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.

Interpersonal Psychotherapy as a Single Treatment for Borderline Personality Disorder: A Pilot Randomized-Controlled Study.

Recent guidelines share the recommendations that psychotherapy plays a central role in the treatment of borderline personality disorder (BPD). In recent years, interpersonal psychotherapy adapted for treating BPD (IPT-BPD) was added to specific psychotherapies and was tested in combination with pharmacotherapy. The present study is aimed to assess the efficacy of IPT-BPD revised (IPT-BPD-R) as single treatment in a sample of BPD patients. Results obtained in a group of patients receiving IPT-BPD-R were compared with those observed in a control group in waiting list plus clinical management (WL/CM). Forty-three BPD subjects were randomly allocated to one of the two arms. Patients were assessed at baseline and after 10 months with the following assessment instruments: Clinical Global Impression Scale, Severity item (CGI-S), Social Occupational Functioning Assessment Scale (SOFAS), Borderline Personality Disorder Severity Index (BPDSI), Barratt Impulsiveness Scale, version 11 (BIS-11), Modified Overt Aggression Scale (MOAS), and Self Harm Inventory (SHI). Statistical analysis was performed with one-way analysis of variance (ANOVA) or chi-square test to compare baseline characteristics of the two treatment groups. Comparison of score changes at the end of the trial between the two groups was calculated for each rating scale with the analysis of variance for repeated measures. Seven patients (16.3%) discontinued the treatment in the first month of the trial for non-adherence. We found a significant effect within subjects (trial duration) for all rating scales, except for the MOAS. A significant effect between subjects (treatment modality) was found for CGI-S; SOFAS; BIS-11 total score and subscale "non-planning impulsivity"; BPDSI total score and items "interpersonal relationships," "impulsivity," and "identity." So, results showed differences between groups in favor of psychotherapy in terms of reduction of severity of general psychopathology, improvement of social and occupational functioning, and decrease of global BPD symptoms and three specific domains. On the other hand, we did not find any differences between groups for self-harm behaviors and aggressive behaviors.

How Interpersonal Psychotherapy Changes the Brain: A Study of fMRI in Borderline Personality Disorder.

Background: Recent guidelines and systematic reviews suggest that disorder-specific psychotherapeutic interventions are the first choice in the treatment of borderline personality disorder (BPD). The aim of this study is to examine brain activity changes in BPD patients (DSM-5) who received a revised BPD-adapted interpersonal psychotherapy (IPT-BPD-R) compared with patients on the waiting list. Methods: Forty-three patients with a BPD diagnosis (DSM-5) were randomly assigned to IPT-BPD-R (n = 22 patients) or the waiting list with clinical management (n = 21 patients) for 10 months. Both groups were tested before and after treatment with the Social and Occupational Functioning Assessment Scale (SOFAS), the Clinical Global Impressions-Severity of Illness scale (CGI-S), the Borderline Personality Disorder Severity Index (BPDSI), the Barratt Impulsiveness Scale-version 11 (BIS-11), and the Autobiographical Interview. Both groups underwent pre- and posttreatment functional magnetic resonance imaging (fMRI) testing. The fMRI task consisted of the presentation of resolved and unresolved life events compared to a neutral condition. All structural and functional images were analyzed using Statistical Parametric Mapping 12 software, which interfaces with MATLAB. Clinical data were analyzed using analysis of variance for repeated measures. Patients were recruited between September 2017 and April 2019. Results: In clinical results, for the 4 rating scales, a significant between-subject effect was found in favor of the IPT-BPD-R-treated group (CGI-S: P = .011; BPDSI: P = .009; BIS-11: P = .033; SOFAS: P = .022). In fMRI results, posttreatment versus pretreatment for the contrast unresolved life event versus neutral condition showed significantly decreased right temporoparietal junction (rTPJ: x = 45, y = -51, z = 36) (P = .043) and right anterior cingulate cortex (rACC: x = -4, y = 37, z = 8) activity (P = .021). Conclusions: IPT-BPD-R appears to be effective in treating BPD symptoms, and these clinical effects are reflected in the functional changes observed with fMRI. Brain areas that showed modulation of their activity are the rTPJ and rACC, which are involved in mentalization processes that are fundamental to BPD pathology.

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.
