This study examined differences of physical activity levels and social interactions among preschoolers with/without disabilities and those at risk for a developmental delay (DD). Sixty preschoolers (20 in each group) were film during their designated large gross motor time. Their physical activity levels and social interaction were examined using the physical activity level screening. Regarding physical activity levels, the result of a two-way analysis of variance indicated significant main ef-fects for groups, F(2,54)=4.192, P=0.02; preschoolers at risk for a DD were more active than preschoolers without disabilities, P=0.02. For social interaction, a significant main effect for groups, F(2,54)=8.994, P < 0.001 was found; Preschoolers at risk for a DD were more interac-tive than preschoolers with/without disabilities, P=0.001 and P=0.002, respectively. There were no significant gender differences across three groups on physical activity levels and social interactions. Although pre-schoolers at risk for a DD was more active and interactive than the oth-er groups, preschoolers across three groups engaged in light physical activity levels, and had limited social interactions with peers.
