This study aimed to investigate the effects of revising PROMs to within the recommended RGL for health-related materials. Three published PROMs were revised to within the recommend levels, according the F-K readability formula, and were trialed on experienced HA users in audiology clinics, in comparison with the original versions of PROMs. The scores of the revised versions were analyzed and compared to those of the original versions, and also compared to a second copy of the revised version in order to assess test-retest reliability. It was hypothesized that the scores derived from the revised PROMs would be significantly different to the scores derived from the original versions, and also that the scores from the repeated revised version would not be significantly difference to the initial revised administration of the PROMs. The results, statistically, were largely
inconclusive, with some sections appearing to support both hypotheses, some only supporting one hypothesis of the two, and one section that supported neither, based on statistical
significance. This which was most likely due to the large number of participants, and
subsequent overpowering of the study. However, the trends in the data were very supportive of both hypotheses, with the majority of the sections revealing a large difference between the means of the score of the original and revised versions, and a very small difference between the two administrations of the revised version.
Though the results are statistically murky, and underscore the need for future research, the trends revealed by this study are encouraging in regard to the hypotheses. The results are a preliminary indication that if PROMs are revised to within the recommended
54
levels for health-related materials, then clients will give more clinically valid, consistent answers than what they do with the current versions.
Boothroyd (2007) insists that in the interest of achieving an optimum result for patients, sensory management cannot be relied on by itself. Similarly, the implications of a patient misunderstanding health-related information are serious (Wang et al., 2013), and therefore significant consideration should be given to the revision of PROMs, even on this basis alone. In the interest of continuing the trend of becoming more patient orientated (Cox, 2005; Gilligan & Weinstein, 2014), and taking into account the implications to the client’s
