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.
