe BPD psychopathology and with a higher degree of core symptoms such as fear of abandonment, affective instability, and identity disturbance have a better chance to improve with combined therapy with fluoxetine and IPT-BPD.

Group interpersonal psychotherapy (IPT-G) for borderline personality disorder: A randomized controlled study.

Recent evidence supported the notion that add-on group therapy should be provided to individuals with borderline personality disorder (BPD) who already undergo individual psychotherapy. The present 20 week-study was aimed to evaluate the efficacy of the adjunction of group interpersonal psychotherapy (IPT-G) to individual interpersonal psychotherapy adapted for BPD - revised (IPT-BPD-R) in comparison with individual IPT-BPD-R alone in a group of BPD patients. In addition, demographical and clinical characteristics that can be considered predictors of response to add-on group therapy were investigated. Forty-six patients were randomly assigned to 1) IPT-BPD-R plus IPT-G or to 2) IPT-BPD-R in the waiting list for IPT-G. Patients were assessed at baseline and after 20 weeks with: the Clinical Global Impression Scale, Severity item (CGI-S); the Social Occupational Functioning Assessment Scale (SOFAS); the Satisfaction Profile (SAT-P); the Borderline Personality Disorder Severity Index (BPDSI); the Modified Overt Aggression Scale (MOAS); the Childhood Trauma Questionnaire - Short Form (CTQ-SF); the Inventory of Interpersonal Problems (IIP-32); and the Reading the Mind in the Eyes Test (RMET). Statistical analyses included: ANOVA for repeated measures to compare score changes of the rating scales within groups (trial duration) and between groups (treatment modalities), and multiple regression analysis to identify which clinical factors are significantly and independently related to the difference of BPDSI score between baseline and week 20 (Δ BPDSI). The significance level was P ≤ 0.05. Both significant within-subjects effects (duration) and between-subjects effects (treatment modalities) were found for the following rating scales: MOAS; BPDSI items "feelings of emptiness", "outbursts of anger," and "affective instability"; RMET; SAT-P items "work" and "sleep, food, free time"; and IIP-32 scale "domineering/controlling". At the multiple regression analysis BPDSI item "impulsivity", RMET, and the subscale "socially inhibited" of the IIP-32 were significantly and independently related to Δ BPDSI score. In conclusion, the add-on of IPT-G produced higher improvement in core BPD symptoms, social cognition, a dysfunctional interpersonal style, and subjective quality of life. Subjects who were less impulsive, less socially inhibited, and with higher abilities in social cognition obtained greater benefits from the adjunction of group therapy.
