This paper presents a method of estimating a receiver operating characteristic (ROC) curve when the underlying diagnostic variable X is continuous and fully observed. The new method is based on modelling the probability of response given X , rather than the distribution of X given response. The method offers advantages in modelling flexibility and computational simplicity. The resulting ROC curve estimates are semi-parametric and can, in principle, take an infinite variety of shapes. Moreover, model selection can be based on standard methods within the binomial regression framework. Statistical accuracy of the curve estimate is provided by a simply implemented bootstrap approach. 相似文献

A fact-gathering, experimental game proved to be an effective instrument in the needs assessment phase of an adolescent sexuality educational program aimed at low-income females. The game ("Family Few"), which covered the topics of menstruation and reproduction, was played by 35 Black, Hispanic, and white females aged 13-16 years recruited from medical and psychiatric clinics in Miami, Florida. The goals of the game were to elicit terminology used by participants, identify and correct misconceptions and misinformation, and determine if learning could occur. Although 57% of participants reported prior exposure to formal sex education, misinformation about the need for activity curtailment during menstruation and the importance of early pregnancy detection was widespread. Group members believed they needed to restrict activities involving physical exercise, sexual relations, water, and cold during menses and were not likely to seek medical or family consultation regarding a missed period until the end of the 1st trimester of pregnancy. Also evident was a need for accurate information on the side effects, risk factors, benefits, and effectiveness of contraceptive methods. The group responses enabled the sex educators to prepare a culturally responsive, developmentally oriented curriculum for further work with disadvantaged female adolescents. The group process was ranked highly on the Likert Scale by these teenagers as an enjoyable, useful means of information dissemination and problem solving. 相似文献

This paper discusses the development of a children's rights‐based measure of participation and the findings from its use in a survey of 10‐ to 11‐year‐old children (n = 3773). The measure, which was developed in collaboration with a group of children, had a high reliability (Cronbach's alpha = 0.89). Findings suggest that children's positive experience of their participation rights is higher in school than in community, and higher for girls compared to boys. It is argued that involving children in the ‘measurement’ of their own lives has the potential to generate more authentic data on children's lived experiences. 相似文献

The purpose of this study is to explore the conflict between use and preservation in national parks policy as seen through
the mission statement of the National Parks Service. The histories of the national parks were qualitatively coded in order
to further explore this controversy, or what we have termed “mission rivalry”. 相似文献

Few measures parallel the robust depth offered in the existing multidimensional and ecologically informed theories of resilience. This study sought to evaluate the test–retest reliability, construct, and predictive validity of the individual, family, and community resilience resource profile (IFCR-R). The IFCR-R measures a family’s access to resilience resources and protective factors across multiple ecological levels. Confirmatory factor analysis was used with a sample of n?=?810 low-income families. And 159 families completed multiple time point measures for test–retest reliability and predictive validity evaluation. Results of this study support the proposed multidimensional ecological structure of the IFCR-R and found that the IFCR-R offers an acceptable test–retest reliability and predictive validity for outcomes of mental and physical health. 相似文献
