Health-Related Quality of Life Among Substance Abusers in Residential Drug Abuse Treatment

Health-related quality of life (HRQOL) in substance abusers remains an area of inquiry in need of investigation. The few studies on the topic have found substance abuser HRQOL less than that of the general population. The present research compared 303 substance abusers in long-term residential therapeutic community treatment in New York with a general non-institutionalized adult sample from New York (N = 27,465) whose data were collected between 2002 and 2006 during the yearly administrations of the Behavioral Risk Factor Surveillance System (BRFSS), a state-based system of health surveys gathering data from upwards of 350,000 adults per year across all 50 states. One sample t-tests found that the in-treatment substance abusers reported significantly more physically and mentally unhealthy days over the past 30 days, as well as significantly more inactive days over the past 30 days due to illness.     

Automatic verification of multi-agent systems by model checking via ordered binary decision diagrams

We present a methodology for the verification of multi-agent systems, whose properties are specified by means of a modal logic that includes a temporal, an epistemic, and a modal operator to reason about correct behaviour of agents. The verification technique relies on model checking via ordered binary decision diagrams. We present an implementation and report on experimental results for two scenarios: the bit transmission problem with faults and the protocol of the dining cryptographers.     

受众卷入及其对广告传播效果的影响

卷入（involvement）概念在市场研究中得到了极为广泛的关注,特别是在广告心理领域更是备受重视。研究发现,卷入常常影响广告的传播效果,制约着广告自身特点、插播环境、受众主体特征等作用的发挥。同时,学者们围绕这一概念构建了卷入的四水平说、加工深度模型、精细加工可能性模型、FCB网格、Rossiter-Percy网格等诸多理论模型。文章对相关研究进行了较系统的考察,并提出了现有研究依然存在的一些问题,如生态效度偏低、研究方法单一、相关的自动加工研究不够等     

OCCUPATIONAL HEALTH PSYCHOLOGY IN A CROSS-CULTURE PERSPECTIVE ——— An interview with Dr. Paul E. Spector

Occupational Health Psychology(OHP)is an interdisciplinary field concerned with psychological factors in employee's health,safety,and well-being,closely related to Industrial/Organizational(I/O)Psychology. Specific areas of concern are accidents,injuries,illness,stress,violence,counterproductive work behavior,and work-family conflict. Based on his research,Dr. Paul E. Spector answered our questions on aspects of Occupational Health Psychology,Cross-cultural Psychology and research/statistical methods in I/O Psychology. His opinions or suggestions about future research in I/O Psychology are informative and inspiring.     

Development and Validation of the Weekly Stress Inventory-Short Form

The Weekly Stress Inventory (WSI) has been used both in research and in clinical settings to measure minor stress. Although this tool offers a reliable and valid measure to assess minor stress, it lacks brevity that would make it more feasible for rapid assessments of stress needed in many research and clinical settings. The current study assessed the psychometrics of the newly developed Weekly Stress Inventory Short Form (WSI-SF), a 25-item scale to measure minor stress. Adults attending general medicine clinics (n = 171) at a public teaching hospital completed the WSI-SF and the WSI. The WSI-SF was found to have good internal consistency for both the events score (.92) and impact score (.91) and good convergent validity with the WSI. The results of the present study suggest that the WSI-SF is a reliable and valid instrument for use in assessing minor stress.     

The SF-36 Among Cambodian and Vietnamese Refugees: An Examination of Psychometric Properties

Among traumatized Cambodian (N=90) and Vietnamese (N=94) refugees attending a psychiatric clinic, the study examined the validity and psychometric properties of the Short Form-36 Health Survey (SF-36), a measure of self-perceived mental and physical health. In both patient samples, all eight SF-36 scales displayed excellent internal consistency (item-scale correlations and Cronbach's α). But, similar to other studies of Asian samples, (a) the Vitality (VT) scale did not separate from the Mental Health (MH) and General Health (GH) scales, as evidenced by item-scale and interscale correlations, and (b) the VT scale loaded as strongly (Vietnamese sample) or more strongly (Cambodian sample) than the MH scale on the so-called Mental Factor in a two-factor solution of the eight scales (with the GH scale also loading heavily on the same factor).     

小学儿童互选友谊的发展趋势及攻击行为的影响：3年追踪研究

对小学3、4年级的285名儿童进行了3年追踪调查,分析了儿童分别与男、女生互选友谊数的变化趋势及其在个体间的差异,探讨了外部攻击和关系攻击分别对两类互选友谊数的影响。结果表明：（1）儿童的男、女生互选友谊数在3年时间内都有显著的增加趋势,并表现出显著的性别差异,儿童与同性互选友谊数显著多于他们与异性的互选友谊数,男生与女生互选友谊数的增加速度比女生与女生互选友谊数增加速度慢,儿童与男生的互选友谊数越多,他/她与女生的互选友谊数就越少,表明了性别隔离现象的存在。（2）在控制了关系攻击的影响后,儿童的外部攻击对他们在各时间点测得的与女生的互选友谊数有显著的消极影响,而对他们与男生的互选友谊数影响不显著;在控制了外部攻击的影响后,儿童的关系攻击对他们在各时间点测得的与女生的互选友谊数有显著的积极影响,而对他们与男生的互选友谊数影响不显著。这说明外部攻击和关系攻击对儿童互选友谊数的影响存在性别差异     

人格六焦点模型及老化研究

Hooker在人格三水平理论的基础上提出了人格六焦点模型,其中3个焦点为特质、个体行为构念、生活故事,它们构成了人格结构的内在本质。另外3个焦点为状态、自我调节和自我叙述,它们是与结构相对应的加工过程。人格六焦点模型为与之相关的老化研究提供了一个解释的框架。     

因果力比较范式下对效力PC理论的检验

在用图形方式集中呈现信息的条件下,用因果力大小比较的实验范式检验效力PC理论。233名大学生被试对不同化学药物影响动物基因变异的能力做大小比较判断。结果发现,对单一因果关系因果力大小的比较判断具有以下3个特点：（1）不对称性：在预防原因条件下的因果力判断一般符合效力PC理论,而在产生原因条件下的因果力判断一般不符合效力PC理论;（2）在同时变化协变值DP和结果基率P(E|~C)的产生原因条件下,多数被试使用DP规则。这与概率对比模型的预测相一致,而不支持效力PC理论;（3）在固定协变值DP而只变化结果基率P(E|~C)的产生原因条件下,多数被试使用变异比RP规则。这是目前所有的因果推理理论都不能解释的现象。     

心理求助行为：研究现状及阶段－决策模型

回顾了国内外心理求助研究的进展和现状,指出了目前研究中存在的局限。在文献分析和前期研究基础上提出心理求助行为的阶段－决策模型,该模型将心理求助视为一个内部决策过程,包括连续的三个阶段,分别为问题知觉阶段、自助评估阶段、他助评估阶段。在不同的求助阶段,影响求助行为的因素及其影响力不同。文章简要介绍了基于这个理论模型所作的初步研究
