CONSTRUCT VALIDATION AND RELIABILITY ANALYSIS OF THE SELF-ASSESSMENT OF OCCUPATIONAL FUNCTIONING INSTRUMENT FOR DEAF PEOPLE IN THE BRAZILIAN SIGN LANGUAGE

Abstract

ABSTRACT Objective: to assess construct validity and reliability of the Self-Assessment of Occupational Functioning Scale in its Brazilian Sign Language version with deaf people. Methods: a methodological research study, with a sample of 121 deaf individuals, conducted virtually from January 2018 to July 2019 with dissemination throughout Brazil. Collection took place from the Self-Assessment of Occupational Functioning Scale in its transculturally adapted version for the Brazilian Sign Language. For the analysis of construct validation, the Student's t test for independent samples was used, while internal consistency was tested with the Kuder-Richardson test. Reproducibility was analyzed by means of the test-retest technique, using the McNemar test for the items and the Intraclass Correlation Coefficient and Pearson's correlation coefficient for the scores of the domains. Results: the Self-Assessment of Occupational Functioning Scale, in its version in Brazilian Sign Language, showed to be valid and reliable for the sum of the scores, and the mean of the domains obtained good internal consistency both in the total score (0.89) and for the items of the instrument. Conclusion: the instrument showed to be valid and reliable for deaf people. Offering a validated instrument to deaf individuals may provide this collective with the opportunity to expose their needs or demands regarding occupational functioning, allowing both health professionals and researchers in the area to plan care and research studies in a more inclusive and targeted manner, enabling benefits for the deaf.
