An exploration of body dissatisfaction and perceptions of Black and White girls enrolled in an intervention for overweight children

Silhouette measures are one approach to assessing body dissatisfaction in children, although little is known about their use among racially diverse, overweight girls seeking weight-loss treatment. This study assessed racial differences in body dissatisfaction and body size perceptions of 58 girls (ages 6–11, 66% Black, 34% White) participating in a randomized trial for pediatric overweight. Body dissatisfaction did not differ between races; 99% of girls reported an ideal figure smaller than their current one. Black girls selected a larger silhouette to represent their ideal body size, and most girls in both racial groups underestimated their actual size. Outcomes strengthen the argument that, despite an overall preference for a larger body size, obesity might mitigate cultural factors that protect Black girls from body dissatisfaction. Additional research is needed to enhance understanding of children's body size perceptions and dissatisfaction to inform assessment and treatment of pediatric obesity and associated disordered eating symptoms.     

Estimation of careless error and lucky guess probabilities for dichotomous test items: A psychometric application of a biometric latent class model with random effects

Medical research has extensively dealt with the estimation of the accuracy (sensitivity and specificity) of a diagnostic test for screening individuals. In this paper we apply the biometric latent class model with random effects by Qu, Tan, and Kutner [(1996). Random effects models in latent class analysis for evaluating accuracy of diagnostic tests. Biometrics, 52, 797-810] to estimate the response error (careless error and lucky guess) probabilities for dichotomous test items in the psychometric theory of knowledge spaces. The approach is illustrated with simulated data. In particular, we extend this approach to give a generalization of the basic local independence model in knowledge space theory. This allows for local dependence among the indicators given the knowledge state of an examinee and/or for the incorporation of covariates.     

Stigmatizing attitudes of the community towards people living with HIV/AIDS

This research involved an exploratory study in which a questionnaire was used to investigate the personal stigma and perceived community stigma regarding HIV/AIDS in a South African community. Student fieldworkers interviewed a convenient sample of 901 respondents from different races, gender and age groups, and found that respondents tended towards stigmatizing persons with HIV/AIDS. Yet, this degree of stigmatization was significantly less severe than the degree of stigmatization that respondents attributed to the community at large. Altogether 17% of the respondents had high stigmatizing attitudes, while 42% perceived the stigmatization by others in the community to be high. Race group, personal knowledge of someone with HIV, area of residence, gender and age group impacted on the respondents' personal tendency to stigmatize those with HIV/AIDS. The article discusses the difference between the level of personal stigma attached by the respondents and that perceived by them to be attached by the community. Attention is also paid to the possible implications of stigmatizing behaviour patterns and interventions on a community level. Copyright © 2006 John Wiley & Sons, Ltd.     

单题项测量：质疑、回应及建议

研究者关于单题项测量的争论已久。支持者认为单题项测量具有时间和效率上的优势, 而反对者则认为单题项测量的信效度均无法得到保障。通过定性和定量的回顾, 归纳了单题项测量的优缺点, 剖析了以往研究对单题项测量的种种质疑并逐一进行回应。通过系统梳理, 发现单题项测量具有可以接受的信度和效度水平, 且多题项测量的效标关联效度并没有显著优于单题项测量。最后, 指出了单题项测量开发和使用过程中应该注意的事项。尽管多题项测量仍是当前研究界的主流测量方法, 但未来研究者应当更加客观地看待单题项测量。学界应当充分理解单题项测量潜在的优点和适用范围, 从而使单题项测量在管理心理学和社会科学研究中发挥其应有的作用。

The Relationship Between Right‐wing Attitudes and Cognitive Style: A Comparison of Self‐report and Behavioural Measures of Rigidity and Intolerance of Ambiguity

Two recent meta‐analytic studies addressing the relationship between cognitive style and right‐wing attitudes yielded some discrepancies. We argue that these discrepancies can be accounted for when one considers the types of cognitive style measures included in those analyses. One of these analyses primarily relied on self‐report measures, whereas the other relied on behavioural measures of cognitive style. Based on a new meta‐analysis of 103 samples (total N = 12 714) focussing on behavioural and self‐report measures of rigidity and intolerance of ambiguity, we confirmed the hypothesis that self‐report scales yield stronger relationships with right‐wing attitudes than behavioural measures. We point out potential conceptual and validity issues with both types of cognitive style measures and call for cautiousness when interpreting the magnitude of their relationships with ideology.

青少年物质主义的成因、测量与干预

物质主义是一种看重个体所拥有的财物的价值观。本文回顾了青少年物质主义的成因、测量与干预方法。青少年物质主义价值观的形成主要受家庭、同伴和媒体等因素的影响。常用的测量方法包含青少年物质主义量表、物质主义价值观量表—儿童版以及消费者卷入度等自陈量表,操作性测量工具——拼贴画,以及想象、观看社会榜样视频等启动青少年物质主义的方法。干预活动主要通过家庭、学校、媒体和社会等渠道展开。未来研究值得关注下述两点,一是从新角度考察环境对青少年物质主义价值观的影响;二是开展本土化的青少年物质主义研究。     

语义距离与创造性思维关系的元分析

自然语言处理的发展为探究语义距离与创造性思维的关系提供了可靠且有效的研究方法。近些年关于两者之间关系的研究逐渐增多,但研究结论并不一致。本研究基于创造力联想理论及扩散激活模型,通过元分析的方法探讨了语义距离与创造性思维的整体关系,并且分析了以往研究结论不一致的原因。本文经过文献检索和筛选后获得14项研究,提取r值作为效应值(共53个效应值,4729个独立样本),并使用随机效应模型进行了元分析。结果显示：语义距离与创造性思维存在中等程度的正相关(r=0.379, 95%CI [0.300, 0.452]);二者的相关强度受到被试年龄和创造性思维不同测量指标的调节。研究结果表明语义距离与创造性思维关系密切,同时解释了以往研究结论不一致的原因。上述结果不仅能为更深入地探讨创造性思维的认知神经机制提供新的研究视角和理论解释,而且有助于更全面地理解语义距离与创造性思维二者的关系及其边界条件,为更好地解释、预测和提升创造力提供科学依据和重要启示。     

亲密关系的外显测量与内隐测量及相互关系

为了验证外显与内隐的差序格局,研究者考察了最亲密的家人、恋人以及最亲密的好朋友的外显和内隐亲密程度的差异与联系,以及性别对亲密关系的影响。结果表明,三个目标对象的外显亲密程度之间存在差异,但内隐亲密程度之间不存在差异;外显和内隐亲密程度之间相关不显著;外显测量结果没有显著的性别差异,但在内隐测量中,男性比女性对恋人感觉更为亲密。研究者针对这些结果分别进行了讨论
