چکیده انگلیسی

Past research into the psychological consequences of traumatic events has largely focused on post-traumatic stress disorder (PTSD), although other anxiety disorders and depression are also common in the aftermath of trauma. Little is known about differential predictors of these conditions. The present study investigated the extent to which theoretically derived cognitive variables predict PTSD, phobias and depression after motor vehicle accidents. The cognitive predictors were compared to a set of established, mainly non-cognitive predictors. In addition, we tested how disorder-specific the cognitive predictors are. Participants (n=101n=101) were interviewed within a year after having been injured in a motor vehicle accident. Diagnoses of PTSD, travel phobias and depression, symptom severities and predictor variables were assessed with self-report questionnaires and structured interviews. In multiple regression analyses, the sets of cognitive variables derived from disorder-specific models explained significantly greater proportions of the variance of the symptom severities than the established predictors (PTSD 76% vs. 45%, depression 72% vs. 46% and phobia 66% vs. 40%), and than cognitive variables derived from the models of the other disorders. In addition, the majority of individual cognitive variables showed the expected pattern of differences between diagnostic groups. The results support the hypothesis that disorder-specific sets of cognitive factors contribute to the development and maintenance of PTSD, phobias and depression following traumatic events.

مقدمه انگلیسی

Traumatic events such as injury in a motor vehicle accident (MVA) can lead to a range of psychological problems. Past research has largely focused on post-traumatic stress disorder (PTSD) (see Blanchard & Hickling, 2004), but other anxiety disorders, depression and substance use disorders are also common consequences of trauma (e.g. Blanchard et al., 2004; Mayou, Bryant, & Ehlers, 2001; O’Donnell, Creamer, Pattison, & Atkin, 2004). The question of what factors predict which of these psychological problems trauma survivors will develop has rarely been addressed in previous research, and findings have been inconsistent (Mayou et al., 2001; McFarlane, Atchison, & Yehuda, 1997; O’Donnell, Creamer, & Pattison, 2004; Shalev et al., 1998). Cognitive theories of emotional disorders postulate content specificity, i.e. specific sets of cognitions are thought to be involved in the development and maintenance of each disorder (e.g., Beck, 1976; Clark, 1999). In recent years, several cognitive models of PTSD (for a review see Brewin & Holmes, 2003), other anxiety disorders (e.g., Beck, Emery, & Greenberg, 1985; Clark, 1999) and depression (e.g., Beck, 1990; Teasdale, 1988) have been developed. This raises the question of whether cognitive variables specified in these models are useful in predicting differential psychological outcomes after traumatic events. Most studies of predictors of psychological problems after accidents have focused on pre-accident risk factors, characteristics of the trauma, the emotional response during the trauma, or post-accident stressors (e.g., Blanchard et al. (1995) and Blanchard et al. (1996); ; Schnyder, Moergeli, Klaghofer, & Buddeberg, 2001). In a recent meta-analysis, seven variables were identified as the best-established predictors2 of PTSD following trauma: prior trauma, prior psychological adjustment, family history of psychopathology, perceived life threat during the trauma, post-trauma social support, peritraumatic emotional responses and peritraumatic dissociation (Ozer, Best, Lipsey, & Weiss, 2003). The meta-analysis included data from very diverse populations of trauma survivors. Studies looking specifically at PTSD following MVA have found similar patterns of results (see Blanchard & Hickling, 2004). The present study aimed to extend past research into the psychological consequences of MVA by (a) simultaneously focusing on three different disorders with onset after accidents, namely PTSD, travel phobias and depression, as well as (b) investigating the role of cognitive factors derived from theoretical models and comparing their predictive power to that of the established PTSD predictors identified in Ozer et al.'s (2003) meta-analysis. In addition, we tested how disorder-specific these cognitive factors are. Cognitive-behavioral models of PTSD, phobias, and depression
