Variable | Accuracy (%) | Sensitivity (%) | Specificity (%) | Positive likelihood ratio | Negative likelihood ratio |
---|---|---|---|---|---|
CTOPP Phonological Awareness (cut-off = SS 77, PR 6) | 86 a | 86 a | 86 a | 6.00 a | 0.17 a |
Vocabulary: DELV Semantic (cut-off = SS 6, PR 9) | 71 | 86 a | 64 | 2.40 | 0.22 a |
CTOPP Nonword Repetition (cut-off = SS 6, PR 9) | 57 | 100 a | 36 | 1.56 | 0.00 a |
Note. Cut-off refers to the criterion score used to predict the presence versus absence of a response to treatment. CTOPP = Comprehensive Test of Phonological Processing–Second Edition; DELV = Diagnostic Evaluation of Language Variation; SS = standard score; PR = percentile rank. Scores at or above the cut-off predict that the child will respond to treatment, whereas scores below the cut-off predict that the child will not respond to treatment.
Desirable value.
