A rank testR n has been proposed by Cronholm and Revusky which in effect increases the number of observations per subject by the device of randomly assigning a subject to a treated group in each of a series of sub-experiments. In this note further results on the asymptotic normality of theR n test are discussed both under the null hypothesisH 0 of randomness and under a class of alternatives toH 0. The limiting power of the test is also discussed.  相似文献

To assess the efficacy of an interpersonal process-oriented and cognitive-behavioral group psychotherapy program, 36 incarcerated male adults were assigned to either a treatment group (n = 20) or a no treatment control group (n = 16). Outcome measures consisted of paper-pencil self-report instruments, institutional behavioral data, and structured interviews with the group therapists (n = 3). Results indicated no significant changes in inmates' level of defensiveness, empathy, or institutional behavior; however, the inmates reported universally positive reactions to the treatment program. The group therapists also perceived the treatment program as efficacious, particularly in fostering a cohesive group atmosphere and increasing inmate responsibility for group leadership. Implications for practice and research are discussed.  相似文献

Research on self‐regulation has largely focused on the idea of effortful self‐control, which assumes that exerting willpower will lead to greater success. However, in recent years, research has challenged this perspective and instead proposes that effortless self‐regulation is more adaptive for long‐term goal pursuit. Taking into consideration the burgeoning literature on effortless self‐regulation, here we propose that motivation—or the reasons why we pursue our goals—plays an integral role in this process. The objective of the present paper is to highlight how motivation can play a role in how self‐regulation unfolds. Specifically, we propose that pursuing goals because you want‐to (vs. have‐to) is associated with better goal attainment as a function of experiencing less temptations and obstacles. While the reason why want‐to motivation relates to experiencing fewer obstacles has yet to be thoroughly explored, here we propose some potential mechanisms drawing from recent research on self‐regulation. We also provide recommendations for future research, highlighting the importance of considering motivation in the study of self‐regulatory processes.  相似文献

Two kinds of difficulties, which should be made explicit, face a researcher undertaking empirical work in an institution. First, he must explain how he chooses his theoretical framework, in so far as what he sees and the information he obtains will depend far more than is often admitted on the type of questions he asks. Secondly, he must try to clarify the way in which he adapts his original intentions in the light of the practical difficulties that occur in the actual research situation, and how he interprets the evidence he finally decides is relevant. These points are illustrated by the study of an ‘open’ Borstal for girls. The aim of the study was to try to understand the workings of the institution, to outline the process which led to the Borstal sentence, and to attempt to discover the way the girls looked at the situation. The research was motivated by Matza's guiding principle, ‘to be true to the phenomena’, but even this, as this paper tries to show, does not lead to an unambiguous body of facts which can be presented unequivocally as ‘findings’.  相似文献

Editor's Note: With this issue we begin a new section of HCR which is devoted to brief reports of research. This section is devoted to research which is designed to replicate previous work, papers which report new measures for which insufficient validity data are yet available, and studies which are meaningful but do not permit major advancement of communication theory. “Brief Reports” are held accountable for both conceptual and methodological adequacy and are reviewed by the regular HCR editorial board. Submission requires that the author provide a full-length paper for editorial review and, should the paper be accepted for publication, provide copies of the full paper to HCR readers who request same. Submission of ‘Brief Reports’ is actively encouraged by the editor. For submission guidelines, see the Fall 1978 issue of HCR (vol. 5, pp. 2–3).  相似文献

Summary The paper gives a tentative reconstruction of the classical theory of so called fallacious arguments. Its title refers to the following observations. One of the fallacies listed in traditional logic ispetitio principii. It seem natural to add to the list another, similar fallacy. An argumentationArg + considered as a part of a theoretical contextC commits this fallacy relatively toC, if it contains an inference such that the principle of this inference has not been proved inC. By principle of a given inference the conditional is meant whose antecedent and consequent are the conjuction of all the premisses and the conclusion of the inference respectively. If the principle of a given inference has been proved in a given contextC, the inference is valid relatively toC and the premisses are implying the conclusion relatively toC. Both these concepts, of valid inference and of implication do involve the concept of an effectively performed proof; hence they are pragmatic concepts.  相似文献

Research on leadership behavior in therapy groups emphasizes the need for precise theories and clinically meaningful instruments to study leadership variables. This paper reviews the development of the Group Leader Behavior Instrument (GLBI) and investigates its relationship to an earlier measure, the Group Leadership Questionnaire (GTQ-C). Both instruments were completed by 40 practicing group therapists. Analyses confirm a moderate degree of similarity between the leadership profiles obtained from the GLBI and GTQ-C. Differences due to the construction of the two scales are also examined. The authors conclude with a discussion of the potential uses of the GLBI to assess leadership behaviors in ongoing groups, to train group therapists, and to further progress in process and outcome research on group leadership.The authors thank Dr. Mary Fox, Director of the Group Therapy Program, Department of Psychiatry, University of Rochester, for her continued support in this work.  相似文献

Ted Gioia associated the “aesthetics of imperfection” with improvised music. In an earlier article, I extended it to all musical performance. This article reconceives my discussion, offering more precise analyses: (1) The aesthetics of imperfection is now argued to involve open, spontaneous response to contingencies of performance or production, reacting positively to idiosyncratic instruments; apparent failings in performance, and so on. Perfectionists, in contrast, prefer a planning model, not readily modified in face of contingencies. (2) Imperfection is not toleration of errors and imperfections, as Gioia assumes, but a positive aesthetic, as in Japanese wabi-sabi. Imperfections can become new styles or kinds of perfection—and so true imperfectionism is a constant striving for new contingencies to respond to. (3) A subtler, more complex relation between composition and improvisation is proposed, in which both have broad and narrow senses. Composition involves (a) works, usually desk produced and notated; or more generally, (b) putting things together in an aesthetically rewarding form. Thus, improvisation is a (broad sense) compositional method. (4) Improvisation and composition are interdependent; both involve structure and spontaneity. (5) Imperfectionism is an aesthetics of performance—of compositions as well as improvisations. Improvisation is no risker, or prone to mistakes, than performance of compositions.  相似文献

Background A number of instruments have been developed for investigating relationships between spirituality and health, and have been used to assess spirituality in African-Americans. Yet, the cultural appropriateness for African-Americans of these instruments has not been investigated to date. Objectives To evaluate the construct validity and reliability of spirituality measures used in health research from 1982 to 2005. Method Systematic review of the literature. Results Thirty five studies and five measures of spirituality met the inclusion criteria. Most of the spirituality measures were developed in primarily Caucasian-American samples. African-Americans were represented in 71% of the studies (n = 25) using spirituality measures in health research. Distinct cultural attributes of African-American spirituality were omitted in most of the spirituality measures. Two studies were retrieved in which psychometric evaluation was conducted in entirely African-American samples. Discussion Spirituality is a significant cultural experience and belief that influences the health behaviors of African-Americans. The lack of a culturally appropriate measure of African-American spirituality is a major limitation of studies investigating spirituality and health in this population. Development of a culturally appropriate and sensitive measure of spirituality in African-Americans is suggested to strengthen the quality of research in this area.  相似文献

In this essay I refine and greatly expand the scope of my 1987 theory of why religious groups succeed or fail. The initial version was limited to new religions (cult movements). This version applies to all movements, including sects. The theory now consists of 10 propositions which attempt to specify the necessary and sufficient conditions for success or failure.  相似文献

The Dysfunctional Attitude Scale (DAS) was designed to measure patterns of maladaptive thinking held by depressed individuals. Despite its wide use as a research and clinical tool, only a few studies to date were designed to examine its psychometric properties in a clinically depressed population. Moreover, problems of low sample size and limited tests of validity call these findings into question. The present study was designed to examine psychometric properties of the DAS in clinically depressed inpatients and in nondepressed clinical controls. Intertest correlations between the DAS parallel forms and between each form with total test scores ranged from r=.84 to r=.97. Intratest stability coefficients were r=.88 to r=.97. Support for the DAS as a valid measure of dysfunctional cognitions in depressed patients was also indicated. Of those scoring high on the DAS, 73% received an independent RDC diagnosis of clinical depression, while only 36% of those receiving low DAS scores were so diagnosed.  相似文献

Aim: Given that various systematic reviews of supervision literature have revealed how little is known about supervision, that studies are not usually routed in practice, and that a multitude of diverse measures are used, the primary aim of this project was to support and encourage practitioner research related to supervision using a prescribed common set of instruments. Method: Funded by the British Association for Counselling and Psychotherapy (BACP), a Supervision Research Practice Network (SuPReNet) was established. A toolkit (a series of measures) that could be used routinely by practitioners was selected following the assembly of available measures of supervision and an assessment of them. Findings: The appraisal, conducted by the three authors, yielded five core measures, free for anyone to use, and accessible through the SuPReNet website. The measures are being piloted through a practice research network at a university counselling and psychotherapy research clinic where supervision data are being collected through a special module of CORE Net. Discussion: The potential yield from this initiative for practitioners, researchers, and the developing evidence‐base is discussed and a model proposed for the next generation of research on supervision.  相似文献

To help infer the meanings of novel words, children frequently capitalize on their current linguistic knowledge to constrain the hypothesis space. Children's syntactic knowledge of function words has been shown to be especially useful in helping to infer the meanings of novel words, with most previous research focusing on how children use preceding determiners and pronouns/auxiliary to infer whether a novel word refers to an entity or an action, respectively. In the current visual world experiment, we examined whether 28- to 32-month-olds could exploit their lexical semantic knowledge of an additional class of function words—prepositions—to learn novel nouns. During the experiment, children were tested on their ability to use the prepositions in, on, under, and next to to identify novel creatures displayed on a screen (e.g., The wug is on the table), as well as their ability to later identify the creature without accompanying prepositions (e.g., Look at the wug). Children overall demonstrated understanding of all the prepositions but next to and were able to use their knowledge of prepositions to learn the associations between novel words and their intended referents, as shown by greater-than chance looks to the target referent when no prepositional phrase was provided.  相似文献

The purpose of this paper is to describe how to establish and maintain a low-cost zebrafish facility that can be used for both teaching and research purposes. The cost of the facility ranges from about 250 to250 to 1,000, depending on the size of the facility and the experiments that will be conducted. The facility plan presented here also has the advantage that it can be disassembled so that it need not function year-round. A detailed list of supplies and materials is provided, along with detailed instructions on how to set up and maintain the adult and breeding portions of the facility. Finally, there is discussion of some of the general uses of a zebrafish facility, including a variety of procedures that are currently being used in behavioral research with this species.  相似文献

This article provides an annotated summary of 26 different procedures potentially useful in analyzing group therapy process, and includes an overview of therapeutic themes, research issues and clinical implications. The goal is to familiarize clinicians and researchers with the range of standardized and semistandardized procedures available for studying group interactions that have appeared in the literature during the past several decades. The authors concentrate on observer rating systems and do not systematically review self-report instruments. It is argued that the application of objective rating systems may foster greater understanding of group therapeutic interactions than is generally possible through normal clinical observations.  相似文献

Interaction analysis has become a standard tool for process-oriented research. Although now a researcher has a choice of instruments, the majority of these are based on the same concept of communication: the sender–receiver model. Communication is treated as a discrete and encoded process that progresses uniformly in time. We critically discuss these assumptions and the limits they put on communication research. It is asserted that instruments for interaction analysis based on the sender–receiver model restrict themselves to the more superficial levels of interaction and are unable to register the more significant events. Therefore they cannot account for a very essential feature of the communication process, namely the creation of meaning. Alternative options are discussed.  相似文献

This meta-analysis includes studies concerning the relationships between emotional intelligence (EI) and subjective well-being (SWB). A total of 25 studies with 77 effect sizes and a combined sample of 8520 participants were found. The results provided evidence of a positive significant relationship between EI and SWB (? = 0.32). This relationship was found to be higher in studies using self-report mixed EI instruments (? = 0.38), than with in studies using self-report ability EI instruments (? = 0.32) and performance-based ability EI instruments (? = 0.22). When examining EI measures, there was a larger association between EI and the cognitive component of SWB (? = 0.35) than with the affective component (? = 0.29). There is a need for further research with other evaluation methods to achieve a better understanding of the relationship between EI and SWB.  相似文献

This research poses 2 applied questions: How large are racial group differences on personality scales and are these differences likely to cause adverse impact in personnel selection? We examined the extent to which racial groups differ across Big 5 personality factors and facets. Large‐scale, quantitative estimates based on over 700 effect sizes were meta‐analytically summarized. Multiple personality instruments and understudied racial groups, particularly Asian Americans and American Indians, were included in the meta‐analyses. Most group comparisons and personality scales yielded negligible differences and are not likely to cause adverse impact in selection. However, facet‐level analyses produced different d‐values, with some group comparisons showing moderate differences, suggesting that the use of personality measures in selection does not uniformly circumvent adverse impact concerns. The veracity of this conclusion depends on (a) the particular trait in question, (b) the composition of the applicant pool (i.e., which groups are to be compared with one another), (c) the effect size (i.e., d‐value), and (d) the selection ratio. For practitioners, we present a quantitatively informed summary of when and where to expect adverse impact to result from personality measures used in personnel selection.  相似文献

A maximum likelihood approach is described for estimating the validity of a test (x) as a predictor of a criterion variable (y) when there are both missing and censoredy scores present in the data set. The missing data are due to selection on a latent variable (y s ) which may be conditionally related toy givenx. Thus, the missing data may not be missing random. The censoring process in due to the presence of a floor or ceiling effect. The maximum likelihood estimates are constructed using the EM algorithm. The entire analysis is demonstrated in terms of hypothetical data sets.  相似文献

The purpose of this study was to examine the quality of quantitative articles published in the Journal of Counseling & Development. Quality concerns arose in regard to omissions of psychometric information of instruments, effect sizes, and statistical power. Type VI and II errors were found. Strengths included stated research questions and appropriateness of analyses. Implications of these results are provided.  相似文献
