STEPPS for Borderline Personality Disorder: A Pragmatic Trial and Naturalistic Comparison With Noncompleters.

ABSTRACT

Systems Training for Emotional Predictability and Problem Solving (STEPPS) is a group psychotherapy approach that is effective for patients with borderline personality disorder (BPD) in a public health care setting. The sample in this study comprised 118 outpatients with BPD who were asked to participate in a Spanish-adapted version of STEPPS for 18 months, a psychotherapy program that could be added to their usual psychiatric intervention. They were divided into an experimental group who participated in STEPPS, and a control group, who received treatment as usual. Several variables were collected and the Borderline Evaluation of Severity Over Time (BEST) scale was administered at pretest, Months 3 and 6, posttest (Month 18), and 2-year follow-up (Month 42), after which a post hoc data analysis was carried out. The STEPPS program improved the as-usual treatment provided previously, and the results were cost-effective. A higher educational level and good patient collaboration predicted better outcome.
