Hypochondriasis is a debilitating condition in which patients are persistently preoccupied with the possibility of being seriously ill. Its is a costly problem for the health care system whose treatment has not received systematic attention until recently. Although based on few controlled studies, results indicated that various brief cognitive-behavioral techniques produce significant changes in illness fears and attitudes. A list of therapeutic questions that require further study is presented and some indications for both therapists and patients are given.  相似文献

Human performance in cognitive testing and experimental psychology is expressed in terms of response speed and accuracy. Data analysis is often limited to either speed or accuracy, and/or to crude summary measures like mean response time (RT) or the percentage correct responses. This paper proposes the use of mixed regression for the psychometric modeling of response speed and accuracy in testing and experiments. Mixed logistic regression of response accuracy extends logistic item response theory modeling to multidimensional models with covariates and interactions. Mixed linear regression of response time extends mixed ANOVA to unbalanced designs with covariates and heterogeneity of variance. Related to mixed regression is conditional regression, which requires no normality assumption, but is limited to unidimensional models. Mixed and conditional methods are both applied to an experimental study of mental rotation. Univariate and bivariate analyzes show how within-subject correlation between response and RT can be distinguished from between-subject correlation, and how latent traits can be detected, given careful item design or content analysis. It is concluded that both response and RT must be recorded in cognitive testing, and that mixed regression is a versatile method for analyzing test data.I am grateful to Rogier Donders for putting his data at my disposal.  相似文献

This article articulates joint priorities for the fields of prevention science and community psychology. These priorities are intended to address issues raised by the frequent observation of natural tensions between community practitioners and scientists. The first priority is to expand the knowledge base on practitioner–scientist partnerships, particularly on factors associated with positive outcomes within communities. To further articulate this priority, the paper first discusses the rapid growth in community-based partnerships and the emergent research on them. Next described is an illustrative research project on a partnership model that links state university extension and public school delivery systems. The article then turns to the second, related priority of future capacity-building for diffusion of effective partnership-based interventions to achieve larger-scale health and well-being across communities. It outlines two salient tasks: clarification of a conceptual framework and the formulation of a comprehensive capacity-building strategy for diffusion. The comprehensive strategy would require careful attention to the expansion of networks of effective partnerships, partnership-based research agendas, and requisite policy-making.  相似文献

We examined cross-sectional and lagged effects of sexual harassment (SH) and generalized workplace harassment (GWH) on incidence of self-reported illness, injury, or assault in a sample of over 1,500 university employees. SH and GWH, but not other job stressors, were related to increased odds of illness, injury, or assault. This was true when SH, GWH, and illness, injury, or assault were measured at the same time point, as well as when SH and GWH were measured in year prior to illness, injury, or assault.The data presented here are part of an ongoing longitudinal study of workplace harassment conducted at the Department of Psychiatry of the University of Illinois at Chicago. This research was supported by the National Institute on Alcohol Abuse and Alcoholism (grants AA09989 and AA13332). Portions of this paper were presented at the annual meeting of the Society for Industrial and Organizational Psychology, April 2004, Chicago, Illinois. The data were collected by the Survey Research Laboratory at the University of Illinois at Chicago.  相似文献

Rates of both intimate partner violence and poor health are high among low-income women This paper examines relationships among abuse, health, and employment stability using data from a 3-year study of over 1000 female welfare recipients in Illinois. Results demonstrate the importance of accounting for both recency and chronicity of intimate partner violence and understanding the mediational role of health in the relationship between intimate partner violence and employment. Chronic intimate partner violence is associated with poor health, whereas recent intimate partner violence is associated with unstable employment. Mediations analyses suggest that health does not mediate the effects of abuse on employment stability over a 3-year period.  相似文献

The Living with Asthma Questionnaire (LWAQ) and the Asthma Bother Profile (ABP) were translated into Norwegian using conventional back translation procedures, and completed by 30 asthma outpatients and 30 asthma patients admitted to inpatient rehabilitation. Reliability (Cronbach's alpha and retest-reliability) was shown to be good for both scales. Validity was established by showing significantly poorer health in the rehabilitation sample, and correlations with state and trait anxiety. The Norwegian translations are reliable and valid versions of the original questionnaires.  相似文献

Delayed matching to complex, two-picture samples (e.g., cat-dog) may be improved when the samples occasion differential verbal behavior. In Experiment 1, individuals with mental retardation matched picture comparisons to identical single-picture samples or to two-picture samples, one of which was identical to a comparison. Accuracy scores were typically high on single-picture trials under both simultaneous and delayed matching conditions. Scores on two-picture trials were also high during the simultaneous condition but were lower during the delay condition. However, scores improved on delayed two-picture trials when each of the sample pictures was named aloud before comparison responding. Experiment 2 replicated these results with preschoolers with typical development and a youth with mental retardation. Sample naming also improved the preschoolers' matching when the samples were pairs of spoken names and the correct comparison picture matched one of the names. Collectively, the participants could produce the verbal behavior that might have improved performance, but typically did not do so unless the procedure required it. The success of the naming intervention recommends it for improving the observing and remembering of multiple elements of complex instructional stimuli.  相似文献

The study of equivalence relations exhibited by individuals with mental retardation and language limitations holds the promise of providing information of both theoretical and practical significance. We reviewed the equivalence literature with this population, defined in terms of subjects having moderate, severe, or profound mental retardation. The literature includes 55 such individuals, most of whom showed positive outcomes on equivalence tests. The results to date suggest that naming skills are not necessary for positive equivalence test outcomes. Thus far, however, relatively few subjects with minimal language have been studied. Moreover, we suggest that the scientific contributions of studies in this area would be enhanced with better documentation of language skills and other subject characteristics. With recent advances in laboratory procedures for establishing the baseline performances necessary for equivalence tests, this research area is poised for rapid growth.  相似文献

The economy is one of the most important social environments that affect well-being, and community psychologists have long studied the social costs of one key economic stressor—job loss. But economically inadequate employment has received much less research attention than unemployment in regard to mental health effects. This paper contrasts these two literatures and considers factors that might account for their differential growth including actual rates of unemployment and underemployment. Recent panel studies offer no support for another possible basis for this differential growth—the assumption that inadequate employment is more like adequate employment than unemployment. Implications of a paradigm shift from a dichotomous perspective (employment vs. unemployment) to a continuum perspective with variations of both unemployment and employment are discussed for research and prevention. Another implication is the need to expand standard labor force statistics to reflect better the degree of underemployment.  相似文献
