Racial identity means different things to members of different racial and ethnic groups in the United States. However, while the study of race and politics is often the study of White racial attitudes ( Dawson & Cohen, 2003 ), research on racial identity almost always refers to non-White identity. This article addresses this hole in the literature by examining the extent and effects of White identity. We compare White identification and Black identification using National Election Studies data (1972–2000) and examine the relationships between racial identity and racial and political attitudes. This study adds a missing case to the study of racial identity, tests how well the theories about the concept travel across cases, and highlights the need for more frequent studies of the racial identity of all groups. 相似文献

Following a landmark component analysis of cognitive therapy by Jacobson and colleagues (1996), there has been renewed interest in behavioral activation (BA) treatments for depression. The Behavioral Activation for Depression Scale (BADS) was developed to measure when and how clients become activated over the course of BA treatment. Multiple studies have provided initial support for the BADS but have also identified several potential problems. Four studies were conducted in order to develop and provide initial evaluation of a short form of the BADS that addresses these concerns. In Study 1, an exploratory factor analysis was conducted on existing data using the original BADS in order to identify items to retain for the short form. In Study 2, these items were administered to a new sample of college students with elevated depressive symptoms and were analyzed with exploratory and confirmatory factor analyses. Study 3 examined the predictive validity of the BADS-SF by examining the BADS-SF and depression scores in relation to activity tracking and reward-value ratings over the course of 1 week. Study 4 examined BADS-SF data over the course of BA treatment for two clients using cross-lagged panel correlations. With one client, changes in BADS-SF scores led changes in depression scores by 1 week, whereas with the other client changes in BADS-SF and depression scores occurred concurrently. These studies resulted in a nine-item scale that demonstrated good item characteristics as well as acceptable internal consistency reliability, construct validity, and predictive validity. 相似文献

The movement toward evidence-based treatments, interventions, or practices pressures single case research (SCR) to use statistical summaries which have broad credibility. These summaries also need to be easily understood and useful in schools and clinics. To date the effect size families, “proportion of variance” (R2, Eta2) and “standardized mean difference” (Cohen's d, Hedges' g) have little popularity in SCR. This paper demonstrates a set of alternative Clinical Outcome indices widely used in the field of medicine: Risk Difference, Relative Risk, Relative Risk Improvement, and Odds Ratio, which compare patients in treatment versus control conditions. Translated to SCR designs, the baseline phase becomes the control condition, the intervention phase becomes the treatment condition, and improvement is defined as non-overlapping data between phases. The positive attributes of Clinical Outcomes are demonstrated: (a) easily interpretable results, (b) close relationship with concept of non-overlapping data, (c) minimal data assumptions, (d) minimal statistical expertise required, (e) multiple contrasts possible for diagnostic understanding, (f) exact confidence intervals for results, and (g) close relationship to Pearson R effect size family. 相似文献

This study examined patterns of growth across benchmark assessments for curriculum-based measures (CBM) over 2 academic years, with the twofold purpose of replicating earlier findings of growth patterns on R-CBM and conducting a preliminary investigation of growth patterns on M-CBM and CBM-Maze. The sample included 898 cases from 3rd through 5th grade over 2 academic years from one elementary school in the rural Midwest. All students participated in tri-annual benchmark assessments in which they were administered R-CBM, CBM-Maze, and M-CBM. Repeated measures analysis of variance was used to examine patterns of growth for all three measures. Students demonstrated greater R-CBM weekly growth during winter-to-spring than fall-to-winter across grade levels. Patterns for CBM-Maze and M-CBM were somewhat inconsistent across school years and grade levels. Results are discussed in terms of contextual variables that may impact within-year growth patterns and technical characteristics of CBM slopes. 相似文献

Performance Indicators in Math: Implications for Brief Experimental Analysis of Academic Performance
Brief experimental analysis (BEA) can be used to specify intervention characteristics that produce positive learning gains
for individual students. A key challenge to the use of BEA for intervention planning is the identification of performance
indicators (including topography of the skill, measurement characteristics, and decision criteria) that meaningfully relate
to longer term success in the learning environment. This study investigates the utility of various curriculum-based assessment
and measurement estimates of mathematics performance for predicting functional outcomes (i.e., retention of learned skills
over time and faster learning of related content in the future). All children in grades 2–5 at the participating school participated
in protocol-based computational fluency-building intervention 4 days per week for an entire school year. Specific criteria
were applied each week to systematically increase intervention difficulty classwide according to a pre-established sequence
of computational skill objectives. Three measurements were routinely obtained. Each week children completed a timed probe
of the skill for which intervention was currently occurring and a timed probe of previously mastered skills from the sequence
of computational skill objectives. Each month, all children completed a timed probe of mathematics skills representing computational
skills that students were expected to master by year’s end at each grade level. At all grade levels, learning a skill that
appeared early in the hierarchy or sequence of skills related positively to learning of future related and more complex computational
skills. Fluency criteria were specified that predicted retention of the skill over several months. 相似文献

在慢性胃炎研究上决策树归纳法之使用已渐增加,以决策树归纳法同时表示信息增益以区别胃炎症状对证型分类之贡献,能更正确地区别慢性胃炎。而信息增益已广泛地用于评估两分分类,仅有很少报导有关多类别慢性胃炎分类,它需要探索多类别慢性胃炎分类之信息增益。本研究提出基于名目及次序样本类结果的决策树归纳法所做的多类别慢性胃炎分类,例如,不同慢性胃炎次型的症状样本,评估是以决策树归纳法与Friedman-Goldszmid,HGC,Cheng判别法之正确率作比较。显示平均正确率64.9%优于前三者且提高1.55%。 相似文献

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and
polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered
in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological test. A weak item independence
axiom W2 postulates that the order of the items is similar for all subjects. Local independence (LI or W3) is assumed in all
models. With these axioms, sample-free unidimensional ordinal measurements of items and subjects become feasible. A cancellation
axiom (Co) gives, as a result, the additive isotonic psychometric (ADISOP) model and interval scales for subjects and items,
and an independence axiom (W4) gives the completely additive isotonic psychometric (CADISOP) model with an interval scale
for the response variable (Scheiblechner, 1999). The d-ISOP, d-ADISOP, and d-CADISOP models are generalizations to d-dimensional dependent variables (e.g., speed and accuracy of response).
