Outcome Measures
Primary Outcomes (1)
Prepulse Inhibition
To calculate prepulse inhibition (PPI), first an O-EMG response score (O-EMG-R) for each trial was calculated. O-EMGR was measured in microvolts and each value was subjected to a square root transformation. For each participant, the mean O-EMG-R scores were calculated for both startle alone and prepulse + startle trials across the entire session. PPI is a ratio and was calculated by the formula below: PPI=(mean OEMG-R score on prepulse+startle trials-mean OEMG-R on Startle alone trials)/mean OEMG-R on startle alone trials. A negative value on this PPI ratio is indicative of greater prepulse inhibition. Means and SEs below reflect estimated means and SEs for the PTSD group and trauma control group from the ANOVA conducted with menstrual phase and the PTSD group X menstrual phase interaction included in the model.
This measure was assessed twice for each participant, once in the midluteal phase of the menstrual cycle and once in the early follicular phase of the menstrual cycle, up to approximately 20 days apart.
