Twenty‐five Vietnam combat veterans with chronic severe posttraumatic stress disorder (PTSD) completed a sleep self‐report questionnaire on admission to an inpatient treatment program. Between 1 and 2 months later each spent 3 or more nights in the sleep laboratory. When self‐report and laboratory findings were compared, significant relationships were observed between sleep schedule items such as time‐to‐bed/time‐out‐of‐bed and polysomnographic measures of sleep. In contrast, global ratings of sleep quality were generally unrelated to polysomnographic measures. These findings may have implications for survey research assessing sleep quality in traumatized populations.
