Effects of daily stress on negative mood 总被引:12,自引:0,他引:12

This article examines the influence of daily stressors on mental health in a community sample. Ss were 166 married couples who completed diaries each day for 6 weeks. In pooled within-person analyses, daily stressors explained up to 20% of the variance in mood. Interpersonal conflicts were by far the most distressing events. Furthermore, when stressors occurred on a series of days, emotional habituation occurred by the second day for almost all events except interpersonal conflicts. Contrary to certain theoretical accounts, multiple stressors on the same day did not exacerbate one another's effects: rather an emotional plateau occurred. Finally on days following a stressful event, mood was better than it would have been if the stressor had not happened. These results reveal the complex emotional effects of daily stressors, and in particular they suggest that future investigations should focus primarily on interpersonal conflicts. 相似文献

We investigated the influence of teacher wait-time and intertrial interval durations on the performance of 4 multiply handicapped students during instruction in 10 skills. Four experimental conditions were evaluated: long wait-time and long intertrial interval, long wait-time and short intertrial interval, short wait-time and long intertrial interval, and short wait-time and short intertrial interval. Instructors attempted to keep short intervals as close as possible to 1 s and long intervals as close as possible to 10 s for both variables. Results showed that student performance was superior under the long wait-time conditions irrespective of the length of the intertrial interval. 相似文献

Burnout prevention for family therapists can be enhanced by careful consideration of the degree of responsibility taken by the therapist contrasted with responsibility placed on the family. Attention to issues of expectations, role definition, sharing of feelings, and therapeutic ambition can ease the strain on the therapist. 相似文献

Exner's Comprehensive Rorschach system is utilized in studying a unique sample of patients--three multiple personalities. Each patient and a number of secondary personalities are tested. Several interpretative and technical aspects of Exner's system are clarified. All of the main personalities are ambient, extending Exner's conclusions regarding the implications of this style. The secondary personalities have personality structures which are remarkably different from those of the main personalities. Differences from previous studies are attributed to unique administrative features of the Comprehensive system. 相似文献

Many counselors are currently undergoing a Kuhnian paradigm shift from linear models of behavioral problem conceptualization to systemic conceptual models. As a result, it has become incumbent on counselor-educators to introduce the systems concept of family therapy to their students within a framework that renders it meaningful not only intellectually but also practically. This paper presents one way of doing this successfully with master's level counselors-in-training who have no live families on which to practice. An overview of systems approaches to family therapy is presented along with a seven-stage supervision approach for teaching structural/strategic therapy in limited situations where the supervision of live families is not practical or possible. 相似文献

Test-retest stability of the Kaufman Assessment Battery for Children (K-ABC) was investigated over a 5-month interval for 42 Mexican-American preschool/kindergarten children. The results indicated that the stability coefficients for K-ABC Global scales and subtests were generally of adequate magnitudes (e.g., .70s and .80s), providing some evidence that the K-ABC is a relatively stable instrument for the sample. The results are discussed in the context of a test-retest study reported in the K-ABC Manual. Global scale stability coefficients were found to range from .76 to .90, and for the subtests the coefficients ranged from .26 to .89. The patterns of gain scores were very similar to the patterns reported in the stability investigation in the K-ABC Manual. 相似文献

This essay provides guidelines for designing a doctoral program in behavior analysis. First, we propose a general accomplishment for all behavior analytic doctoral students: that they be able to solve problems concerning individual behavior within a range of environments. Second, in order to achieve this goal, we propose that students be trained in conceptual and experimental analysis of behavior, the application of behavioral principles and the administration of behavioral programs. This training should include class work, but it should emphasize the immersion of students in a variety of environments in which they are required to use behavior analytic strategies. Third, we provide an example of a hypothetical graduate program that involves the proposed training. Finally, an evaluation plan is suggested for determining whether a training program is in fact producing students who are generalized problem-solvers. At each step, we justify our point of view from a perspective that combines principles from behavior analysis and educational systems design. 相似文献
