Blending high-quality and rigorous research with pure evaluation practice can often be best accomplished through thoughtful collaboration. The evaluation of a high school drug prevention program (All Stars Senior) is an example of how perceived competing purposes and methodologies can coexist to investigate formative and summative outcome variables that can be used for program improvement. Throughout this project there were many examples of client learning from evaluator and evaluator learning from client. This article presents convincing evidence that collaborative evaluation can improve the design, implementation, and findings of the randomized control trial. Throughout this paper, we discuss many examples of good science, good evaluation, and other practical benefits of practicing collaborative evaluation. Ultimately, the authors created the term pre-formative evaluation to describe the period prior to data collection and before program implementation, when collaborative evaluation can inform program improvement. 相似文献

Family therapy for drug abuse: review and updates 2003-2010 总被引:1,自引:0,他引:1
Rowe CL 《Journal of marital and family therapy》2012,38(1):59-81
Just 15 years ago, Liddle and Dakof (Journal of Marital and Family Therapy, 1995; 21, 511) concluded, based on the available evidence, that family therapy represented a "promising, but not definitive" approach for the treatment of drug problems among adolescents and adults. Seven years later, Rowe and Liddle (2003) review described considerable progress in this specialty with encouraging findings on adolescent-focused models based on rigorous methodology, as well as advances with adult-focused family-based treatments. The current review brings the field up to date with highlights from research conducted in the intervening 7 years, cross-cutting issues, recommendations for new research, and practice implications of these findings. Adolescent-focused family-based models that attend to the ecology of the teen and family show the most consistent and strongest findings in recent studies. Adult-focused models based on behavioral and systems theories of change also show strong effects with drug abusers and their families. The overarching conclusion is that family-based models are not only a viable treatment alternative for the treatment of drug abuse, but are now consistently recognized among the most effective approaches for treating both adults and adolescents with drug problems. 相似文献

Intervention research for couples and families managing chronic health problems is in an early developmental stage. We reviewed randomized clinical trials of family interventions for common neurological diseases, cardiovascular diseases, cancer, and diabetes, which is similar to the content of previous reviews discussed later. One overriding theme of these studies is that patients with chronic illnesses and their families face a variety of challenges to which researchers have responded with an array of treatment modalities. Very few of the interventions reviewed, with the exception of treatment for adolescents with diabetes, tested family psychotherapy models. Most interventions were time-limited therapeutic interventions that trained families to improve their communication and problem-solving skills, individual and family coping skills, and medical management. Researchers more clearly described mechanisms of change in intervention studies with cancer and diabetes than with other diseases, and not surprisingly, they found greater empirical support for their interventions. Family interventions show promise to help patients and family members manage chronic illnesses. To develop an empirical base for family approaches to managing chronic illnesses, interventions must be based on theories that delineate mechanisms of change in family processes and skills in medical management necessary to maintain patients' and family members' health. 相似文献

About 50?years ago, Efron noted some counterintuitive properties of the long-term behavior of contests involving dice. For instance, consider the 6-sided dice whose sides are labeled (4,4,4,4,0,0), (3,3,3,3,3,3), (6,6,2,2,2,2), and (5,5,5,1,1,1). Each die has a 2/3 probability of rolling a higher number than the next one in the list and the last has the same 2/3 probability of rolling a higher number than the first. The non-transitivity of games involving non-identical dice was popularized by Gardner (Sci Am, 223:110–114, 1970). Although Gardner and other authors have observed that non-transitive dice serve to illustrate the complexities of the theory of voting, it does not seem that much attention has been paid to the corresponding voting system. Our purpose in this article is to present this voting system and compare its properties with those of other voting systems. One of the most interesting properties is the fact that cancellation with respect to the Efron dice voting system can replace cancellation with respect to pairwise preferences in Young’s characterization of the social choice function associated with the Borda Count. 相似文献

A child or adolescent with pediatric bipolar disorder (PBD) is at higher risk for suicide, violence, and impaired psychosocial functioning. The prevalence of diagnosed PBD has increased 40-fold in less than 2 decades, leading some to believe that PBD is inaccurately diagnosed. Complicating this issue, disagreements exist among clinicians as to the utility of current screening methods. The assessment picture is further muddied by the high rate of comorbid psychiatric conditions. A literature review was performed to describe the present understanding of PBD and identify current practices of screening for the disorder. Although screening tools are available, the literature suggests they lack validity. Awareness, a thorough interview, and expedient referral may assist clinicians in making a correct diagnosis. Accurate assessment will help ease the psychological and economic burden of PBD. 相似文献

Abstract Objective: The authors examine the dynamics and the impact of all-campus events on pH1N1 spread at Bates College in fall 2009, with comparisons to 3 other campuses. Participants: Students (N = 285) presented or called in to the Bates Health Center with symptoms consistent with influenza-like illness. Methods: Health Center staff at Bates collected data on the outbreak; data from other colleges are from Web sites and journal articles. Data were analyzed using a mathematical model for influenza. Results: Bates held 2 vaccine clinics mid-outbreak. The data are consistent with the hypothesis that the vaccine clinics may have altered routine student interactions, facilitating transmission of pH1N1 among students who otherwise might not have encountered each other. Conclusion: The vaccine clinics, held when vaccine became available, were too late to halt transmission. The disruptions to campus rhythms due to the vaccine clinics may instead have contributed to pH1N1 spread. 相似文献
