Cognitive bias may appear in occupational therapists' interpretation of physical examinations. Since different strategies for decision making have been shown to reduce bias, its quantification is an essential first step towards awareness and bias reduction. Our aims: (1) quantify cognitive bias by testing the differences in occupational therapists' assessment of lateral pinch force modulation between young and older adults, and between women and men; and (2) to test for a correlation between the tendency to bypass an intuitive response and the degree of cognitive bias.
Occupational therapists (n = 37; age 40.3 ± 11.4 years) used a visual analogue scale to rate pre-recorded simulations of the digital output of lateral pinch modulation videos of different levels of abilities coupled with videos of young/old men/woman pressing the force sensor. They filled out the Cognitive Reflection Test and the Rational-Experiential Inventory-40.
Subjects showed higher bias towards old individuals compared to young ones ( < 0.001), but with no sex bias ( = 0.119). Rational ability correlated with cognitive bias of assessment of lateral pinch modulation in old individuals (r = 0.537, < 0.001).
Occupational therapists might underestimate the physical abilities of older adults. Biased evaluation might cause assignment of redundant exercises and therefore loss of time, effort, and resources.
认知偏差可能出现在作业治疗师对体格检查的解释中。由于已经证明不同的决策策略可以减少偏差，因此量化认知偏差是提高意识和减少偏差的重要第一步。我们的目的是：（1）通过测试作业治疗师对年轻和老年成年人以及男女之间的侧捏力调制评估的差异，来量化认知偏差；（2）测试绕过直觉反应的倾向与认知偏差程度之间的相关性。
作业治疗师（n = 37；年龄 40.3 ± 11.4 岁）使用视觉模拟量表对不同能力水平的侧捏调制视频的数字输出的预录制模拟进行评分，这些视频与年轻/老年男性/女性按压力传感器的视频相结合。他们填写了认知反射测试和理性-经验库存-40。
与年轻人相比，受试者对老年人的偏见更高（ < 0.001），但没有性别偏见（ = 0.119）。理性能力与评估老年人侧捏调制的认知偏差相关（r = 0.537， < 0.001）。
作业治疗师可能低估了老年人的身体能力。有偏差的评估可能会导致分配冗余的练习，从而浪费时间、精力和资源。
