The level of psychiatric morbidity and perceived sources of stress among police officers were investigated using the General Health Questionnaire (GHQ) and a stress situation questionnaire, which were sent to 171 officers. Half of the responders were invited to attend group counselling sessions weekly for 12 weeks. Outcome measures studied were a second GHQ completed at the end of the treatment period and the amounts of sick leave taken in the 12-week period before, during and after the treatment period. The results were that 61 people returned the first GHQ of whom 59 were male and of whom 14 were classed as ‘cases’. Of the 31 assigned to the treatment group, 22 attended at least one session. Responses to the stress situation questionnaire and the content of counselling sessions tended to confirm the impression that internal aspects of the organization were viewed as prime sources of stress and dissatisfaction. There were no significant changes in GHQ score within or between groups, nor were there significant differences in the amount of sick leave taken. Nevertheless the sessions appeared to be valued and we conclude that this sort of intervention is at least feasible. We recommend that similar studies measure psychiatric morbidity during treatment and at follow-up, rather than immediately after finishing, when reactions to this termination are prominent. 相似文献

The graduate nurse year requires individuals to make a huge transition from university student to registered nurse as part of the health care workforce. New graduates experience steep learning curves throughout the first year of professional practice. This study sought to explore experiences and learning occurring throughout the graduate nurse program for a group of seven new nurse graduates. Focus group interviews were conducted at six months and 12 months into the program using the same set of guiding questions. The first interview highlighted that graduates early in the graduate year were internalised, concentrating on their own survival in managing workloads, facing practice realities and coming to terms with themselves as nurses. Learning was primarily about survival strategies and performing tasks. By the second interview, graduates were much less focussed on themselves. They understood their place in the health care team, had gained confidence in their relationships, and were showing concern for the next graduates arriving. Learning at this stage involved more higher order skills, including critical thinking. 相似文献

Yasushi Sano Hirohisa Machida Kuang‐I. Fu Hiroaki Ito Takahiro Fujii 《Digestive endoscopy》2004,16(Z1):S93-S96
The goal of endoscopic mucosal resection (EMR) is to allow the endoscopist to obtain tissue or resect lesions not previously amenable to standard biopsy or excisional techniques and to remove malignant lesions without open surgery. In this article, we describe the results of conventional EMR and EMR using an insulation‐tipped (IT) electrosurgical knife (submucosal dissection method) for large colorectal mucosal neoplasms and discuss the problems and future prospects of these procedures. At present, conventional EMR is much more feasible than EMR using IT‐knife from the perspectives of time, money, complication, and organ preservation. However, larger lesions tend to be resected in a piecemeal fashion; and it is difficult to confirm whether EMR has been complete. For accurate histopathological assessment of the resected specimen en bloc EMR is desirable although further experience is needed to establish its safety and efficacy. Further improvements of in EMR with special knife techniques are required to simply and safely remove large colorectal neoplasms. 相似文献

实习期医学生心理健康状况、应对方式及压力状况的调查 总被引:2,自引:1,他引:1
目的探讨实习期医学生心理健康状况、应对方式及压力状况。方法将进入临床实习期的364名临床医学生作为研究组,而选取379名非实习期的临床医学生作为对照组,问卷评定采用症状自评量表(SCL-90)、应对方式问卷及心理身体紧张松弛测试表。结果研究组SCL-90的人际关系敏感、强迫、抑郁、焦虑、敌对因子得分显著高于对照组(t=2.25~5.17,P<0.05);与对照组相比,研究组的应对方式中解决问题因子分有显著性降低,自责、退避因子分则有显著性增高(t=-1.97~2.89,P<0.05);研究组的心理压力状况明显差于对照组,且差异具有显著性意义(χ2=56.03,P<0.05)。结论实习期的临床医学生存在不同程度的心理问题,应予以足够重视。 相似文献
