For the balanced variance component model when the intraclass correlation coefficient is of interest, Bayesian analysis is often appropriate. Berger and Bernardo’s (1992a) grouped ordering reference prior approach is used to analyze this model. The reference priors are developed and compared for the posterior inference with real and simulated data. We examine whether the reference priors satisfy the probability-matching criterion. Further, the reference prior is shown to be good in the sense of correct frequentist coverage probability of the posterior quantile.  相似文献

Abstract

Objective: To implement a pilot quality improvement project for depression identification and treatment in college health. Participants: Eight college health center teams composed primarily of primary care and counseling service directors and clinicians. Methods: Chronic (Collaborative) Care Model (CCM) used with standardized screening to identify, treat, and track depressed students for 12 weeks to monitor predetermined process and clinical outcomes. Results: Of all students receiving primary medical care services between January 2007 and May 2008, 69% (n = 71,908) were screened for depression. A total of 801 depressed students were treated and tracked; most predetermined treatment process and clinical outcome targets were achieved. Conclusion: The CCM for depression shows promise for improving depression identification and care for college students.  相似文献

Abstract

Objective: The investigators examined the health and well-being correlates of hearing the popular phrase “that's so gay” among gay, lesbian, and bisexual (GLB) emerging adults. Participants: Participants were 114 self-identified GLB students aged 18 to 25 years. Methods: An online survey was distributed to students at a large public university in the Midwest during winter 2009. Results: Participants’ social and physical well-being was negatively associated with hearing this phrase, specifically feeling isolated and experiencing physical health symptoms (ie, headaches, poor appetite, or eating problems). Conclusions: College professionals and student leaders must acknowledge that the phrase is a form of heterosexist harassment. As such, policies addressing diversity and harassment should address students’ use of this phrase, aiming to reduce its use. Additionally, colleges and universities should develop practices that counteract poorer well-being associated with hearing the phrase.  相似文献

All adoptions, including those facilitated by public agencies, should be evaluated for openness. Although there are no national figures related to openness in public welfare, there are indications that it is not considered in all cases. Adoption myths may be one of the reasons that adoption workers do not always assess a family's ability to maintain a more open adoption arrangement. The following study is the initial validation of a multidimensional psychometric instrument developed to measure myths as they relate to open adoption. Based on a sample of 547 university students, the results indicate very good reliability and acceptable factorial and construct validity. The instrument was designed as a training and research tool to inform child welfare personnel and policy makers of the influence of adoption-related myths on child welfare adoption practice.  相似文献

The analysis of survival endpoints subject to right-censoring is an important research area in statistics, particularly among econometricians and biostatisticians. The two most popular semiparametric models are the proportional hazards model and the accelerated failure time (AFT) model. Rank-based estimation in the AFT model is computationally challenging due to optimization of a non-smooth loss function. Previous work has shown that rank-based estimators may be written as solutions to linear programming (LP) problems. However, the size of the LP problem is O(n 2+p) subject to n 2 linear constraints, where n denotes sample size and p denotes the dimension of parameters. As n and/or p increases, the feasibility of such solution in practice becomes questionable. Among data mining and statistical learning enthusiasts, there is interest in extending ordinary regression coefficient estimators for low-dimensions into high-dimensional data mining tools through regularization. Applying this recipe to rank-based coefficient estimators leads to formidable optimization problems which may be avoided through smooth approximations to non-smooth functions. We review smooth approximations and quasi-Newton methods for rank-based estimation in AFT models. The computational cost of our method is substantially smaller than the corresponding LP problem and can be applied to small- or large-scale problems similarly. The algorithm described here allows one to couple rank-based estimation for censored data with virtually any regularization and is exemplified through four case studies.  相似文献

A developmental approach to resistance   总被引:1,自引:1,他引:0  
Diagnosis, treatment and technical interventions are dependent on a theoretical interpretation of the behavior of a patient. The clinical material presented addresses an initial alternative assessment of resistances, not from a classical theoretical position of opposition to the analytic procedure, the defense of the neurosis and a safeguard against pain and danger, but behavior that expresses a developmental need and deficit in the patient that is expressed in the treatment and relationship to the therapist.  相似文献

Winnicott suggested that delusions are a failed form of play. Using Winnicott's theories of the play space, this paper illustrates through clinical material how the therapist can join a delusion and convert it into an area of play. Discussion includes an analysis of the use of play in working with the transference and countertransference as well as the therapist's resistances to engaging in play.  相似文献
