To determine if passing or failing statistically-based validity criteria during a distraction-based hand strength assessment is related to test behavior during a lifting assessment.
200 consecutive clients presenting for an FCE.
The two testing protocols, one involving a hand strength assessment, the other involving an assessment of lifting capacities, were administered to assess the variability between repeated measures.
Clients failing two or more statistically-based hand strength validity criteria had significantly more variability between repeated measures in the lifting assessment, p=0.001 and 0.014 for right and left unilateral lifts, respectively, and p<0.0005 for three different bilateral lifts.
A pattern of performance related to the degree of variability in repeated measures protocols for these two distraction-based protocols is revealed. Passing or failing the hand strength assessment are each equally predictive of test outcome during the distraction-based lifting assessment. The failure of the validity criteria in these two distraction-based tests cannot be attributed to a history of surgery but, rather, is the result of abnormal test behavior.
确定在基于分心的握力评估中通过或未通过基于统计的有效性标准是否与举重评估期间的测试行为相关。
连续200名前来进行功能能力评估（FCE）的客户。
实施两种测试方案，一种涉及握力评估，另一种涉及举重能力评估，以评估重复测量之间的变异性。
未通过两项或更多基于统计的握力有效性标准的客户在举重评估中的重复测量之间的变异性显著更大，右侧和左侧单侧举重的p值分别为0.001和0.014，三种不同双侧举重的p值<0.0005。
揭示了与这两种基于分心的方案的重复测量方案中的变异性程度相关的表现模式。在基于分心的举重评估中，通过或未通过握力评估对测试结果的预测能力相同。这两种基于分心的测试中有效性标准的未通过不能归因于手术史，而是异常测试行为的结果。
