A quasi-experimental study was conducted to evaluate the effect of preoperative interviews on patients' anxiety levels. A convenience sample of 60 was assigned between two groups of equal size: a treatment group in which subjects were interviewed by a perioperative nurse or a control group in which subjects were not interviewed. All subjects completed state-trait Anxiety Inventory questionnaires. Group comparison using analysis of covariance showed subjects who were interviewed by the perioperative nurse reported significantly less anxiety than control group subjects.
进行了一项准实验研究，以评估术前访谈对患者焦虑水平的影响。选取了60名方便样本，将其平均分为两组：一组为治疗组，由围手术期护士对受试者进行访谈；另一组为对照组，不对受试者进行访谈。所有受试者均完成了状态-特质焦虑量表问卷。使用协方差分析进行组间比较，结果显示，接受围手术期护士访谈的受试者报告的焦虑程度明显低于对照组受试者。
