We set up a mutual help network among the elderly residents of a government-subsidized apartment building and evaluated its impact on their social ties, social support satisfaction, and depression. A quasi-experimental design was used, with the residents of a similar building located in the same neighborhood serving as the control group. A total of 230 individual services were exchanged, and 28 group activities were organized during the study period. There was almost no difference between experimental and control groups with respect to the change over the study period in the number of social ties with other residents of the building. Support satisfaction decreased in both groups, but the decrease was larger in the experimental group. The control group had a slight decrease in the frequency of their depressive symptoms, whereas the experimental group had a moderate increase. More research is needed on the ability of social support interventions to produce beneficial effects on mental health among individuals who are not experiencing a particular life stress. 相似文献

Differences in reproduction as well as in behavior in the presence of females were evaluated according to dominant and subordinate male rank in albino mice, in the temporary absence of each male's antagonist. Dominant males reproduced more successfully than subordinate males. Subordinate males were generally inactive, except for displacement activities, during the first 15 min they were exposed to female partners. These findings suggest that mechanisms other than male-male interference or mating order may be operating or influencing behavior and reproductive results. 相似文献

Although stress and anxiety have long been assumed to play an exacerbatory role in asthma, no study has systematically documented that daily exacerbations of asthma symptoms are related to stress and/or anxiety. In this study, 24 airways obstruction patients (12 asthmatics and 12 chronic obstructive pulmonary disease patients) were instructed to monitor the severity of daily respiratory symptoms. In addition, subjects recorded their daily anxiety level and the number and perceived impact of daily stressors. The results showed that although there were differences between high- and low-stress days for both groups, there were no differences between groups on symptom severity or between high- and low-anxiety days, as measured by the State-Trait Anxiety Inventory (STAI). Thus, although the number and impact of daily stressors were found to be directly associated with the severity of asthma symptoms, anxiety does not appear to have a direct role in the exacerbation of asthma. The findings failed to support the anxiety theory of asthma but provided an explanation for the poor results obtained in previous treatment studies which employed anxiety management with asthmatics. 相似文献

A recent clinical study of outpatient psychotherapy groups in a community mental health center explored the linkage between group leadership variables, group climate, and outcome. The study involved nine outpatient therapy groups, over 50 group clients, and several group therapists. A repeated measures design involving assessment of clients' outcome and level of functioning, group leadership style, and group climate was used to assess changes over a 6-month period. The findings suggest: 1) a reduction in symptoms and improved functioning for clients; 2) a similarity of perceptions by members and leaders of perceived leadership behaviors and group climate; 3) the presence of direct and indirect influences of group climate and leadership behavior on clients' outcome; and 4) a linkage between leadership behavior and group climate with the theoretical orientation of the group. The findings of the research are discussed in relation to the understanding of specific effects in group psychotherapy and the implications for construction of group psychotherapy theory.The authors would like to thank Robert Dies, Ph.D., for his helpful suggestions in the early phase of this study; Roy MacKenzie, M.D., for permission to use the Group Climate Questionnaire; Diane DePalma, Ph.D., for permission to use the Global Leadership Behavior Index; Chris Boltwood, B.A., for her untiring efforts in administering the instruments and coding and entering the data; and most importantly, the psychotherapy group members and the group therapists for their cooperation in this endeavor—without their help, this clinical study would not have been possible.A version of this paper was presented at the Annual Meeting of the American Group Psychotherapy Association, 1987, New Orleans, Louisiana. Lenore Phipps, R.N., M.S., C.S., was formerly Director, Group Psychotherapy Program at Park Ridge Mental Health Center, Rochester, now in private practice at Guild Medical Center, Norwood, MA 02062. 相似文献

Counseling training programs have failed to differentiate between and among behavioral, cognitive, and unconsciousness dimesnsions. This omission has resulted in confusion and competition in many counseling curricula in that valuable programs are competing for space rather than being integrated systematically. This article proposes a multilevel model of intentionality which integrates the several aspects of the counselor-client relationship. In turn, this integration of behavioral, cognitive, and unconscious dimensions will have important applications in counselor daily practice. 相似文献

Analysis of the unconscious ego resistances is one of those clinical concepts more honored in the breach than in the observance. This same point has been made periodically over the past fifty years. It has not been sufficiently realized that a true psychoanalytic understanding of resistance analysis could only begin with Freud's second theory of anxiety. Freud himself never fully embraced this theory, and clinical contributions since then have varied in their ability to use the techniques inherent in the second theory of anxiety. Recent contributions to the literature have not eliminated the espousal of theories of resistance based on earlier views of anxiety. Reasons cited for this include: the ambiguities in Freud's writing, the direction of the early ego theorists, and proclivities toward deeper interpretations. 相似文献

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
