This paper reports on the criterion validity of the Occupational Therapy Adult Perceptual Screening Test (OT-APST) including concurrent criterion validity and its sensitivity and specificity. The performance of 208 people following stroke on the OT-APST and a reference tool (either the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) or the LOTCA--Geriatric version (LOTCA-G)) was compared. The OT-APST subscale scores and performance outcome (intact or impaired) on related subscales of the reference tool was analyzed to evaluate the concurrent criterion validity of the OT-APST and its sensitivity and specificity at selected cut-off scores. Significant correlations were found between participants' performance (intact or impaired) on the reference tool and scores on the OT-APST. The sensitivity and specificity of the OT-APST were analyzed at selected cut-off scores to explore the validity of decisions based on OT-APST performance when compared with the reference tool. This study shows that the OT-APST is a tool with demonstrated concurrent criterion validity for the assessment of visual perception.
本文报告了成人职业治疗感知筛查测试（OT - APST）的标准效度，包括同时效度及其敏感性和特异性。比较了208名中风患者在OT - APST和一种参考工具（洛温斯坦职业治疗认知评估（LOTCA）或洛温斯坦职业治疗认知评估老年版（LOTCA - G））上的表现。分析了OT - APST子量表得分以及参考工具相关子量表上的表现结果（完好或受损），以评估OT - APST的同时效度及其在选定临界值分数时的敏感性和特异性。在参考工具上参与者的表现（完好或受损）与OT - APST得分之间发现了显著相关性。在选定临界值分数时分析了OT - APST的敏感性和特异性，以探讨与参考工具相比基于OT - APST表现做出决策的有效性。本研究表明，OT - APST是一种在视觉感知评估方面具有已证明的同时效度的工具。
