“…Studies of children's social networks have often relied on children's self-report, most commonly with a peer-nomination task (e.g., Parkhurst & Asher, 1992). However, the use of teacher-report instruments can be valuable when working with younger children or children with disabilities, who may not be reliable informants of their interactions with others (Lin, Justice, Paul, & Mashburn, 2016). Preschool teachers are recognized as reliable observers of children's classroom-based behaviors and skills (Cabell, Justice, Zucker, & Kilday, 2009), since they are able to use ongoing observations to interpret children's participation across a variety of classroom activities (Meisels, Liaw, Dorfman, & Nelson, 1995).…”
