Application of cognitive interview in the construction of Workplace Violence Management Ability Scale for Psychiatric Nurses

目的探讨认知性访谈在精神科护士工作场所暴力管理能力量表构建中的应用。方法基于4R危机管理理论、半结构式访谈、专家咨询形成初版精神科护士工作场所暴力管理能力量表。于2022年4月—6月,采用目的抽样法,选取广州市某精神专科医院的24名精神科护士作为访谈对象,共进行了3轮认知性访谈,了解目标人群对于量表的理解程度及建议,并进行研究团队的讨论修订。通过便利抽样法,于2022年7月—9月,选取453例在广州市某精神专科医院工作的精神科护士进行量表测量学检验,并形成最终版量表。结果第1轮认知性访谈对存在疑义的8个条目进行讨论修改;第2轮访谈对1个有疑义的条目进行修订;第3轮认知性访谈所有受访者均能正确理解条目内容且无疑义。最终版量表包括44个条目,6个维度,量表总的Cronbach’sα系数为0.983,平均内容效度指数为0.969,具有良好的信效度。结论通过认知性访谈,了解了精神科护士对于量表的理解程度,对量表中难以理解、不舒适、不相关的表述进行了修改,极大提高了量表的科学性与准确性。
