流动儿童与城市儿童情绪调节策略对自卑感影响的比较

目的运用倾向得分匹配(propensity score matching,PSM)方法,比较流动儿童与城市儿童情绪调节策略对自卑感影响的差异。方法应用情绪调节策略问卷、自卑感量表进行团体施测,调查9~17岁流动儿童和城市儿童953名;再运用PSM方法,对流动儿童与城市儿童进行匹配,得到流动儿童与城市儿童各225名,对其情绪调节策略、自卑感进行方差分析、回归分析的比较。结果 PSM后流动儿童与城市儿童自卑感差异有统计学意义(t=2.143,P0.05,d=0.25),流动儿童与城市儿童的P-宣泄(t=2.155,P0.05,d=0.20)、N-重视(t=2.060,P0.05,d=0.20)、P-原因(t=2.069,P0.05,d=0.21)以及N-原因(t=2.248,P0.05,d=0.21)等情绪调节策略差异有统计学意义。方差分析显示,城市儿童P-反应[F(1,10)=2.223,P=0.019,η~2=0.129]、N-反应[F(1,17)=2.321,P=0.005,η2=0.227]等情绪调节策略对自卑感主效应均有统计学意义。回归分析显示,流动儿童与城市儿童的N-重视、N-宣泄、N-反应、N-原因以及P-忽视、P-抑制、P-反应等情绪调节策略对自卑感的正向关联都有统计学意义(β=0.148~0.435,均P0.05),流动儿童的P-重视情绪调节策略对自卑感的负向关联有统计学意义(β=-0.131,P0.05)。多元逐步回归分析显示,按照具体调节方式来看,流动儿童仅有N-重视、N-宣泄情绪调节策略对自卑感的正向关联具有统计学意义,可解释变异率为21.4%;城市儿童有N-重视、N-宣泄、P-抑制情绪调节策略对自卑感的正向关联具有统计学意义,P-重视情绪调节策略对自卑感的负向关联具有统计学意义,总的可解释变异率为26.3%。按照原因反应调节方式来看,流动儿童仅有N-反应、N-原因情绪调节策略对自卑感的正向关联具有统计学意义,可解释变异率为13.0%;城市儿童有N-反应、P-反应情绪调节策略对自卑感的正向关联具有统计学意义,可解释变异率为15.0%。结论流动儿童情绪调节策略倾向于使用原因调节(或忽视、重视),而城市儿童倾向于使用反应调节。

Influence of VDT (visual display terminals) work on eye accommodation

Visual display terminals (VDT) are popular in offices. Many VDT operators have complained about eye-function impairment. Experiments using an accommodo polyrecorder and an infrared optometer showed that visual tasks in VDT work might induce temporary effects in the visual accommodation system; prolonged the near point distance and the contraction time of accommodation and increased the low frequency component of the small fluctuation of accommodation after VDT work. The inhibition of accommodation caused by VDT work was more severe than that caused by the conventional hard-copy work, and changes in the accommodative function were found with statistical significance in the smaller-size character group but tended to deteriorate in the larger-size character group. The inhibition was more evident in the elderly and middle age groups than in the young age group. The inhibition of accommodation by VDT work might be inhibited by administration of methylcobalamin.     

Workplace Accommodation as a Social Process

Successful sustained employment for people with disabilities is a function of a complex array of factors. Key among these factors is appropriate accommodation at the workplace. Current approaches to accommodation, however, are often unsuccessful. Research suggests that this is due, in part, to the limited view of accommodation as technical changes to the job. An approach to accommodation that does not take into account the social context ignores the consequences of the process on work group morale and individual self-esteem and well-being. This has repercussions for individual job performance, job satisfaction and work retention, as well as overall work group productivity. An intervention was designed to take into account the social nature of the accommodation process and pilot tested with 12 workers who were out on a short term disability leave with a psychiatric diagnosis and their work groups. Based on a psychoeducational model, the intervention educates the work group about what it means to work with a disability, provides a safe environment where the worker with disability and coworkers can share concerns about the impact of accommodation on the group, informs about the accommodation process and specifies strategies to help the worker with disability best meet job requirements. Key intervention components include 1) the development of a disclosure plan since workplace intervention cannot occur without disclosure, 2) a systematic method for identifying the work group members, 3) a formal psychoeducation training that includes the supervisor, identified work group members, and the individual in the work organization who has the authority to approve accommodations, and 4) on-going follow up support to the supervisor and worker with disability. Although generalizability of the findings is limited because of the small sample size and its application only to those with mental health conditions, they support the importance of this approach to employment outcomes for people with disabilities. First, findings suggest that the rehabilitation process cannot stop at placement. Providers must be willing and able to enter the workplace with their clients. This requires providers to take on new roles such as educators, interpreters, negotiators and trainers. Disclosure must lose its status as a taboo topic. Providers and workers with disabilities must come to understand the risks and benefits of disclosure, and, when the decision is made to disclose, must have a formal, structured plan for carrying it out. Finally, workplace intervention must take into account the social context and provide the opportunity for communication and interaction in order to insure the success of the accommodations.     

视频显示终端作业人员眼调节幅度调查及影响因素分析

目的了解视屏显示终端(VDT)作业人员的眼调节幅度状况,为VDT作业人员保护眼睛,预防与VDT作业相关的眼睛损伤提供依据。方法对596名5年以上VDT作业人员和572名对照者进行问卷调查和眼科检查,采用SPSS 11.5软件进行单因素分析以及直线回归模型分析。结果视屏显示终端作业者眼调节幅度较对照组降低,差异有统计学意义(P<0.01),年龄、工龄、每周工作时间、屈光状态、屏幕类型5个因素是VDT作业人员的调节幅度下降的重要易感因素。结论 VDT作业可使作业者眼调节幅度下降,屈光不正者从事VDT作业更容易引发调节幅度下降。而且有随作业人员工龄、每周工作时间的增长加重趋势。     

Generating Workplace Accommodations: Lessons Learned from the Integrated Case Management Study

Modified duty and other accommodations by employers have been shown to be helpful in managing workplace disability associated with injuries and illnesses. Benefits of accommodation have been attributed to both reduced physical and psychosocial exposures. Although many employers have adopted proactive return to work policies that emphasize temporary work modifications, standardized methods for specifying appropriate accommodations have been elusive. On the basis of the experiences and results of a randomized controlled study of case management services for work-related upper extremity disorders, we describe issues pertaining to the application of self-report measures of function and exposure assessment for generating accommodations. Challenges of this approach are 1) including specific work tasks on measures of physical function; 2) improving concordance between ergonomic exposure categories and methods of accommodation; and 3) providing a structured process for negotiating employee and employer preferences. To improve the effectiveness and efficiency of accommodation efforts, new tools for assessing function and ergonomic exposures in the workplace should be developed to specify accommodations more directly.

Service user experiences of specialist mental health supported accommodation: A systematic review of qualitative studies and narrative synthesis

Specialist supported accommodation services have become a key component of most community‐based mental healthcare systems. While mental health policies highlight the importance of service user involvement in service development and care planning, there are no comprehensive literature reviews synthesising services users’ perspectives on, or experiences of, supported accommodation services. This systematic review was undertaken to fill this gap. We searched electronic databases (January 2015, updated June 2017), conducted hand searches and used forward‐backward snowballing to identify 13,678 papers. We inspected the full‐text of 110 papers and included 50 of these in the final review. Data extraction and quality assessments were conducted. We used narrative synthesis to develop a conceptual model of service users’ experiences that included structural, process, relational and contextual factors, such as the characteristics of the service, relationships with staff and other service users, the intensity and nature of support, the physical environment, and social and community integration. The review highlights the complex interplay of individual, service‐level and community factors in shaping the lived experience of service users and their impact on personal identity and recovery. Our approach addressed some of the widely reported limitations of the quantitative research in this field, providing a conceptual model relevant to service user experiences across supported accommodation service types, population groups and countries.
