Summary
There is some overlap between work reported in this article [1] and a previous publication by the same research group [2] that is not cited or discussed in the PLOS ONE article. The Journal of Health and Development article [2] presents the development and validation of the questionnaire which involved a cross-sectional approach, and the PLOS ONE article [1] reports a randomized interventional study that used this tool.
