To compare the difference in Ocular Surface Disease Index© (OSDI) scores when participants were given the OSDI to complete on their own (self-guided, SG), versus under the guidance of the examiner (examiner-guided, EG).Methods100 participants enrolled in this prospective two-visit study (fifty under-45 years old, 38F/12M; and fifty 45 years-and-older, 42F/8M). Participants who scored ≥1 on the Subjective Evaluation of Symptoms of Dryness (SESoD) were included in this study. Participants completed the OSDI SG during the first visit. Participants returned the next day and repeated the OSDI, but with EG (with standardized instructions). Participants were under deception and believed that they were comparing the OSDI to the SESoD.ResultsThe mean OSDI score of the SG and EG administration was 32.0 ± 17.3 and 33.8 ± 19.6 respectively (p > 0.05) with 95% limits of agreement between −20.6 and +24.2. The correlation between SG and EG administration was Spearman's r = 0.81, p < 0.01. The mean difference between SG and EG was not significant (p > 0.05) for both the under-45 group, and 45-and-older group. The 95% limits of agreement for the under-45 group were smaller than the 45-and-older group (under-45: [−15.5, +13.1,], 45-and-older: [−23.3, +32.2]). A significant difference was found between 8 of the 12 questions items (all p ≤ 0.01). However, the mean difference for each was <0.6 and was not considered to be clinically significant.ConclusionThere was no clinically significant difference in OSDI score between SG and EG administration, however having instructions provided with EG administration affected variability of scores in the older group more than the younger group.
