Annotation	The Outcomes and Assessment Information Set (OASIS) represents a rich opportunity for researchers interested in home health care outcomes. However, little psychometric information has been published. The purpose of this study was to provide additional psychometric data for selected portions of the OASIS using a sub-set of 201 subjects from a previously published study. Conceptual domains were identified: functional, affect, behavioural, and clinical. Reliability was evaluated using Crohnbach's alpha and the kappa coefficient for intra-rater reliability. The functional domain had the best reliability and validity. The affect and behavioural domains had adequate kappa scores, but the alphas and the factor analyses were problematic. Two of the clinical items did not perform well with kappa scores. Recommendations and suggestions for use of the OASIS are made. (KJ/RH).
