Design outcomes

Primary

Measure	Time frame
1. Parent responsiveness measured by the Parent Responsiveness Rating Scale (PaRRiS) (score 1-5) (ordinal) at baseline, outcome and follow-up 2. Parent responsiveness measured by a detailed measure of 4 parental responsive behaviours (interval) at baseline, outcome and follow-up 3. Parent use of behavioural techniques by coding using the behaviour change technique taxonomy (BCTT) (percentage out of the number of techniques taught, e.g. if 5 techniques, and only used 1, the score would be 1/5=20%) (interval) measured at baseline, outcome and follow-up Assessment points: • one pre-intervention assessment point (baseline: maximum 4 weeks before the intervention begins) • two post-intervention assessment points (outcome: within 2 weeks of finishing intervention, and follow-up: 6 weeks post-outcome assessment)	—

Secondary

Measure	Time frame
1. Parent’s understanding of their role in their child’s language development and intervention, measured by 5-point Likert scale questionnaire at baseline and outcome 2. Children’s communication development, measured by the Focus on the outcomes of children under 6 (FOCUS-34), at baseline, outcome and follow up 3. Children’s language use, measured by the MacArthur-Bates Communication Development Inventory (MB-CDI) AND their Mean Length of Utterance (MLU) as taken from 10 minutes of video recording at baseline, outcome and follow-up Assessment points: • one pre-intervention assessment point (baseline: maximum 4 weeks before the intervention begins) • two post-intervention assessment points (outcome: within 2 weeks of finishing intervention, and follow-up: 6 weeks post-outcome assessment)	—
