Investigating Effectiveness and Predicting Outcome and Dropout From Systems Training for Emotional Predictability and Problem Solving for Emotional Intensity Difficulties (STEPPS EI) in UK Primary Care.

Systems Training for Emotional Predictability and Problem Solving (STEPPS) for borderline personality disorder (BPD) has been adapted for a primary care setting into a 13-week group treatment for emotional intensity difficulties (STEPPS EI). This is the first study to examine the effectiveness and potential outcome and dropout predictors of STEPPS EI in a primary care setting. Severity of BPD, depression, and anxiety symptoms were measured pre- and postintervention for 148 participants. Treatment completers showed improvements in depression, anxiety, and BPD symptoms with medium to large effect sizes. A predictor of symptom improvement was higher baseline severity for each of the symptom measures. Attending a psychoeducational group prior to STEPPS EI was associated with lower odds of dropout. The findings support the use of STEPPS EI in a primary care setting, with the potential to alleviate the burden from other local services.
