“…Indeed, it is highly probable that items may be of different importance (preventing metric invariance from being achieved) or that the mean scores on various items vary across different countries (preventing scalar invariance from being achieved). This goal is innovative in that it builds on studies of the validation of the CRS at the country level (Calders, 2021;Çetin & Demircan, 2023;Favez et al, 2021;Feinberg et al, 2012Feinberg et al, , 2016Galdiolo & Roskam, 2016;Luo, 2022;Mosmann et al, 2018;Nakamura et al, 2021;Pinto & Figueiredo, 2023, 2024Shai, 2019;Soma et al, 2021;Takeishi et al, 2017; see Supplemental Material) by focusing on the cross-country aspect, which is the first step to adequately compare coparenting relationships across these different contexts. In the present study, we use the full version, not the brief version, of the CRS.…”
