Data Analysis: All families will be included in an intention-to-treat (ITT) analysis irrespective of uptake of intervention using the group median score for those lost to follow-up to eliminate the effects of a severe outlier presented in the data (High, 2005). These results will be compared to those who adhered strictly to the protocol in a per protocol (PP) analysis. To check for demographic differences, we will run baseline and attrition analyses.
