This study examined several propositions of social cognitive career theory ( [Lent et al., 1994] and [Lent et al., 2000]) with a sample of 393 Mexican American college students. It was hypothesized that person input (i.e., age) and background contextual variables (i.e., Anglo orientation, Mexican orientation, familism, instrumentality, and expressivity) would predict career self-efficacy across Holland’s (1997) six RIASEC types. In addition, we examined the proposed relations between career self-efficacy, career interests, and career choice goal across the six RIASEC areas. Our results indicated that (a) Artistic, Social, Enterprising, and Conventional career models were similar across gender and university affiliation groups, (b) gender differences were found in the Realistic career model, (c) institutional affiliation differences were found in the Investigative career model, and (d) the models were a good fit to the data. Implications for future vocational research and career interventions are discussed.  相似文献

Two different self-help training programs (multimodal cognitive-behavioral training (CBT) and applied relaxation (AR)) presented via the Internet were compared with an educational intervention (EDU) in an RCT. Sixty-five children and adolescents (mean age: 12.7 years) with recurrent headache (at least 2 attacks per month) were each assigned to one of the three treatment conditions. The main outcome variables related to changes in headache frequency, intensity and duration as well as the responder rate (50% reduction of headache frequency) and NNTs. Secondary outcome variables were pain catastrophizing and general well-being (depression, psychopathological symptoms and health-related quality of life). All groups showed significant reduction in headache frequency, duration and pain catastrophizing, but not in headache intensity, depression, psychopathological symptoms or health-related quality of life at post-assessment. NNTs were 2.0 for the comparison CBT and EDU; 5.2 for the comparison of AR and EDU at post-treatment. The highest responder rates at post were from CBT (63%), significantly different compared to AR (32%) and EDU (19%), whereas at follow-up no significant differences were found (CBT: 63%, AR: 56%, EDU: 55%) reflecting in the NNTs.The effects remain stable in headache frequency, pain catastrophizing and psychopathological symptoms across all groups at follow-up assessment. CBT showed the highest within-effect size in headache frequency, duration and pain catastrophizing. The results support the use of Internet programs for pediatric recurrent headache, especially given their accessibility and suitability for children and adolescents. Further studies are needed to improve their quality and efficacy.  相似文献

This study examined the construct‐related validity of an assessment centre (AC) developed by a national distribution company for the selection and development of lower‐grade managers. In five locations throughout Britain, 487 individuals were observed on nine dimensions, each of which was measured through six distinct exercises. Multitrait‐multimethod analyses conducted to investigate the convergent and discriminant validity of the AC revealed strong exercise (“method”) effects. This finding was corroborated by an exploratory factor analysis showing that AC ratings clustered into factors according to exercises, rather than according to performance dimensions. A series of MANOVAs and chi‐squared tests demonstrated that neither the exercise ratings nor the selection decision were biased by sex, ethnicity, or training location, and a logistic regression determined which exercises had most impact on the final decision.  相似文献

In psychoanalytic writing an oversimplified interpretation of Freud's concept of the life and death instincts sometimes colours the presentation. Roughly, there is an implication that the life instinct is 'good' and the death instinct 'bad'. Freud however is clear that: "Neither of these instincts is any less essential than the other; the phenomena of life arise from the concurrent or mutually opposing action of both"(1933b, p. 209). In this paper I look in detail at the characteristics of the life instinct as conceptualized by Freud, and draw on Bion's work 'on linking' to elaborate Freud's view that binding is the life instinct's key characteristic. I suggest that there are pathological forms of both the life and death instinct if defused (separated off) from the other, and I explore a pathological variation of the life instinct in which binding is without the negation, rest, limit or end provided by the 'opposing action' of the death instinct. I consider an instance of the kind that any analyst might meet clinically, in which an inhibited patient experiences severe anxiety that life-giving connections threaten to proliferate indiscriminately and to an overwhelming intensity and size.  相似文献

Abstract: This essay interprets and responds to Richard Kearney's metaphysics of possibility and hermeneutics of religion against the background of Nietzsche's proclamation of the death of God and the theodicy problem. Kearney's work is thus read as an interesting but ultimately problematic attempt to preserve or perhaps reinstate religious thought after the modern critique of idols. In addition, his positions are compared and contrasted with some of authors with whom he seems to be in limited agreement (for example, Plotinus, Hillesum) as well as some with whom he clearly breaks (for example, Girard, Sölle).  相似文献

Facilitation of Extinction of Conditioned Fear by D-Cycloserine   总被引:1,自引:0,他引:1  
Abstract— Excessive fear and anxiety are characteristic of disorders such as post-traumatic stress disorder (PTSD) and phobias and are believed to reflect abnormalities in neural systems governing the development and reduction of conditioned fear. Conditioned fear can be suppressed through a process known as extinction, in which repeated exposure to a feared stimulus in the absence of an aversive event leads to a gradual reduction in the fear response to that stimulus. Like conditioned fear learning, extinction is dependent on a particular protein (the N-methyl-D-aspartate or NMDA receptor) in a part of the brain called the amygdala. Blockade of this receptor blocks extinction and improving the activity of this receptor with a drug called D-cycloserine speeds up extinction in rats. Because exposure-based psychotherapy for fear disorders in humans resembles extinction in several respects, we investigated whether D-cycloserine might facilitate the loss of fear in human patients. Consistent with findings from the animal laboratory, patients receiving D-cycloserine benefited more from exposure-based psychotherapy than did placebo-treated controls. Although very preliminary, these data provide initial support for the use of cognitive enhancers in psychotherapy and demonstrate that preclinical studies in rodents can have direct benefits to humans.  相似文献

The purpose of the broader project on which this report is based was to utilize a Practice Research Network, an alternative to traditional clinical studies to 1) identify demographically one practice group, namely professional counselors in the United States, 2) describe their practice patterns, and 3) identify their client population and the efficacy of their clinical work through client outcomes based on actual client reports. This article describes the development of one such nation‐wide Practice Research Network (PRN) and provides some preliminary findings for each phase of the project. Use of the PRN model can help overcome the traditional “research to practice” gap and provide research results into community practice thus integrating outcomes measures into the daily practice of mental health professionals. During the early phases of this project, a software program was developed upon which the participating practitioners could identify the data elements within the parameters of the focus on their agreed‐upon research interests, enter data following client visits over time, and by comparing their own composite profiles and effectiveness with those of other participating practitioners who had clients presenting with similar diagnoses, could alter their own service delivery patterns, therapeutic interventions, or approaches while working with the clients and thereby improve the efficacy of their service. By participating, the practitioners benefited by access to downloadable and printable reports on profiles of 1) their specific clients, 2) their service delivery patterns, and 3) the outcomes or efficacy by their clients’ direct feedback. They were also able to compare these results with the composite data from other practitioners.  相似文献
