The aim of this study was to investigate whether shifting the focus to solution orientation and developing coping strategies for common errors could increase the efficiency of laparoscopic training and influence learning motivation. The concept of coping has been particularly defined by the psychologist Richard Lazarus [Lazarus and Folkman in Stress, appraisal, and coping, Springer publishing company, New York, 1984]. Based on this model, we examined the use of observational learning with a coping model for its effectiveness as a basic teaching model in laparoscopic training.
55 laparoscopically naive medical students learned a standardized laparoscopic knot tying technique with video-based instructions. The control group was only offered a mastery video that showed the ideal technique and was free from mistakes. The intervention group was instructed on active error analysis and watched freely selectable videos of common errors including solution strategies (coping model) in addition to the mastery videos.
There was no statistically significant difference between the intervention and control groups for number of knot tying attempts until proficiency was reached (18.8 ± 5.5 vs. 21.3 ± 6.5, p = 0.142). However, there was a significantly higher fraction of knots achieving technical proficiency in the intervention group after first use of the coping model (0.7 ± 0.1 vs. 0.6 ± 0.2, p = 0.026). Additionally, the proportion of blinded attempts that met the criteria for technical proficiency was significantly higher for the intervention group at 60.9% vs. 38.0% in control group (p = 0.021). The motivational subscore "interest" of the validated score on current motivation (QCM) was significantly higher for the intervention group (p = 0.032), as well as subjective learning benefit (p = 0.002) and error awareness (p < 0.001).
Using video-based learning of coping strategies for common errors improves learning motivation and understanding of the technique with a significant difference in its qualitative implementation in laparoscopy training. The ability to think in a solution-oriented, independent way is necessary in surgery in order to recognize and adequately deal with technical difficulties and complications.
本研究旨在探讨将注意力转移到解决问题的方向上,并为常见错误制定应对策略,是否可以提高腹腔镜培训的效率,并影响学习动机。心理学家理查德·拉扎勒斯(Richard Lazarus)特别定义了应对的概念[Lazarus 和 Folkman 在《应激、评估和应对》一书中,Springer 出版公司,纽约,1984 年]。基于该模型,我们考察了观察性学习与应对模型相结合作为腹腔镜培训基本教学模型的有效性。
55 名腹腔镜初学者使用基于视频的指导学习标准化腹腔镜打结技术。对照组仅提供一个掌握视频,该视频显示了理想的技术,且无任何错误。实验组接受主动错误分析指导,并观看包括解决方案策略(应对模型)在内的常见错误的自由选择视频,除掌握视频外。
在达到熟练程度之前,实验组和对照组的打结尝试次数之间没有统计学上的显著差异(18.8±5.5 与 21.3±6.5,p=0.142)。然而,在首次使用应对模型后,实验组中达到技术熟练程度的结数量明显更高(0.7±0.1 与 0.6±0.2,p=0.026)。此外,实验组中达到技术熟练程度的盲打尝试比例也明显更高,为 60.9%,而对照组为 38.0%(p=0.021)。经过验证的当前动机(QCM)的动机子量表“兴趣”在实验组中明显更高(p=0.032),以及主观学习收益(p=0.002)和错误意识(p<0.001)。
使用基于视频的学习应对常见错误的策略可以提高学习动机和对技术的理解,并且在腹腔镜培训中的实施质量有显著差异。在手术中,以解决问题为导向、独立思考的能力是必要的,以便识别和适当处理技术困难和并发症。
