The family alliance as a facilitator of therapeutic change in systemic relational psychotherapy for borderline personality disorder: A case study

Managing the Therapeutic Alliance is often complex when it comes to the treatment of borderline personality disorder (BPD), but the alliance is crucial for the success of the therapy. Combined individual and family interventions have been shown to be very useful in treating of these cases. This study has two objectives. First, to describe how the family therapeutic alliance facilitates therapeutic change through family psychotherapy for families with a member diagnosed with BPD. Second, to analyze how the therapeutic change achieved through combined individual and family systemic relational psychotherapy affects the individual functioning of the patient with BPD. This single case study used the System of Observation of Family Therapy Alliances (SOFTA‐o) to analyze the therapeutic alliance, along with two semi‐structured clinical interviews, one at the beginning and one at the end of therapy. Results show a dynamic and positive evolution of the therapeutic alliance throughout the therapeutic process and how this alliance facilitated therapeutic change, both reducing the symptomatology of the patient with BPD and improving family communication and functioning. Results contribute to highlighting the importance of including family therapy as an intervention unit in protocols for patients with BPD.
