Test-Retest Reliability of Assessment of Work Performance for Thai Homeless People

PurposeThis study aims to conduct test-retest reliability of the AWP - Thai version. Internal consistency has been tested after completing an approval process of forward-backward translation and achieving good content validity. Under the shortage of mental workforce, vocational rehabilitation (VR) has been trained to enhance supported employment in homeless people with mental illness (MI). The Assessment of Work Performance (AWP) is required for Thai translation to classify the quality of job skills in one pilot setting at Nonthaburis destitute home. MethodsTwo weeks were set for test-retest reliability of the AWP collecting a group of participants (n = 59). Intraclass Correlation Coefficient (ICC) was calculated at the 95% confidential level with an F-test of true value. ResultsModerate to good test-retest reliability of the AWP is addressed for all participants and separation of those participants into four groups of job selection: rug hooking, cleaning food table, sweeping the leaves, and community gardening. However, a cautious interpretation of ICC provides accurate implications of the AWP in both clinical utility and the VR program evaluation. ConclusionsThe AWP is a performance-based tool that can be an observable process in participatory work routines. Motor, process, and interactive communication skills are essential components connected to a practical solution to enhance the VR to the social welfare system.
