Current Knowledge/Study Rationale: Sleep impairment has been cited as the most-often reported symptom of posttraumatic stress disorder (PTSD). It is associated with severe distress, impaired attention and concentration, and poorer treatment outcomes. The primary study aim was to assess the relative contributions of objective and self-reported measures of nocturnal sleep duration to objectively measured deficits in sustained attention in a sample of female interpersonal violence survivors with PTSD.
Study Impact: Results revealed that self-reported, daily estimations of sleep, but not objectively or globally measured sleep impairment, is directly related to attention in this PTSD sample. Assessing sleep impairment on a daily basis throughout treatment may provide clinically relevant information in evaluating daytime symptoms and guiding treatment decisions.
