公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

Police Officer Performance Under Stress: A Pilot Study on the Effects of Visuo-Motor Behavior Rehearsal

This study examined the effectiveness ofvisuo-motor behavior rehearsal(VMBR) as a method of reducing acute stress and improving police officer performance. Fifty-four recruits were randomly assigned to a treatment and a nontreatment condition prior to undergoing a highly stressful, critical event training scenario involving live fire. A manipulation check showed that participants who received VMBR displayed significantly lower scores on the cognitive state anxiety subscale of the Competitive State Anxiety Inventory-2; somatic state anxiety and self-confidence were unaffected by the VMBR treatment. Most importantly, participants in the VMBR training condition displayed better performance on the critical event scenario, including significantly more assailant hits. The findings are discussed with respect to the four-stage model of stress and human performance of Salas and colleagues.

Examination of the PC-PTSD in previously deployed Air Force Medical Service personnel

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.     

Using individual differences to predict job performance: correcting for direct and indirect restriction of range

The present study investigates the relationship between individual differences, indicated by personality (FFM) and general mental ability (GMA), and job performance applying two different methods of correction for range restriction. The results, derived by analyzing meta-analytic correlations, show that the more accurate method of correcting for indirect range restriction increased the operational validity of individual differences in predicting job performance and that this increase primarily was due to general mental ability being a stronger predictor than any of the personality traits. The estimates for single traits can be applied in practice to maximize prediction of job performance. Further, differences in the relative importance of general mental ability in relation to overall personality assessment methods was substantive and the estimates provided enables practitioners to perform a correct utility analysis of their overall selection procedure.     

Police Overestimation of Criminal Career Homogeneity

Police presumptions about criminal career trajectories have been little studied. The exploratory study reported here involved 42 police staff of varying rank and experience. Participants were asked to complete a questionnaire that asked them to predict the type of offence that an individual with a specified prior record would most probably commit next. Participating police personnel substantially overstated the homogeneity of criminal careers, that is, the nature of prior offences determined their prediction of their next offence more than available official data would deem reasonable. An incidental finding was that officers who rated the probability of further offending highest were also those who thought criminal careers most specialised. The implications for operational police decision‐making were discussed and held to be profound. Copyright © 2013 John Wiley & Sons, Ltd.     

Screening for intellectual disability in Dutch police suspects

The screener for mild intellectual disability (SCIL) was developed to screen for mild intellectual disability (IQ below 85). The aims of this study were (a) to examine the predictive validity of the SCIL in screening for intellectual disability among police suspects and (b) to explore the prevalence of cognitive intellectual disability among suspects in police custody in the Netherlands. An unselected sample of police suspects (N = 178) charged with a variety of offences was assessed with the SCIL, a Wechsler Adult Intelligence Scale (WAIS)‐III‐NL short form, and a malingering measure. The SCIL screened 50.0% of the sample as having mild intellectual disabilities, whereas the short WAIS classified 84.3% of the sample with an IQ below 85. A principal component analysis of the SCIL showed ambiguous results. Furthermore, the short WAIS classified 55.6% of our sample with a borderline IQ (IQ = 70–84), 84.3% with an IQ below 85 and 28.7% with an IQ below 70. The prevalence of intellectual disability in this sample of Dutch (police) suspects appears to be higher than prevalence rates found in previous international studies. More exhaustive research is needed to examine the prevalence of intellectual disabilities in police suspects, and the utility of the SCIL to screen for these disabilities.     

医患冲突与诚信的缺失

在新的历史条件下,医患冲突表现出更为复杂的特点,从深层次研究医患冲突的原因,诚信的缺失往往被人们所忽视。多数医疗纠纷源于医患双方缺乏诚信,以自我为中心,过分强调经济利益,缺少人文关怀。必须加强诚信道德教育,建立健全信用法律制度,使诚实守信成为人人自我约束、自觉遵守的行为规范。     

我国中医学专业课程设置发展历程研究

课程设置对人才培养质量有重要的影响作用,通过文献研究,回顾中医高等教育自1956年起的课程设置情况,全面梳理了中医学专业五年制必修课程设置情况,分为艰难开拓、全面发展、医教协同创新发展三个阶段,对2012年以后设置的中医学专业“5+3”一体化和九年制必修课程设置情况也进行了分析探讨。结果发现,随着课程体系的不断改革,必修课学时数逐渐减少,兼顾学生个性需求,注重综合能力培养;中医类课程学时数相对减少,但仍占主要课程类别;课程体系建设重点由关注课程学时数量转向关注课程质量。

     

The relationship between false confessions and perceptions of parental rearing practices

The main aim of the study was to investigate the relationship between a history of having made a false confession and reported parental rearing practices. It was hypothesized that the reporting of rejection and absence of warmth by parents would be associated with the making of a false confession. The participants were 804 college students in Iceland. Each was asked about false confessions made to teachers and parents in the past, as well as about false confessions made to the police during questioning. The participants completed questionnaires relating to perceived parental rearing practices (EMBU), proneness to antisocial behavior (the Gough Socialization Scale), personality (EPQ), self-esteem (Rosenberg), and compliance (GCS). Only eight participants (1% of those interrogated) claimed to have made false confessions to the police, whereas 10% claimed to have made false confessions to teachers or parents. False confessions were significantly associated with proneness to antisocial behavior and the EMBU Rejection and Warmth scales for both fathers and mothers.
