Psychophysiological assessment data, including heart rate (HR), blood pressure, and frontal electromyogram (EMG) responses to mental arithmetic, idiosyncratic audiotape descriptions of motor vehicle accidents (MVAs), and a standard videotape of MVAs, were collected on 105 injured victims of recent MVAs and 54 non-MVA controls. Their data replicated data(More)
This small-scale study investigates the relationships between the heart rate of motor vehicle accident survivors presenting in the emergency department (ED) and acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) symptom severity. It also examines the relationships between the survivor's heart rate in the ED and peritraumatic dissociation(More)
The primary purpose of this report was to determine the extent of psychiatric morbidity and comorbidity among a sample of recent victims of motor vehicle accidents (MVAs) in comparison to a nonaccident control population. Victims of recent MVAs (N = 158), who sought medical attention as a result of the MVA, were assessed in a University-based research(More)
We have examined data from 107 motor-vehicle accident (MVA) victims with regard to whether the presence of comorbid depression is important clinically, and with regard to whether the threshold for diagnosing the comorbid depression should be raised because of symptom overlap between posttraumatic stress disorder (PTSD) and major depression. Of the 62 MVA(More)
One hundred forty five individuals who sought medical attention as a result of a motor vehicle accident (MVA), and who were initially assessed 1 to 4 months post-MVA, were followed up prospectively for 6 months to determine how many of the 55 with posttraumatic stress disorder (PTSD) and the 43 with sub-syndromal PTSD would remit and what variables would(More)
Ninety-eight victims of recent motor vehicle accidents (MVA), who sought medical attention as a result of the MVA, were followed up prospectively 6 months after the initial assessment, using Keller, Lavori, Friedman, Nielsen, Endicott, McDonald-Scott and Andreasen's (Archives of General Psychiatry, 44, 540-548, 1987) LIFE methodology so that month-by-month(More)
Investigators have recently identified a two-factor structure underlying posttraumatic stress symptoms through the use of exploratory factor analysis. [Taylor et al. (1988). The structure of posttraumatic stress symptoms. Journal of Abnormal Psychology, 107, 154-160]. These two factors, which were labeled as Intrusion and Avoidance, and Hyperarousal and(More)
In order to investigate the effects of the initiation of litigation and its settlement on victims of motor vehicle accidents (MVAs), we followed up 132 MVA victims from an initial assessment 1 to 4 months post-MVA for 1 year. Of the 67 who had initiated litigation, 18 (27%) settled within the 12 months, while 49 still had litigation pending; 65 never(More)
This study sought to replicate past research that has shown differences in physiological responsiveness among survivors of motor vehicle accidents (MVAs) with posttraumatic stress disorder (PTSD) and those survivors who do not develop this disorder. Such physiological differences have been found specifically with heart rate (HR) reactivity. This study also(More)
This study investigated the effect of traumatic brain injury on the development of posttraumatic stress disorder (PTSD). Subjects were 107 motor vehicle accident survivors including 38 individuals who were diagnosed with posttraumatic stress disorder (PTSD). Neuropsychological testing was administered to all subjects during an initial diagnostic evaluation.(More)
