This article reviews the development of a new measure to assess children's perceptions of intergenerational boundary violations in families. The Boundary Violations Scale is a theoretically derived instrument consisting of 12 items. Principal components analysis using data from 119 young adolescents from diverse ethnic backgrounds (i.e., 56% Hispanic and 44% non-Hispanic) revealed three factors (promoting maturity, forming coalitions, and communicating as peers) that are consistent with the behavioral manifestations of this construct as posited by structural family theory. The validity of the measure was supported by significant correlations with theoretically relevant measures of family processes and child adjustment as reported by children and their mothers.  相似文献

This study of the reliability of three new tests of work performance considered the effect of test reactivity on measured performance. The tests are components of an employment screening battery designed for placement of applicants in automotive assembly jobs. Statistical measures of reliability were compared with a simple measure of test reactivity in a sample of 51 healthy adults. The effect of test reactivity on employment selection decisions using various cut scores was studied. Test reactivity is found to be a significant threat to reliability that must be considered when skill-based performance tests are used on a serial basis. When intended for use on a serial basis, such tests should be studied for both reliability and reactivity. In addition to reporting traditional statistical indices of reliability, an index of the reactivity should be reported.  相似文献

Performance Assessment (PA) is the use of mathematical models to simulate the long-term behavior of engineered and geologic barriers in a nuclear waste repository; methods of uncertainty analysis are used to assess effects of parametric and conceptual uncertainties associated with the model system upon the uncertainty in outcomes of the simulation. PA is required by the U.S. Environmental Protection Agency as part of its certification process for geologic repositories for nuclear waste. This paper is a dialogue to explore the value and limitations of PA. Two skeptics acknowledge the utility of PA in organizing the scientific investigations that are necessary for confident siting and licensing of a repository; however, they maintain that the PA process, at least as it is currently implemented, is an essentially unscientific process with shortcomings that may provide results of limited use in evaluating actual effects on public health and safety. Conceptual uncertainties in a PA analysis can be so great that results can be confidently applied only over short time ranges, the antithesis of the purpose behind long-term, geologic disposal. Two proponents of PA agree that performance assessment is unscientific, but only in the sense that PA is an engineering analysis that uses existing scientific knowledge to support public policy decisions, rather than an investigation intended to increase fundamental knowledge of nature; PA has different goals and constraints than a typical scientific study. The proponents describe an ideal, six-step process for conducting generalized PA, here called probabilistic systems analysis (PSA); they note that virtually all scientific content of a PA is introduced during the model-building steps of a PSA; they contend that a PA based on simple but scientifically acceptable mathematical models can provide useful and objective input to regulatory decision makers. The value of the results of any PA must lie between these two views and will depend on the level of knowledge of the site, the degree to which models capture actual physical and chemical processes, the time over which extrapolations are made, and the proper evaluation of health risks attending implementation of the repository. The challenge is in evaluating whether the quality of the PA matches the needs of decision makers charged with protecting the health and safety of the public.  相似文献

Family therapists criticise the ‘medical model’ for relying on linear causality, focusing on pathology rather than health processes and tending to coerce the family into preconceived models. These criticisms might be legitimately levelled at 19th Century models but not at modern medical models which include the circularity of general systems theory, attention to ecological field, and understanding of reciprocal influences of many factors such as emotions, antibodies, genetic endowment, nutrition, interpersonal relations, environmental stress, and symbiotic micro-organisms. This modernised medical model is consistent with modern family therapy theory which integrates general systems theory, ecological theory, communication theory, small group process, role theory and metaphoric communications. Family therapy purists define themselves by contrasting their differences with ‘the medical model’. Eclecticists tend to be practitioners who use broad theoretical frames of reference and commonsense, straight-forward, direct intervention where it is likely to work but will resort to indirect, metaphoric or paradoxical intervention for the more complex and resistant family.  相似文献

The present study examined the effectiveness of Project PRIDE, a school-based, counselor-administered, drug and alcohol prevention program. The study is presented in the context of Project PRIDE'S efforts to keep itself current and effective via continual evaluation-based development. In this outcome evaluation, Project PRIDE participants demonstrated greater pretest to posttest gains on five of six outcome measures compared to control students, although many of the changes were small or moderate and only two were statistically significant. Further, as predicted, gains in more factual or objective areas of the program were greater than in more subjective areas dealing with student perceptions and feelings. The limitations and implications of the findings are discussed. Also discussed are the advantages of the Binomial Effect Size Display as a data presentation mode that promotes both client and general audience understanding of results.  相似文献

The present paper describes a naturalistic study of therapy with children in foster care. The goal was to attempt to begin to understand what happens to children in foster care while they are in therapy. The functioning of all children referred for therapy in a foster care agency was assessed as rated by different informants at different points in time over an 18-month period. These children present with low-level behavior problems but the level and type of problem they present with depends on the person rating the child and the child’s gender and age. Two thirds of the children improve and do so within the early stages of therapy. One third of the children do not improve. The distinguishing feature of this group appears to be the high level of aggressive behaviors reported at intake. Results suggest that improvement depends on the eye of the beholder. These findings are discussed and recommendations for therapeutic and systemic practice are made. The importance of using multiple informants when evaluating the treatment needs of children in care is pointed out as is the need to rethink therapeutic strategies with children that present with high levels of aggressive behavior at intake and show no improvement after the first 6 months of therapy.  相似文献

Social movement theories provide a framework for explaining the post-1990 rise in China’s citizen-organized environmental nongovernmental organizations (ENGOs), which consisted of at least 128 organizations as of 2004. We use a political process model, which is based on favorable political opportunities, cognitive liberation, and indigenous organizational strength, to explain the sharp growth in citizen organized ENGOs. In addition, we employ a world society perspective to help clarify why the political environment in China became favorable for ENGO growth, and how international ENGO practices were diffused within China. Our analysis shows that the relatively high status of ENGO founders together with their personal and professional networks also played important roles in ENGO growth.
