Psychological treatment of chronic posttraumatic stress disorder in victims of sexual aggression

The aim of this research was to test the comparative effectiveness of two therapeutic modalities in the treatment of chronic posttraumatic stress disorder in victims of sexual aggression: (a) self-exposure and cognitive restructuring and (b) progressive relaxation training. The sample consisted of 20 patients (victims of rape in adulthood or adult victims of childhood sexual abuse) selected according to DSM-III-R criteria. A multigroup experimental design with repeated measures (pretreatment, posttreatment, and 1-, 3-, 6-, and 12-month follow-up) was used. Most treated patients improved, but the success rate was higher in all measures in the exposure and cognitive restructuring group immediately on posttreatment and at follow-up. Implications of this study for clinical practice and future research in this field are commented on.
