*The Institute for Trauma and Stress at the NYU Child Study Center is offering short-term psychotherapy treatment to women aged 22-65 meeting DSM-IV criteria for Post Traumatic Stress Disorder due to childhood physical and/or sexual abuse. Subjects will participate in a research study and be randomly assigned to one of three treatments. The three treatments are: [list][*]Skills Training for Affect and Interpersonal Functioning (STAIR), which focuses on helping the individual strengthen and build skills in managing feeling and improving interpersonal relationships combined with Supportive Counseling (SC); [*]Modified Prolonged Exposure (MPE), which focuses on developing narratives of abuse history and completing an "emotional processing" of the trauma in a safe environment combined with Supportive Counseling (SC); [*]A combination of STAIR and MPE.[/list:u] Researchers wish to learn which of these treatments is most effective and for whom each treatment is most helpful. All three treatments include 16 hour-long individual sessions. Participants must not have a thought disorder, eating disorder, engage in cutting behavior, or have made a suicide attempt in the past six months.
