目的 探讨“护士长体验日”活动对心内科重症监护室护士的实施效果。 方法 于2021年1月—8月便利选取心内科重症监护室34名护士为研究对象,以提高护士自我领导力为导向,制订“护士长体验日”活动方案。对护士进行护理管理知识集中培训后,组织其参与4轮“护士长体验日”活动。体验活动前后采用修订版自我领导力量表对护士进行调查,并分析护士的活动体验。 结果 “护士长体验日”活动实施前后护士自我领导力得分分别为（119.09±16.02）分和（138.03±17.25）分,差异具有统计学意义（t=10.263,P<0.001）。活动后护士体验感受共提炼出4个主题：改善临床护理质量、自我价值得到满足、明确个人职业发展规划、提高沟通协调能力。 结论 “护士长体验日”活动的实施能够提高护士的自我领导力,但仍需进一步探究在其他科室的适用性。

Methods From January to August 2021,thirty-four nurses in the intensive care unit of cardiology department were recruited. Guided by improving nurses’ self-leadership,the activity plan of “a day as a head nurse” was finalized. After training on nursing management knowledge,nurses took part in four-round of “a day as a head nurse”. Before and after the activities,nurses were investigated by the Revised Self-Leadership Qestionnaire. The nurses’ activity experience was analyzed. Results The scores of nurses’ self-leadership before and after the activity were （119.09±16.02） and （138.03±17.25） respectively,and the difference was statistically significant（t=10.263,P<0.001）. Four themes were extracted from the interview data：improving clinical care quality,satisfied self-value,clarifying personal career development plan,and improving communication and coordination skills.
