9.4 Suggestions for better measurement

The D-score can be measured well by the instruments that are included in the current model, provided that the items that are included are corresponding to the targeted age group. In Table … an overview of the items included for each instrument per age is presented.

The D-score model enables the possibility to create new instruments that can be customized to the exact needs of the study. Population based studies may require a quick measure by less items and are targeted to a well measured population estimate for development. Whereas intervention studies need a precise estimate for the intervention and control group. At the personal level, studying one child’s development, a more precise estimation may be required. Of each of these scenarios, different instruments can be created. In our third booklet, we will discuss all of these options, and more.
