Abstract

One or two session psychotherapy has a long history, and well-known practitioners have made use of it. Favorable results have been reasonably well documented. Often it has been done out of necessity, less frequently because all were satisfied that it sufficed. Problems that lend themselves to one or two sessions are: psychological work which has already been done but for which affirmation is sought, requests for diagnostic evaluation, and less often but more challenging, intrapsychic conflict requiring uncovering work. Patient characteristics and therapist attitudes are discussed. For one or two sessions of treatment to occur the therapist must be alert to the possibility, must assess quickly when a case is in hand, set the process in motion, and determine a satisfactory stopping point. It is suggested that the college population lends itself especially well to one or two sessions of psychotherapy, not only from the standpoint of the limited resources of many student health services but also for the ego strengthening potential it provides.  相似文献

Christine Jorgensen's widely publicized sex reassignment surgery in 1952 brought transsexualism to worldwide attention and fostered medical interest in transsexualism. Joanne Meyerowitz has traced the history of Jorgensen's personal odyssey, the medical history of transsexualism, and the broader impact of transsexualism on United States culture. In this interview, Meyerowitz discusses how she came to this project and some of its theoretical and methodological challenges. Finally, she sets her historical work in the context of contemporary gender and transgender politics.  相似文献

In this paper, I first survey the ways in which bisexuality was understood by late 19th-century sexologists, by Freud and his followers, by Alfred Kinsey, and by contemporary social scientists and political activists. Then the three domains distinguished by Freud in which bisexuality is currently being examined are surveyed: biological bisexuality, psychological bisexuality (in terms of gender), and kinds of object choice. Particular areas of research that indicate how questions about bisexuality are currently being considered are mapped, for example, transsexualism. The final part of the paper is an inquiry into the ways in which objects are bisexual, a domain that has been neglected in the complex history of work on bisexuality.  相似文献

In a series of papers, Kshirsagar (1964, 1971) and McHenry and Kshirsagar (1977), factorize Wilks' A into a number of factors and find the independent null multivariate beta densities of these factors. These factors are the likelihood ratio test criteria for testing the goodness of fit of certain assigned discriminant functions or canonical variables either in the space of independent or dependent variables. Essentially the factors of Wilks' A are the factors of certain multivariate beta distributed matrix or its determinant. The Bartlett decomposition of the underlying multivariate beta distribution into independent factors determines the distribution of these factors. The present paper generalizes Kshirsagar's (1971) normal theory to the elliptically contoured model, and shows that his results are null robust for the elliptically contoured model.  相似文献

The results of several studies have established the validity of the SCOFF questionnaire (a 5-question screening tool for eating disorders), but researchers need to explore further replicability using the US version in the graduate school population. In this study, the authors asked 335 graduate students attending the Northwestern student health clinic on the Chicago campus to complete a written survey anonymously. A total of 305 (91%) patients completed the survey. The sensitivity and specificity for the SCOFF was 53.3% and 93.2%, respectively. This produced a PPV (the proportion who tested positive on the screen and actually had an eating disorder) of 66.7% and an NPV (the proportion of those who tested negative on the screen and actually did not have an eating disorder) of 88.7%. More than 80% of respondents were dissatisfied with their shape and weight, with over one third having a moderate to severe body image disturbance. The SCOFF is an easy instrument to administer that health care providers can use to screen for eating disorders in the primary care setting.  相似文献

A gamma regression model with an exponential link function for the means Is considered. Moment properties of the deviance statistics based on maximum likelihood and weighted least squares fits are used to define modified deviance statistics which provide alternative global goodness of fit tests. The null distribution properties of the deviances and modified deviances are compared with those of the approximating chi-square distribution and It is shown that the use of the modified deviances gives much better control over the significance levels of the tests.  相似文献
