【摘要】 目的 了解科研志愿者参与科研活动的现状及满意度，为促进本科生科研能力培养提供决策建议。 方法 以参与四川大学华西临床医学院循证医学中心及多学科综合治疗（MCQ）两项科研志愿者活动的407名同学为调查研究对象，采用自制问卷表进行调查。对数据进行描述性分析和Logistic回归分析。 结果 发放问卷407份，回收有效问卷351份，有效回收率86.24%。80.6%的受访对象对目前参与科研活动现状表示满意。认为限制工作进展的主要因素是缺乏相关基础知识和基本技能（占34.7%）以及缺乏时间（占31.6%）。21.1%的科研活动无固定的组织模式。96.2%的受访对象表示有必要进行活动成果展示。是否有导师指导、是否有知识传授和技能培训以及对活动组织模式是否满意是影响科研志愿者对科研活动满意度的主要因素（P值分别为0.027、0.011和0.000）。 结论 志愿者参与科研活动的满意度总体较高;满意度受到多种因素影响。建立科研志愿者招募体系、完善科研能力培养层次、加强科研团队组织建设、规范管理运作机制、嵌入科研课程并加强科研成果展示有助于提升本科生科研活动的参与率及满意度，对医学本科生科研能力培养具有积极作用。【Abstract】 Objective To study the current status and satisfactory degree of student volunteers’’ participation in scientific research, so as to provide suggestion for improving the scientific research capability of medical undergraduates.
