Background and purpose: To determine the sleep response to caffeine in individuals vulnerable to stress-related sleep disturbance as measured by polysomnography.Patients and methods: Eleven healthy individuals without insomnia scoring low (4 women, mean age= 32.64 +/- 15.46 years) and 10 healthy individuals also without insomnia scoring high (6 women, mean age=34.20 +/- 13.73 years) on a measure of vulnerability to stress-related sleep disturbance were studied in a laboratory protocol. A moderate-low dose of caffeine (3 mg/kg) was administered 1 h prior to lights-out and compared to a counterbalanced control night with each condition separated by 1 week. Standard polysomnographic measures were assessed (i.e. total sleep time, sleep efficiency, latency to persistent sleep, and sleep stage percentages) for both control and caffeine nights.Results: There were no between-group differences in sleep on the control night. Importantly, individuals reporting vulnerability to stress-related sleep disturbance had significantly prolonged latency to persistent sleep in response to the caffeine challenge (interaction; P
