STAIR/MPE is a sequential, two-phase treatment based in a developmental model which is designed to be sensitive to the disturbances in attachment, emotion regulation, and interpersonal functioning that survivors of childhood or chronic interpersonal violence often bring to treatment. Phase 1: Skills Training in Affective and Interpersonal Regulation (STAIR) is designed to enhance day-to-day functioning by building emotion regulation capacities and interpersonal skills and provides a window of opportunity for client and therapist to develop a strong therapeutic alliance. Phase 2 of treatment is a modified version of prolonged exposure (MPE).

Improvement in emotion regulation, self-efficacy, anger expression, interpersonal problems, and perceptions of social support.
