The purpose of this study was to predict the job productivity improvement of
workers with visual impairments using self-reported rating scales for assistive
technology outcomes. The dataset to be analyzed was obtained from the raw data
included in 2013 satisfaction survey for the assistive technology provision program,
which was conducted by Employment Agency for the Disabled(KEAD). Three rating
scales to measure assistive technology outcomes(assistive technology device
satisfaction, assistive technology service satisfaction, and job performance) were
analyzed by ROC(receiver operating characteristic) curve to identify the predictability
of job productivity improvement of workers with visual impairments. The results of
these analyses were as follows. First, it was found that two rating scales for assistive
technology satisfaction could not predict the job productivity improvement of workers
with visual impairments. Second, the rating scale for the job performance could
predict the job productivity improvement of workers with visual impairments when
total measured score was 12 or more. Based on these results, the future directions of
the researches on assistive technology outcomes were suggested.
