本文基于DINO模型开发出一种分离型的多级评分认知诊断模型(P-DINO模型),并采用Monte Carlo模拟与实证研究相结合的范式,探讨了新模型的性能与有效性。结果表明:(1)P-DINO模型参数估计精度较好,参数估计的稳健性较强。(2)采用MCMC算法可以实现该模型的参数估计,估计结果较理想。(3)测验长度的增加能有效提高模型的判准率,被试人数的增加对判准率的提高相对较小,属性个数的增加会降低判准率。(4)在抑郁症状评估中,P-DINO模型的表现要优于DINO模型与传统的抑郁症状评估。 相似文献

During young adulthood the suicide rate among Blacks rises dramatically and approaches that of the U.S. general population, requiring that prevention efforts include a focus on Black young adults. Although most research on suicidality among Blacks has focused on risk factors observed in the dominant culture, in this study the authors examined associations between perceived discrimination, racism, and acculturation with lifetime suicidal ideation (SI) and suicide attempt (SA) among Black young adults. Two hundred fifty Black or African American individuals aged 18-24 residing in a midsize northeastern city were recruited to participate through advertisements. Participants filled out self-report questionnaires. Logistic regressions were used to examine the association of each predictor with SI and SA. Greater perceived acculturation was associated with SI in univariate and multivariate models. There were no other statistically significant results concerning the predictors of interest. The link between perceived acculturation and SI is consistent with limited available data, indicating the need for further study including the potential mechanism(s) for the association. Limitations include the cross-sectional design and reliance on subjective measures. 相似文献

"道"性-"水"性-人性-中国人人格具有内在一致性,形成了一个一以贯之的有机体系。在这一有机体系中,作为"道"性的"代言人","水"性成为"道"性与人性及中国人人格间的"中介者"。以"几于道"的"水"为中介,通过对道家思想的分析,反观得到了道家思想影响下中国人的人性建构及人格特征,具体表现为:在思维上明"道"并懂得"道"的运行规律,以联系、变化和矛盾的眼光看待万事万物,情绪情感上静而不躁,意志品质上柔韧而不强作妄为,行事处世上既超脱一已之私、于物寡欲,又能待人谦退不争,并能从整体上显现出"道"之"自然本真"的根本特性。文末探讨了道家思想文化影响下,所形成的中国人独特的人格特征与现代化建设事业可能的适应情形。 相似文献

We conducted this cross-sectional study among 392 Japanese and 294 Vietnamese mothers who attended routine child health visits
in a Japanese city and at a tertiary hospital in Vietnam, in order to investigate the prevalence and associated sociodemographic,
parenting, and psychological characteristics of low maternal confidence in child rearing among them. All data were collected
from medical files in Japan, and from medical files and self-administered questionnaires in Vietnam. The proportion of mothers
without secure feeling of confidence in the present study was 22% in Japan and 66% in Vietnam. Significant factors associated
with a lack of confidence were first-time motherhood and unintended pregnancy in the Japanese dataset and younger age in the
Vietnamese dataset. In both groups, a higher proportion of mothers who lacked confidence reported negative parenting outcomes
than did confident mothers. Among the three psychological measurements (mood, self-efficacy and depression), higher self-efficacy
was associated independently with a significantly reduced risk of not having confidence in child rearing. These results suggest
the importance of developing parenting support programs to help Japanese and Vietnamese mothers, particularly those who are
young, first-time mothers or who became pregnant unexpectedly, improve their self-efficacy. 相似文献

单纯呈现效应与积极情感的产生 总被引:1,自引:1,他引:0
该研究以汉语双字词为刺激材料 ,以大学生为被试,首先分别检验了标准的情感启动范式和单纯呈现范式的有效性.然后,用在标准的单纯重复呈现范式中产生了典型单纯呈现效应的中性刺激,替换标准情感启动范式中情感属性为积极的启动刺激,再次进行标准的情感启动测验,仍然观察到了情感启动效应,而同样是这些中性刺激,当没有被重复呈现时,在标准的情感启动测验中没有观察到情感启动效应.结果表明,刺激的重复呈现会导致偏好的产生,使其能够起到积极情感刺激的作用.研究认为,刺激的重复呈现,可能是积极情感产生的一个来源. 相似文献

The DFC Intelligence predicts worldwide online game revenues will reach $9.8 billion by 2009, making online gaming a mainstream recreational activity. Understanding online game player personality traits is therefore important. This study researches the relationship between personality traits and life satisfaction in online game players. Taipei, Taiwan, is the study location, with questionnaire surveys conducted in cyber cafe shops. Multiple regression analysis studies the causal relationship between personality traits and life satisfaction in online game players. The result shows that neuroticism has significant negative influence on life satisfaction. Both openness and conscientiousness have significant positive influence on life satisfaction. Finally, implications for leisure practice and further research are discussed. 相似文献
