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
