Experimental Design with Measurement Time Points. Participants are randomly allocated to either receive the ELEVATE intervention immediately (Immediate Group) or delay the intervention for 6 months (Waitlist-control Group) before they are offered the optional ELEVATE training. Children undergo monthly assessments for 12 months (including 9 months of follow-up for the Immediate Group and 3 months of follow-up for the Waitlist-control Group). Outcome measures are obtained as indicated by arrows and stars.
