This paper takes the results of Lindley and smith ( 1972 ) one step further, by finding the predictive distribution of an observation y* whose distribution is normal, and centred at A* 1θ1 We then apply this distribution to the case of prediction based on data obtained in one and two wau ANOVA situations. For Example, it turns out that for two way ANOVA with interaction, the predictive mean, (which we would use as the predictor) is a weighted combination of sample main effects and interaction effects  相似文献

An evaluation of the hypothesis that adolescent gamblers are biased toward the production of false positive responses proposed by Derevensky et al. was tested. The results of secondary analysis of available data supported the hypothesis for items on the South Oaks Gambling Screen and items from the DSM-IV screening instrument. The conclusions were presented as tentative in view of the modest sizes of the observed effects. A number of limitations to the analysis are also described.  相似文献

The aim of the present study was to translate the Homosexuality scale of the Trueblood Sexual Attitudes Questionnaire into the Italian language and to assess its factor structure and psychometric properties in Italian psychology students. The questionnaire was originally developed and validated in U.S. college students, and later in Turkish social work students, showing high internal consistency. It measures attitudes toward several sexual practices and behaviors, regarding self and others. Particularly, the Homosexuality scale measures attitudes toward different sexual and romantic practices with people of the same sex. A total of 199 Italian psychology students participated to the study, and they were administered the Italian translation of the scale. We applied exploratory factor analysis and confirmatory factor analysis. Results showed that the scale has high internal consistency, and that the original two-factor model accounting for attitudes toward self and others fits the data well. Implications for education and assessment in student populations are discussed.  相似文献

The present paper has three objectives. First, methods for comparing alternative tests for the purpose of replacement of one test with a second presumably superior test are described. Second, problems in the interpretation of the relevance of different diagnostic thresholds (thresholds of positivity) that define who is and who is not a disordered gambler are examined and a potential solution offered in the form of a common quantitative measure of the risk of being a disordered gambler. Third, alternative methodologies are described as potential solutions to the lack of a gold or reference standard in the evaluation of new tests.  相似文献

Much of the debate over how best to estimate the prevalence of problem gambling in the general population is driven by a number of misconceptions, misinterpretations, and questionable, sometimes erroneous assumptions. Among the latter is the failure to understand that what is being validated is not the test but the interpretation of test scores for a specific purpose. In addition there has been a lack of attention to defining the clinical and/or epidemiologic relevance of case definitions in terms of severity and other clinical attributes, a misunderstanding of how test values are interpreted when criterion thresholds or cut-off points are selected, and a failure to replicate the validation of criterion thresholds for defining cases of problem gambling. It is argued further that the distinction between dichotomy and continuum is a false choice, and any emphasis on overestimation is misdirected. Alternative methods for evaluating tests and estimating prevalence are described and a pragmatic empirical approach to the interpretation of prevalence estimates is recommended.  相似文献

Aging lesbian, gay, and bisexual (LGB) adults often differ from their heterosexual counterparts in their social network. This study examined a sample of 220 LGB adults over 50-years-old; most were White, well-educated, and employed. Social networks were used to predict physical and psychological well-being and lifestyle/risk. Respondents had on average 2.5 members in their social network; 56 percent had at least one close friend. Support from friends rather than family predicted higher mental quality of life and lower depression, anxiety, and internalized homophobia. Study participants functioned within normal ranges of most psychological measures. However, they had serious health risks due to alcohol consumption and obesity (inwomen). Findings add further evidence of the importance of friends in providing social support among LGB adults.  相似文献

This research examines the relative perception of gambling as a disease in the context of drug use/abuse, and other excessive behavior patterns, for example, workaholism. A sample of 144 adults provided subjective perceptions of disease status of 80 representative items drawn from the literature. A subset of these items represented the class of addictive diseases. These items were subjected to principal components analysis to reveal the presence of clusters or constellations of perceptually similar entities. Gambling was perceived to beless of a predicament (i.e., a potentially dangerous situation; Shaffer, 1987) than substance abuse or substance dependence, particularly if the substance was illicit, such as cocaine or heroin. Gambling was not perceived to be characterized by the underlying construct of dependence, a dimension associated with the abuse of illicit substances. Another analysis revealed that when gambling and substance abuse and dependence were perceived against ause of substances background, licit and illicit, gambling was more likely perceived as a permissible activity than a predicament which might lead to abuse and/or dependence. This same result characterizes the perceptions of alcohol use, cocaine use, chemical use, and heroin use. While individuals may recognize the potential danger of drug abuse, illicit drug use per se is not perceived to lead to drug abuse, dependence, or addiction as often portrayed by the government and media. Against a background of excessive behaviors, for example, workaholism, gambling emerged as more similar to these behaviors than abuse or use. The implications of these findings are discussed. The clinical implications of an epistemology of addictive disease were also discussed.Preparation of this article was supported, in part, by a contract (#2322905893) from the Massachusetts Department of Public Health.Special thanks are extended to Thomas Cummings, Sharon Stein and Norman Zinberg for their helpful comments on earlier drafts of this article.  相似文献

The concern that the South Oaks Gambling Screen (SOGS) and other screening tests have a relatively high rate of false positive errors which results in overestimation of the true prevalence in general population studies is shown to be unfounded. False positives are seen to be a necessary but not sufficient condition for overestimation. It is demonstrated that the proper research question is whether the sample prevalence estimator is biased, and, if so, in which direction. One solution to the problem of bias is shown to depend on the availability of estimates of the error rates of the test.  相似文献
