This article reports the development of a scale for evaluating family therapist skills. The scale includes ten items within each of five skill categories. All items were found to discriminate significantly between videotaped segments of effective and ineffective family therapist skills. Also all skill categories discriminated significantly between experienced and inexperienced family therapists. The interrater reliability and internal consistency of the categories were also judged to be acceptable. Suggestions are presented for uses of the scale in therapist training research. 相似文献

Participatory research (PR) is a method of social investigation, an educational process and a process of collective action.
Few examples of PR in the urban United States currently exist. Church-based community organizing’s process of systematically
identifying values and concerns as a way of building relationships based on personal and social knowledge is fundamentally
similar to the key characteristics of PR. Two examples of church-based organizing in inner city Chicago neighborhoods are
the Northwest Community Organization and the Pilsen resurrection Project. Identification of such church-based organizing efforts
as PR may help identify additional urban United States examples of PR, but also raises questions as to the role of the academic
and the practical value of PR for community groups. 相似文献

Trade-offs between traits such as fecundity or survival are fundamental to much of our understanding of the evolution of life histories. There has been much renewed interest and controversy concerning methods for estimating trade-offs, in the wild or in captivity, and with or without experimental manipulations. In this paper, we assess the general question of the utility of modern capture-recapture methods as a robust tool for estimating trade-offs in natural populations. We present results from analyses of two forms of trade-offs: the cost of present reproduction on future survival and the cost of present reproduction on the probability of breeding in the future. We apply the methods to data from a long-term study of a snow goose population, and generally discuss the advantages and potential problems with various approaches. 相似文献

A test is proposed which requires a better fit in the extremes of a distribution than the Kolmogorov-Smirnov test for H0. not to be rejected. Critical values are calculated for sample sizes up to 100, and approximate critical values are found for larger samples. The power of the test is obtained for a number of distributions, and it is shown that the test is more powerful than some existing tests for a wide range of cases 相似文献
