Questionnaires for measuring patients' feelings or beliefs are commonly used in clinical settings for diagnostic purposes, clinical decision making, or treatment evaluation. Raw scores of a patient can be evaluated by comparing them with norms based on a reference population. Using the Pain Cognition List (PCL-2003) as an example, this article shows how clinical questionnaires can be normed with multiple regression of raw scores on demographic and other patient variables. Compared with traditional norm tables for subgroups based on age or gender, this approach offers 2 advantages. First, multiple regression allows determination of which patient variables are relevant to the norming and which are not (validity). Second, by using information from the entire sample, multiple regression leads to continuous and more stable norms for any subgroup defined in terms of prognostic variables (reliability).  相似文献

A simple model for fluctuating interresponse times is developed and studied. It involves a mechanism that generates regularly spaced excitations, each of which can trigger off a response after a random delay. The excitations are not observable, but their periodicity is reflected in a regular patterning of responses. The probability distribution of the time between responses is derived and its properties are analyzed. Several limiting cases are also examined.This paper was completed while the writer was a visiting summer scientist at the Lincoln Laboratory, Lexington, Mass.  相似文献

Recent changes in the demographic structures of industrialized nations pose a potentially serious threat to work organizations in terms of their ability to attract and retain high calibre personnel. Specifically, the number of young people in their late teens and early-to-mid twenties is on the decline at the present time, coupled with a long-term recession, thus posing a dilemma for organizations concerned to develop and maintain a viable workforce. This article reports the findings of a three-country comparative study, conducted in The Netherlands, France and the United Kingdom, designed to investigate the extent to which graduate employers are aware of current demographic trends in the labour market and what HRM policies they are instituting, given this context. The findings reveal considerable levels of ignorance across all three countries, suggesting that attempts by various Government bodies, employers' organizations, professional associations and academics to draw attention to the potentially serious consquences of inadequate planning and future skill provision have largely failed. The results indicate that many organizations are engaging in human resource strategies which are not well suited to meeting the challenges of the 1990s.  相似文献

Multivariate information transmission   总被引:8,自引:0,他引:8  
McGill  William J. 《Psychometrika》1954,19(2):97-116
A multivariate analysis based on transmitted information is presented. It is shown that sample transmitted information provides a simple method for measuring and testing association in multi-dimensional contingency tables. Relations with analysis of variance are pointed out, and statistical tests are described.This work was supported in part by the Air Force Human Factors Operations Research Laboratories, and in part jointly by the Army, Navy, and Air Force under contract with the Massachusetts Institute of Technology.Several of the indices and tests discussed in this paper have been developed independently by J. E. Keith Smith (11) at the University of Michigan, and by W. R. Garner at Johns Hopkins University.  相似文献

Romanians suffered incredible deprivations of every sort during the decades of Communist dictatorship. Most of the country’s 1,000 psychiatrists, and most of their patients, were victimized by the political system. A few psychiatrists actively engaged in practices amounting to torture. Many, however, became willing or unwilling participants in the political abuse of their profession. Such political abuses were fostered by abusive legislation and abusive law enforcement by the secret police. Abuses included: mass detentions in psychiatric hospitals of dissidents and political undesirables; abusive interpretation of the laws in detaining persons not suffering from mental illness; false, politically motivated diagnoses and treatment; and detention in secret facilities.  相似文献

Association of socially demanding kin relations, mother’s emotional support, behavioral control/monitoring, family organization and psychological control with adolescent’s internalizing and externalizing problems were assessed in 200 economically disadvantaged, African American mothers and adolescents. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s internalizing problems. Demanding kin relations also moderated the association of control/monitoring, family organization, and psychological control, with internalizing. For mothers with more demanding kin relations, increased control/monitoring was associated with increased adolescent internalizing. In comparison, increased control/monitoring was associated with decreased adolescent internalizing for mothers with less demanding kin relations. Negative association of family organization with internalizing was more apparent for mothers with more compared to less demanding kin relations. Positive association of mother’s psychological control with internalizing was more apparent for mothers with more compared to less socially demanding kin relations. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s externalizing problems. Mother’s emotional support and family organization were negatively associated with externalizing. Also, negative association of family organization with externalizing was more apparent for families with more compared to less demanding kin relations. The need for research on the factors associated with negative relation with kin was discussed.  相似文献
