父母严苛型教养方式与青少年自杀倾向:一个有调节的中介模型

在对西安市四所中学4071名中学生进行问卷调查的基础上,实证研究了父母严苛型教养方式与青少年自杀倾向之间的关系。结果表明:(1)从直接效应上讲,父母严苛型教养方式和个体自身对自杀行为的合理化认知对青少年自杀倾向具有显著的正向预测作用;(2)青少年对自杀行为的合理化认知在父母严苛型教养方式和自杀倾向的相关关系中起部分中介作用;(3)在严苛型教养方式通过自杀行为合理化认知影响自杀倾向的模型中,同伴支持变量不存在显著的调节作用,而教师支持变量在这一模型的直接路径与中介模型后半段均起调节作用。     

基于作答时间数据的改变点分析在检测加速作答中的探索——已知和未知项目参数

相对于传统的离散作答数据, 作答时间作为连续数据, 可以提供更多信息。改变点分析(change point analysis)技术在心理和教育领域是一个比较新的技术。本文一方面对改变点分析在心理测量领域的应用进行了一个综合的总结和分析; 另一方面, 将基于作答数据的两种改变点分析统计量推广到作答时间数据, 将改变点分析技术应用到测验异常作答模式：加速作答speededness的检测上。采用两种检验方法：似然比检验和Wald检验, 分别在已知和未知项目参数的条件下, 实现异常作答模式的检测。结果表明, 所采用的方法对于加速作答行为的检测具有很高的检验力, 同时能够很好的控制I类错误率。实证数据分析进一步表明本文中所使用的方法具有应用价值。     

首词素位置概率信息未参与汉语阅读的词切分：基于副中央凹加工的证据

本研究采用边界范式,考察汉语阅读中读者是否在副中央凹处利用首词素的位置概率信息进行词切分和词识别。采用2（首词素位置概率：高、低）×２（预视类型：相同预视、假字预视）的被试内实验设计,以双字词为目标词,记录大学生阅读句子时的眼动轨迹。结果发现,在跳读率和第一遍阅读的眼动指标中,被试在高、低首词素位置概率条件中获得的预视效益量无显著差异。该结果表明,读者并未在副中央凹处加工首词素的位置概率信息。结合前期研究推断,首词素位置概率信息没有作用于汉语阅读的词切分和词识别。     

父母差别对待与青少年问题行为的关系：一个有调节的中介模型

通过问卷调查的方式,采用同胞不同经历问卷、关系网络问卷和问题行为量表对开封市1179名初高中学生进行研究。研究结果显示：（1）父母差别对待与外/内化问题行为呈显著正相关;同胞关系与外/内化问题行为呈显著负相关;父母差别对待和同胞关系呈显著负相关。（2）同胞关系在父母差别对待与外/内化问题行为之间起部分中介作用。（3）“父母差别对待→同胞关系→外/内化问题行为”这一中介路径的前半段受出生顺序调节;与年幼个体相比,父母差别对待对年长个体的同胞关系影响更大。出生顺序会调节父母差别对待对同胞关系的影响,提示二胎家庭要更关注年长个体的变化。     

人工肝支持系统治疗肝衰竭的研究进展

目前肝衰竭发病率和病死率仍然较高,肝衰竭成为威胁患者生命的严重疾病。基于肝脏具有强大再生能力,人工肝支持系统作为一种“过渡”措施,为肝衰竭患者的肝功能恢复赢得时间。人工肝支持系统根据性质不同分为非生物型人工肝、生物型人工肝和混合型人工肝。目前非生物型人工肝已在肝病治疗领域被广泛应用,但生物型及混合型人工肝的临床应用还存在很多问题需要进一步研究和解决。因此本文对人工肝的作用、临床应用现状、存在问题及研究进展进行综述。     

多级评分模型下的题库结构对CAT的影响分析

在多级评分模型下,项目的难度参数或步骤参数有多个,在对多级评分模型进行选题时,通常对项目的多个难度参数用一个综合的指标来概括.当对每个项目的难度参数进行有效的综合后,综合后的难度参数分布发生了改变,这时如果增加适量的平均难度较难或较易的项目进入题库,测验的精度和项目的曝光率都有一定的改善.     

The Mystery of Chinese People’s Happiness

The great improvement in economic wealth and social welfare over the decade doesn’t promote the Chinese people’s happiness. We construct a theoretical framework which covers economic wealth, social welfare, individual functional capability to explore the impact factors and determinants of the Chinese people’s happiness. Based on a national wide questionnaire survey in China, we test and modify the framework by the method of structural equation model. The empirical findings indicate that there are direct and indirect effects on the formation of happiness. For the direct effect, both the increasing of economic wealth and social welfare improves the national happiness, while the individual functional capability reduces it. For the indirect effect, the individual functional capability also reduces happiness by negatively affecting economic wealth and social welfare. The negative effect that played by individual functional capability overwhelms the positive effect played by economic wealth and social welfare. This causes the Chinese people’s happiness goes down while the economic wealth and social welfare are improving. Finally, we conclude that the Chinese people’s happiness is more about individual functional capability rather than social welfare or economic wealth.     

Parental Health and Children’s Functioning in Immigrant Families: Family Roles and Perceived Treatment at School

Although parents’ health condition is generally thought to be related to their involvement in their children’s functioning, the possible dynamics behind the scenes in school contexts with immigrant children has received little attention. This study examined the association between parents’ health condition and their children’s academic and behavioral functioning, as well as the mediation effects of parents’ school engagement and children’s perceived treatment at school among 607 immigrant families with 10- to 12-year-old children. Using structural equation modeling, the results indicated that parents’ poor health condition was associated with children’s increased behavioral problems. Parents’ school engagement fully mediated the association between parental health condition and children’s academic achievement and partially mediated the association between parental health condition and children’s behavior problems. Notably, higher levels of parents’ school engagement were associated with increased behavior problems, demonstrating a unique feature in these immigrant children’s developmental functioning. Higher levels of perceived harsh treatment by peers at school due to children’s immigrant identity were associated with these children’s greater risks of behavior problems. The results suggested what may lie behind the scenes in these children’s behavioral problems is that many of these children who act out and are brought to the school office for disciplinary issues may suffer from perceived discrimination and bad treatment by their peers. The findings provide important implications for researchers, healthcare practitioners, and educators seeking to understand this subpopulation and to design and implement family support and prevention programs for young adolescents from immigrant backgrounds.     

Associations between childhood biomedical factors,maternal smoking,personality traits,Body and Mass Index and the prevalence of asthma in adulthood

Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.
