Use of approximate weights would greatly simplify decision analysis under certainty since detailed weight elicitation could be avoided. This paper examines the degree to which rank order information about weights can be used to identify a best alternative, or falling uniqueness prescribes an easily implemented rule for selecting a ‘best’ alternative. The prescribed rule uses as weights the centroid of the feasible region defined by the rank order information. In conjunction with the rule, the value of the rank order information can be determined using an ‘expected gain from weight precision’ (EGWP) measure, analogous to ‘expected value of perfect information’ in decision analysis under uncertainty.  相似文献

The main issue of this paper concerns the mediating role of risk appraisal in the relation between past and future behavior. We expected previous risky behavior to heighten risk appraisal, which, in turn, should stimulate preventive behavior. Results ofthree tests of this mediation hypothesis showed that past behavior was strongly related to future behavior; people who behaved hazardously in the past indicated that they tend to do so in the future. Generally, the expected relation between past behavior and risk appraisal was supported. More risky behavior in the past was associated with a heightened risk appraisal. Results also indicate a relation between risk appraisal and future behavior, but in the opposite direction as predicted. Heightened risk appraisal was related to increased levels of risk in future behavior. When predicting future behavior by both risk appraisal and past behavior the effect of risk appraisal on future behavior disappeared, while past behavior remained a strong predictor of future behavior. In a few cases risk appraisal still predicted future behavior when past behavior was controlled for. Unfortunately, these cases showed the opposite relation; i.e., heightened risk appraisal was related to more risky future behavior. Implications of these findings for research on the role of risk appraisal will be discussed.  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

Money may be the most upsetting and therefore the most avoided topic in group psychotherapy. To overcome this resistance, the leader must secure prospective members' willingness to speak openly about financial matters. Financial issues particular to group therapy emerge when money is normalized as a topic for discussion. These include lowering or not raising fees, rescheduling, leaves of absence, combined and conjoint therapy, and nonverbal behaviors. Several case examples are provided. Members' strong feelings toward the leader around financial transactions often find expression in angry accusations. Suggestions for dealing therapeutically with countertransference reactions to these accusations are offered.  相似文献

The author provides an overview of critical factors in the working phase of group psychotherapy from the perspective of psychodynamic theory. The discussion is organized around a clinical vignette to illustrate various types of intervention such as past, here and now, future; individual, interpersonal, group as a whole; in group--out of group; affect-cognition; and understanding--corrective emotional experience. The critical "windows into the unconscious," transference, counter-transference, and free association, are also discussed in terms of the clinical example. The author concludes his article with a few thoughts about the future of psychodynamic theory in relationship to group treatments.  相似文献

Eighty-two women, presenting as normal-weight bulimics, obese binge eaters, social phobics, and individuals with panic disorder, were compared on anxiety, depression, and substance abuse. All were administered the Anxiety Disorder Interview Schedule-Revised and completed the Michigan Alcohol Screening Test, Drug Abuse Screening Test, and Self-Consciousness Scale. A striking proportion of eating disorder subjects were comorbid for one or more anxiety disorders, the most frequent diagnoses being generalized anxiety disorder and social phobia. The results suggest that the place of anxiety in bulimia nervosa goes beyond that discussed within the context of the anxiety reduction model. Conflicting comorbidity findings among this and prior investigations are noted, however, and discussed in terms of the issue of differential diagnosis between eating and anxiety disorders.  相似文献

A 5-year longitudinal study investigated the interrelationships among children's experiences of depressive symptoms, negative life events, explanatory style, and helplessness behaviors in social and achievement situations. The results revealed that early in childhood, negative events, but not explanatory style, predicted depressive symptoms; later in childhood, a pessimistic explanatory style emerged as a significant predictor of depressive symptoms, alone and in conjunction with negative events. When children suffered periods of depression, their explanatory styles not only deteriorated but remained pessimistic even after their depression subsided, presumably putting them at risk for future episodes of depression. Some children seem repeatedly prone to depressive symptoms over periods of at least 2 years. Depressed children consistently showed helpless behaviors in social and achievement settings.  相似文献

This article examines and clarifies controversies about the concept of illness in the field of family therapy. We contend that illness, as traditionally understood in all cultures, is a relational, transactional concept that is highly congruent with core principles of present-day family theories. Family therapists need not buy into a biotechnical, reductionistic reframing of illness as disease. Rather, it is more appropriate to conceptualize and work with illness as a narrative placed in a biopsychosocial context. Such a narrative includes how shared responsibility for coping and for finding solutions can take place, without becoming involved in disputes about causal models.  相似文献
