[Investigation of the cognitive process in selection of stress coping behavior].

The purpose of this study was to explore the cognitive process in selection of stress coping behavior. Subjects were 182 undergraduate students, who were asked to answer the questionnaire about their own stress experience and coping behavior. Factor analysis showed that the cognitive process in selection of coping behavior included four factors: "Expectation of positive outcome", "Expectation of emotion regulation", "Selection of habitual coping", "Selection in the elimination". Regression analysis showed that the score of "Expectation of positive outcome" was negatively correlated with stress response, the score of "Selection in the elimination" was positively correlated with stress response. Furthermore, interaction between the individual differences of cognitive process and coping behavior was found. People who engaged in emotion-focused coping style with elimination thinking felt more stressful than the others.

Pathologic characteristics and surgical indications of superacute type A intramural hematoma.

BACKGROUND: The treatment policy for acute intramural hematoma involving the ascending aorta remains controversial. METHODS: This study compared the pathologic characteristics of intramural hematoma with those of acute aortic dissection with a false lumen. The study group comprised 69 patients with intramural hematoma and 156 with acute aortic dissection who underwent emergency operation between 1995 and 2003. RESULTS: Patients were significantly older in the intramural hematoma group than in the dissection group (67.7 +/- 7.2 years compared with 59.8 +/- 11.6 years; p < 0.0001). Pericardial hemorrhage was present in a higher proportion of patients in the intramural hematoma group than in the dissection group (66.7% compared with 50.6%; p = 0.0257). Three patients (4.3%) died in the intramural hematoma group, whereas 26 patients (16.7%) died in the dissection group (p = 0.011). Histopathologic examination showed no difference in the severity of medial changes, but the site of dissection differed. The thickness of the residual media of the adventitia side was 0.21 +/- 0.12 mm in the intramural hematoma group compared with 0.32 +/- 0.22 mm in the acute aortic dissection group. Dissection was significantly nearer the adventitia in the intramural hematoma group (p = 0.0016). CONCLUSIONS: Dissection is nearer the adventitia in intramural hematoma than in dissection, leading to a greater probability of rupture. These results suggest that operation as soon as possible after the onset of intramural hematoma will contribute to improved survival.

[The validity of the three dimensional model to classify coping behavior].

The purpose of this study was to validate the three dimensional model of classifying coping behavior. The three are: Encounter-Avoidance, Problem-Emotion, Behavior-Cognition Dimension. A set of questionnaires on coping behavior and psychological stress responses were administered, and 1,604 undergraduates and 1,296 adults completed them. Analyses of covariance structure were performed, and results indicated that the three dimensional model, with eight coping style, showed the highest goodness-of-fit statistics. Multiple regression analyses also indicated that Problem-Emotion and Behavior-Cognition dimensions were useful for predicting the coping effects on psychological stress responses. Therefore, the two dimensional model of Problem-Emotion and Behavior-Cognition, with four coping style, would be helpful for further investigation of coping behavior that would buffer psychological stress responses.

Effects of effort and distress coping processes on psychophysiological and psychological stress responses.

The purpose of this study was to investigate the effects of coping processes on psychophysiological and psychological responses in stressful settings. In particular, we focused on the effects of a combination of active and avoidant coping processes. Subjects were 40 healthy undergraduate male students (mean=19.80, S.D.=0.97) who were randomly divided into four groups: (a) an effort coping group in which a subject faced a controllable stressor mobilizing an effortful and active coping behavior for a reward; (b) a distress coping group in which a subject faced a distressful stressor mobilizing an avoidant coping behavior for threat of punishment; (c) an effort-distress coping group in which a subject faced an ambivalent stressor mobilizing active coping behavior for a reward and avoidant coping behavior for threat of punishment; and (d) a control group. Initially, the effects of effort coping, distress coping, and effort-distress coping on psychophysiological and psychological responses were investigated. It was found that effort coping and effort-distress coping intensified cardiovascular responses, particularly blood pressure, and that distress coping and effort-distress coping intensified skin conductance level (SCL). Secondarily, the relationships between effort coping process, distress coping process, psychophysiological responses, and psychological responses were investigated. As a result of cluster analysis, the changes of heart rate and blood pressure were correlated to the change of the effort score, and the changes of SCL and psychological responses were correlated to the change of the distress score. These findings suggest that active coping processes and avoidant coping processes independently affect different response systems.
