The current study examined patterns and outcomes of emotional activation and habituation during imaginal exposure for posttraumatic stress disorder (PTSD). Participants were 16 women with borderline personality disorder (BPD), PTSD, and recent suicidal and/or self-injurious behavior who received imaginal exposure for PTSD concurrently with dialectical behavior therapy. The intensity of global distress and 6 specific emotions were assessed before and after imaginal exposure trials. Results indicated that significant within-session habituation (WSH) occurred for global distress (Hedge's g effect size = -2.52) and fear (g = -0.80), whereas significant between-session habituation (BSH) occurred for global distress (g = -2.18), fear (g = -1.89), guilt (g = -1.14), shame (g = -0.74), and disgust (g = -0.41). BSH significantly predicted PTSD diagnostic status at posttreatment, whereas activation and WSH were unrelated to outcome. Clients who remitted from PTSD showed significantly more BSH in global distress than nonremitters ((2) = .39). In addition, remitters reported reductions in sadness and anger across trials, whereas sadness and anger increased for those who did not remit ((2) = .54 and .40, respectively). Overall, BPD clients exhibited patterns of activation and habituation during imaginal exposure comparable to other client populations, and there was no evidence of persistent emotional engagement or habituation problems. Resumen El presente estudio examino patrones y resultados de activacion emocional y habituacion durante exposicion imaginaria para el trastorno por estres post-traumatico (TEPT). Las participantes fueron 16 mujeres con trastorno de personalidad limitrofe (TPL), TEPT, y conducta suicida y/o autolesiva reciente que recibieron exposicion imaginaria para TEPT simultaneamente con Terapia Conductual Dialectica. La intensidad del estres global y 6 emociones especificas fueron evaluadas antes y despues de los ensayos de exposicion imaginaria. Los resultados indican que ocurrio habituacion significativa dentro de la sesion (HDS) para estres global (tamano del efecto de la g de Hedge = -2.52) y miedo (g = -0.80), mientras que ocurrio habituacion entre sesiones significativa (HES) para estres global (g = -2.18), miedo (g = -1.89), culpa (g = -1.14), verguenza (g = -0.74), y repulsion (g = -0.41). HES predijo significativamente el estado del diagnostico TEPT en el post-tratamiento, mientras que activacion y HDS no estuvieron relacionadas con los resultados. Lo clientes que remitieron del TEPT mostraron significativamente mas HES en estres global que quienes no remitieron (?(2) = .39). Ademas, las pacientes que remitieron reportaron disminucion de la tristeza y la rabia a traves de los ensayos, mientras que la tristeza y la rabia aumentaron para aquellos que no remitieron (?(2) = .54 y .40, respectivamente). En general, las clientas con TPL exhibieron patrones de activacion y habituacion durante exposicion imaginaria comparables a otras poblaciones de clientes, y no hubo evidencia de compromiso emocional persistente o problemas de habituacion.
