Loneliness: Its correlates and associations with health risk behaviours among university students in 25 countries

The aim of this cross-national study was to assess factors associated with loneliness and to determine the degree to which loneliness affects health status and risk behaviours among university students. Data were collected from 17 886 university students in 25 countries (females = 58.6%, from Africa = 33.5%). In multivariable logistic regression, loneliness was predicted by lower family wealth, living in a low or lower middle income country, and antecedent childhood. Moreover, psychosocial factors of perceived lack of control, low organised religious activity, high non-organised religious activity, high intrinsic religiosity, and low social support were associated with loneliness. Lonely students were also likely to self-report poor subjective health status, sleeping problems, short sleep duration, tobacco use, heavy internet use, aggressive behaviour, injury, and sexual risk behaviour. University students with loneliness may be assisted by preventive health interventions aimed at enhancing their subjective well-being.     

Pregnancy Plans of First‐time Mothers and Their Children's Outcomes: An Examination of Mechanisms

Unintended pregnancy is prevalent in the United States and has been linked to challenges for both mothers and their children over time. However, studies have not yet identified mechanisms through which pregnancy intention is associated with children's outcomes. Identification of mechanisms among families at risk for negative outcomes will inform early clinical intervention. This current study examined the association between mothers' pregnancy plans reported during pregnancy and children's externalizing, internalizing, dysregulation, and social–emotional competence outcomes at 3 years old among an at‐risk sample of 682 first‐time mothers from the Predicting and Preventing Neglect in Teen Mothers Study. Further, this study identified mechanisms in the association that can be targeted in clinical intervention. Mediation analyses revealed that mothers' parenting stress when children were 24 months old served as a mechanism in the association between unplanned pregnancy and children's low social–emotional competence at 36 months. Implications for research and clinical practice are discussed. Specifically, early intervention with mothers experiencing unplanned pregnancies may help to promote healthy outcomes among their children over time. Copyright © 2016 John Wiley & Sons, Ltd.     

Contributions of Loss Events to Loss Distress and Trauma Symptoms in Recently Resettled Refugee Women at Risk

This research examined contributions of loss events to loss distress and trauma symptoms (accounting for trauma events) for refugee women at risk. Participants (N?=?104) responded to the Multidimensional Loss Scale (loss events and distress) and Harvard Trauma Questionnaire (trauma events and symptoms). Loss events contributed uniquely to loss distress (explaining additional 50.8% variance), and made a unique contribution to trauma symptoms (explaining additional 5.2% variance) approximately equal to trauma events. Appropriate response to psychic distress in refugee women at risk requires assessment of both loss and trauma and consideration of cultural differences in ways loss is expressed and meaning ascribed to symptoms.     

Subjective relative income and lottery ticket purchases

Despite a return of only $.53 on the dollar, state lotteries are extremely popular, especially among the poor, who play the most but can least afford to play. In two experiments conducted with low‐income participants, we examine how implicit comparisons with other income classes increase low‐income individuals' desire to play the lottery. In Experiment 1, participants were more likely to purchase lottery tickets when they were primed to perceive that their own income was low relative to an implicit standard. In Experiment 2, participants purchased more tickets when they considered situations in which rich people or poor people receive advantages, implicitly highlighting the fact that everyone has an equal chance of winning the lottery.

血管性认知功能障碍与胰岛素抵抗关系的临床研究

探讨在血管性认知功能障碍（vascular cognitive impairment,VCI）的发病机制中胰岛素抵抗（insulin resistance,IR）的作用及二者之问的关系。比较41例VCI患者与80例健康对照组中空腹血糖（FPG）等13个因素之间是否存在差异,及VCI的发生与上述各因素之间的关系。VCI组FPG、FINS、HOMA-IR、ISI、FIB、TC、TG、LDL明显高于对照组（P〈0．01或P〈0．05）;其中FINS、HOMA-IR、LDL为VCI发生的危险因素;MMSE评分与ISI呈显著正相关（rs=0．56,P〈O．01）。VCI中存在IR,IR是VCI发生的危险因素之一,VCI的严重程度与IR呈正相关。     

肾移植术后糖尿病临床高危险因素分析

探讨移植后糖尿病发生的高危因素。116例受者分为糖尿病组（22例）和非糖尿病组（94例）。对可能危险因素进行χ^2检验后显示术前肝功、糖耐量正常、术后用小量激素、CSA方案并血药浓度正常的患者糖尿病发生率低于相对应组,而性别、年龄、糖尿病家族史相比,P〉0．05。说明肝功能、糖耐量、激素量、免疫抑制剂及药物浓度是移植后糖尿病发生的危险因素。     

伴家族史的2型糖尿病危险因素的病例对照研究

为探讨2型糖尿病代谢特征及发病的危险因素,选取大连地区91例有家族史的T2DM患者为病例组,以44例患者的配偶（糖耐量正常）为对照组,进行流行病学问卷调查和体格检查,同时测定空腹血糖、空腹胰岛素、总胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白等指标,采用稳态模型法计算两组的胰岛素抵抗指数和β细胞功能指数,并进行多因素非条件Logistic回归分析。结果显示：TG、腰臀比和Ln（HOMAIR）病例组高于对照组,而Ln（HOMAβ）则病例组低于对照组,均具有统计学意义（P〈0．05）。多因素非条件Logistic回归分析结果提示,影响T2DM发病的因素有心血管疾病史、Ln（HOMAIR）及Ln（HOMAβ）。由此可见T2DM患者存在血脂代谢异常;心血管疾病史和Ln（HOMAIR）为发病的危险因素,Ln（HOMAβ）为保护因素。     

员工创新行为源于领导情感信任吗?风险倾向与组织行为授权的调节作用

领导情感信任会促进员工表现创新行为,但员工个体的风险倾向与组织行为授权可能对其具有调节作用。结果显示（1）领导情感信任能正向预测员工创新行为;（2）领导情感信任、组织行为授权与风险倾向对员工创新行为预测存在三维交互作用,相对于其他条件,组织行为授权和风险倾向均处于高水平条件下,领导情感信任与员工创新行为的正相关程度更为明显。探讨领导情感信任、组织行为授权、风险倾向与员工创新行为的关系可以为甄别影响员工创新行为的个体和环境因素提供理论指导,此外,也可为企业和直接领导如何增加员工创新行为提供借鉴。     

风险决策中的领域特异性

风险领域特异性指某特定领域内的风险决策和偏好可能会受到领域内特有的风险因素影响, 因而会导致领域特异性的行为。基于期望法则的风险决策理论认为, 风险倾向具有跨情境的稳定性。但近20年行为决策领域的证据表明, 风险倾向具有领域特异性, 其机制探索、测量工具和影响因素方面均取得了积极进展。从机制探索历程来看, 以往主流机制着重从风险−回报框架解构领域特异性的风险行为, 近年研究在丰富其机制检验证据的同时, 开始从进化、人格、动机等新的视角进行解读; 在测量工具层面, 领域特异性风险量表仍占主导地位, 并在多种文化、内容领域和群体间得到了进一步检验和扩展, 其他基于不同内容领域划分的风险领域特异性量表也具有较好的信效度; 在影响因素层面, 大量研究从遗传、环境、个体差异等角度探索了导致风险领域特异性的前因变量。未来研究方向应注重整合各风险内容领域, 在更加细化的风险领域检验现有理论, 并进一步探索个体层面的领域特异性规律。     

Parental negotiations of the moral terrain of risk in relation to young people with intellectual disabilities

This paper draws upon parental accounts from a study of the process of transition for a cohort of 28 young people with relatively severe intellectual disabilities who left special schools in 2004 and 2005 in two adjacent English localities. This paper examines how parents negotiate these boundaries and position themselves in relation to risk. A primary concern identified by parents during this transition period focuses on the risk of harm facing these vulnerable young people (whether through accidents or through sexual, emotional, physical or financial abuse) as they move into the adult world. These concerns are juxtaposed with discourses that increasingly promote the possibilities for people with intellectual disabilities to express and follow their own wishes and aspirations. For example, the policy agenda in England and Wales actively endorses the start of adult life as a time of opportunity for young people and promotes the values of independence and choice. In accounting for the management of risk in the young people's lives, we conclude that parents navigate complex boundaries between being seen to be over‐protective and ‘letting go’; between trusting others to act in the young adults' best interests and allowing these young people the autonomy to negotiate risk.
