The role of psychological pain in the risk of suicide was explored using a three‐dimensional psychological pain model (pain arousal, painful feelings, pain avoidance). The sample consisted of 111 outpatients with major depressive episodes, including 28 individuals with suicidal histories. They completed the Chinese version of the Beck Scale for Suicide Ideation (BSI), the Beck Depression Inventory (BDI), the Psychache Scale, and the three‐dimensional Psychological Pain Scale (TDPPS). A structured clinical interview was conducted to assess the history of suicidal acts. Significant correlations were found among BDI, BSI, and TDPPS scores (p < .01). Stepwise regression analyses showed that only pain avoidance scores significantly predicted suicide ideation at one's worst point (β = .79, p < .001) and suicidal acts (β = .46, p < .001). Pain avoidance was also a better predictor of current suicidal ideation (β = .37, p = .001) than were BDI scores (β = .31, p < .01). Increased levels of pain avoidance during a major depressive episode may be a dominant component of the motivation for suicide. Future clinical assessments for populations at high risk of suicide should include measures of psychological pain to reduce the incidence of suicide. 相似文献

While salespeople use adaptive influence tactics in interactions with consumers, consumers can act as goal-oriented individuals attempting to manage those interactions. Prior research has documented a repertoire of consumer response behaviours, but little is known about the motivational forces. The present research examines the effects of regulatory focus on consumer behavioural tendencies in response to personal selling attempts. The findings suggest that the more promotion-focused consumers are more likely to engage in goal-seeking behaviours. This research not only addresses a void in the literature, but more importantly, sheds light on motivational antecedents driving consumer behaviours in customer–salesperson interactions. 相似文献

等值作为保证测验公平性的技术手段,一直是测验理论研究的重要方面。MIRT理论的发展证明了题目和测验是复杂的,传统的单维模型已经不能满足对人和题目/测验之间关系的探讨需求。目前MIRT等值研究主要有两种取向,其中一种取向是研究多维数据对IRT等值会产生什么样的影响;第二种取向是通过开发新的计算方法和计算工具研究MIRT等值过程。MIRT等值研究最重要的是对等值方法和过程实现的研究,目前已取得一些进展,在进行这些研究的过程中最重要的考虑因素是控制其误差影响因素。 相似文献

The present study investigated the relationship between a set of personality constructs (i.e. perfectionism, independent-interdependent self-construal, and collective self-esteem) and trait and social anxiety among 324 Mainland Chinese and 333 Caucasian college students. It was hypothesized that the strength of the correlation between these personality factors and anxiety would be different for the two samples. The results indicated that socially prescribed perfectionism was a better predictor of social anxiety for the Chinese participants, but of trait anxiety for the Caucasian participants. Independent self-construal predicted social anxiety better for the Caucasians than for the Chinese. Overall, aspects of collective self-esteem were more correlated with anxiety among the Chinese than the Caucasians. The authors argued that the findings can be used to improve multicultural counselling in China and the USA and to provide more culturally specific interventions to clients having anxiety disorders. 相似文献

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls. 相似文献

对从HSK题库中计算机自动生成试卷稳定性的试验检验 总被引:1,自引:0,他引:1
由计算机从题库中自动生成的试卷能否保持难度的相对稳定?根据IRT进行的等值误差范围有多大?为了回答这些问题,本文以共同组等值作为标准,对基于IRT之上的共同题等值误差进行了试验检验。试验中,采取一定措施保证了考生的动机水平。结果显示,IRT等值的校正方向都是正确的。在4个分测验中有3个分测验的的等值校正效果较理想,1个分测验的等值校正效果不够理想。计算机自动生成的试卷与原有人工命制的试卷在得分方面比较一致,分数相关达到0.931,获得证书的情况也是比较一致的。 相似文献

Metallic glasses exhibit low viscosity in a temperature range between the glass transition and the crystallization temperature, a feature that allows successful sintering of glassy powders. Microwave heating, being volumetric, has significant advantages over conventional heating in materials processing, such as substantial energy savings, high heating rates and process cleanliness. In the present study, we investigate the stability of Cu50Zr45Al5 glassy powders and the formation of a bulk two-component metallic glassy-crystal sample by microwave heating in a single-mode cavity (915 MHz) in an alternating magnetic field. 相似文献

当前大多数人格测量都采用的是累积式反应模型方法,该模型假设被试在测验上的得分随其能力或特质提高而增加,但是随着人格测量技术的不断发展,这一模型的实施效果遭到了质疑,研究者们开始关注展开式模型,该模型认为被试的反应取决于被试能力和项目阈值的匹配程度,当被试能力与项目阈值完全匹配时,被试做出肯定回答的概率达到最高点,称之为“理想点”,展开式模型的目的就是找到被试的理想点,从而寻找其真正的态度强度或人格特质水平。GGUM作为一种比较成熟的展开式模型,已经开始应用于人格测量的各个领域,但仍需要进行大规模的试测,在评估和预测效度方面积累经验,建立业界认可的心理测量学标准,不断探讨和开发相应的心理测量理论和简便易行的统计程序。 相似文献
