儿童早期自尊的行为观察研究

以自尊情感模型为理论起点,采用行为事件取样法,对58名1.5-4岁婴幼儿的掌控感和归属感事件进行系统观察。结果表明：早期掌控感源于以动作为基础的掌控行为,包括掌控自我、掌控外物和掌控他人。而归属感一方面源于儿童以不同的行为方式寻求归属,即主动归属感;另一方面源于不同情境下成人的行为使儿童获得了归属,即被动归属感。掌控感和归属感事件均随年龄增长而逐渐减少,反映了个体自尊的早期形态。     

概率性输入,噪音“与”门(PINA)模型

当前认知诊断测验的主要目的是对被试进行合理分类,进而采用类别变量去描述被试对某技能或知识(即认知属性)的掌握情况,但该粗糙的分类方法不能精细地区分不同被试之间的差异。对此,采用掌握概率这一连续变量去描述被试对某认知属性的掌握情况是一种值得尝试的做法。本文首先基于高阶潜在特质(简称"潜质")模型给出了认知属性掌握概率的量化定义,之后与多成分潜质模型相结合提出了概率性输入,噪音"与"门(PINA)模型;其次,采用MCMC算法实现了对PINA的参数估计,结果表明参数估计程序对各参数的估计返真性均较好;最后,以ECPE数据为例来说明PINA在实际测验分析中具有可行性。     

加班一定会带来疲倦吗？加班时长对工作恢复水平的影响机制研究

基于资源保存理论,采用日记研究法探讨了加班对工作恢复的影响以及闲暇时间控制和掌握体验在其中的作用。结果表明：（1）加班时长显著负向影响工作恢复水平;（2）加班时长通过闲暇时间控制影响工作恢复水平;（3）掌握体验不仅调节了加班时长和闲暇时间控制之间的关系,还进一步调节了加班时长通过闲暇时间控制影响工作恢复水平的间接关系,在高水平的掌握体验下,加班时长通过闲暇时间控制影响工作恢复水平的间接效应不再显著。这意味着加班未必一定抑制工作恢复,获得积极体验从而促进资源的生成可能才是恢复的关键,这为企业和个人提供了有效进行工作恢复的指导。     

Coping,mastery, stress appraisals,mental preparation,and unit cohesion predicting distress and performance: a longitudinal study of soldiers undertaking evacuation tasks

Abstract

The study aimed to assess the associations of psychological and military variables with distress and performance evaluation among 168 Israeli soldiers who took part in evacuating fellow Israeli civilians in the summer of 2005 during the disengagement from Gaza. Coping, mastery, stress appraisals, mental preparation, unit cohesion, and psychological distress were assessed at T1, one to two weeks before the disengagement. A sub-sample of 68 of the 168 soldiers completed the distress measure again at T2, eight to nine weeks after T1, together with performance evaluation of the disengagement task. The main findings indicated positive associations of T1 distress with high T1 emotion-focused coping, and negative associations with education and T1 mastery. Emotion-focused coping at T1 predicted low performance evaluation at T2, while mental preparation at T1 predicted high performance evaluation at T2. Stress appraisals at T1 were found to be an important mediator of the associations of T1 coping, mastery, unit cohesion, and mental preparation with T1 distress. Similar mediator results were found for T2 performance evaluation.     

Distinguishing between self-control and perceived control over the environment to understand disadvantaged neighbourhood health and lifestyle outcomes

Abstract

Objective: The current study aimed to test whether and how self-control and perceived control play a role in health outcomes and lifestyle differences between disadvantaged and non-disadvantaged neighbourhoods.

Design: Cross-sectional survey data including demographics was collected from 3758 participants. Main outcome measures: With the survey, self-control, perceived control, health status and lifestyle variables were assessed.

Results: Participants in disadvantaged neighbourhoods reported poorer general health, as well as unhealthier lifestyles compared to participants in non-disadvantaged neighbourhoods. Self-control was likewise positively associated with health and lifestyle variables. However, self-control did not differ between participants from different neighbourhoods. Perceived control over the environment mediated between type of neighbourhood and health, with participants from a disadvantaged neighbourhood reporting a lower sense of perceived control, which in turn was associated with poorer self-reported general health and less healthy lifestyle choices.

Conclusion: This reveals that perceived control over one’s life and the environment is more important than self-control when explaining health differences between neighbourhoods.     

Changes over time from baseline poor self-rated health: For whom does poor self-rated health not predict mortality?

The aim of this study was to understand for whom and why poor self-rated health (SRH) is a less valid predictor of longevity or future health by examining the predictors of decline in health among people with poor baseline SRH. The sample included 409 participants in the Cross-Sectional and Longitudinal Study of the old–old (75+) in Israel, who were self-respondents and rated their health as poor at baseline and their status was known at follow-up 3.5 years later: deceased/moved to proxy interview/remained in poor SRH/or improved SRH. Baseline measures included self-reported medical status, physical, cognitive, psychological and social functioning. Findings showed that less decline in health was predicted by less difficulty in physical and cognitive functioning at baseline and by a more active physical and social life, after controlling for socio-demographics. Most of the predictors retained a unique contribution in a multivariate model, suggesting that engagement in meaningful activities serves as an indicator of better health and longer survival even within a group of old–old people in poor health. It may reflect greater social support, contribute to fitness and/or provide a sense of mastery, which could explain similar findings regarding gender and race/ethnicity groups for whom SRH is a less potent predictor of mortality.     

Perceived control and long-term changes in disability in late middle-aged and older persons: An eight-year follow-up study

This article examined the predictive role of perceived control in long-term changes in disability among 1541 independently living older persons. Disability referred to self-reported difficulties with (instrumental) activities of daily living. Perceived control referred to the extent to which one assumes oneself as having control over one's life chances, unlike the fatalistic assumption that one's life is ruled by external factors. Data on disability and perceived control were collected in 1993 and recollected in 2001. Covariates included age, gender, living arrangement, level of education, and the number of chronic medical conditions. Regression equations were estimated with disability in 2001 as outcome and the selected variables as predictors. The level of perceived control decreased and the level of disability increased significantly over an 8-year period. The predictive role of perceived control for subsequent change in disability was statistically significant but not very strong. The association between perceived control in 1993 and disability in 2001 was stronger for older persons (>65 years) compared to younger persons (≤65 years).     

Personal Resources and the Social Distribution of Depression

This paper addresses the hypothesis that gender, age, marital status, and SES matter for depression partly because of associated differences in the availability and/or impact of the personal resources of mastery and self-esteem. It is argued that findings indicating that the social distributions of these resources complement those for depression would provide preliminary support for this hypothesis. Based on a large urban community sample (n = 1,390), our findings fail to support the availability hypothesis in relation to marital status, provide only modest support in reference to age and gender, but yield compelling support in relation to socioeconomic status (SES). Indeed, variations in the availability of these resources, especially mastery, provide a largely, if not entirely, adequate explanation for the SES–depressive symptoms relationship and accounts for nearly half of the SES–Major Depressive Disorder relationship. Although the significance of mastery was more pronounced among women and unmarried persons, such differences did not contribute to understanding observed gender or marital status variations in depression.     

Infant and parental pathways to pre-school cognitive competence

In a longitudinal study, 62 parent-child dyads were seen during the second year of life and at 4 years of age. At 12 months, measures included parental sensitive responsiveness during free play, knowledge of cognitive-communicative development in infancy, and level of exploration and disinhibitedness of the infant. At 16 and at 20 months, parental responsiveness and directiveness and infant task mastery behaviour were assessed in constructive play. Quality of verbal guidance of the parent was assessed in a joint attention situation. At 48 months of age, the McCarthy Scales of Children's Abilities were administered at home, together with dyadic tasks. A path analysis revealed a model in which both verbal abilities and perceptual performance outcome measures were well predicted by the quality of parental verbal guidance in the second year. The latter measure was shown to be independent of the socioeconomic status of parents in the group, but was significantly related with knowledge of infant cognitive-communicative development. Of the measures at the outset of the second year, only socioeconomic status remained as having a direct path at pre-school age. The consistency of the model with other empirical findings underscores parental verbal scaffolding as an important shaper of cognitive development.
