实际应用中测验往往具有多维结构, 如果仍采用单维IRT方法进行等值, 会得到不准确的结果。因此对于多维结构的测验, 需要使用多维IRT等值方法来实现参数的转换。基于共同题设计, 文章通过模拟研究的方法, 考察了不同铆测验设计下几种多维IRT等值方法的表现, 同时考虑了测验长度、两个维度题目数量的比例、铆测验长度、铆测验的选择策略、两个维度之间的相关和等值群体的能力水平差异六个因素的影响。所比较的多维IRT等值方法有:均值/均值(MM)方法, 均值/标准差(MS)方法, Stoking-Lord (SL)方法, Haebara (HB)方法, 最小平方(LS)方法。结果显示:(1) SL, HB和LS方法得到的等值误差均方根最小, 且在各条件下表现较为稳定。(2) MM和MS方法在非等组条件下呈现出很大的误差均方根。(3)铆测验设计对SL, HB和LS方法的等值结果没有显著影响。(4)在两个维度之间的相关较高, 测验长度和铆测验长度较长, 等值群体的能力水平没有差异的条件下, SL, HB和LS方法得到的等值误差均方根最小。 相似文献

Previous research on the relationship between collectivism and corruption has not investigated their co‐variation over time. In this study, we use Google Ngram Viewer to track the frequency of words related to collectivism and corruption in American books (1800–2000) and in Chinese Books (1970–2008). The results demonstrate that a positive association between the usage of these terms during the periods in both Chinese and American books, with changes in words related to collectivism preceding changes in words related to corruption in American books. The theoretical and practical implications are also discussed. 相似文献

Studies indicate that there is a positive relationship between openness to experience and creativity. However, relatively little attention has been given to the mechanism of this relationship. On the basis of previous findings, we hypothesized a conceptual model and tested the mediating role of intrinsic motivation and the creative process engagement in the relationship between openness to experience and creativity. One hundred and ninety‐eight undergraduates in Malaysia participated in the study and completed an online measure of openness to new experience, creativity, intrinsic motivation, and the creative process engagement. Consistent with the hypothesis, people who scored high on openness reported high intrinsic motivation. The high motivation enhanced engagement in creativity‐related activities, which in turn, improved self‐rated creativity. The findings not only shed light on mechanisms that underlie in the openness‐creativity linkage but they also highlight the importance of intrinsic motivation and creative process engagement in the linkage. Together, the study extends the effect of personality trait on creativity and offers a new direction for future studies. 相似文献

Shyness has been found to have a negative impact on creativity. However, little attention has been given to the underlying process of the relationship between shyness and creativity. On the basis of literature, we hypothesize that shyness has an indirect impact on creativity through creative process engagement. Two studies were conducted on undergraduate students (Study 1) and working adults (Study 2) to test the hypothetical relationship. Analysis on participants self‐report showed that shyness was negatively associated with self‐reported creativity as well as creative process engagement. There was a positive relationship between creative process engagement and creativity. More importantly, mediation analysis supported that shyness was indirectly linked to creativity via creative process engagement. Specifically, shy people are found to be less involved in creativity‐relevant processes such as information searching and idea generation. The low level of creative process engagement, in turn, hinders their creativity. The findings not only lend support to the detrimental effect of shyness on creativity but also shed light on the underlying mechanism of the relationship. 相似文献

本文通过两个研究探讨了群体因素中的班级欺凌规范如何通过同辈压力、群体害怕影响欺凌行为的发生。研究1为实验研究, 被试为186名小学高年级学生(Mage = 11.36 ± 0.99岁)。结果表明在不同情境(欺凌/非欺凌)的启动下, 各变量得分均具有显著差异; 进一步分析仅发现同辈压力的中介作用边缘显著。研究2为相关研究, 943名小学高年级及初二学生(Mage = 12.00 ± 1.32岁)填写班级欺凌规范、同辈压力和欺凌行为问卷。HLM分析显示同辈压力在班级欺凌规范与欺凌行为起显著中介作用。 相似文献

研究旨在考察个体在选择职业时是否会为了更好的环境条件(组织、城市)而降低对兴趣的要求。对63名大学生被试开展了两个实验,采用在环境条件和兴趣水平上有不同程度差异的职位配对来模拟两难决策。结果发现:(1)对不同组织声望和兴趣水平的职位的选择无性别差异;(2)组织声望差距、组织声望差距与兴趣差距的交互作用能显著预测职位的选择;(3)对不同城市级别和兴趣水平的职位的选择有性别差异,男生比女生更少放弃兴趣;(4)兴趣差距、城市级别差距与兴趣差距的交互作用能预测男生的选择,只有兴趣差距能预测女生的选择。结论:个体会为了更好的环境而或多或少在兴趣方面妥协。 相似文献

教学设计是为优化教学效果而形成的教学实施方案。为提高学习表现,认知负荷理论认为在组织教学设计时需考虑内、外认知负荷两大因素,但少有研究关注学生在学习过程中的体验。本研究通过单词复合性操纵内在负荷,通过呈现方式操纵外在负荷,探究两类负荷对心流体验及表现的影响。结果发现,内在负荷对心流及表现均有影响,外在负荷仅在低水平组表现出对心流及表现的影响,另外内外负荷在低水平组的表现上存在交互作用。结果表明,教学设计中的内在负荷是影响心流及表现的稳定因素,外在负荷不仅受知识水平影响,其对表现的有效性还受内在负荷的调节。 相似文献

Patients with psoriasis may have increased risk of psychological comorbidities. This cross-sectional study aimed at determining associations between sociocultural and socioeconomic factors with the Depression Anxiety Stress Scale (DASS) scores and the Dermatology Life Quality Index (DLQI) scores. Adult patients with psoriasis were recruited from a Dermatology outpatient clinic via convenience sampling. Interviews were conducted regarding socio-demographic factors and willing subjects were requested to complete the DASS and DLQI questionnaires. The Pearson χ2 test, Fisher’s exact test and multivariate logistic regression were used for statistical analysis to determine independent predictors of depression, anxiety, stress and severe impairment of quality of life. Unadjusted analysis revealed that depression was associated with Indian ethnicity (p = .041) and severe impairment of quality of life was associated with Indian ethnicity (p = .032), higher education (p = .013), higher income (p = .042), and employment status (p = .014). Multivariate analysis revealed that Indian ethnicity was a predictor of depression (p = .024). For stress, tertiary level of education (p = .020) was an independent risk factor while a higher monthly income was a protective factor (p = .042). The ethnic Indians and Malays were significantly more likely than the ethnic Chinese to suffer reduced quality of life (p = .001 and p = .006 respectively) and subjects with tertiary education were more likely to have severe impairment of quality of life (p = .002). Our study was unique in determining sociocultural influences on psychological complications of psoriasis in a South East Asian population. This has provided invaluable insight into factors predictive of adverse effects of psoriasis on psychological distress and quality of life in our patient population. Future studies should devise interventions to specifically target at risk groups in the development of strategies to reduce morbidity associated with psoriasis. 相似文献
