Table 1. Analysis of the Interclass Correlation Coefficient - ICC of items of Apraxia of Speech Rating Scale 3.5 translated into Brazilian Portuguese and cross-cultural adaptation.

ITEM ICC Confidence Interval - 95%
Lower limit Upper limit
Sound distortions (excluding distorted substitutions or distorted additions) 0.91 0.71 0.99
Distorted sound substitutions 0.88 0.64 0.99
Distorted sound additions (including intrusive schwa) 0.83 0.53 0.99
Increased sound distortions or distorted sound substitutions with increased utterance length or increased syllable/word articulatory complexity 0.87 0.62 0.99
Syllable segmentation within words > 1 syllable (Brief silent interval between syllables and/or inappropriate equalized stress across syllables) 0.94 0.80 0.99
Syllable segmentation across words in phrases/sentences (Increased inter-word intervals and/or inappropriate equalized stress across words) 0.90 0.69 0.99
Slow overall speech rate (apart from pauses for word retrieval and/or verbal formulation) 0.84 0.57 0.99
Lengthened vowel &/or consonant segments independent of overall slow speaking rate 0.86 0.59 0.99
RATE ONLY FOR AMRs (alternating motion rates, as in rapid repetition of “puh puh puh”): Slow and/or off-target (in place, manner, and/or voicing) 0= AMRs normal; 1= rare and mild, 2= frequent but mild; 3 = moderate, 4 = severe 0.92 0.74 0.99
RATE ONLY FOR SMRs (sequential motion rates, as in rapid repetition of “puh tuh kuh”): Slow (gaps within sequences), segmented (gaps between sequences), incorrectly sequenced, and/or off-target (in place, manner, and/or voicing) 0= SMRs normal; 1= any one of the listed features, 2= any two of the listed features; 3 = any three of the listed features, 4 = four of the listed features 0.93 0.75 0.99
One or both of the following: Consistently reduced words per breath group during phrase/sentence production relative to maximum vowel duration; reduced # of AMR repetitions per breath group in the absence of decreased respiratory capacity. Score on average number of syllables/repetitions per breath group across tasks: 0 = more than 7; 1= 6-7; 2 = 4-5; 3 = 3-4; 4 = 2 or less 0.87 0.62 0.99
Silent articulatory groping 0.91 0.70 0.99
Audible false starts/restarts or groping including sound repetitions, excluding fillers and unambiguous semantic false starts (e.g., spoo…fork) 0.88 0.64 0.99
Total 0.85 0.78 0.90
