The Test of Self-Conscious Affect (TOSCA) is a well-established scenario-based questionnaire assessing self-conscious emotions, such as shame and guilt, which have been shown to be differentially associated with a variety of functional, motivational, behavioral and health outcomes. The aim of this study was to evaluate the psychometric properties and internal structure of a Swedish version of TOSCA in a sample of 361 healthy adults. The psychometric properties and internal consistency of the Swedish version were at level with the original US TOSCA version for shame, guilt and detachment. The internal structure of the Swedish version was acceptable for shame, guilt and detachment but contained shortcomings in assessment of externalization.  相似文献

Research examining links between personality and interest have typically focused on links between measures of the five factor model and Holland’s RIASEC types. However, the five factor model of personality can be divided in to a larger set of narrow domain personality scales measuring facets of the ‘big five’ traits. Research in a number of fields indicates that facet scales are effective for clarifying the relationship between personality and other broad constructs, including academic achievement, job performance, stress and coping, and achievement motivation. In the present study links between personality facets and the RIASEC model were examined using property vector fitting. Obtained results are consistent with previous research suggesting that the use of facet-level personality measures can clarify relations between personality and other constructs, and provides new information linking personality facets and interests. The use of facet-level measures of personality expands the range of personality concepts that can be presented to individuals who are exploring career options.  相似文献

Claims have been made that grade appropriate curriculum-based measurement of reading (CBM-R) passages are of comparable difficulty and can be used interchangeably to monitor student progress. Empirical evidence to support claims of equivalence has been lacking. This research investigated the basis for making claims of equivalence. The use of readability statistics to justify passage equivalence was found to be lacking. Using a general measurement model for congeneric tests, CBM-R passages were found to measure a single latent factor with a high degree of reliability. However, evidence indicated that the raw scores, words read correctly per minute, across passages did not provide equivalent measurements. Statistical equating was investigated as an approach to overcome the lack of equivalence with promising results.  相似文献

复吸是药物成瘾的重要特征,应激是诱发复吸的因素之一。该文介绍了用于研究应激诱发复吸的动物恢复模型,阐述了涉及应激诱发复吸的神经生物学基础。大量研究结果表明,下丘脑外侧的终纹床核与杏仁核内的促肾上腺皮质激素释放因子和去甲肾上腺素是参与应激诱发复吸的重要神经递质。内侧前额叶皮层可能是介导应激、药物点燃及药物相关线索等各类因素诱发复吸的共同通路  相似文献

中学生思维风格结构及其测量   总被引:4,自引:1,他引:3  
赵俊华  张大均 《心理科学》2007,30(1):142-144
本研究在文献分析和开放调查的基础上,构建了中学生思维风格的理论结构,并据此编制了中学生思维风格量表。对测量结果进行探索性和验证性因素分析表明:思维风格是一个单一维度的整体-分析型结构,它包括两个呈两极连续性的整体和分析因素,可以用来说明复杂多样的具体思维风格类型。  相似文献

通过两个实验探讨主体因素差异对学习判断值及其孤立效应的影响。选取708名高一学生作为被试,男女各半。实验一考察主体对材料性质的觉知感差异对学习判断值及其孤立效应的影响,实验二考察主体对材料项目数的确定感差异对学习判断值及其孤立效应的影响。结果表明,提高主体对材料性质的觉知感,可以提高学习判断值,但并没有提高学习判断的孤立效应;而提高主体对材料项目数的确定感,不仅可以提高学习判断值,而且可以提高学习判断的孤立效应。  相似文献

Within contemporary psychology there is increasing interest in the role of religion on behaviour and psychological functioning. Such interest can be attested to by the growth in the number of pertinent books and articles that have been published and also the development of new self-report measures of religiosity. The Santa Clara Strength of Religious Faith Questionnaire is one such recently developed measure. It is a brief self-report measure comprising 10 items that were designed to measure strength of religious faith regardless of religious denomination or affiliation. Although Plante and Boccaccini (1997a, 1997b) have provided some preliminary evidence for the reliability and validity of the scale, the factor structure of the scale has not yet been examined. The aim of the present paper was to confirm the factor structure of the scale. The hypothesised one-factor model was tested using confirmatory factor analytic methods. Data from a sample of 106 Northern Irish undergraduate university students were examined using confirmatory factor analytic methods. A one-factor model was tested and accepted on the basis of fit statistics, therefore supporting the hypothesised unidimensional structure of the scale. The present results provide further evidence that the Santa Clara Strength of Religious Faith Questionnaire is psychometrically sound and therefore it can be recommended for further use by researchers interested in the construct of strength of religious faith.  相似文献
