Measurement Properties of the Stroke-Predischarge Occupational Therapy Assessment.

There is no comprehensive predischarge occupational therapy assessment tool in South Korea. The objective of this study was to determine Stroke-Predischarge Occupational Therapy Assessment (S-POTA) validity and reliability. Twenty-seven occupational therapists (OTs) assessed 97 patients with stroke. Concurrent validity was evaluated by comparing S-POTA scores with stroke-specific quality of life (SS-QOL). Discriminant validity was evaluated by comparing S-POTA scores between outpatient and readmitted groups, and a receiver operating characteristic analysis was conducted. The test-retest was conducted twice in 20 patients, and the inter-rater test was conducted with two OTs per patient. S-POTA positively correlated with SS-QOL. S-POTA rating differs significantly across outpatients and readmitted groups. All S-POTA areas under curve values ranged from .70 to .85, and cut-off points were derived. Cronbach's α for internal consistency was .953, the intraclass correlation coefficient for test-retest was .990, and .987 for inter-rater reliability. The results suggest S-POTA is a reliable tool for efficient implementation of discharge planning.
