Relationship between type D personality and post-traumatic stress disorder symptoms in survivors after the Zhouqu debris flow disaster

目的探究D型人格对舟曲泥石流幸存者创伤后应激障碍症状的影响。方法在泥石流灾难发生1年后,在甘肃省甘南自治州舟曲县的幸存者中随机抽样进行问卷调查,使用自编背景资料调查问卷、创伤后应激障碍筛查清单(PCL&mdash;S)和D型人格量表(DS14)中文版来了解幸存者的创伤暴露状况、创伤后应激障碍(PTSD)症状、心理特征和人格特质。结果D型人格在舟曲地区幸存者中分布比例为51.17%,显著高于荷兰普通人群(21%)和中国大学生群体(31.1%)。具有D型人格的幸存者PTSD症状更严重。主观创伤、泥石流造成的经济损失和消极情感(NA)是D型人格幸存者PTSD症状的显著预测因素。结论D型人格与幸存者PTSD症状具有正性关系,可能是PTSD症状的一个易感因子</p

Psychometric Equivalence Between Mobile Phone Based and Paper-and-pencil Tests： A Case with Children’s Revised Impact of Event Scale

目的：以儿童版事件冲击量表为例考察手机测验和纸笔测验的心理测量学等值性。方法：在四川绵竹市某中学对334名初中学生施测手机版本和纸笔版本的儿童事件冲击量表（CRIES-13）,并考虑平衡顺序。应用经典测验理论和验证性因素分析取向对跨测验模式的等值性进行检验。结果：两种框架下的分析均得出量表具有较好的信度和结构效度,除个别条目外,在条目水平和量表水平上均存在很高的跨测验模式的等值性。结论：结果初步支持手机平台用于心理测验的测量学的可靠性以及与纸笔测验的等值性

A study of influences of perceived social support and social evaluations on adultslife satisfaction after the earthquake

目的探讨玉树震后灾民的领悟社会支持、社会评价(对他人、政府与社会组织的信任度、对政府与社会组织的满意度和对灾后救灾重建工作的满意度)对灾民生活满意度的影响。方法用领悟社会支持量表(PSSS)、生活满意度量表(SWLS)和自编问卷对370名青海省玉树藏族自治州地震灾区的成年人进行测量,平均年龄(32.99&plusmn;12.66)岁。结果①朋友支持(r=0.24,P〈0.01)、他人支持(r=0.15,P〈0.01)、对他人、政府与社会组织的信任度(r=0.19,P〈0.01)、对政府与社会组织的满意度(r=0.14,P〈0.05)和对救灾重建工作的满意度(r=0.17,P〈0.01)都与生活满意度有显著正相关。②朋友支持(&beta;=0.21,P〈0.01)和对他人、政府和社会组织的信任(&beta;=0.20,P〈0.05)能显著预测被试的生活满意度。结论朋友支持和对他人、政府与社会组织的信任度是影响震后玉树灾民生活满意度的重要因素。</p

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
