This study examined sociodemographic, diagnostic, psychological, and episode-based variables in a sample of 130 psychiatric patients admitted to treatment at least twice in a 6-yr. period. Short length of initial hospitalization (r = -.30, p < .01) and younger age on initial admission (r = -.20, p < .05) were significantly correlated with frequent hospital admissions. Scores on four of the subscales of the WAIS-R were significantly correlated with readmission, confirming that patients who have fewer cognitive resources are at risk of frequent admissions. A multiple regression analysis combining variables to predict readmission accounted for only 12% of the common variance (r128 = .34, p < .01), however, indicating that a prediction equation with these variables has limited clinical utility. 相似文献

Signal-detection analysis of group decision making 总被引:1,自引:0,他引:1
How effectively can groups of people make yes-or-no decisions? To answer this question, we used signal-detection theory to model the behavior of groups of human participants in a visual detection task. The detection model specifies how performance depends on the group's size, the competence of the members, the correlation among members' judgments, the constraints on member interaction, and the group's decision rule. The model also allows specification of performance efficiency, which is a measure of how closely a group's performance matches the statistically optimal group. The performance of our groups was consistent with the theoretical predictions, but efficiency decreased as group size increased. This result was attributable to a decrease in the effort that members gave to their individual tasks rather than to an inefficiency in combining the information in the members' judgments. 相似文献

It is generally assumed that the latent trait is normally distributed in the population when estimating logistic item response theory (IRT) model parameters. This assumption requires that the latent trait be fully continuous and the population homogenous (i.e., not a mixture). When this normality assumption is violated, models are misspecified, and item and person parameter estimates are inaccurate. When normality cannot be assumed, it might be appropriate to consider alternative modeling approaches: (a) a zero-inflated mixture, (b) a log-logistic, (c) a Ramsay curve, or (d) a heteroskedastic-skew model. The first 2 models were developed to address modeling problems associated with so-called quasi-continuous or unipolar constructs, which apply only to a subset of the population, or are meaningful at one end of the continuum only. The second 2 models were developed to address non-normal latent trait distributions and violations of homogeneity of error variance, respectively. To introduce these alternative IRT models and illustrate their strengths and weaknesses, we performed real data application comparing results to those from a graded response model. We review both statistical and theoretical challenges in applying these models and choosing among them. Future applications of these and other alternative models (e.g., unfolding, diffusion) are needed to advance understanding about model choice in particular situations. 相似文献

The development of the Multicultural and Social Justice Counseling Competencies (Ratts, Singh, Nassar-McMillan, Butler, & McCullough, 2015) provides a framework to reflect upon previous scholarship and explore further approaches for methodological innovation in counseling. The author presents available counseling and interdisciplinary scholarship related to multicultural and social justice competency, identifies gaps and future research directions of that research, and proposes innovative strategies and methods for conducting rigorous multicultural and social justice research. Implications for preparing future counseling scholars are also included. 相似文献

OBJECTIVE: The objective of this study was to compare characteristics of smokers who did and did not report use of cessation aids as part of a tobacco control program in a military setting (n = 8994). DESIGN: The study is a longitudinal epidemiological study where the relationship between smoking status at follow-up and use of pharmacologic aids to quit smoking were assessed. MAIN OUTCOME MEASURES: Smoking cessation, post baseline use of cessation aids to quit smoking. RESULTS AND CONCLUSIONS: Individuals remaining abstinent were 70% less likely to have used NRT/pharmacological aids compared to those that relapsed. NRT/pharmacological aid users were more likely to report plans to smoke after military training, to have friends who smoke, and to accept a cigarette from a friend. NRT/pharmacological aid users were more likely to believe that using NRT was safer than smoking and to have engaged in harm reduction strategies. Our findings suggest that selection bias related to such characteristics may explain some of the discrepancies between effect sizes reported in efficacy compared to effectiveness studies of NRT and smoking outcomes currently reported in the literature. 相似文献

Increasing state legislation and media interest give the appearance of public support for parental responsibility laws; however, some national polls suggest otherwise. Based on disparate global and specific attitudes in other areas of the criminal justice literature, it was hypothesized that relatively weak global support for parental responsibility would be diminished even more if a specific juvenile was described. The current studies confirmed that participants were even less supportive of parental responsibility laws when a specific juvenile and his parents were described than they were when they answered questions about parents in general. 相似文献

This paper extends research on images of God, which prior researchers based mostly on national survey data, to a study of offenders in prison. We first explore whether the distribution of Froese and Bader’s (America’s four gods: What we say about god–& what that says about us, Oxford University Press, New York 2010) four images of God among prison inmates is similar to that in the general population. We then examine whether an inmate’s image of God is associated with the inmate’s worldviews: beliefs and attitudes toward the law, other inmates, moral responsibility, and ultimate meaning and purpose in life. Finally, we test whether an inmate’s belief in a forgiving God and religiousness explain the association. We analyzed data from a survey of 2249 inmates at America’s largest maximum-security prison, the Louisiana State Penitentiary. We found the distribution of God-images among inmates was the same as that in national samples in terms of rank order. As hypothesized, we also found inmates with an image of an engaged God tended to report lower levels of legal cynicism and sense of illegitimacy of punishment and higher levels of collective efficacy, existential belief, and moral responsibility than those with images of a disengaged God or no God. Finally, we found an inmate’s belief in a forgiving God and religiousness to mediate partly relationships between images of God and the inmate’s worldviews. 相似文献
