“…For studies that reported children’s ages ( n = 80), five focused specifically on families with pre-schoolers, nine included school-aged children(Aznar et al, 2021; Chen et al, 2021; Dubois-Comtois et al, 2021; Hussong et al, 2022; McRae et al, 2021; Nyanamba et al, 2022; Ren et al, 2021; Rodriguez et al, 2021; Sun et al, 2021), 16 included adolescents and the other 50 studies included families with children in a wide age range (e.g., children under 12). Five studies investigated families where children had special needs, including children with neurodevelopmental disability (Bentenuto et al, 2021; Montirosso et al, 2021), externalising difficulties (Berry et al, 2021), Autism Spectrum Disorder (Colizzi et al, 2020), and children enrolled in a trial of preventive iron supplementation (Hamadani et al, 2020).…”
