This study explores changes in children's social skills after a cognitive-social skills model intervention. The intervention was conducted over a period of 12 weeks within a regular preschool setting. Sixteen children including four considered to have low social skills participated in the study. Data analysis revealed that the four children with low social skills demonstrated changes in social skills through positive play behaviours such as asking positive questions, offering suggestions, initiating play episodes, and sharing play materials, although they had limited ability to maintain play episodes.
