Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A latent language variable created from the four individually administered language tests (CELF 4 Recalling Sentences; CELF 4 Formulating Sentences; CELF 4 Understanding Spoken Paragraphs; Renfrew Action Picture test - Information and Grammar) measured at pretest (baseline) in December 2021 and at posttest (on completion of the 20-week intervention in June/July 2022) | — |
Secondary
| Measure | Time frame |
|---|---|
| Measured at pretest (baseline) in December 2021 and at posttest (on completion of the 20-week intervention in June/July 2022): 1. A latent language variable created from the four LanguageScreen subtests (Receptive Vocabulary, Expressive Vocabulary, Listening Comprehension and Sentence Repetition) 2. A latent language factor based on the four individually administered language tests (CELF 4 Recalling Sentences; CELF 4 Formulating Sentences; CELF 4 Understanding Spoken Paragraphs; Renfrew Action Picture test - Information and Grammar) 3. A latent variable of expressive writing based on the Writing Assessment Measure (WAM) involving measures of sentence structure and grammar, organisation and planning, vocabulary and ideas. 4. A latent variable for arithmetic skills based on one minute addition and subtraction tests (TOBANS) 5. Two observed variables assessing bespoke taught vocabulary (i.e. a measure of the understanding of words directly taught in the intervention) and bespoke untaught vocabulary (i.e. a measure of the understanding of words of similar difficulty to the bespoke taught words, but which have not been directly taught in the intervention) | — |
