integrated intervention for borderline personality disorder and caregivers

Conditions: Borderline Personality Disorder

Summary: this is a prospective, single-arm, open-label study to assess the impact of a group intervention for patients with borderline personality disorder (bpd) and a psycho-educational intervention for their caregivers. once participants complete a comprehensive clinical assessment, the study involves the participation of those with a bpd diagnosis in dialectical behavior therapy (dbt) skills training group, integrated with ongoing routine treatments. a battery of questionnaires is administered before and after the dbt skills training to assess emotion dysregulation, bpd symptoms severity and other clinical variables. simultaneously, caregivers of individuals with bpd take part in the family connections (fc) program. this sub-study follows a previous pilot study conducted at the same centre. family members complete assessment questionnaires at three different time points (i.e., at baseline, at immediately post-intervention and at a 4-month follow-up) in order to evaluate putative positive pre-post changes on burden, grief and other clinical variables. in order to explore biomarkers of bpd and stress-related neurobiological mechanisms, blood samples are collected from the bpd patient group at pre and post intervention. at baseline, a blood sample is also collected to identify stress-related biomarkers among family members.

borderline personality disorder (bpd) has a severe impact on the lives of individuals with this disorder. also caregivers of individuals with bpd and related conditions often experience higher levels of somatic and psychological distress. dialectical behavior therapy (dbt) has been proven to be an effective treatment for bpd and it has been well documented that also the module of skills training is effective in the reduction of symptoms. moreover, one of the most well-established programs to support family members of patients with bpd is family connections (fc). fc showed beneficial effects on severity of depression, well-being and family functioning. the aim of the present study is threefold: 1. to evaluate the implementation of a dbt skills training program as a complementary intervention in routine health care. 2. to assess pre-post changes resulting from a fc intervention in family members of individuals with bpd and to identify predictors of positive outcomes. 3. to explore potential biomarkers associated with bpd and stress-related neurobiological mechanisms among both bpd patients and their family members. participants are recruited at the irccs centro san giovanni di dio fatebenefratelli in brescia. for the dbt skills training, the primary outcome is the reduction of emotion dysregulation. secondary outcomes encompass measures of depression, anxiety, alexithymia, global psychological distress, global functioning, impulsiveness, interpersonal problems and severity of bpd symptoms. in addition, socio-demographics, trauma history and the presence of non-suicidal self injury or suicide attempts are assessed. within the fc group, primary endpoints are burden and grief scores, while secondary endpoints include measurements of depression, alexithymia, global psychological distress, family functioning, and feelings of anger. dbt skills training consists of 24 weekly sessions that incorporate two acceptance-oriented skills (mindfulness and distress tolerance) and two change-oriented skills (emotion regulation and interpersonal effectiveness). the fc program, on the other hand, is a 12-week manualized educational and skills-building support program rooted in the principles of dbt, administered in a group setting to family members of individuals with bpd. group facilitators possess a medical or psychological professional background and have received training in both the dbt and fc programs. in addition to psychological assessments, the study involves the collection of blood samples from the bpd patient group (before and after the intervention). these samples are collected in order to identify potential biomarkers associated with bpd and treatment response, including levels of brain-derived neurotrophic factor (bdnf), expression of pro-inflammatory cytokines and anti-inflammatory cytokines, and c-reactive protein levels. furthermore, the study analyzes stress-related biomarkers such as cortisol levels and investigate epigenetic mechanisms through dna and mirna metilations analysis. in the fc group, a baseline blood sample is also collected to explore stress-related biomarkers.
