RESUMO
OBJECTIVE: The aim of this study was to explore the effectiveness of schema therapy (ST) in older adults with borderline personality disorder (BPD). METHODS: Multiple baseline case series design with five BPD patients, with a mean age of 66. After a baseline phase with random length, patients received weekly ST sessions for a year, followed by follow-up sessions during 6 months. Participants rated the credibility of negative core beliefs weekly; various secondary outcome measures were assessed every 6 months (severity of BPD, early maladaptive schemas, schema modes, personality functioning, maladaptive personality traits, psychological distress and quality of life), and BPD diagnosis was assessed before baseline and after follow-up. Data were analysed with mixed regression analyses and paired t-tests. RESULTS: Results revealed that ST led to a significant decrease in credibility of negative core beliefs, with high effect sizes. All participants remitted from their BPD diagnosis. CONCLUSION: This is the first study exploring the effectiveness of ST for BPD in older adults, and it suggests that ST can be a powerful intervention for this group of patients.
