Abstract

OBJECTIVE. The Árnadóttir OT-ADL Neurobehavioral Evaluation (A-ONE) is a standardized assessment that links performance in activities of daily living (ADL) to neurobehavioral impairments. This study tested the construct validity of the A-ONE.

METHOD. From two hospitals in Iceland, 42 patients between 45 and 87 years of age who had sustained either a right or a left cerebrovascular accident (CVA) were evaluated on the Functional Independence Scale (FIS) and Neurobehavioral Specific Impairment Subscale (NSIS) of the A-ONE. The Mann Whitney U test and chi-square test were used to explore possible differences between the performance of participants with left and right CVA. Descriptive statistics were calculated for demographic data and for items on the FIS and NSIS. The level of significance was set at p < .05.

RESULTS. Three of 18 ADL items observed on the FIS and 13 of 46 items on the NSIS discriminated at a statistically significant level between the left and right CVA groups.

CONCLUSION. The results provide minimal support for the construct validity of the A-ONE related to differentiating between ADL performance of persons with left and right CVA. However, results regarding the ability of the A-ONE to detect and lateralize impairments agreed with literature regarding lesion sites for the impairments.
