Results for Research Question 3: Comparisons of key language sampling measures versus various assessment tools.
| Comparison | Percentage comprehensible comparisons (Spearman's rho) |
Outcome | |
|---|---|---|---|
| R/R2 | p values | ||
| LSC versus I-ASCC with context | .7800/.6100 | < .01* | Significant |
| LSC versus I-ASCC without context | .7300/.5300 | < .01* | Significant |
| MLUw versus MLU3 | .8300/.6900 | < .01* | Significant |
| LSC versus PPVT-4 | .0800/.0064 | .79 | Not significant |
| LSC versus TACL-3 | .0000/.0000 | 1.00 | Not significant |
| LSC versus LIPS-R | .3300/.1100 | .27 | Not significant |
Note. LSC = language sample comprehensibility; I-ASCC = Index of Augmented Speech Comprehensibility in Children; MLUw = mean length of utterance in words on the language samples, including unintelligible words; MLU3 = mean length of the three longest messages from the MacArthur–Bates Communicative Development Inventory; PPVT-4 = Peabody Picture Vocabulary Test–Fourth Edition; TACL-3 = Test of Auditory Comprehension of Language–Third Edition; LIPS-R = Leiter International Performance Scale–Revised.
