Thank you for your comment, we want to make the definition of this index as clear as possible and we have edited this in section 2.5.1 and included the sub-components, lines 193-196. We have also cited that reference in both sections 2.5.1 and 2.5.2 so that readers can find a more detailed description. We have also edited section 2.5.2, lines 215-225 so that the RADDS index is also easier to understand and have mentioned some of the sub-components.
The Swedish Healthy Eating Index for Adolescents 2015 (SHEIA15) is not well explained in this paper. The following paper did a better job of reporting it Moraeus L, Lindroos AK, Warensjö Lemming E, Mattisson I. Diet diversity score and healthy eating index in relation to diet quality and socio-demographic factors: results from a cross-sectional national dietary survey of Swedish adolescents. Public Health Nutr. 2020 Jul;23(10):1754-1765. doi: See their Table 5.
