“…As with older children, parents tended to report more problems than did teachers (Berg-Nielsen et al, 2012;Dinnebeil et al, 2013;Grietens et al, 2004;Korsch & Petermann, 2014;Kuschel, Heinrichs, Bertram, Naumann, & Hahlweg, 2007;Winsler & Wallace, 2002). With regard to social skills or prosocial behavior, overall agreement was modest, too, and parents tended to rate their children more positively than did teachers (Dinnebeil et al, 2013;Schönmoser, Schmitt, Lorenz, & Relikowski, 2018;Winsler & Wallace, 2002). However, there is nothing known about interrater agreement when assessing young children's developmental status.…”
