This study was undertaken to confirm the effects of autogenic training (AT) on stress response and heart rate variability in nursing school students experiencing stress related to clinical training.
The study was carried out from September 2012 to April 2013 in a quasi-experimental nonequivalent control group using a pretest-posttest design. The participants were 40 nursing students in their third year at either of two nursing colleges. All consented to participate. Nineteen nursing students at one college were assigned to the experimental group and underwent the 8-week AT program, and the other 21 were assigned to the control group and did not undergo any training. Stress response was assessed by questionnaire and HRV was measured three times, that is, before the program, at the end of the program, and 6 months after the end of the AT program.
A significant time/group interaction was found for stress response (F = 4.68, p = .012), a subjective indicator. However, no significant interaction was found for the objective indicators of heart rate variability, normalized low frequency (F = 2.59, p = .090), normalized high frequency (F = 2.59, p = .090), or low frequency to high frequency ratio (F = 1.38, p = .257).
The results suggest that AT provides an acceptable approach to stress reduction in nursing students.
本研究旨在证实自生训练（AT）对因临床实习而承受压力的护理专业学生应激反应及心率变异性的影响。
本研究于2012年9月至2013年4月采用准实验非等效对照组的前测-后测设计进行。参与者为两所护理学院中40名三年级护理专业学生。所有学生均同意参与。一所学院的19名护理专业学生被分配到实验组并接受为期8周的AT训练项目，另外21名学生被分配到对照组且未接受任何训练。通过问卷调查评估应激反应，并在项目开始前、项目结束时以及AT项目结束6个月后三次测量心率变异性。
在主观指标应激反应方面发现了显著的时间/组交互作用（F = 4.68，p = .012）。然而，在心率变异性的客观指标方面，即标准化低频（F = 2.59，p = .090）、标准化高频（F = 2.59，p = .090）或低频与高频比值（F = 1.38，p = .257），未发现显著的交互作用。
结果表明，自生训练为护理专业学生减轻压力提供了一种可接受的方法。
