This article presents a conceptual framework for individual treatment with chronic anorectic patients. In the first part of the article, the six-stage model for the anorectic process developed over the past years by M. Selvini-Palazzoli and her team is briefly explained. After presenting the model, we then discuss some related concepts, namely, "family game," "rule," and "strategy." Finally, the therapeutic technique in individual treatment is discussed. Two basic assumptions underlie this technique: first, the therapeutic relationship is instrumental, its main purpose being to improve the patient's personal relations outside therapy; second, the focus of the treatment is on the strategic incapacity of the patient who is caught up in and unable to cope with the "concealed family game."  相似文献

The present study demonstrates the safety and effectiveness of an outpatient program designed to respond to adolescent-precipitated crises by mobilizing and restructuring the family's kinship system. Families of 75 adolescents at risk for hospitalization were followed up to 24 months after treatment with Systemic Crisis Intervention. Measures of offspring and family functioning, suicidal behavior, institutional use, and treatment costs are presented. Results clearly demonstrate the safety, effectiveness, and economic viability of Systemic Crisis Intervention.  相似文献

Therapists have a mandate to bring about change, and family therapists appear to have unusual leverage to fullfill such a mandate, that is, to facilitate changes rapidly and effectively. Because and in spite of this mandate, the very notion of change deserves critical reflection. The history of ideas and our clinical experience teach us that changes may be problematic. They may come too fast or too slowly, may endure or fade away, may turn out to be desirable or undesirable, equitable or inequitable, and may, when further consequences and larger systems levels are taken into account, be beneficial or disastrous. This essay examines some of the problematical and contradictory aspects of change and delineates two perspectives on change--systemic optimism and systemic pessimism.  相似文献

This paper combines the results of two studies across different cultures which included an investigation into the relationship between field-dependence-independence and vocational orientations within the framework of Holland's theory of career choice and Witkin's theory of psychological differentiation. The samples included 179 Canadian senior high school students and 376 Pakistani college and university students. Both samples were administered Self-Directed Search and Group Embedded Figures Test. The results indicated a significant relationship between cognitive styles and vocational orientations. It was evident from the findings of these two studies that the theories of Holland and Witkin dove-tail nicely with each other.  相似文献

The relation of the reading interests of Chinese adolescents to their personality (introversion), values (intellectualism and academic achievement), and the reading interests of their family members and peers was studied. A total of 2,114 secondary school students participated in the study. The hypothesized relationship was found to be positive. Specifically, the more introverted students were attracted to more literary materials, whereas the less introverted were fond of more action type of materials. Students high on the value of intellectualism were found to read in general more than those low on the value in almost any kind of materials. Compared to the low ones, students high on the value of academic achievement tended to read more but the differences were not extensive; their interest seemed to focus more on the literary and curriculum-related materials. With respect to family and peer influences, students with parents, siblings, classmates, and friends who read tended to read more and have wider reading interests.  相似文献
