This study explored the effects of a novel intervention, binaural beats (BB), on anxiety levels of anatomy students during cadaveric dissections and its impact on the learning environment. The study was quasi-experimental, employing a purposive sampling strategy. State (SA) and trait (TA) anxiety levels were measured using the State-Trait Anxiety Inventory during two routine dissection sessions. SA was measured at three time points: at the start, after a 3-min control (silence)/intervention (10 Hz BB) session, and at the end of the dissection. A post-study survey was distributed to the participants to obtain qualitative feedback on their perceptions of BB use during cadaveric dissections. Thirteen female students participated in this study (mean age 19.62 ± 0.65 years). Both control and intervention measures significantly reduced SA levels, with BB demonstrating a greater effect size (Hedges' g = 0.98 for intervention vs. 0.76 for control). SA decreased significantly after the BB intervention (t(12) = 3.78, p = 0.003) and remained low throughout the session, in contrast to the control session, where the reduction post-measure was not sustained (t(12) = -0.64, p = 0.54). Feedback from the post-study survey indicated that most students found the BB intervention effective in reducing their anxiety levels before the dissection. The BB intervention was effective in reducing and maintaining students' SA levels during dissection. Students reported positive experiences with BB. Further investigations are warranted to determine whether the findings of this study can be generalized to larger and more heterogeneous populations.
本研究探讨了一种新型干预手段——双耳节拍（BB）对解剖学学生在尸体解剖过程中焦虑水平的影响及其对学习环境的影响。该研究采用准实验设计，采用目的性抽样策略。在两个常规解剖课程中，使用状态-特质焦虑量表（STAI）测量状态（SA）和特质（TA）焦虑水平。SA 在三个时间点进行测量：在开始时、在 3 分钟的控制（沉默）/干预（10Hz BB）期后和解剖结束时。在研究结束后，向参与者分发了一份问卷调查，以获得他们对在尸体解剖中使用 BB 的看法的定性反馈。13 名女性学生参与了这项研究（平均年龄 19.62±0.65 岁）。控制和干预措施都显著降低了 SA 水平，BB 表现出更大的效应量（干预的 Hedges'g=0.98，而控制的 Hedges'g=0.76）。在 BB 干预后，SA 显著降低（t(12)=3.78，p=0.003），并且在整个课程中保持较低水平，与控制课程相反，在控制课程中，测量后的降低没有持续（t(12)=-0.64，p=0.54）。问卷调查的反馈表明，大多数学生发现 BB 干预在解剖前有效降低了他们的焦虑水平。BB 干预在降低和维持学生在解剖过程中的 SA 水平方面是有效的。学生报告说使用 BB 有积极的体验。需要进一步的研究来确定本研究的结果是否可以推广到更大和更多样化的人群。
