Summary Sleep disturbance is commonly reported by participants with post‐traumatic stress disorder, but objective evidence of poor sleep is often absent. Here we compared self‐report and actigraphic evaluations of sleep between veterans with post‐traumatic stress disorder and controls. Participants reported their sleep retrospectively for the month before the recording night and on the recording night. On the recording night, they wore an Actiwatch‐64 and were instructed to press the marker button upon getting into bed, each time they awoke, and at their final awakening. The post‐traumatic stress disorder group reported much worse sleep than controls on the Pittsburgh Sleep Quality Index for the previous month and somewhat poorer sleep on the recording night. However, on the recording night, neither diary nor actigraphic measures of number of awakenings, total time in bed, nor time lying awake after sleep onset differed between participants with and without post‐traumatic stress disorder. Diary‐reported number of awakenings was fewer than actigraphically captured awakenings. These results suggest a memory bias towards remembering worse sleep on the nights before the recording night.
