Kelley's formula as a basis for the assessment of reliable change

In the literature on the measurement of change,reliable change is usually determined by means of a confidence interval around an observed value of a statistic that estimates thetrue change. In recent literature on the efficacy of psychotherapies, attention has been particularly directed at the improvement of the estimation of the true change. Reliable Change Indices, incorporating thereliability-weighted measure of individual change, also known as Kelley's formula, have been proposed. According to current practice, these indices are defined as the ratio of such an estimator and an intuitively appealing criterion and then regarded as standard normally distributed statistics. However, because the authors fail to adopt an adequate standard error of the estimator, the statistical properties of their indices are unclear. In this article, it is shown that this can lead to paradoxical conclusions. The adjusted standard error is derived.     

计算机模拟动态心理测验

本文通过对心理测验的回顾与计算机模拟文献综合,把传统的纸笔测验与动态心理测验相比较,认为动态心理测验具有目标性、过程性与情境性三个特点,能够适应动态复杂的环境与群体作业任务,并且能够对阶段性的问题作出考察,具有传统的纸笔测验所不具备的优点.同时也提出,计算机模拟测验要更加注意外部效度与构思效度,注意计算机与人的交互作用的局限,才能够避免实验室实验的缺点,达到良好的模拟.     

A Prospective Longitudinal Study of High School Dropouts Examining Multiple Predictors Across Development

Prior studies report a variety of demographic, school, individual, and family characteristics that are related to high school drop out. This study utilizes data from a 19-year prospective longitudinal study of “at-risk” children to explore multiple predictors of high school dropouts across development. The proposed model of dropping out emphasizes the importance of the early home environment and the quality of early caregiving influencing subsequent development. The results of this study demonstrate the association of the early home environment, the quality of early caregiving, socioeconomic status, IQ, behavior problems, academic achievement, peer relations, and parent involvement with dropping out of high school at age 19. These results are consistent with the view of dropping out as a dynamic developmental process that begins before children enter elementary school. Psychosocial variables prior to school entry predicted dropping out with power equal to later IQ and school achievement test scores. In our efforts to better understand processes influencing dropping out prior to high school graduation, early developmental features warrant further emphasis.     

青春期情感自主性与学业成绩相关研究

本研究采用斯腾伯格和斯尔弗伯格编制的情感自主性量表 (EmotionalAutonomyScale)研究青春期情感自主性与学业成绩之间的关系。研究结果表明 :1.青春期表现出较为明显的情感自主性 ;2 .情感自主性对学业成绩的影响呈显著性水平 ;3.青春期情感自主性与学业成绩呈现相关关系。父母形象的非理想化与学业成绩成正相关 ,即父母的非理想化程度越高 ,学业成绩越差 ;而个体化与学业成绩成负相关 ,即个体化程度越高 ,学业成绩越差。 4 .青春期情感自主性存在明显的性别差异 ,女生的得分明显高于男生     

Hostility in fantasy: A further test of the hypoglycemia-aggression hypothesis

In a recent investigation carried out among the Qolla Indians of Peru, Bolton (1973a) tested the hypothesis that hypoglycemia tends to produce high levels of individual aggressiveness. Glycemic condition was determined by the readings on a 4-hour glucose tolerance test performed on a sample of 54 adult males. Key informants then ranked these subjects on overt aggressiveness. A correlational analysis of the data supported the hypothesis that moderately hypoglycemic subjects would be more aggressive than the normoglycemic subjects. The present paper responds to questions raised about this study and describes the results of an additional test of the hypoglycemia-aggression hypothesis. The dependent variable in this follow-up study is fantasy aggression. Aggression scores were derived from Sentence Completion Test protocols for the same sample of subjects used in the first study. The results indicate a significant correlation between glycemic condition and aggression scores (Biserial, 0.57), thus providing further confirmation of the hypoglycemia-aggression hypothesis.     

初中生学业自我效能、学习动机与学业成绩的关系

本研究使用学业自我效能量表和学习动机量表对初中生进行测量 ,并对测量结果与学业成绩间的关系进行了分析。结果发现 :学生学业自我效能、学习动机和性别是学业成绩的良好预测变量源 ,其中以学业自我效能的效应最为明显 ;学习动机与学业成绩之间并非单纯的线性关系。

情景判断测验的开发程序、构思效度及研究趋势

章详细介绍情景判断测验开发的一般程序,对情景判断测验的多种形式和记分方法进行了总结和比较。同时,从情景判断测验的结果与认知能力、个性和工作经验等关系的角度出发,分析了情景判断测验的构思效度,认为情景判断测验测量的是多维构思。文章最后认为,需要从与其他构思的关系、测评指定构思、影响效度的因素以及跨文化比较等四个方面对情景判断测验开展进一步研究。

基于CTT的锚测验非等组设计中四种等值方法的比较研究

采用锚测验非等组设计的数据收集方案,对4种基于经典测量理论的等值方法进行了比较研究。研究数据取自TIMSS1999数据库,兼用等值标准误和交叉验证方法作为各等值方法比较的检验标准,利用CIPE程序对实验数据进行分析。研究结果表明,针对本研究所设置的等值情境,线性等值优于等百分位等值,其中Tucker线性方法比Levine观察分数线性方法更好一些,Braun-Holland线性方法不宜采用,频数估计等百分位方法等值误差较大,亦不足取。
