|Pre-trauma Predictor Variable Means and SDs for Individuals Exposed to a Traumatic Event (N = 99)|
|Pre-tone level (bpm)||71.6||11.6|
|Mean response (√bpm)||0.6||0.9|
|Pre tone level (μS)||7.2||5.6|
|Mean response (√μS)||0.6||0.3|
|Trials to criterion||9.7||4.2|
|Mean response (√μV)||2.3||1.7|
|SC Orienting Response||0.6||0.7|
|Response to CS + trials|
Note: SCL-90-R GSI = Symptom Checklist 90-Revised, Global Severity Score; BDI = Beck Depression Inventory; WAIS-R EST-IQ = Estimated WAIS-R Full Scale IQ from Shipley Institute of Living Scale; STAI-S = State/Trait Anxiety Inventory-State score; bpm = beats per minute; S = Siemens; V = volts; SC = skin conductance; HR = heart rate; Orienting Response = mean response to first presentation of the CS + and the CS- during the habituation phase; Acquisition and extinction response to CS + trials = mean response to CS + trials during the acquisition and extinction phases, respectively; habituation, acquisition, and extinction differential responses = the mean CS interval response to CS + trials minus the mean CS interval response to CS- trials for the habituation, acquisition, and extinction phases, respectively; CS = conditioned stimulus.
