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

In this archival study the authors sought to determine the relationship, if any, between counseling outcomes and the topical focus in career counseling. Twenty-two counselors saw 46 adult clients at a community-based clinic for an average of eight sessions. Counseling outcome and topical focus (the extent to which the actual content of counseling sessions reflected relatively more vocationally or personally focused topics) were assessed from follow-up questionnaires to former career clients and from trained raters' evaluations of the counselors' written progress notes. Results showed that, from the counselors' perspective, outcomes were better when the focus of the sessions was relatively more vocational than personal and when relatively more interviews were held. Client satisfaction, on the other hand, was predictable only from the counselor's level of experience. Satisfaction with occupational status was not associated with any of the client, counselor, or treatment factors. Discussion focuses on the contribution of the results to career counseling practice and on the feasibility and validity of retrospective, archival research.  相似文献

This study examines the relationship between performance on a context-independent fault diagnosis task and two dimensions of cognitive style: field dependence/independence (D-I) and focusing/scanning (F-S). The effects on diagnosis performance of training and the ability of both dimensions of style jointly to predict fault-finding ability were considered. The results showed that field independents and focusers were superior fault diagnosticians. Training, in the form of verbal feedback messages, was uniformly effective for the D-I dimension although field independents maintained a superior level of performance, over field dependents. In general, for the F-S dimension, training had little effect on either the focusers or scanners. A combination of scores on the F-S and D-I dimensions significantly enhanced the proportion of the variance in testing efficiency that could be accounted for during fault-finding. Finally it is argued that the F-S and D-I dimensions should be recognized as measures of ability, not style. Future research should be directed at identifying between subject differences on fault diagnosis tasks with reference to theories of information processing.  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

In this paper, I discuss a number of issues concerning software selection in instructional laboratories. First, I describe several taxonomies of instructional software and argue that the most important dimension of instructional software is that it must be an efficient tool. Second, I discuss some elements of the context of the instructional lab, including sophistication of users. Third, I explore design features, especially those related to ease of learning to use packages. Several other issues are also considered, such as where to find software reviews.  相似文献

This article presents a simulation-based tutorial system for exploring parallel distributed processing (PDP) models of information processing. The system consists of software and an accompanying handbook. The intent of the package is to make the ideas underlying PDP accessible and to disseminate some of the main simulation programs that we have developed. This article presents excerpts from the handbook that describe the approach taken, the organization of the handbook, and the software that comes with it. An example is given that illustrates the approach we have taken to teaching PDP, which involves presentation of relevant mathematical background, together with tutorial exercises that make use of the simulation programs.  相似文献
