VIDBE-Q Volume 65 Issue 3 Master's level graduate students in speech-language pathology who had completed a graduate course in speech sound disorders administered testing in non- randomized order. The first author, a certified speech-language pathologist, was present and supervised all testing. The participants completed all assessments within one session, which were approximately 45 minutes. Testing was video recorded to ensure scoring accuracy. The graduate students scored the tests during live administration and the researchers reviewed the videos for point-by-point rescoring. Responses were reviewed by the other members of the research team, and the research team reviewed and reached consensus on all items of disagreement. Results and Discussion A two-tailed Pearson correlation was calculated to determine if the AARP (mean = 3.77 SD = 5.70) and modified GFTA-2 (mean = 6.58 SD = 8.70) yielded similar results. There was a positive correlation between the scores of these two assessments, r = .971, p = < .01, n = 12. The R2 value of .94 indicates that 94% of the variance in scores on the GFTA-2 was explained by the AARP results. R2 values range from 0 to 1.0, with 1.0 indicating a perfect correlation between two measures. The R 2 of .94 in this study means that there was very little difference between the scores on the GFTA-2 and the AARP. Even though the current pilot study utilizes a small sample size, the strength of the correlation and the high
