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

A consecutive sample of mid- and late-life bereaved spouses were randomly assigned to treatment and no-treatment groups. Two hypotheses were tested: (1) that brief group psychotherapy during the early stages of loss would facilitate adjustment assessed by measures of mental health, positive psychological states, social role, and mourning; and (2) that positive effects would be maximized for subjects who were more distressed psychologically. Although group participants, compared with untreated controls, did over 1 year show modest improvement on role functioning and positive psychological states, overall the study failed to find substantial support for the two major hypotheses. Both experimental and control groups showed improvement over the year, particularly on measures of mental health and mourning. Differential benefit was not observed for the high-risk group. 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

The effects of reinforcement schedules on rats' choice behavior in extinction were studied. In a free-operant chamber equipped with two retractable bars, the experimental animals were trained to press the bars separately for a food reward. One bar delivered the reward on a continuous reinforcement (CRF) schedule, and the other delivered the reward on a partial reinforcement (PRF) schedule. Control animals earned the reward from both bars with the same reinforcement schedule, either a CRF or a PRF. When both bars were simultaneously available during extinction, the experimental animals responded more frequently to the CRF than to the PRF alternative, demonstrating a reversed within-subjects partial reinforcement extinction effect (PREE). A conventional between-subjects PREE was replicated in the control subjects. The results of this study were inconsistent with both Amsel's (1962, 1967) frustration hypothesis and Capaldi's (1966, 1967) sequential hypotheses. 相似文献

In this study, the authors assessed the relation of parental reinforcement and parental values to young children's prosocial behaviors. Parents' dyadic interactions with their 1- to 2-year-old children were videotaped in the home on two occasions approximately 6 months apart. The children also were videotaped playing with a peer at 3 1/2 to 4 1/2 years of age. Parental reinforcement of the children's prosocial behaviors was coded, as were the children's prosocial behaviors with the peer. The frequency of girls' spontaneous prosocial behaviors decreased in the early years; modest consistency was observed for boys (but not girls) across the two parental sessions. No relation existed between the frequency of children's prosocial behaviors with their parents and their behaviors with peers. Both maternal and paternal valuing of compliance were negatively related to the mothers' use of reinforcement for children's spontaneous prosocial behaviors. Parental reinforcement of compliant prosocial behaviors was negatively related to children's compliance with a peer's request for prosocial behavior and positively related to defensive behavior with the peer. Fathers' valuing of prosocial behavior was associated with children's compliance with the peer's requests for prosocial action. Parents who valued compliance had children who exhibited low levels of compliant prosocial behaviors with the peer, possibly because of the depressed level of peer interaction. 相似文献

Researchers concluded that Item 2 of the Short-form General Health Survey of the Medical Outcomes Study can be used as a single-item measure of health-related quality of life. This conclusion is tested again on a random sample of elderly people in the Netherlands. Although it can be concluded that the psychometric properties of the short form are satisfactory, the use of the single item as a measure of health-related quality of life is discussed. 相似文献

This study explored the relationship between individual strategies of coping and blood pressure responses during and after mental stress. Blood pressure behavior was measured noninvasively and continuously before, during and after a mental stress situation in 27 normotensive subjects. Coping strategies were assessed with the Stressverarbeitungsfragebogen (SVF; coping with stress inventory). Two extreme groups were formed on the basis of the scores in the SVF. Results were: (a) Individuals who used coping strategies characterized by controlling the situation directly and constructively, in contrast to probands not using these strategies, exhibited lower blood pressure during the stress situation and a faster return to baseline levels after cessation of stress. (b) Subjects using a coping behavior characterized by the use of defense mechanisms such as suppression and denial, also showed lower blood pressure during stress but a significantly delayed return to baseline levels of blood pressure after stress was concluded. 相似文献
