大学生网络交往与网络利他行为的关系:自尊与公我意识的作用

以湖北湖南三所高校大一至大四416名全日制大学生为被试,采用《大学生网络交往行为量表》、《自尊量表》、《公我意识量表》和《大学生网络利他行为量表》,对大学生的网络交往、自尊、公我意识以及网络利他行为的情况进行调查,探讨自尊是否在网络交往和网络利他行为之间起中介作用,以及这个过程是否受到公我意识的调节。结果显示：（1）网络交往对网络利他行为具有正向预测作用;（2）自尊在网络交往和网络利他行为间起部分中介作用;（3）自尊的中介效应受到公我意识的调节,即在高公我意识水平下,自尊能正向影响个体的网络利他行为;在低公我意识水平下,自尊对网络利他行为的影响不显著。研究结果有助于揭示大学生网络利他行为的形成机制,对大学生网络利他行为的干预有一定的启示意义。     

Optimizing Honor Codes for Online Exam Administration

This study examined self-reported academic dishonesty at a midsize public university. Students (N = 492) rated the likelihood they would cheat after accepting to abide by each of eight honor code pledges before Internet-based assignments and examinations. The statements were derived from honor pledges used by different universities across the United States and varied in length, formality, and the extent to which the statements included consequences for academic dishonesty. Longer, formal honor codes with consequences were associated with a lower likelihood to cheat. Results showed a significant three-way interaction and suggest how to best design honor codes.     

Long-Term Effects of an Internet-Based Treatment for Posttraumatic Stress

Abstract

Advances in communication technology offer additional strategies for providing psychological treatment. Previous trials of Internet-based treatment approaches reported significant reductions in posttraumatic stress and related symptoms in response to Internet-based treatments relative to control groups. However, empirical data on the long-term effects of those approaches are sparse. In order to evaluate the long-term effect of an Internet-based intervention, the authors conducted an 18-month follow-up of an Internet-based cognitive behavioural therapy for posttraumatic stress. Severity of posttraumatic stress symptoms was the primary outcome. Additional measures were depression, anxiety, mental and physical health, and health care utilization during the follow-up period. Treatment group participants (n = 34) were assessed 1.5 years after completing treatment. Results indicated that reductions in symptoms of posttraumatic stress symptoms, depression, and anxiety found at posttreatment were sustained during the 18-month follow-up period. Preliminary evidence on long-term effects of Internet-based health care as shown in this study is promising. However, research with larger and clinically more diverse samples is needed to fully assess the clinical impact and potential of Internet-based health care provision.     

Sleep-Related Safety Behaviors and Dysfunctional Beliefs Mediate the Efficacy of Online CBT for Insomnia: A Randomized Controlled Trial

Several trials have demonstrated the efficacy of online cognitive behavioral therapy (CBT) for insomnia. However, few studies have examined putative mechanisms of change based on the cognitive model of insomnia. Identification of modifiable mechanisms by which the treatment works may guide efforts to further improve the efficacy of insomnia treatment. The current study therefore has two aims: (1) to replicate the finding that online CBT is effective for insomnia and (2) to test putative mechanism of change (i.e., safety behaviors and dysfunctional beliefs). Accordingly, we conducted a randomized controlled trial in which individuals with insomnia were randomized to either online CBT for insomnia (n = 36) or a waiting-list control group (n = 27). Baseline and posttest assessments included questionnaires assessing insomnia severity, safety behaviors, dysfunctional beliefs, anxiety and depression, and a sleep diary. Three- and six-month assessments were administered to the CBT group only. Results show moderate to large statistically significant effects of the online treatment compared to the waiting list on insomnia severity, sleep measures, sleep safety behaviors, and dysfunctional beliefs. Furthermore, dysfunctional beliefs and safety behaviors mediated the effects of treatment on insomnia severity and sleep efficiency. Together, these findings corroborate the efficacy of online CBT for insomnia, and suggest that these effects were produced by changing maladaptive beliefs, as well as safety behaviors. Treatment protocols for insomnia may specifically be enhanced by more focused attention on the comprehensive fading of sleep safety behaviors, for instance through behavioral experiments.     

生活方式对大学生在线音乐购买意向的影响：有调节的中介模型

探讨生活方式对大学生在线音乐购买意向的影响机制。采用生活方式量表、在线音乐感知价值量表、神经质量表以及在线音乐购买意向量表对2011名大学生进行调查。结果表明：（1）时尚品味、完美主义和崇尚自由正向预测大学生在线音乐购买意向;（2）在线音乐感知价值在时尚品味与大学生在线音乐购买意向之间起部分中介作用,在线音乐感知价值在崇尚自由与大学生在线音乐购买意向之间起完全中介作用,在线音乐感知价值在中庸内敛、积极进取与大学生在线音乐购买意向之间起遮掩效应;（3）神经质调节了在线音乐感知价值对大学生在线音乐购买意向的影响。     

害羞者对模糊情境信息的解释偏向

以模糊情境句子和形容词为刺激材料,分别采用文本材料范式和改编的词汇情境联接范式,对害羞者的延时解释和即时解释偏向特点进行探讨。结果发现：害羞者对模糊情境信息不仅缺乏积极的即时解释偏向特点,而且也缺乏积极的延时解释偏向特点;害羞者未表现出消极的即时和延时解释偏向特点。研究表明害羞者可能是社交焦虑的前期阶段,对害羞者的干预可以通过引导其积极的解释偏向的方式来实现。     

网络游戏成瘾者注意焦点转换功能的特异性损伤研究

网络游戏成瘾对人类认知功能的损伤日益成为研究焦点之一。采用注意焦点转换任务,分别要求网络游戏成瘾被试与正常被试在工作记忆的语音环内、视空画板内及语音环——视空画板间进行注意焦点转换,然后比较两组被试在各转换任务中转换代价的差异,来探讨网络游戏成瘾者的注意焦点转换功能是否受损以及受损的特征。结果发现网络游戏成瘾组被试在视空画板内进行注意焦点转换时比对照组被试表现出更大的转换代价,而在其他两种转换任务中则没有发现组间差异。此结果表明网络游戏成瘾者的注意转换功能受到特异性损伤。     

心理特权与大学生网络欺骗行为：有调节的中介效应

基于有限自制力理论探讨了心理特权对网络欺骗行为的影响及作用机制,采用心理特权量表、简版自我损耗量表、内隐人格理论量表和青少年网络偏差行为量表对738名大学生进行调查。结果发现：（1）在控制性别的条件下,心理特权显著正向预测网络欺骗行为;（2）心理特权通过自我损耗的中介作用间接预测网络欺骗行为;（3）内隐人格观调节心理特权通过自我损耗预测网络欺骗行为的前半路径,具体来说,相对于渐变论的大学生,实体论大学生的心理特权更多地通过自我损耗影响其网络欺骗行为。     

Online counselling: The experience of counsellors providing synchronous single‐session counselling to young people

Kids Help Line (KHL) is a national Australian youth counselling service that provides free online and telephone counselling. This qualitative study examines the experience of 26 online KHL counsellors. Using a focus group methodology, counsellor responses were organised into categories: privacy and an emotionally safe environment; communication through text; and time. Counsellors reported the main benefit of the online environment to be emotional safety, due to reduced client emotional proximity to the counsellor, and the main disadvantage to be that reduced emotional proximity and the absence of non‐verbal cues could result in communication problems and difficulty in accurately assessing young people's concerns. Time proved a significant issue for counsellors, as the slow speed of text exchange could limit their ability to complete interventions. Methods that enhance both the process and effectiveness of online counselling are needed. Potential solutions to the challenges faced by online counsellors are discussed.     

儿童基本心理需要满足对上网行为和上网情感的影响：一项追踪研究

在自我决定理论的框架下,对467名3~5年级小学生进行为期12个月的追踪调查,以探讨儿童基本心理需要满足对其上网行为和上网情感发展的影响。结果发现：（1）3~5年级儿童的上网时间、上网积极情感和上网消极情感在一年间存在着显著减少的发展趋势;（2）基本心理需要满足能够预测上网积极情感的增加和上网消极情感的减少,对上网时间发展的预测不显著;（3）自主、胜任和关系这三个维度对儿童上网情感的发展都起着重要作用。
