The Counseling Profession in Russia: Historical Roots,Current Trends,and Future Perspectives

Psychology was established in Russia before the Communist era. The social work profession was created in 1991 for a society in turmoil after the collapse of the Soviet Union. In 2011, the counseling profession officially emerged as a branch of social work called social psychological help. Professional counseling associations are in the formative stage. Concern about mental health issues, particularly substance abuse, suggests that the counseling profession could continue to grow in Russia.     

Temporal Relationship Between Change in Subjective Distress and PTSD Symptom Decrease During Prolonged Exposure Therapy for Posttraumatic Stress Disorder

There is growing evidence that change in distress is an indicator of change during Prolonged Exposure (PE) for posttraumatic stress disorder (PTSD). However, temporal sequencing studies investigating whether change in distress precedes PTSD symptom decline are lacking. These studies are essential since the timeline between indicators of change and treatment outcome is a key assumption for mediation. The aim of the present study was to assess the temporal relationship between within- and between-session change in subjective distress and PTSD symptom decrease. We analyzed session data from 86 patients with PTSD. Data were analyzed using dynamic panel models. We distinguished temporal effects (within-persons) from averaged effects (between-persons). Results regarding the temporal effect showed that within-session change in subjective distress preceded PTSD symptom improvement while the reversed effect was absent. Averaged within-session change in subjective distress was also related to PTSD symptom improvement. Results regarding the temporal effect of between-session change in subjective distress showed that it did not precede PTSD symptom improvement. Averaged between-session change in subjective distress was related to PTSD symptom improvement. This study provides evidence for within- but not between-session change in subjective distress as indicator of change during PE. We also found that the way of modeling potential indicators of change affects results and implications. We recommend future studies to analyze mediators during treatment using temporal rather than averaged effects.     

痛苦逃避和自我参照惩罚条件下脑电特征对自杀意念的分类效能

采用支持向量机的特征递归选择算法, 创新性采用三维心理痛苦量表和自我参照情感激励延迟任务, 建构自杀意念分类模型的重要特征集, 并比较自杀意念和抑郁的分类模型重要特征集差异。结果发现, 痛苦逃避是自杀意念分类模型的首位特征; 基于痛苦加工特征的自杀意念多模态分类模型效能优良。研究首次证实了在机器学习建构复杂的自杀意念分类模型中, 痛苦逃避及其相关脑电成分的重要性。拓展了结合心理痛苦三因素模型和机器学习算法对自杀预测的临床应用可行性。     

领导权力和地位对下属建言的影响——心理安全感的作用

通过实验研究(研究1、2)和多来源、多时点的实地问卷调查(研究3), 本文发现: 领导权力对下属建言有消极作用, 领导地位对下属建言有积极作用; 领导地位调节领导权力对下属建言的影响, 当领导地位较低时, 领导权力对下属建言的负面作用增强, 反之则不显著; 领导地位对权力的调节作用通过下属心理安全感传递至下属建言行为。这一研究结果有助于阐明组织层级差异(如权力、地位)是如何影响下属建言行为的。     

大学生网络成瘾对学业挫折感的影响:心理生活质量的中介作用

为探讨心理生活质量在大学生网络成瘾与学业挫折感关系间的中介作用,研究采用青年学生学业挫折感问卷、心理生活质量问卷和中文网络成瘾量表,对703名大学生进行测量。结果表明:(1)大学生网络成瘾与学业挫折感之间呈显著正相关,心理生活质量与网络成瘾、学业挫折感之间呈显著负相关;(2)大学生网络成瘾正向预测学业挫折感、负向预测心理生活质量,心理生活质量负向预测学业挫折感;(3)心理生活质量在大学生网络成瘾对学业挫折感影响中起部分中介作用。     

越富有越不支持再分配?——社会阶层与再分配偏向的关系及其心理机制

社会阶层是影响再分配偏向的重要因素。研究发现, 与低阶层者相比, 高阶层者再分配偏向更低。基于以往研究, 提出高社会阶层者低再分配偏向的作用机制及干预模型。依据该模型, 动机方面的经济自利与系统合理信念, 认知方面的经济不平等感知、贫富差距归因与刻板印象, 情感方面的同情心与地位焦虑是影响高阶层者再分配偏向的中介因素; 培育谦卑心态、进行反刻板印象干预、利用不平等框架效应、提高同情心、改变阶层文化价值观有助于提升高阶层者的再分配偏向。未来研究可对高阶层者的慈善行为及部分低阶层者拒绝再分配的现象加以关注, 深入考察和完善该模型的作用机制, 探索提升高阶层者再分配偏向的策略。     

Motor competence predicts self-esteem during childhood in typical development children

PurposeThe purpose of this study was to study the relationship between motor competence (MC) and self-esteem in children between 7 and 13 years of age.MethodsThis is five years mixed longitudinal study, although only the last two years were included in the analysis. Participants were N = 144 of both sexes (69 girls) divided in 6 cohorts. At baseline the youngest and the oldest cohorts had 4 and 9 years of age respectively. MC was assessed with KTK. Self-esteem and self-worth were assessed with the Portuguese version of Physical Self-Perception Profile for Children and Youth (PSPP-CY). Cross-lagged models were used to find out whether MC predicts self-esteem and self-worth, or the reverse. Linear mixed models were applied.ResultsOverall, only self-esteem was predicted by MC across age. Results show that self-esteem had a significant decrease between 7 and 13 years of age (−0.56) and that MC is positively associated with self-esteem (b = 0.006).ConclusionsMC had a mitigating effect on the decrease of self-esteem. Promoting MC during childhood and adolescence might have a positive effect on children's well-being and mental health and prevent them to dropout from physical activities.     

不同情绪载体的神经活动及其异同——脑成像研究的ALE元分析

情绪识别一直是学界关注的热点。虽然已有研究探讨了动态面孔表情、动态身体表情和声音情绪的脑机制, 但对每种情绪载体的整体认识相对不完善, 同时对不同情绪载体之间神经机制的共性和区别知之甚少。因此, 本研究首先通过三项独立的激活似然估计元分析来识别每种情绪模式的大脑激活区域, 然后进行对比分析以评估三种情绪载体之间共同的和独特的神经活动。结果显示, 动态面孔表情的大脑活动包括广泛的额叶、枕叶、颞叶和部分顶叶皮层以及海马、小脑、丘脑、杏仁核等皮层下区域; 动态身体表情的激活集中于颞/枕叶相关脑区以及小脑和海马; 声音情绪则引起了颞叶、额叶、杏仁核、尾状核和脑岛的激活。联合分析表明, 三种情绪载体跨模态激活了左侧颞中回和右侧颞上回。对比分析的结果证明了视觉刺激比听觉刺激更占优势, 动态面孔表情尤为突出, 同时动态身体表情也发挥着重要作用, 但声音情绪有其独特性。总之, 这些发现验证和拓展了三种情绪载体的现有神经模型, 揭示了情绪处理中心的、普遍性的区域, 但每种情绪载体又有自己可靠的特异性神经回路。     

子女数量与育龄母亲生活满意度的链式中介模型

为探讨子女数量与育龄母亲生活满意度之间的关系,以及教养压力和心理韧性在其中的中介作用,本研究采用教养压力问卷、心理韧性量表以及生活满意度问卷对490名小学生的母亲进行测量。结果表明：（1）子女数量与教养压力存在正相关,教养压力与心理韧性、生活满意度呈负相关,心理韧性与生活满意度正相关;（2）子女数量到育龄母亲生活满意度直接效应不显著,教养压力的独立中介效应与教养压力-心理韧性的链式中介效应显著。研究揭示了子女数量与育龄母亲的生活满意度的关系及其作用机制。
