Gender differences have been reported to influence medical training. We investigated gender differences encountered during training in interventional radiology maneuvers.
Catheter handling was analyzed under standardized conditions in 64 participants naïve to endovascular procedures (26 women, 38 men). Objective (e.g., catheter pathway, catheter movements, required time) and subjective parameters (stress level) were recorded. The NASA-Task Load Index (NASA-TLX; 1-20 points) was used to assess participants' stress levels and perceived workload.
In the easier tasks, no significant differences between male and female participants regarding catheter handling were observed. In the most complex task, female participants took themselves more time (688 ± 363 vs. 501 ± 230 s; p = 0.02), asked for help more frequently (n = 19 vs. n = 8) and earlier than men (203 ± 94 vs. 305 ± 142 s; p = 0.049), whereas men stood out by more agitated catheter handling (6.0 ± 1.8 vs. 4.8 ± 1.6 movements/s; p = 0.005). Overall, female participants perceived tasks to be more difficult (11.5 ± 4.2 vs. 9.6 ± 3.3; p = 0.016), perceived higher stress levels (8.9 ± 4.9 vs. 6.3 ± 4.4; p = 0.037), and rated their own performance lower (9.12 ± 3.3 vs. 11.3 ± 3.3; p = 0.009). However, female participants were able to correlate self-assessed with objective parameters correctly (r between -0.555 and -0.469; p = 0.004-0.018), whereas male participants failed to correctly rate their performance (p between 0.34 and 0.73). Stress levels correlated with objective parameters in males (r between 0.4 and 0.587; p < 0.005), but not in female participants.
Perceived stress levels, self-evaluation skills, and catheter handling differ greatly between untrained male and female participants trying to solve interventional radiological tasks. These gender-specific differences should be considered in interventional radiology training.
As psychological aspects may influence individual working strategies gender-specific differences in self-perception while learning interventional radiology maneuvers could be essential regarding success in teaching and treatment outcomes.
• After performing standardized training, 38 male and 26 female volunteers showed significant differences regarding objective and self-assessed performance, as well as in perceived workload while performing simulated endovascular catheter maneuvers. • After solving simulated endovascular radiological tasks, female participants were able to self-assess their objective performance much more accurately than male participants. • Women took more time to solve simulated endovascular tasks and asked earlier and more frequently for help than men.
已有研究报道性别差异会影响医学培训。我们研究了在介入放射学操作培训中遇到的性别差异。
在 64 名对血管内手术一无所知的参与者（26 名女性，38 名男性）在标准化条件下分析导管操作。记录客观（例如导管路径、导管运动、所需时间）和主观参数（压力水平）。使用 NASA 任务负荷指数（NASA-TLX；1-20 分）评估参与者的压力水平和感知的工作量。
在较简单的任务中，男女参与者在导管操作方面没有显著差异。在最复杂的任务中，女性参与者花费的时间更长（688±363 比 501±230 秒；p=0.02），比男性更早（203±94 比 305±142 秒；p=0.049）且更频繁地寻求帮助（19 比 8），而男性的导管操作更激动（6.0±1.8 比 4.8±1.6 次/秒；p=0.005）。总的来说，女性参与者认为任务更难（11.5±4.2 比 9.6±3.3；p=0.016），压力水平更高（8.9±4.9 比 6.3±4.4；p=0.037），对自己的表现评价更低（9.12±3.3 比 11.3±3.3；p=0.009）。然而，女性参与者能够正确地将自我评估与客观参数相关联（r 值在-0.555 到-0.469 之间；p=0.004-0.018），而男性参与者则无法正确评估自己的表现（p 值在 0.34 到 0.73 之间）。男性参与者的压力水平与客观参数呈显著相关（r 值在 0.4 到 0.587 之间；p<0.005），而女性参与者则没有。
在尝试解决介入放射学任务时，未经训练的男性和女性参与者在感知压力水平、自我评估技能和导管操作方面存在很大差异。这些性别差异在介入放射学培训中应予以考虑。
由于心理因素可能会影响个体的工作策略，因此在介入放射学操作培训中，性别特异性的自我认知差异对于教学和治疗结果的成功至关重要。
在进行标准化培训后，38 名男性和 26 名女性志愿者在执行模拟血管内导管操作时，在客观和自我评估表现、以及感知的工作量方面表现出显著差异。
完成模拟血管内放射学任务后，女性参与者能够比男性参与者更准确地自我评估其客观表现。
女性参与者解决模拟血管内任务所需的时间更长，并且比男性参与者更早、更频繁地寻求帮助。
