Several factor analyses of the Millon Clinical Multiaxial Inventory (MCMI) have resulted in very similar solutions. Interpretation of this consistency is hampered by the fact that the 20 scales of the inventory share items. Overlapping items cause the scales to be linearly dependent and may create structure in the interscale correlation matrix which is separate from the subject response patterns. A factor analysis was performed on the matrix of item-overlap coefficients which describes the underlying artifactual structure of the instrument. Data from two new subject samples were factor analyzed and compared to previously published studies. Similarity coefficients among factors across studies were calculated. 相似文献

In this archival study the authors sought to determine the relationship, if any, between counseling outcomes and the topical focus in career counseling. Twenty-two counselors saw 46 adult clients at a community-based clinic for an average of eight sessions. Counseling outcome and topical focus (the extent to which the actual content of counseling sessions reflected relatively more vocationally or personally focused topics) were assessed from follow-up questionnaires to former career clients and from trained raters' evaluations of the counselors' written progress notes. Results showed that, from the counselors' perspective, outcomes were better when the focus of the sessions was relatively more vocational than personal and when relatively more interviews were held. Client satisfaction, on the other hand, was predictable only from the counselor's level of experience. Satisfaction with occupational status was not associated with any of the client, counselor, or treatment factors. Discussion focuses on the contribution of the results to career counseling practice and on the feasibility and validity of retrospective, archival research. 相似文献

There appears to be a strong relationship between mass media portrayals of violence and real-life violence itself. This article
reviews the available literature on the effects of media treatment of sports violence; analyzes the theoretical explanations
for this treatment; and makes proposals on how the problems of both sports violence and its media coverage may be remedied,
with a particular focus on amateur hockey in Canada. 相似文献

This paper describes an amplifier for an electroencephalograph with gain of 1×104 to 1×106 and made entirely of commercially available IC components. The two-stage amplifier has a preamplifier stage with fixed gain of 1000, and a second stage with variable gain from 1 to 100. The final stage, an anti-aliasing filter, adds a gain of 10 to the signal. The circuit has high common mode rejection, low input bias current, very low noise characteristics, low offset voltages, and offset nulling capability built into the circuit. 相似文献

A unique relationship exists between physicians and philosophers — one that expands on the constructive potential of the liaison between physicians and, for example, theologians, on the one hand, or, social workers on the other. This liaison should focus in the scientific aspects of medicine, not just the ethical aspects. Philosophers can provide physicians with a perspective on both the philosophy and the history of medicine through the ages — a sense of how medicine has adapted to the social cultural and ethical needs of each period. This perspective, while emphasizing medicine asscience, should not be limited to matters of methodology, or to criteria for distinguishing science from other intellectual pursuits, but should be concerned also with the history, sociology and politics of science. Both physicians and philosophers stand to gain from a strengthening of their active liaison now as never before; but most of all, the public will be the beneficiary. 相似文献

Fear of Success (FOS) was originally conceived as a unidimensional motive. However, there is both theoretical and empirical
support for the hypothesis that FOS is multidimensional. We factor analyzed the responses of 236 undergraduates to twenty-oneConcern Over the Negative Consequences of Success items and found four factors. Our four factors show considerable overlap with dimensions based on theoretical accounts of
FOS etiology as well as with the factor structures obtained from two other factor analytic studies. Thus, there is converging
evidence that FOS is multidimensional. The relationship between multidimensional FOS and a multidimensional approach to achievement
motivation is discussed. 相似文献
