流动儿童同伴侵害的特点及与内化问题的循环作用关系:一项追踪研究

本研究采用纵向设计,以北京市426名四、五年级流动儿童为被试,进行连续4次的追踪测查,考察流动儿童同伴侵害的特点及其与内化问题的动态相互作用关系。结果发现:(1)打工子弟学校流动儿童的同伴侵害与内化问题水平比公立学校流动儿童高;流动儿童的流动性越大,同伴侵害和内化问题越多。(2)控制了性别、年级、家庭社会经济地位(SES)和流动性后,从T1到T2,同伴侵害与孤独感为相互作用关系,且同伴侵害可以显著预测抑郁,但对社交焦虑的预测作用不显著,而从T2到T4,同伴侵害和3种内化问题的相互作用模式完全一致,即T2时的社交焦虑、抑郁和孤独感显著预测T3的同伴侵害,进而显著预测T4的社交焦虑、抑郁和孤独感。(3)抑郁、孤独感与同伴侵害的循环作用在两类流动儿童中具有较强的稳定性,而在社交焦虑和同伴侵害的模型中,打工子弟学校流动儿童的同伴侵害对社交焦虑的作用比公立学校流动儿童更大。可见,同伴侵害和内化问题呈循环作用关系,未来预防/干预研究可以聚焦于减少流动儿童的同伴侵害或内化问题的角度打破二者的恶性循环,帮助他们建立良好的人际关系,构建良性循环,促进他们的积极发展。     

教师心理健康评价量表的编制及现状研究

在理论分析和借鉴前人研究成果的基础上,自行编制了针对我国教师心理健康的评价量表,并对来自北京、河北、江苏、山东、山西、青海、浙江等7个省市的1819名教师进行了测试。结果发现:《教师心理健康评价量表》由自我、社会、工作和生活四个分量表构成。经检验,《教师心理健康评价量表》具有良好的信度和效度,可以在今后相关研究中作为了解教师心理健康状况的测量工具使用;同时研究还发现,幼儿园、小学、初中和大学的教师同时存在发展性问题和适应性问题,而高中教师只有适应性问题,没有发展性问题。     

Selecting polychoric instrumental variables in confirmatory factor analysis: An alternative specification test and effects of instrumental variables

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different numbers of IVs. Our results show that specification tests derived for continuous data are extremely oversized at all sample sizes when applied to ordinal variables. Possible modifications for ordinal data are proposed in the present study. Simulation results show that the modified specification tests with all available IVs are able to detect model misspecification. In terms of estimation accuracy, the PIV approach where the IVs outnumber the endogenous variables by one produces a lower bias but a higher variation than the PIV approach with more IVs for correctly specified factor loadings at small samples.     

Approximated Penalized Maximum Likelihood for Exploratory Factor Analysis: An Orthogonal Case

The problem of penalized maximum likelihood (PML) for an exploratory factor analysis (EFA) model is studied in this paper. An EFA model is typically estimated using maximum likelihood and then the estimated loading matrix is rotated to obtain a sparse representation. Penalized maximum likelihood simultaneously fits the EFA model and produces a sparse loading matrix. To overcome some of the computational drawbacks of PML, an approximation to PML is proposed in this paper. It is further applied to an empirical dataset for illustration. A simulation study shows that the approximation naturally produces a sparse loading matrix and more accurately estimates the factor loadings and the covariance matrix, in the sense of having a lower mean squared error than factor rotations, under various conditions.     

Let It Go: Positive Affect Attenuates Sunk Cost Bias by Enhancing Cognitive Flexibility

Sunk cost bias is a pervasive problem in consumer decision making. It occurs when people continue to invest resources toward unsuccessful outcomes merely because they previously invested in them. This tendency exists because people devote too much attention to prior investments without considering how other factors may impact their decision outcome. While many suggested interventions to attenuate sunk cost bias involve altering cognitive processes, we examine an alternate affective route. Specifically, we propose that inducing positive affect attenuates sunk cost bias by naturally facilitating flexible thought processes. Across four studies, using hypothetical and real decision tasks, we find that positive affect induced in three different ways consistently attenuates sunk cost bias involving money, time, and effort investments. Further, we demonstrate that this occurs because people experiencing positive affect have enhanced cognitive flexibility. They consider more relevant decision factors and perceive sunk cost as having less of an influence on their decision outcomes. Then, in a fifth study, we show that a thought intervention promoting flexibility can attenuate consumers’ suboptimal commitment tendency in a field setting.     

Perceived Social Support Mediates the Relations Between Parental Attachment and Posttraumatic Growth and Resilience in Adolescents Following the Yancheng Tornado

Previous studies have shown that parental attachment is associated with higher levels of posttraumatic growth (PTG) and resilience in individuals who have experienced traumatic events. The present study investigated perceived social support as one pathway in which parental attachment is related to PTG and resilience among Chinese adolescents who have experienced trauma by considering the role of perceived social support. Participants were 443 Chinese adolescents who had experienced a severe tornado a year prior to this study. The results showed that our model fitted the data well [χ²/df = 2.847, comparative fit index (CFI) = 0.970, TLI = 0.963, root mean square error of approximation (RMSEA) (90% CI) = 0.065 (0.056–0.073)] and revealed that perceived social support partially mediated the relationship between parental attachment, and PTG and resilience. The clinical implications and limitations of our research, and recommendations for future research are discussed in this paper.     

Digging beneath the surface: Results from stage one of a qualitative analysis of factors influencing the well-being of trans youth in Quebec

ABSTRACT

Background: The literature on trans youth has been dominated by etiological studies interested in trans experience as a medical phenomenon. An emerging body of literature has begun to document that trans youth are a diverse, vulnerable, yet resilient population, and to investigate the role of various sites of support such as the family, peer groups, institutions, and community spaces in contributing to or impeding trans youth's well-being.

Method: This article presents the results of Stage One of interviews (n = 24) conducted for a Community-Based Participatory Action Research (CBPAR) qualitative research project based in Quebec. It studies the factors that enhance trans youth's well-being as well as the factors of oppression that negatively affect it. This paper offers a brief overview of the anti-oppressive methodology used for this project, emphasizing how CBPAR was combined with Grounded Theory (GT) methods to encourage the direct involvement of communities and the translation of knowledge into action.

Results: We present preliminary categories emerging through the ongoing axial coding process. These categories address trans youth's experiences in and perceptions of various “sites”: 1) healthcare services both for gender-related and general care, 2) other institutional spaces, 3) the family and other social circles, and 4) community spaces.

Conclusion: While much of this study's results support existing evidence on trans youth's experiences, they also provide a more nuanced portrayal of the complex ways in which recognition, as well as non-, mis-, or mal-recognition, influence trans youth's well-being at different sites. We also argue that recognition itself must be considered through the lens of intersectionality.     

Self‐tracking in effortful activities: Gender differences in consumers' task experience

Despite the increasing use of self‐tracking technologies, surprisingly little empirical research has examined the effect of self‐tracking in effortful activities on consumers' task experience. Accordingly, the present research examined the moderating role of gender in the effect of self‐tracking in effortful activities on perceived competence and task experience (namely, enjoyment and subjective vitality). Across three experiments, results suggested that self‐tracking in effortful activities increases the perceived competence, enjoyment, and subjective vitality of females more than males, and that perceived competence explains these interaction effects. Interestingly, an experimental manipulation designed to prompt overestimation of abilities attenuated these positive effects among females. As such, the present research contributes to the literatures on self‐tracking and feedback instrumentality, and offers important practical implications for marketers.     

The Effect of the Running‐Man Emergency Exit Sign and Its Installed Location on Human Directional Choice

Understanding the meaning of an emergency exit sign is essential for escaping from a building during a disaster. According to International Organization for Standardization 7010:2011, there are leftward and rightward running‐man exit signs indicating the location of an exit door. However, there is neither an application rule regarding which direction the sign should point nor a rule for where it should be attached in the horizontal dimension. We examined the effect of the heading direction of the running man and its horizontal locations on the selection of exit directions. A modified spatial Stroop task as an unforced‐choice task was designed by combining the running man's heading direction and its horizontal location. The results showed both facilitation and inhibition effects, conflict adaptation, and post‐error slowing reflecting top‐down control. These findings suggest that the heading direction of the running‐man exit sign includes evident directionality. This should be considered in designing and establishing standardized emergency exit signs. Copyright © 2016 John Wiley & Sons, Ltd.
