“…In seven studies, the group activities were related to social topics. The group interventions involved structured play and friendship activities for pupils with DD and their TD peers (Frea, Craig-Unkefer, Odom, & Johnson, 1999), interest clubs during lunch or recess in which pupils with ASD and their TD peers were involved in fun activities related to a topic of interest of the pupils with ASD (Koegel, Vernon, Koegel, Koegel, & Paullin, 2012), weekly therapeutic group counselling for the whole class (Shechtman, 1999), or support groups focused on pupils with BD, LD, or ASD involving their TD peers (Frederickson & Turner, 2003;Frederickson, Warren, & Turner, 2005;Kalyva & Avramidis, 2005). In the study of Frederickson and Turner (2003), support groups called "Circle of Friends" were created to discuss strategies weekly to solve the social problems and help pupils with BD.…”
