Description: Psychological responses to motor vehicle crashes are affected by an individual's appraisal of the crash and their coping strategies. In this study, a model based on Horowitz's (1986) Stress Response Theory and Lazarus and Folkman's (1984) cognitive theory of stress, appraisal, coping, and emotion was tested. The effects of appraisal and coping on Post-Traumatic Stress Disorder (PTSD) were examined in drivers and passengers at three time periods: between two and five days, four weeks, and eight weeks after the crash. The subsequent effects of PTSD on appraisal and coping were also examined.

Respondents consisted of 154 adult male and female drivers and passengers, aged 18 to 74, admitted to and discharged from three major trauma centers on the Northern East Coast following motor vehicle crashes. Data were generated through appraisal, coping, and PTSD questionnaires and were analyzed using analysis of variance for repeated measures and Linear Structural Relations (LISREL).

Findings in relation to the tested hypotheses and research questions were as follows: (1) at two to five days following the crash (time 1), appraisal had a direct effect on PTSD and an indirect effect on PTSD through coping; (2) at four weeks following the crash (time 2), appraisal had a direct effect on PTSD and an indirect effect on PTSD through coping; (3) at eight weeks following the crash (time 3), appraisal had a direct effect on PTSD but did not have an indirect effect on PTSD through coping; (4) PTSD at time 1 had a direct effect on coping at time 2 and PTSD at time 2 had a direct effect on coping at time 3; (5) PTSD at time 1 had a direct effect on appraisal at time 2 and PTSD at time 2 had a direct effect on appraisal at time 3; (6) PTSD at time 1 did not have an indirect effect on coping at time 2 through appraisal at time 2; (7) PTSD at time 2 did not have an indirect effect on coping at time 3 through appraisal at time 3; (8) appraisal did not change over time; (9) emotion-focused coping did not change over time; (10) problem-focused and seeks social support coping changed over time; and (11) intrusion changed over time while avoidance remained unchanged.

The hypothesized model fit the data in four of five analyses. Based on the findings of this study, implications were discussed and recommendations for future research were suggested. (Abstract shortened by UMI.).
