Outcome Measures

Primary Outcomes (2)

  • Physiological Posterior Probability of Posttraumatic Stress Disorder (PTSD) as Determined From Psychophysiologic Responses During Script-Driven Mental Imagery at Month 1

    The posterior probability of developing PTSD was determined for each participant from a composite of psychophysiological responses during script-driven mental imagery of traumatic events (two exemplars) that included assessments of heart rate response in beats per minute, skin conductance response in microSiemens, and corrugator and left lateral frontalis facial muscle electromyogram (EMG) responses in microVolts. Responses for the two traumatic scripts were averaged and square-root transformed for analysis. Responses during personal traumatic imagery of previously studied individuals with and without current PTSD were used to calculate each participant's posterior probability of being classified as PTSD.

    Month 1

  • Physiological Posterior Probability of PTSD as Determined From Psychophysiologic Responses During Script-Driven Mental Imagery at Month 3

    The posterior probability of developing PTSD was determined for each participant from a composite of psychophysiological responses during script-driven mental imagery of traumatic events (two exemplars) that included assessments of heart rate response in beats per minute, skin conductance response in microSiemens, and corrugator and left lateral frontalis facial muscle electromyogram (EMG) responses in microVolts. Responses for the two traumatic scripts were averaged and square-root transformed for analysis. Responses during personal traumatic imagery of previously studied individuals with and without current PTSD were used to calculate each participant's posterior probability of being classified as PTSD.

Study Arms (2)

Propranolol

EXPERIMENTAL

Following the occurrence of an acute psychologically traumatic event, an initial dose of short-acting propranolol 40 mg orally then one hour later, long-acting propranolol 60 mg capsule orally on Day 1 followed by a 19-day course of long-acting propranolol starting with 120 mg every morning and evening for 10 days, and then tapering to 120 mg in the morning and 60 mg in the evening for 3 days, then 60 mg in the morning and 60 mg the evening for 3 days, then 60 mg in the morning for 3 days.

Drug: Propranolol

Placebo

PLACEBO COMPARATOR

Following the occurrence of an acute psychologically traumatic event, an initial dose of placebo-matching short-acting propranolol 40 mg orally then one hour later, placebo-matching long-acting propranolol 60 mg capsule orally on Day 1 followed by a 19-day course of placebo-matching long-acting propranolol starting with 120 mg every morning and evening for 10 days, and then tapering to 120 mg in the morning and 60 mg in the evening for 3 days, then 60 mg in the morning and 60 mg the evening for 3 days, then 60 mg in the morning for 3 days.

Drug: Placebo
