1992年以来中学生心理健康的变迁:一项横断历史研究   总被引:7,自引:0,他引:7  
辛自强  张梅 《心理学报》2009,41(1):69-78
我国中学生的心理健康状况是否真的在逐渐下降呢?为回答这个问题,研究采用“横断历史研究”这种特殊的元分析方法,选取1992年至2005年间107篇采用90项症状自评量表(SCL–90)的研究报告,分析了111925名中学生在该量表9个因子上得分随年代的变化情况。研究结果表明:(1)SCL–90的7个因子均值与年代正相关显著(0.22~0.35),7个因子均值的增加量为0.09~0.22(效果量d为0.06~0.35),这说明1992至2005年间中学生的心理问题在缓慢增加,即中学生健康水平缓慢下降。(2)SCL–90的7个因子的标准差与年代间正相关显著(0.19~0.38),这说明中学生的心理健康水平不再像以前那样趋同,而是逐年变得更为分化。(3)中学生SCL–90得分与社会威胁、教育状况、经济状况三方面的10项社会指标相关显著,这说明社会变迁是预测中学生心理健康水平的重要因素  相似文献

In this special issue of the Journal of Investigative Psychology and Offender Profiling, we explore a Bayesian approach to journey-to-crime (JTC) estimation with an emphasis on the statistical models used. The approach conceptualises the probability that an offender lives at one location as the product of the probability distribution from a JTC estimate along with the probability distribution of other offenders who committed crimes in the same locations. The Bayesian approach is appropriate as the second part is conditional on the first part. The introduction gives the background behind the methodology and suggests how future improvements can be made by integrating new information. Finally, the papers in the special issue are introduced.

Abstract

Behind an intrusive mother’s view of her actual child lies a disproportionate, hidden desire to revive an ideal relationship with a perfect mother. The resulting image of an idealized child then becomes a strategic aspect of the mother’s own identity, representing an idealized figure from her own past. As the mother’s idealization is disturbed by the reality of the child, the mother experiences the situation between herself and the baby as “pathological,” that is, disruptive to her. She then attempts to repair the idealization by resisting any change in the status of her relationship to her child, even as the child grows older. Her rigidity in this regard necessarily excludes a paternal presence that could challenge or change the mother–infant idealized dyad. The mother’s orientation is also contradictory to, and acts as a resistance to, psychoanalytic therapeutic interventions, which aim at any “change.”  相似文献

The microstructural evolution of nanocrystalline Ni–W alloys with annealing temperature and more specifically grain boundary (GB) character is investigated through several techniques and correlated with the hardening behaviour. It is shown that two distinct regions can be identified in relation to the annealing temperature and the microstructural evolution. At temperatures below 550 °C (Regime I), a small increase in grain size is observed and is accompanied by a significant hardening and an increase in the fraction of Σ3 incoherent twin boundaries. At temperatures above 550 °C (Regime II), the thermal stability is overcome and important grain growth occurs with a decrease in both the volumic fraction of GBs and the microhardness. It is suggested that the microhardness evolution during heat treatment is influenced by two opposing processes: an increase in the fraction of incoherent twin boundaries (hardening effect) and grain growth (softening effect). Both aspects are directly associated with the mean free path of mobile dislocations.  相似文献

This article examines the history and current state of the Russian Orthodox Church (ROC) in China. It analyses both the declared and actual approach of the Chinese authorities towards Orthodox believers in China, as well as the attitude taken towards that approach by the authorities in Russia, where the ‘Orthodox factor’ plays an increasingly prominent role in domestic and foreign policy. The author shows that Russia’s most senior political leaders assist the ROC to strengthen the status of the Chinese Autonomous Orthodox Church (CAOC) and create better conditions for Chinese Orthodox believers. That effort has elevated the ‘Orthodox question’ to become an important issue of bilateral relations. As a result, and despite a lack of enthusiasm from the Chinese side, conditions could be created in the coming years for the normal functioning of the CAOC. At the same time, the Chinese Government is likely to consider it not as an autonomous part of the ROC (as the Orthodox canon considers it) but as one of the ‘patriotic religious organisations’ registered first at the provincial, and possibly later at the national level.  相似文献

The CaR–FA–X model [Williams, J. M. G., Barnhofer, T., Crane, C., Hermans, D., Raes, F., Watkins, E.,?…?Dalgleish, T. (2007). Autobiographical memory specificity and emotional disorder. Psychological Bulletin, 133(1), 122–148. doi:10.1037/0033-2909.133.1.122] is the most prominent and comprehensive model of overgeneral autobiographical memory (OGM) and provides a framework for OGM. The model comprises of three mechanisms, capture and rumination, functional avoidance and impaired executive control. These can independently, or in interaction, account for OGM. This systematic review aims to evaluate the existing research on the CaR–FA–X model, and trauma exposure studies specific to child and adolescent populations. The following databases were searched: “PsychInfo”, “PsychArticles”, “PubMed”, “Web of Science”, “Medline”, “SCOPUS” and “Embase” for English-language, peer-reviewed papers with samples <M?=?18 years, published since 1986. Support was reported for a relationship between trauma exposure and OGM as well as for capture errors and OGM. Limited support was found for rumination, avoidance and impaired executive control in isolation. No support was found for interacting mechanisms and OGM. Partial support for the CaR–FA–X model was found for child and adolescent populations. Recommendations, proposals for future research and plausible explanations for the mixed findings are discussed.  相似文献

Here, we examined linguistic differences in the reports of memories produced by three cueing methods. Two groups of young adults were cued visually either by words representing events or popular cultural phenomena that took place when they were 5, 10, or 16 years of age, or by words referencing a general lifetime period word cue directing them to that period in their life. A third group heard 30-second long musical clips of songs popular during the same three time periods. In each condition, participants typed a specific event memory evoked by the cue and these typed memories were subjected to analysis by the Linguistic Inquiry and Word Count (LIWC) program. Differences in the reports produced indicated that listening to music evoked memories embodied in motor-perceptual systems more so than memories evoked by our word-cueing conditions. Additionally, relative to music cues, lifetime period word cues produced memories with reliably more uses of personal pronouns, past tense terms, and negative emotions. The findings provide evidence for the embodiment of autobiographical memories, and how those differ when the cues emphasise different aspects of the encoded events.  相似文献

Despite empirical data suggesting that commuting accidents are a major problem worldwide, research on employee behaviour while commuting by car is scant. In particular, our understanding of the antecedents of unsafe commuting behaviour is limited mainly to demographic variables and work-related physical stressors. Our study addressed this lacuna by investigating the association between work-related psychological stressors and unsafe commuting behaviour. In addition, we developed and validated a scale for measuring commuting norms and considered the permissiveness of these norms as a mediator in the stressor-commuting behaviour association. The results, based on data collected from 216 employees in a large manufacturing plant at 2 points in time, indicated that abusive supervision and work–family conflict were both positively related to unsafe commuting behaviour, and that the permissiveness of commuting norms partially mediated these relationships. The potential role of work organizations in educating employees about commuting behaviour and driving safety is discussed.  相似文献

This paper presents the results of an observation study of interactions between bicyclists and buses on shared bus lanes. The aim of the paper is to analyse bicyclists’ safety on bus lanes shared with bicyclists. Straight sections of two bus lanes shared with bicyclists in Belgium are observed. All interactions between bicyclists and buses over two full weeks are recorded and analysed. Additionally, the lateral position and riding speed of bicyclists that are in interaction with buses are compared with the behaviour of bicyclists that are not in interaction with buses. One of the observed bus lanes is in line with road design guidelines in a number of countries that state that a sufficiently narrow bus lane (<3.5 m) is hypothesised to be safer than a somewhat wider bus lane; the other observed bus lane is deemed too wide according to these guidelines and is hypothesised to lead to close overtaking manoeuvres.The results show that close interactions between bicyclists and buses are relatively frequent on both types of analysed bus lanes. Close overtaking manoeuvres (a bus overtakes a bicyclist with a lateral distance less than 1 m) as well as close bicycle-following situations (a bus drives behind a bicyclist with a time gap less than 2 s) are quite common on both analysed bus lanes. The analyses could not confirm the hypothesis that a sufficiently narrow bus lane is safer than a wider bus lane. On the contrary, close interactions seem even slightly more common on the narrower bus lane. Slightly more close overtaking manoeuvres take place on the narrower bus lane, but the difference is not statistically significant. Additionally, more bicycle-following situations take place on the narrower bus lane because overtaking is more difficult. The results show that buses often maintain a close time gap in these situations. The overtaking speed of the buses is, however, significantly higher on the wider bus lane compared to the narrower one.Moreover, the presence of a bus has an influence on the behaviour of bicyclists. Bicyclists who get overtaken by a bus ride more closely to the edge of the road than bicyclists who are not in interaction with a bus. While the road design guidelines assume that bicyclists take up a width of one meter from the edge on bus lanes shared with bicyclists, the observations show that bicyclists take up much less space while being overtaken. The presence of a bus does not have a significant influence on the standard deviation of the lateral position of the bicyclist. On the narrower bus lane, some findings suggest that bicyclists who are involved in an interaction with a bus ride faster than bicyclists who are not involved in an interaction with a bus.  相似文献
