Effectiveness of Short-Term Inpatient Psychotherapy Based on Transactional Analysis With Patients With Personality...

Controlled studies on the effectiveness of inpatient psychotherapy with patients with personality disorders (PD) are rare. This study aims to compare 3-month short-term inpatient psychotherapy based on transactional analysis (STIP-TA) with other psychotherapies (OP) up to 36-month follow-up. PD patients treated with STIP-TA were matched with OP patients using the propensity score. The primary outcome measure was general psychiatric symptomatology; secondary outcomes were psychosocial functioning and quality of life. In 67 pairs of patients, both STIP-TA and OP showed large symptomatic and functional improvements. However, STIP-TA patients showed more symptomatic improvement at all time points compared to OP patients. At 36 months, 68% of STIP-TA patients were symptomatically recovered compared to 48% of OP patients. STIP-TA outperformed OP in terms of improvements in general psychiatric symptomatology and quality of life. Superiority of STIP-TA was most pronounced at 12-month follow-up, but remained intact over the course of the 3-year follow-up.
