This paper describes four studies on self-reported problems in 2,243 adolescent males and females, 12 to 17 years of age. In Study 1, principal-axis factoring of 102 items covering 11 problem domains revealed six factors comprising 49.5% of the variance. Study 2 used confirmatory factor analysis of a 64-item reduced set on a new sample of 408 adolescents. Goodness-of-fit indicators suggested that the six-factor model had excellent fit to the data. Study 3 used data from the 2,157 adolescents used in the first two studies. Coefficient alphas ranged from .83 to .92. Median test-retest reliability for the six factors was .86. There was a consistent structure of the correlation matrix across age and gender. Study 4 was a study of criterion validity, using an additional sample of 86 children with attention-deficit hyperactivity disorder (ADHD). Sensitivity and specificity were high, with an overall diagnostic efficiency of 83%. This new self-report scale, the Conners/Wells Adolescent Self-Report of Symptoms (CASS), may provide a useful component of a multimodal assessment of adolescent psychopathology.  相似文献

The relations between family support, family conflict, and adolescent depressive symptomatology were examined longitudinally in a sample of 231 female and 189 male adolescents and their mothers. Structural equation models revealed that less supportive and more con-flictual family environments were associated with greater depressive symptomatology both concurrently and prospectively over a 1-year period. Conversely, adolescent depressive symptomatology did not predict deterioration in family relationships. Depressive symptomatology and, to a greater extent, family characteristics showed high levels of stability over the 1-year period. Counter to our expectations, the relations between family variables and depressive symptomatology were similar for boys and girls. The results suggest that the quality of family interactions is relevant for understanding the development of depressive symptoms in adolescents.  相似文献

The selectivity hypothesis of Meyers-Levy (1989) proposes that cognitive sex differences reflect underlying differences in information processing between males and females. Males are considered to be more likely to organize information in a self-related manner, whereas females are more likely to adopt a comprehensive approach to information processing. We tested this hypothesis in children (10–15 years) and adults using recognition memory tasks. Tests were devised which employed male-oriented objects, female oriented objects, or random objects. In both the child and adult samples, females performed significantly better than males on tests using random and female-oriented objects. Males performed at the level of females only when tested for recognition of male-oriented objects. These results demonstrate that this sex difference is present prior to puberty and support the concept of sex differences in information processing.  相似文献

Since the terms of the health policy debate in the United States and Canada are largely supplied by biomedicine, the current “crisis” in health care is, in part, a product of biomedical rhetoric. In this essay, three metaphors widely identified as being associated with biomedicine—the body is a machine, medicine is war,and medicine is a business—are examined with a view to the ways in which they influence the health policy debate, not only with respect to outcomes, but also with respect to what can be argued at all. The essay proposes that biomedical language itself be foregrounded as the constitutive material of public discourse on health policy.  相似文献

Our focus in this study was the observed gap between informed awareness and the intention to act. We used elements of social cognitive theory to develop a theoretical model of six psychosocial factors hypothesized to influence the intention to adopt healthy eating behaviors. Survey data from 490 white-collar employees were analyzed using a Linear Structural Relations (LISREL) program and a stacked model. The overall fit of the model to one half of the data was excellent, x2 (6, 237) = 3.79, p= 0.71, and the model was successfully replicated with the second half of the data x2 (28, 249) = 28.68, p= 0.43. Our model suggests that self-efficacy expectations (a) partially depend on the perceived likelihood of an outcome; (b) act as a conduit for the effects of media, disincentives, and outcome expectancy; and (c) have powerful direct influences on intentions. As expected, outcome expectancy adds little to the prediction of intentions.  相似文献

Specificity designs in psychopathology research are used to examine whether a variable is unique to a given disorder. When nonspecificity is observed, it typically is assumed that the variable in question is not a cause of the disorder, but is instead a nonspecific consequence of general psychopathology. Such reasoning is flawed, however, because it fails to distinguish between testing a particular causal model containing the variable versus testing the causal status of the particular variable within the model. A variable may be nonspecific, but still causal, if it is one of several multiple interacting causes or if a nosological error has been made. A recognition of these complexities has implications for the nature of the psychopathology control group selected.  相似文献

This study sought to determine whether recognition hypermnesia (unforgetting) might be obtained over time with repeated testing of recognition memory. Four types of stimuli were investigated: pictures or words (captions) from configured (funny) or non-configured (non-funny) cartoons. Three recognition tests, each comprising the same stimulus and distractor items, were successively administered after the presentation of a large set of captioned cartoons. Silent think intervals of 5 min were interpolated between recognition tests. Recognition hypermnesia, measured by increasing d' estimates of accessible recognition memory, was obtained with the pictures from configured (funny) cartoons but not with any of the other groups.  相似文献

The case of a 57-year-old congenitally deaf man who suffered a cerebral vascular accident is presented. Resultant symptomatology included right hemiplegia and aphasia. The authors' findings and conclusions concur with a small, but slowly growing, body of literature which suggests that the fundamental linguistic processes are the same for the congenitally deaf and for the normal hearing population.  相似文献

Predictions made from the learned-helplessness model received support in three experiments. The effects of response-outcome independence, as well as immunization and reversibility of such effects were demonstrated with human subjects. It was also demonstrated that differences in locus of control, sex and attribution, influenced those results. Furthermore, the effects of modeling and the use of cognitive tasks for both pretreatment and reversibility were examined.  相似文献
