THE DEVELOPMENT OF THE RELAPSE RISK ASSESSMENT SCALE FOR NON- INCARCERATED DRUG ADDICTS

目的：编制非强戒期毒品成瘾人员复吸风险评估量表，并检验其信度和效度。方法：以生理-心理-社会多元模型为理论依据，在文献调研、个别访谈和专家研讨等基础上，从生理（稽延性症状、强迫性）、心理（负性情绪、错误认识）和社会（线索暴露、社会支持）三方面6个维度构建复吸风险评估初始量表，通过预测试形成最终量表。随后对269名非强戒期毒品成瘾人员进行正式测试。结果：总量表的内部一致性Cronbacha系数为0．952，各维度的α系数在0．778—0．952之间。验证性因素分析的结果支持6维度的结构（r／df=1．89，RMSEA=0．058，GFI=0．91，CFI=0．99，NFI=0．98，IFI=0．99）；量表各维度得分与“16项复吸原因问卷”相关维度的得分呈正相关。结论：该量表具有良好的信度和效度，可以作为非强戒期毒品成瘾人员复吸风险的评估工具

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
