Objective: The present study reports on the long-term effects of a mindfulness-based stress reduction (MBSR) program for adult survivors of childhood sexual abuse. Method: Of the study participants, 73% returned to the clinic for a single-session follow-up assessment of depression, posttraumatic stress disorder (PTSD), anxiety, and mindfulness at 2.5 years. Results: Repeated measures mixed regression analyses revealed significant long-term improvements in depression, PTSD, anxiety symptoms, and mindfulness scores. The magnitude of intervention effects at 128 weeks ranged from d = .5 to d = 1.1. Conclusion: MBSR may be an effective long-term treatment for adults who have experienced childhood sexual abuse. Further investigation of MBSR with this population is warranted given the durability of treatment effects described here
