To provide further information about the construct validities of the Beck Youth Inventories of Emotional and Social Impairment, these inventories were administered to 35 female and 65 male outpatients whose ages ranged from 7 to 12 years and who were diagnosed with various psychiatric disorders. The Children's Depression Inventory was also administered, and the children were rated by a parent with the Conners' Parent Rating Scale-Revised: Short Form. The scores on the former inventory were more positively correlated with the scores on the Beck Youth Depression Inventory (r =.81, p<.001) than with scores on the four other Beck Youth Inventories, and those on the Conners Oppositional scale were comparably correlated with the scores on the Beck Youth Disruptive Behavior (r=.49, p<.001) and Anger (r=.41, p<.001) Inventories. These latter correlations were higher than those for scores on the Oppositional scale with the scores on the three other Beck scales. 相似文献

The rapid growth of the Internet provides a wealth of new research opportunities for psychologists. Internet data collection methods, with a focus on self-report questionnaires from self-selected samples, are evaluated and compared with traditional paper-and-pencil methods. Six preconceptions about Internet samples and data quality are evaluated by comparing a new large Internet sample (N = 361,703) with a set of 510 published traditional samples. Internet samples are shown to be relatively diverse with respect to gender, socioeconomic status, geographic region, and age. Moreover, Internet findings generalize across presentation formats, are not adversely affected by nonserious or repeat responders, and are consistent with findings from traditional methods. It is concluded that Internet methods can contribute to many areas of psychology. 相似文献

Development of personality in early and middle adulthood: set like plaster or persistent change? 总被引:1,自引:0,他引:1

Different theories make different predictions about how mean levels of personality traits change in adulthood. The biological view of the Five-factor theory proposes the plaster hypothesis: All personality traits stop changing by age 30. In contrast, contextualist perspectives propose that changes should be more varied and should persist throughout adulthood. This study compared these perspectives in a large (N = 132,515) sample of adults aged 21-60 who completed a Big Five personality measure on the Internet. Conscientiousness and Agreeableness increased throughout early and middle adulthood at varying rates; Neuroticism declined among women but did not change among men. The variety in patterns of change suggests that the Big Five traits are complex phenomena subject to a variety of developmental influences. 相似文献

This study was designed to ascertain the level of hostility in educated unemployed youth (N = 150) as against employed youth (N = 150) at micro level by employing an Indian adaptation of the Buss-Durkee Hostility Scale. Results of statistical comparison revealed a significant difference between the two groups in terms of hostility and its various dimensions barring indirect aggression, negativism, and verbal aggression. However, both the groups tended to have a moderate amount of hostility and its dimensions. The results further showed the relative standing of the two groups on the dimensions of hostility, positing the job-seekers as possessing a high sense of guilt and low indirect aggression, and the employed youth, being high on irritability, and, like their counterparts, low on indirect aggression. Also, the study indicated a correlation among the dimensions of hostility with one another and with the total scale scores. 相似文献

Researchers in the field of conjoint analysis know the index-of-fit values worsen as the judgmental error of evaluation increases. This simulation study provides guidelines on the goodness of fit based on distribution of index-of-fit for different conjoint analysis designs. The study design included the following factors: number of profiles, number of attributes, algorithm used and judgmental model used. Critical values are provided for deciding the statistical significance of conjoint analysis results. Using these cumulative distributions, the power of the test used to reject the null hypothesis of random ranking is calculated. The test is found to be quite powerful except for the case of very small residual degrees of freedom.The authors thank the editor, the three reviewers and Ellen Foxman for helpful comments on the paper.

It has been suggested that mild fear may evoke rather than inhibit exploratory responses in rats. The relationship between conditioned fear and exploratory behaviour was analysed in three experiments and there was no evidence that mild fear increased exploration. Conditioned fear was found to be under relatively precise stimulus control and its magnitude was related to the intensities and durations of the unconditioned stimulus, inescapable electric shock. 相似文献

Ninety elementary school teachers, grades 2–6, in two school districts in Ohio were interviewed to obtain information on how they used the results of group IQ tests. Twenty-seven of 90 teachers (30%) reported making “little or no use” of the test scores. Most of these teachers presumably had more faith in their own tools and observations than in the IQ test scores. However, 76 of 90 teachers (84%, including the ones who made little use of the test scores) stated that they used the test scores for one or more purposes. The four most frequently mentioned uses were: (a) “for discussion in parent conferences” (51%); (b) “to know a student's potential and/or determine ability-motivation discrepancy” (42%); (c) “to plan instruction” (39.5%) and (d) “for referral purposes” (29%). The instructional strategies mentioned by the teachers varied and were categorized into 21 categories. 相似文献

This paper highlights the neuropsychological sequelae of posteroventral pallidotomy (PVP) and deep brain stimulation (DBS) of the subthalamic nucleus (STN) and the internal segment of the globus pallidus (GPi) at 3/6 months postoperatively. Results are based on our extensive experience with PVP and our preliminary observations with DBS. Patients with borderline cognitive or psychiatric functioning risk postoperative decompensation. Nonlateralizing attentional and hemisphere-specific impairments of frontostriatal cognitive functions followed unilateral PVP. "Frontal" behavioral dyscontrol was observed in approximately 25% of patients. Three cases of staged bilateral PVP suggest that premorbid factors may predict outcome, although lesion size and location are also critical. Older patients are at risk for significant cognitive and behavioral decline after bilateral STN DBS, while GPi DBS may be safer. 相似文献
