目的 探讨心理授权对护士职业倦怠的影响,为采取针对性措施预防护士职业倦怠提供参考.方法 采用便利抽样法于2012年3月选取北京市某三级甲等医院国际医疗部的73名护士进行问卷调查,内容包括护士职业倦怠量表、心理授权量表以及一般人口学资料.结果 被调查护士存在着中度的职业倦怠,对心理授权的认知处于中等水平;护士职业倦怠与心理授权呈负相关(P<0.01),且心理授权是护士职业倦怠的独立保护性因素.建立的多元回归方程为:护士职业倦怠=0.25×工作环境+0.79×人格特征-0.18×心理授权-0.59.结论 护理管理者在为护士营造良好的工作环境、优化员工特征与岗位匹配的前提下,应给予护士更多的自主决策权,增强护士的自我效能感、工作意义感及自主性,从而减轻职业倦怠的发生.

Objective To determine the effect of an exercise-dietary intervention on exercise-dietary self-efficacy and behavior among migrant children aged 9-12 with obesity and overweight in Beijing.Methods Thirty migrant obesity and overweight children in two schools aged 9-12 were recruited by convenience sampling method.They completed the study by the method of self-control before and after the treatment.The self-efficacy and behavior of diet and exercise are measured by self designed questionnaire.Data were obtained at five time points: baseline,one week,two months,three months and six months after the intervention.Results(1)Self-efficacy in taking healthy food and exercising improved significantly one week after the intervention(P<0.01),but there was a significant decrease two months after intervention compared with the data of one week after intervention(P<0.005);(2)Healthy diet and exercise behavior scores increased one week and three months after the intervention compared with the baseline(P<0.005),but there was a significant decrease two months and six months after intervention compared with the data of one week after intervention(P<0.005).Conclusion This study found an effect of positive changes in self-efficacy in taking healthy food and exercising,healthy diet and exercise behavior of participants who undertook an exercise and dietary intervention program,but the long term effects needed to be verified in future studies.The findings of the study show that the behavior maintaining is a long term process which needs the cooperation and supervision of the parents and their family.

Objective To describe body mass index (BMI) changes in migrant children with overweight and obesity in Beijing treated by the exercise and dietary intervention programme.Methods BMI was assessed at before and after the intervention in 30 migrant obesity and overweight children aged 9 ～ 12 in two schools from March,2010.Results BMI reduced significantly one week after the intervention ( P ＜ 0.05 ),but from two months to six months after the intervention BMI increased again to the pretreatment level( P ＜ 0.05 ).Conclusion The intervention was successful in decreasing BMI,however maintenance of BMI after treatment was not easy.The controlling of obesity and overweight is a long term process which needs the cooperation and supervision of their parents.
