A comparison of factor analysis programs in SPSS,BMDP, and SAS

Factor analysis programs in SAS, BMDP, and SPSS are discussed and compared in terms of documentation, methods and options available, internal logic, computational accuracy, and results provided. Some problems with respect to logic and output are described. Based on these comparisons, recommendations are offered which include a clear overall preference for SAS, and advice against general use of SPSS for factor analysis.     

A comparison of the efficiency and accuracy of BILOG and LOGIST

Comparisons are made between BILOG version 2.2 and LOGIST 5.0 Version 2.5 in estimating the item parameters, traits, item characteristic functions (ICFs), and test characteristic functions (TCFs) for the three-parameter logistic model. Data analyzed are simulated item responses for 1000 simulees and one 10-item test, four 20-item tests, and four 40-item tests. LOGIST usually was faster than BILOG in producing maximum likelihood estimates. BILOG almost always produced more accurate estimates of individual item parameters. In estimating ICFs and TCFs BILOG was more accurate for the 10-item test, and the two programs were about equally accurate for the 20- and 40-item tests.I am grateful to Robert J. Mislevy, Martha L. Stocking, and Marilyn S. Wingersky for many helpful comments on an earlier version of this paper. I would also like to thank Hamid Kamrani and Bongmyoung Park for getting LOGIST and BILOG running and keeping them running under changing computer systems at CTB/McGraw-Hill.     

AN ANALYSIS OF THE PROCEDURAL COMPONENTS OF SUPPORTED EMPLOYMENT PROGRAMS ASSOCIATED WITH EMPLOYMENT OUTCOMES

This study examined the relation between the procedural components of supported employment programs and employment outcomes for 120 individuals with disabilities. These individuals were involved in supported employment programs established through the Utah Supported Employment Project. The results suggest that successful implementation of supported employment services led to ongoing employment of study participants in community work sites, increased wages, and ongoing opportunities for workers to interact with nondisabled peers. In addition, several procedural components were found to be strongly associated with successful employment outcomes for workers. Results of the study are discussed in terms of the training needs of supported employment program staff and future research for the dissemination of a cohesive technology of supported employment.     

Reductions in anxiety and improvements in teaching associated with cue-controlled relaxation training

This study examined the efficacy of cue-controlled relaxation, taught in three 2-hour workshops, in reducing the anxiety of two elementary school teachers. Anxiety was measured using direct observation of external behavior and self-report of internal states; and the effects of anxiety reduction on selected teaching behaviors were also examined. Following training, both teachers exhibited significant reductions in motoric manifestations of anxiety and in some self-reported internal states. Both teachers showed significant increases in rewarding behavior, and they reduced disapproving behavior to zero on most days. Even though results were not maintained following the treatment program, this study demonstrated that training in the self-management of stress and tension can significantly affect the anxiety and teaching behaviors of teachers.     

ON SYSTEMS ANALYSIS IN AUTISM INTERVENTION PROGRAMS

Although intervention technology has grown substantially during the past quarter century, the design of intervention systems has not grown apace. This paper examines organizational arrangements that enhance and diminish treatment effectiveness and argues that defining, measuring, and manipulating systemic antecedent and consequent variables are as important as assessment and intervention on an individual client's behalf.     

CREATING NEW REALITIES: PROGRAM DEVELOPMENT AND DISSEMINATION

Program development and dissemination in human services present challenges and opportunities for social scientists. Over the past 27 years the Teaching-Family Model of group home treatment has moved from prototype development to widespread dissemination across North America. Reviewing concepts in industry related to product development and dissemination, the application of these concepts to a human services delivery system, and program replication and dissemination data offer information about how innovative human services can be widely adapted and adopted.     

Multimedia Field Test: Digitalizing Better Sleep Using the Sleepio Program

The promise of online cognitive behavioral therapy for insomnia (CBT-I) and other sleep-related problems as an alternative to traditional face-to-face treatment rests upon the accessibility, ease-of-use, and effectiveness of these approaches. Here we provide a review of Sleepio, a digitalized, state-of-the-art CBT-I program for adults, informed by our personal experience with the program, available research, and information provided at the Sleepio website. The 6-week treatment program can be completed flexibly via web-based or mobile platform. Initial assessment of individual goals and baseline sleep patterns is used to build a personalized account comprised of four sections: Sleep Diary, Case File, Library, and Community. Sleepio uses evidence-based principles and practices, engaging content, and an easy-to-follow format. Unique features of the program including synchronization with compatible sleep tracking devices, multiple built-in user supports, and a 14-day money-back guarantee. Both statistical and clinically meaningful sleep improvements have been found in a large randomized controlled trial. Overall, Sleepio represents a model program for online CBT-I delivery.     

Wraparound care in vermont: Program development,implementation, and evaluation of a statewide system of individualized services

Over the past decade, there has been a dramatic shift in the provision of mental health services to children, adolescents, and their families. This shift has been marked by a movement away from restrictive treatment options toward the development of comprehensive community-based systems of care designed to keep the most challenging children in their homes, schools, and communities. Based on a model of intensive case management referred to as Wraparound Care, Vermont's statewide approach emphasizes aggressive outreach, use of the least restrictive treatment options, and care that is flexible, unconditional, and child- and family-centered. We chart the development of Vermont's Wraparound Care Initiative and present residential, educational, and behavioral outcome data for a cohort of 40 youth receiving Wraparound Care over a 12-month period. The results showed that after 12-months, youth who had been previously removed from their homes or were at imminent risk of such removal, were residing in significantly less restrictive community-based living arrangements and exhibiting significantly fewer problem behaviors than at intake. These results are discussed in light of recent national studies and previous studies on similar cohorts of Vermont youth receiving Wraparound Care.     

Adult urinary incontinence: Assessment,intervention, and the role of clinical health psychology in program development

Urinary incontinence (UI) is a disorder receiving little attention from clinical health psychologists. This paper establishes the importance of addressing the issue of UI within the clinical and research practices of clinical health psychologists. Over 10 million Americans suffer from loss of bladder control. Incontinence affects over half of older individuals in long-term care institutions, about one-third of hospitalized elderly, and up to 30% of Americans over the age of 60 living at home. Because of social stigma and misconceptions attached to urinary incontinence, it is estimated that less than half of those affected see a physician about their condition. Since UI is generally associated with medical, social, psychological, and economic consequences, a multidisciplinary perspective is important because these factors are integral in the selection of appropriate treatment. Definitions of UI, its incidence and costs, and brief reviews of treatment and management techniques are presented. Psychological sequelae and treatments are presented as a foundation for developing further treatment and research approaches. Guidelines for collaboration and consultation by clinical health psychologists with medical professionals in the area of UI are also discussed.     

A scale to assess the restrictiveness of educational settings

The placement of students into educational settings is perhaps one of the most debated issues in special education, particularly for students with emotional and behavioral disorders (EBD). A primary consideration in this decision is the restrictiveness of the setting, yet no scale to assess restrictiveness of educational settings exists. We undertook two surveys that asked respondents to rate the restrictiveness of 18 educational placements. The first survey was sent to a national panel of experts, the second survey was sent to supervisors of programs for students with EBD. The results of the surveys led to the development of theScale to Assess Restrictiveness of Educational Settings. This scale is designed to provide a measure of restrictiveness of educational settings that can provide data to evaluate student progress and program outcomes.
