MMPI factor analytic findings for adolescents: item- and scale-level factor structures

Although numerous studies have examined the factor structures of the Minnesota Multiphasic Personality Inventory (MMPI) in investigations of adults, very little attention has been directed to this issue in adolescent samples. In this study, we investigated the item-level and scale-level factor structures using a sample of 1,762 adolescents receiving psychiatric services at the time of their MMPI assessment. Results identified 17 factors related to item responses and 5 factors based on scale-level data. Findings are discussed in relation to results obtained in adult populations and the potential utility of factor analytically derived content scales for adolescent MMPI interpretation.     

ALICE: A system for manipulating and analyzing multidimensional data

The computer program ALICE solves the two major problems of data manipulation and analysis. First, ALICE allows the user to treat data from an experiment in the form they are generated. Second, mathematical calculations and statistical analyses are included as an intrinsic part of the multidimensional approach to data handling. ALICE accepts raw data in the form and order they were collected; reorganizes, partitions, or selects any subset of them (including a single entry), and arithmetically combines, transforms, or evaluates any formula involving them. Furthermore, learning to use ALICE is simple, even for those who are naive to both computers and data analysis.     

表演心理学与社会治疗

从后现代主义心理学思潮中脱颖而出的社会治疗最初是由美国心理学家弗莱德·纽曼创建于20世纪70年代,其理论基础是路易斯·赫兹曼等人提出的表演心理学。表演心理学融合了当前学科研究的趋势,是对主流心理学的挑战。表演心理学的社会治疗观并不是直接帮助人们解决现有问题,而是通过发展创造性的表演活动为人们构建一种全新的生活形式。     

Statistical power analyses using G<Superscript>*</Superscript>Power 3.1: Tests for correlation and regression analyses

G^*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses. In the new version, we have added procedures to analyze the power of tests based on (1) single-sample tetrachoric correlations, (2) comparisons of dependent correlations, (3) bivariate linear regression, (4) multiple linear regression based on the random predictor model, (5) logistic regression, and (6) Poisson regression. We describe these new features and provide a brief introduction to their scope and handling.     

The development of the Children's Empathic Attitudes Questionnaire using classical and Rasch analyses

Empathic responding is implicated in antisocial behaviors such as bullying, sexual offending, and violent crime. Identifying children and adolescents at risk for antisocial behavior and evaluating interventions designed to address problem behaviors require valid and reliable measures. Definitional controversies and limited measurement models have hindered measurement. This study describes the development and analysis of the Children's Empathic Attitudes Questionnaire (CEAQ) using both classical and modern techniques. Rasch analyses provided probabilistic results over large item and person groups, enabling meaningful inferences from patterns of responses at the construct level. Analyses of fifth through seventh graders' responses to the final version of the CEAQ provide support for its reliability, validity, and functionality. Four meaningful item clusters were identified, each reflecting more cognitively advanced empathic attitudes. These analyses suggest that the CEAQ provides a theoretically sound, hierarchically meaningful measure of empathic attitudes that will be useful in identification and intervention with children and adolescents at risk for antisocial behavior.     

Technology, Methodology and Intervention: Performing Nanoethics in Portugal

During the last few decades we have witnessed a proliferation of exercises dealing with the public participation of citizens in various different dimensions of their societies, including issues of science and technology. On the one hand, these mechanisms provide more robust forms of public engagement with matters that were traditionally dealt with by experts; on the other hand, they raise concerns relating to their design, efficiency or potential for the empowerment of citizens. As part of the EC-funded project DEEPEN (Deepening Ethical Engagement and Participation in Emerging Nanotechnologies) a research team in Coimbra, Portugal, was put in charge of identifying the ethical and social “impacts” of emerging nanotechnologies, transforming the traditional focus groups through the incorporation of two methodological innovations: the Pedagogy of the Oppressed and the Theatre of the Oppressed. This article reflects on the outcomes and complexities of the introduction of these two methodologies. Since the participants had little or no information on nanotechnologies, we reflect on the politics of these focus groups by exploring how issues of intervention, subjectivity, representation and agency were interconnected during this exercise of public participation in Science and Technology, analyzing the role of social sciences in developing nanoethics.     

Preferred and Nonpreferred Hand skill in Performing Four Industrial Tasks

The purpose of this study was to test the relative speed and accuracy of the nonpreferred hand in performing bolt twisting, tweezer manipulation, drilling, and nail-driving tasks. Thirty-six adults performed the tasks in that order, holding the tools in the nonpreferred hand half the time. Significant differences in task time scores occurred with tweezers and hammering, but not with bolts and drilling. Similarly, the hands did not differ in drill-aiming accuracy. Scores on the second day revealed learning for the tweezers task, but not for hammering. These results appear to have application to the cumulative trauma disorder problem.     

The Enhancement of Performance Excellence Among Performing Artists

With the maturation of the practice of applied sport psychology has come recognition of the ways in which knowledge of performance excellence can address performance issues among other populations. The present article addresses applications to performing artists. Four issues that may affect performing artists, and that have direct parallels within sport, are performance enhancement and psychological skills training, developmental issues, injury and retirement, and eating disorders. Performing artists' preferences and concerns about consultation are discussed, noting parallels and differences with applications to athletes. Both practical and ethical considerations of developing such a practice are reviewed.     

表演心理学:一种新的研究取向

表演心理学是20世纪70年代在美国兴起的新的心理学研究思潮。表演心理学在对主流心理学挑战的基础上提出了发展式表演的理论,该理论致力于唤起人们对生活中表演维度的注意,并试图通过发展式表演来改进人类生存环境、提高人类的生活质量。当前关于表演心理学的研究主要集中在社会治疗、教育改革与社会变革等方面。作为一种新的研究取向,表演心理学还有其不完善之处,但其发展式表演的理论及其应用正被更多的人所接受。     

四卡问题解决中的内容与逻辑分析效应

选取条件概率(P(Q|P))由低到高的四个命题作为四卡问题中的检验规则,探讨了大学生被试对四张卡片的逻辑证明作用的推断能力及其对解决四卡问题的影响。结果发现:(1)不同条件概率的命题之间正确选择P-Q的人数百分比不存在显著差异,命题的条件概率因素对四卡问题的正确解决没有影响。(2)逻辑分析过程对四卡问题的正确解决产生了一定的抑制作用,这可能是因为被试不能从整体上思考四张卡片在命题检验中的逻辑作用的缘故。(3)一些被试即使在逻辑分析过程中表现出知道-Q卡片的证伪作用,仍然倾向于选择卡片Q而非-Q,这一现象再次证实了人类思维的非形式逻辑的一面。     

Cognitive Organization of Favorable and Unfavorable Beliefs About Performing a Behavior

Abstract

Intentions to perform behaviors are influenced by beliefs about their consequences, but researchers have not addressed how such beliefs are cognitively organized. In 3 experiments, the authors tested the hypothesis that beliefs are organized according to whether they are favorable or unfavorable in regard to performing a behavior. In Experiment 1, a group of U.S. students first read a list of beliefs favorable and unfavorable to going to a vacation resort and then listed their beliefs about condom use. In Experiment 2, another group of U.S. students listed their beliefs about condom use. In Experiment 3, a 3rd group of U.S. students listed their beliefs about a novel behavior (asking the experimenter for candy). The results of all 3 experiments were consistent with the hypothesis that people cognitively organize their beliefs according to whether they are favorable or unfavorable to the behavior in question.     

Robust and powerful nonorthogonal analyses

Numerous types of analyses for factorial designs having unequal cell frequencies have been discussed in the literature. These analyses test either weighted or unweighted marginal means which, in turn, correspond to different model comparisons. Previous research has indicated, however, that these analyses result in biased (liberal or conservative) tests when cell variances are heterogeneous. We show how to obtain a generally robust and powerful analysis with any of the recommended nonorthogonal solutions by adapting a modification of the Welch-James procedure for comparing means when population variances are heterogeneous.This research was supported by a Social Sciences and Humanities Research Council (SSHRC) grant (# 410-92-0430) to the first author, a Manitoba Health Research Council Scholar Award and a grant from Natural Sciences and Engineering Research Council to the second author, and a SSHRC Doctoral Fellowship (# 752-92-1628) to the third author. The authors would like to express their gratitude to Joanne Keselman and three anonymous reviewers for their many helpful substantive comments on earlier drafts of this paper.     

Performing DISCO-SCA to search for distinctive and common information in linked data

Behavioral researchers often obtain information about the same set of entities from different sources. A main challenge in the analysis of such data is to reveal, on the one hand, the mechanisms underlying all of the data blocks under study and, on the other hand, the mechanisms underlying a single data block or a few such blocks only (i.e., common and distinctive mechanisms, respectively). A method called DISCO-SCA has been proposed by which such mechanisms can be found. The goal of this article is to make the DISCO-SCA method more accessible, in particular for applied researchers. To this end, first we will illustrate the different steps in a DISCO-SCA analysis, with data stemming from the domain of psychiatric diagnosis. Second, we will present in this article the DISCO-SCA graphical user interface (GUI). The main benefits of the DISCO-SCA GUI are that it is easy to use, strongly facilitates the choice of model selection parameters (such as the number of mechanisms and their status as being common or distinctive), and is freely available.
