- Brief Summary
Sexual assault victims (SAV) have an elevated risk of developing posttraumatic stress disorder (PTSD). Trauma-focused cognitive-behavioural therapy (CBT) is an effective first-line treatment for this pathology. However, although sleep disturbances are a common complaint in SAV with PTSD, trauma-focused CBT does not directly address this symptom. Posttraumatic nightmares are widespread among SAV. Trauma-related sleep disturbances are associated with significant impairment in general functioning and quality of life (mental and physical health), and contribute to the maintenance of PTSD symptoms. This study evaluates the efficacy of sequential nightmare therapy (imagery rehearsal therapy; IRT) and trauma-focused CBT, in comparison to CBT alone. Forty-two SAV suffering from PTSD and sleep difficulties were recruited and randomly assigned to the experimental (IRT+CBT) or control condition (waiting period followed by CBT alone). Participants were administered a clinical interview and a series of questionnaires assessing PTSD symptoms, general functioning and quality of life.
