PREVENTING BACK INJURIES IN HOSPITAL SETTINGS: THE EFFECTS OF VIDEO MODELING ON SAFE PATIENT LIFTING BY NURSES

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal.     

Co-localisation of abnormal brain structure and function in specific language impairment

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior frontal cortex and decreased in the right caudate nucleus and superior temporal cortex bilaterally. The unaffected siblings also showed reduced grey matter in the caudate nucleus relative to controls. In an auditory covert naming task, the SLI group showed reduced activation in the left inferior frontal cortex, right putamen, and in the superior temporal cortex bilaterally. Despite spatially coincident structural and functional abnormalities in frontal and temporal areas, the relationships between structure and function in these regions were different. These findings suggest multiple structural and functional abnormalities in SLI that are differently associated with receptive and expressive language processing.     

遗传、环境和青少年的吸烟饮酒行为：芬兰双生子研究的回溯与前瞻

本文介绍的两个“芬兰双生子（Finn Twin）”研究是对10个出生组的青少年双生子及其家庭的长期跟踪研究。本文概述了这两个项目对遗传与环境的关联和互动对吸烟饮酒行为影响的研究。这些研究的结果提示个体差异对吸烟饮酒行为的长期变动的影响受到兄弟姐妹互动、同伴互动以及父母教养方式的调节。环境对吸烟饮酒的影响主要表现在学校、居住社区与家庭环境的差异上。环境与遗传影响的程度和持久度有城乡差异。遗传的影响受居住社区的制约。多阶段模型的分析揭示了遗传与环境的互动对这些行为的演变（从试吸试饮到发展到滥用）的动态的影响,遗传似乎对吸烟饮酒的共同轨迹更有影响。这些结果对今后本项目对这约1万对芬兰成年双生子的分子遗传学研究提供了有益的线索     

Parental Awareness and Monitoring of Adolescent Internet Use

This study focused on four aspects of parental monitoring of Internet use by their children: parental supervision, communication and tracking, and adolescent disclosure. Data were obtained from a SAFT (Safety Awareness for Teens Project) national survey of Singapore youths and parents regarding Internet safety at home. Study 1 examined 1,124 adolescents and 1,002 parents; Study 2 examined a subsample of 169 dyads of adolescents and their parents. Frequency of use and engagement in risky Internet behaviors such as visiting inappropriate websites were analysed. The results indicated that parents tend to underestimate adolescents’ engagement in risky Internet behaviors and overestimate the amount of parental monitoring regarding Internet safety that occurs at home. The study suggested that mothers have a better awareness of their adolescents’ Internet use than fathers. The findings were explained in the context of parental monitoring. The results suggest that parental monitoring needs to be reconceptualized and that parents need to improve the communication with their adolescents regarding Internet use.     

共情的认知神经研究回顾

共情是指个体对他人情绪和想法的感受及理解,它在人类个体和社会的发展中起到了重要作用。近年来,脑成像技术为研究共情的神经基础提供了有力的技术支持,发现了共情的关键功能脑区。基础与临床的实验证据表明,更好地理解共情的神经机制对于孤独症、反社会人格等精神障碍有重要的意义。该文对相关的研究进行了综述并对未来可能的研究方向提出了展望     

Threat interpretation bias as a vulnerability factor in childhood anxiety disorders

The present study examined threat interpretation biases in children 7-12 years of age with separation, social and generalised anxiety disorders (N=15), non-anxious offspring at risk due to parental anxiety (N=16) and non-anxious controls of non-anxious parents (N=14). Children provided interpretations of ambiguous situations to assess cognitive, emotional and behavioural responses. In comparison with non-anxious control children and at-risk children who did not differ from each other, anxious children reported stronger negative emotion and less ability to influence ambiguous situations. These results suggest that threat interpretation bias may be a cognitive factor associated with ongoing childhood anxiety but not a vulnerability factor associated with parental anxiety.     

Trait Anger and Axis I Disorders: Implications for REBT

Anger has a prominent role in basic theories of emotion. And while many psychiatric disorders can be conceived of as emotional disorders (e.g., depressive disorders, anxiety disorders), there are no disorders for which anger is the cardinal feature. We analyzed diagnostic data on 1,687 (as later) psychiatric outpatients and looked at the co-occurrence of high trait anger (as assessed by criterion 8 of Borderline Personality Disorder) and Axis I disorders, and Borderline and Antisocial Personality Disorders. The purpose was to examine whether dysfunctional anger met criteria necessary to be considered a valid diagnostic category. Results showed that high trait anger was not fully accounted for by any particular Axis I diagnosis, or any set of Axis I diagnoses, or by the combination of Axis I diagnoses and Borderline and Antisocial PDs. Trait anger also accounted for significant amounts of unique variance in several indicators of psychiatric impairment and psychosocial functioning. We describe the anger disorder diagnoses of Eckhardt and Deffenbacher (Anger disorders: Definition, diagnosis and treatment. Taylor & Francis, Bristol, PA, 1995), and discuss the implications of those diagnoses for the practice of REBT and CBT.

自闭症谱系障碍者面孔识别的神经机制

自闭症谱系障碍（ASD）是一种心理状况的谱系障碍,其症状是社交及沟通上的广泛性异常、异常局限性的兴趣和高度重复性的刻板行为。包括自闭症、亚斯伯格症候群和待分类的广泛性发展障碍3类。研究主要以事件相关电位和功能性磁共振成像两种技术为线索,通过深入分析ASD患者在面孔识别认知过程中脑的异常变化,探讨其面孔识别障碍的神经机制问题。研究表明,ASD患者面孔识别能力的损伤主要与N170、N300、P400和Nc等ERPs成份异常及梭状回面孔区和杏仁核的低激活有关。研究推论ASD患者面孔识别障碍是多个异常脑区联合作用的结果,且主要受异常脑区的数量和损伤程度的影响。     

青少年的同伴依恋与其互联网使用的关系

青少年期同伴群体的支持逐渐超过了父母的影响.青少年期同伴依恋在青少年认知、情感、人格以及行为的健康发展和社会适应中起着重要作用,拥有亲密的同伴关系的青少年出现情感问题和行为问题的可能性更小,并拥有更健康的青少年期适应能力.该研究采用同伴依恋量表、互联网服务使用状况量表以及青少年病理性互联网使用量表对405名中学生进行了问卷调查.旨在探讨青少年同伴依恋与其互联网使用之间的关系.结果表明: (1)同伴信任与社交和娱乐服务的使用偏好呈负相关,尽管都没有达到统计显著性; (2)同伴沟通可以正向预测青少年对信息、娱乐和社交服务的使用偏好,且都达到显著性水平;还可以通过互联网娱乐服务使用偏好间接预测PIU; (3)青少年与同伴的疏离程度可以正向预测青少年对社交服务的使用偏好,也可以直接正向预测PIU.     

When your heart is in your mouth: the effect of second language use on negative emotions

Research on bilingualism and emotions has shown stronger emotional responses in the native language (L1) compared to a foreign language. We investigated the potential of purposeful second language (L2) use as a means of decreasing the experience of psychological distress. Native Swedish speakers read and answered questions about negative and neutral texts in their L1 (Swedish) and their L2 (English) and were asked to rate their level of distress before or after the questions. The texts and associated questions were either written in the same (within-language), or different languages (cross-language). We found that within-language trials when the text was written in participants’ native language (Swedish–Swedish) resulted in an increase of distress, whilst cross-language trials (Swedish–English) resulted in a decrease of distress. This implies that purposeful second language use can diminish levels of distress experienced following a negative event encoded in one's first language.
