In this article, the authors describe the refinement and preliminary evaluation of the Dimensions of Change in Therapeutic Community Treatment Instrument (DCI), a measure of treatment process. In Study 1, a 99-item DCI, administered to a cross-sectional sample of substance abuse clients (N = 990), was shortened to 54 items on the basis of results from confirmatory factor analyses and item response theory invariance tests. In Study 2, confirmatory factor analyses of the 54-item DCI, completed by a longitudinal cohort of 993 clients, established and validated an 8-factor solution across 2 subpopulations (adults and adolescents) and 2 time points (treatment entry and 30-days postentry). The results of the 2 studies are encouraging and support use of the 54-item DCI as a tool to measure treatment process. 相似文献

The report from President George W. Bush’s New Freedom Commission on Mental Health (NFC), Achieving the Promise: Transforming Mental Health Care in America(2003), proposes goals and recommendations for improving mental health services. This report has significant implications
for the delivery of mental health services through the schools. A focused discussion of the potential opportunities and challenges
of implementing NFC recommendations related to school-based mental health is presented. Strategies for addressing five key
areas at the intersection of school mental health and the Commission’s recommendations include: stigma reduction, suicide
prevention, expansion and improvement of school mental health, and screening and treatment of co-occurring mental health and
substance abuse disorders. 相似文献

Although recent research has identified numerous variables that can affect behavior maintained by negative reinforcement, questions remain concerning the potential aspects of the demand context that evoke problem behavior. To date, few studies have examined these questions within general education classrooms. The current study assessed the influence of social and task-difficulty variables on problem behavior maintained by negative reinforcement. Teachers in general education classrooms implemented three analyses to determine the influence of these variables on the problem behavior of 4 boys. Results are discussed in terms of response covariation within the demand context. 相似文献

The purpose of this study was to determine if a developmental order exists in the metalinguistic ability of children to make judgments about the form of language while simultaneously attending to a meaningful linguistic context. The stimulus material consisted of a short story into which 20 nonsense lexical items had been substituted. The 20 stimuli were comprised of phonotactically illegal and legal sequences of phonemes. In addition, the lexical items had been positioned to replace either structure or content words within the story. The participants were 90 Caucasian children who were divided into nine age groupings from 4;0 to 12;11. Baseline data were obtained from 10 adults. All subjects were required to respond to the audio-recorded stimuli by pressing a button whenever a nonsense item was perceived. The data were analyzed for both number of correct responses and reaction times. Results revealed a major shift in metalanguage ability occurring between 7 and 8 years of age. The 8- to 12-year-olds responded correctly to more items and at significantly faster rates than the 4- to 7-year-olds. The adults outperformed the children on all tasks, showing that metalanguage development continues beyond childhood. 相似文献

We investigated the recovery from memory of a primary task after an interruption. If the primary task lacked associative support among its task components, recovery was more difficult following an interruption that overlapped either completely or partially in the amount of information shared with the primary task (an interruption-similarity effect). In addition, memory for completed actions was superior to memory for impending unfinished actions. However, if the primary task had associative support among its task components, there was no adverse effect of interruption similarity, and completed and unfinished actions were recalled equally well. We explore possible explanations and implications of these results. 相似文献

This paper is an attempt to provide a critical evaluation of the theory of disability put forward by Lennart Nordenfelt. The paper is in five sections. The first sets out the main elements of Nordenfelt's theory. The second section elaborates the theory further, identifies a tension in the theory, and three kinds of problems for it. The tension derives from Nordenfelt's attempt to respect two important but conflicting constraints on a theory of health. The problems derive from characterisation of the goals of persons; the difficulty which Nordenfelt has in respecting the plausible view that there is a distinction between illness and disability; and the presence in the theory of other strongly counter-intuitive implications. In section three a defence of Nordenfelt is attempted from within the resources available within his own theory. This defence seeks to exploit his distinctions between a person who is ill and one who is generally disabled and that between first- and second-order disabilities. However, it is concluded that there are insufficient resources within Nordenfelt's theory to fend off the criticisms developed in section two. The fourth section of the paper attempts a defence of Nordenfelt. It is claimed that introduction of the concept of capacity helps to explain differences between problem cases in the theory. Finally, it is shown that at least two important constraints on any theory of disability emerge from the preceding discussion. 相似文献

This paper presents two approximate methods for multiattribute utility measurement, SMARTS and SMARTER, each based on an elicitation procedure for weights. Both correct an error in SMART, originally proposed by Edwards in 1977, and in addition SMARTER is simpler to use. SMARTS uses linear approximations to single-dimension utility functions, an additive aggregation model, and swing weights. The paper proposes tests for the usability of these approximations. SMARTER, based on a formally justifiable weighting procedure developed by Barron and Barrett, uses the same procedures as SMARTS except that it omits the second of two elicitation steps in swing weights, substituting calculations based on ranks. It can be shown to perform about 98% as well as SMARTS does, without requiring any difficult judgments from elicitees. 相似文献

Relationship between Type A behavior pattern and mental and physical symptoms: a comparison of global and component measures 总被引:2,自引:0,他引:2
Although the Type A behavior pattern (TABP) is typically considered a set of distinct components, most studies of TABP have used global measures, which collapse several components into a single index. These measures are inherently multidimensional and, as such, contain several conceptual and methodological problems. In this study, data from 240 executives were used to compare global and component TABP measures as predictors of mental and physical symptoms. Global measures included the Bortner scale, the Framingham scale, and the Jenkins Activity Survey. Component measures were constructed by recombining items from the global measures on the basis of results from previous confirmatory factor analyses (Edwards, Baglioni, & Cooper, 1990). Results indicate that the component measures were superior to the global measures in terms of number of relationships detected, interpretability, and total explanatory power. Implications for research and practice are discussed. 相似文献
