Rotation test with pairwise distance measures of sample vectors in a GLM

One way to cope with high-dimensional data even in small samples is the use of pairwise distance measures—such as the Euclidean distance—between the sample vectors. This is usually done with permutation tests. Here we propose the application of exact parametric rotation tests which are no longer restricted by the finite number of possible permutations of a sample. The method is presented in the framework of the general linear model.     

A Pilot for Improving Depression Care on College Campuses: Results of the College Breakthrough Series–Depression (CBS-D) Project

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.     

Eliciting survey cooperation: incentives, self-interest, and norms of cooperation

Given the weaker ties to community as noted by scholars such as Robert Putnam, survey researchers should not be surprised by a decline in survey participation over the past 10 years. This research analyzes the use of incentives coupled with introductory themes emphasizing cooperation and helpfulness--cooperative norms in American society--to understand their effects on survey response. This article analyzes two separate experiments (one phone and one mail) that provide evidence that norms of cooperation matter in the decision to participate in a survey, suggesting that this is particularly true at the refusal conversion stage. These results indicate that survey researchers may use such themes to their advantage, especially when conducting a nonresponse follow-up in a mail survey.     

Increasing aging content in social work curriculum: perceptions of key constituents

This mixed methodology study examines the perceptions of key constituents regarding methods for effectively integrating aging content into the foundation curriculum of the BSW and MSW program at the University of Georgia School of Social Work. Students were asked to complete a survey to determine their perception of geriatric content that existed within the foundation coursework. Following an analysis of the survey results, eight semi-structured focus group discussions were conducted with a purposeful sample of students, faculty, field instructors, social work alumni, older adults from the community, and representatives from aging agencies. The intention of these focus groups was to find out what aging content should be infused within the curriculum. The focus group meetings were held in various locations throughout Northeast Georgia and in one remote location in South Georgia. Participants were interviewed about the necessary skills and knowledge for social workers practicing with an aging population in the areas of: essential intervention skills, program policies and regulations, critical information needed to develop client service plans, strategies for addressing service delivery fragmentation, and community collaboration to support intergenerational family needs. The results of this study will be discussed to provide suggestions on how existing foundation courses can integrate aging content.     

Predictors of Depression Among Caregivers of Older Adults With Severe Mental Illness

Caregivers of older persons with severe mental illness (SMI) contend with the double challenge of providing assistance related to both the psychiatric condition and older age of their family member. Study explored factors influencing negative psychological outcomes experienced by caregivers (n = 96) of older adults with SMI. One-quarter of caregivers scored at or above the clinical point for depression. Low income, care recipient gender, poor health, problems dealing with care recipient’s symptoms and the interaction of health and problems dealing with symptoms were associated with higher rates of depression. Implications for service provision and future research are discussed.     

Aging with a severe mental illness: challenges and treatments

Severe mental illness (SMI) impacts many different facets of individuals' lives. As they age, those with SMI experience increased physical illnesses, functional impairment, cognitive deficits, and social disability. To promote more effective social work practice with this population, this article highlights the major biopsychosocial and family issues of aging with a psychiatric diagnosis. In addition, intervention approaches that have demonstrated efficacy are summarized along with ways to coordinate services across multiple service delivery sectors. Finally, future directions in practice and research are presented to develop additional methods of support for older adults with SMI and their families.

Ballot Design and Unrecorded Votes on Paper-Based Ballots

The 2000 presidential election focused attention on the problemof unrecorded votes, in which a person casts a ballot but failsto record a valid vote for a particular contest. Although muchrecent research has evaluated voting technologies and theireffects on unrecorded votes, there has been little researchon the effects of ballot design. We argue that the same theoriesused to design and evaluate self-administered surveys can beused to analyze ballot features. We collect and code paper-basedballots used in the 2002 general election from 250 countiesin 5 states. We code the ballots in terms of several graphicdesign elements, including the content and location of ballotinstructions and the layout of candidate names and office titles.Our analysis suggests that several ballot features are associatedwith unrecorded votes (both overvotes and undervotes) in thegubernatorial contests. We also find that ballot design featuresexacerbate the racial disparity in unrecorded votes. Ballotdesign can be an important factor in determining whether votersare able to cast a ballot accurately, which can influence thelegitimacy of elections.
