Chapter 6 Online instrument creation

Selecting items for an instrument to measure early child development involves several steps. In the previous chapter (chapter @(ch:itemselection)), the most important features to be considered in selecting the items are extensively discussed. To facilitate the selection of items in practice, we have developed a web-application that can assist in selecting developmental items for an instrument. The online shiny can be reached via https://tnochildhealthstatistics.shinyapps.io/dinstrument/. A preview of the application is shown below.
