Strong Design and Comprehensive Analysis of the Child-Parent Center Study

Arch Pediatr Adolesc Med. 2008;162(11):1099-1100. doi:10.1001/archpedi.162.11.1099

Our study of the Child-Parent Center (CPC) early intervention program1 found that participation was associated with greater health and well-being by age 24 years. In one of the editorials that accompanied our article,2 Olds criticized the study as having limited validity because it was not a randomized controlled trial (RCT). Olds advocated that only RCTs can yield valid and confident estimates of effects. Indeed, only 1 of the 14 paragraphs in the editorial discussed the actual study at all, with the rest focused on particular research questions that the early intervention field should address with RCTs.
