In this study, we examined factors associated with relapse and maintenance following a self-management training course. Thirty-five community professionals participated in a 3-week (30-hr) graduate-level extension course in self-management, which included a self-modification project. Results at a 10-week follow-up showed that end-of-class self-efficacy and outcome expectancy correctly classified over 80% of those who maintained gains in their projects versus those who relapsed. The professionals in the relapsed group also reported significantly more difficulty with anticipated high-risk situations than did those in the maintenance group. 相似文献

Fifteen male and 15 female American therapists-in-training (clinical and counseling psychology graduate students) were asked to take the Minnesota Multiphasic Personality Inventory (MMPI) under each of two instructional sets. In one set, they were instructed to respond to the items as a healthy male would respond, and in the other, as a healthy female would respond. The MMPI profiles obtained from male and female subjects were not significantly different, indicating that these male and female therapists-in-training did not differ in their perceptions of healthy men and women. When the data for male and female subjects were combined, however, healthy women were perceived differently than healthy men on several scales, although the MMPI profiles obtained under both instructional sets were well within normal limits. 相似文献

Comparison of response formats for Multidimensional Health Locus of Control Scales: six levels versus two levels 总被引:1,自引:0,他引:1
Two formats of the Multidimensional Health Locus of Control (MHLC) Scales were administered to 54 college students. Each subject completed the MHLC Scales in the standard 6-level response format (ranging from strongly disagree to strongly agree) and in a revised 2-level format (ranging from disagree to agree). Comparisons of internal consistency measures, principal components, and classification of subjects into groups indicate that the 2-level response format yields comparable data to those obtained with the 6-level format, particularly when classification of subjects is the goal. 相似文献

This study examined the agreement or congruence rate between clinical-discharge diagnoses rendered by a psychiatrist, and admission and discharge MMPI-derived diagnoses from four diagnostic classification systems that have been developed for the MMPI. The four classification systems included a simple high-point code based on the most elevated clinical scale in the profile, the Henrichs revision of the Meehl-Dahlstrom rules, the Goldberg equations, and a system developed by Lachar. Subjects consisted of 150 patients selected from a larger pool of patients who had completed a 9-week adult residential treatment program. Overall, this study yielded modest hit rates between 26% and 34% for MMPI-derived diagnoses and psychiatric diagnoses across the various classification systems. In addition, stability of MMPI-based diagnoses from admission to discharge assessments ranged from 48% to 51% depending on the classification system employed. Findings are discussed in terms of their implications for the use of the MMPI in patient diagnosis. It is recommended that the MMPI be used in conjunction with other sources of clinical and test information in deriving clinical diagnoses. 相似文献

This research tested the hypothesis that children's perceptions of academic competence and their personal control over school-related performance affects subsequent intrinsic interest and preference for challenge in an evaluative setting. In a correlational study, children's self-reported perceptions of academic competence and personal control were found to relate positively to their intrinsic interest in schoolwork and preference for challenging school activities. A subset of this sample was exposed to varying levels of a controlling directive, and preference for challenge was assessed behaviorally during a free-choice period in which subjects were unaware that they were being observed. As predicted, the data indicated that when given the evaluative, controlling directive, children who had high perceptions of academic competence and control preferred a greater challenge than did children whose perceptions were low on these measures. No difference between groups in terms of preference for challenge was evident when no controlling directive was presented. These findings are discussed in terms of theories of intrinsic motivation and potential processes that underly these effects. 相似文献

The relationship of social power to visual displays of dominance between men and women 总被引:2,自引:0,他引:2

Two studies, with undergraduate subjects, investigated how sex and situation-specific power factors relate to visual behavior in mixed-sex interactions. The power variable in Study 1 was expert power, based on differential knowledge. Mixed-sex dyads were formed such that members had complementary areas of expertise. In Study 2, reward power was manipulated. Consistent with expectation states theory, both men and women high in expertise or reward power displayed high visual dominance, defined as the ratio of looking while speaking to looking while listening. Specifically, men and women high in expertise or reward power exhibited equivalent levels of looking while speaking and looking while listening. High visual dominance ratios have been associated with high social power in previous research. Both men and women low in expertise or reward power looked more while listening than while speaking, producing a relatively low visual dominance ratio. In conditions in which men and women did not possess differential expertise or reward power, visual behavior was related to sex. Men displayed visual behavior similar to their patterns in the high expertise and high reward power conditions, whereas women exhibited visual behavior similar to their patterns in the low expertise and low reward power conditions. The results demonstrate how social expectations are reflected in nonverbal power displays. 相似文献
