Reaction to trauma: a cognitive processing model.   总被引:7,自引:0,他引:7  
We integrated existing cognitive processing models of posttrauma reactions into a longitudinal model. Data were obtained after a multiple shooting in a city office block. The subject group comprised 158 office workers who were in the building at the time of the shootings. The methodology of this research was a repeated measures survey, with data collection at 4, 8, and 14 months posttrauma. Measures included the Impact of Events Scale (IES) and the Symptom Checklist-90-Revised. A path analysis was performed with the IES as an indication of cognitive processing. Intrusion and avoidance were shown to mediate between exposure to trauma and symptom development. Intrusion was also found to be negatively related to subsequent symptom levels. The findings provide provisional support for a cognitive processing model.  相似文献

To study malevolent representations, earliest memories were reliably coded on scales of affect tone. Ss were diagnosed with borderline personality disorder: 31 without and 30 with concurrent major depression. Nonborderline comparison subjects had either major depressive disorder (n = 26) or no psychiatric diagnosis (n = 30). Borderline subjects were discriminated from comparison subjects by their more malevolent representations; they more frequently produced memories involving deliberate injury; and they portrayed potential helpers as less helpful. Results suggest the diagnostic significance of malevolent representations, which need to be explained by any theory of borderline personality disorder.  相似文献

The hypothesis that psychosis-prone students demonstrate a pattern of exaggerated perceptual asymmetry across both left- and right-hemisphere dichotic-listening tasks (consonant-vowel [CV] and tonal contour discrimination) was investigated. Subjects who scored high on the Perceptual Aberration or Magical Ideation scale or both (n = 20) demonstrated a significantly exaggerated right-ear advantage on a CV task in relation to normal control subjects (n = 27) but showed a reduced left-ear advantage on a tone task. The hypothesis of exaggerated functional lateralization across hemispheres in the psychosis-prone subjects was not supported, but the results are consistent with a hypothesis of left hemisphere overactivation in this sample.  相似文献

Forty-one nonpsychiatric subjects, 38 probands with schizophrenia, and 99 of their relatives were studied. Oculomotor functioning was bimodally distributed for probands and relatives. Oculomotor dysfunction was not present in all families with a schizophrenic proband. In those families in which it was present, there were significant phenotypic correlations between oculomotor functioning and schizophrenia-related characteristics. The patterns of familial resemblance in the families in whom oculomotor dysfunction was present were consistent with nonadditive genetic variance contributing both to oculomotor dysfunction and to the relationship between oculomotor dysfunction and clinical symptoms. These results suggest that schizophrenia may be etiologically heterogeneous and that oculomotor dysfunction may help to identify nonadditive genetic variance for this disorder.  相似文献

We examined the role of reporting bias in hypnotic negative hallucinations by using a paradigm in which reporting bias was assessed independently of perceptual change. In Experiment 1, highly hypnotizable subjects reported significant loudness reductions when tested for hypnotic deafness. Later, however, these subjects biased their reported loudness reductions in the absence of perceptual change, and their reporting bias scores were almost as large as their hypnotic deafness reports. Subjects also biased their ratings of strategy use. In Experiment 2, ratings of blindness given in response to a hypnotic negative visual hallucination suggestion were significantly correlated with reporting bias scores obtained in this paradigm. Although hypnotic blindness and hypnotic deafness correlated significantly, the partial correlation between these variables was nonsignificant when reporting bias scores were statistically controlled. Theoretical implications are discussed.  相似文献

Twenty depressed patients with major depressive disorder, 20 nondepressed matched control subjects, and 17 patients with anxiety disorders were compared in different measures of social problem solving. Problem solving was assessed with the Means-Ends Problem-Solving Test (Study 1), the solution of personal problems, and a problem-solving questionnaire (Study 2). Results showed that, as predicted, depressed subjects suffered from a deficit in problem solving in all three measures. The majority of these deficits were also displayed by the clinical control group rather than being specific to a diagnosis of depression. However, depressed subjects produced less effective solutions than did normal and clinical control subjects. The results suggest that depressed and anxious patients may have difficulties at different stages of the problem-solving process.  相似文献

To test Coyne's (1976b) theory of depression, students' levels of depressive symptoms, reassurance seeking, and self-esteem were assessed at Time 1, and their same-gender roommates' appraisals of them were assessed 5 weeks later. Mildly depressed students engaged in the type of reassurance seeking described by Coyne. Among men, but not women, mildly depressed students were rejected if they strongly sought reassurance and had low self-esteem but not if they did not seek reassurance or had high self-esteem. Although induction of depressed symptoms in roommates did occur, this contagion effect did not account for the depression-rejection relationship. The prediction that unsupportive, intolerant, or unempathic others would be particularly likely to respond with rejection to reassurance-seeking depressed students with low self-esteem received partial support. Implications for future work on the interpersonal aspects of depression are discussed.  相似文献

This article uses a psychoanalytic ego-psychological framework to examine the regression experienced by an individual group member and the defenses mobilized to counter it, focusing in particular on the defensive functions of constituting leadership somewhere in the group. The leader, regarded as an internal object in the member's object world, is hypothesized to be a combination of projected and personified part-objects and at the same time an integrating whole object. Various phenomena of group life are discussed from this viewpoint, notably the lability of the relationship with the leader, the externalization of various endopsychic regulations, and the conditions supporting the defensive utility of the leader for the group member. The foundation for the emergence of social roles and consensual perception of the group and its leadership becomes apparent. A strictly intrapsychic view is maintained throughout.  相似文献

The author discusses how subgroups represent the basic focus of the systems-centered group therapist. Particular attention is given to boundary issues and to how therapy takes place by facilitating the process of discriminating, communicating, and integrating perception of differences in the apparently similar and similarities in the seemingly different. Communication occurs at the boundaries between systems at all levels of the hierarchy: the group, the subgroup, and its members. Clinical vignettes are provided to illustrate important process issues, such as work with difficult patients, levels of intervention, and group resistance and defense.  相似文献

The author shows how object relations group therapy focuses on primitive defense mechanisms that shape the group-entity image or "basic assumptions group." Such primitive defense mechanisms as splitting, projective identification, omnipotent denial, projection, and introjection are the mental resources to protect the endangered self and the threatened objects from the fantasized imminent destruction. Object relations group psychotherapy addresses those defenses and the underlying psychotic anxieties, offering members opportunities to search for other ways to respond to their primitive fears. The author introduces two extensive clinical vignettes to illustrate how object relations group methods are different from other group-centered psychoanalytic techniques. He concludes by commenting on future theoretical refinements and on the problems in the professional practice of this modality.  相似文献
