The sample comprised 547 Tibetan high school students aged 15–18 years (female = 69.5%, mean age = 16.67 years, SD = 0.95) from the Gannan Tibetan Autonomous Prefecture, China. They completed questionnaires surveys on NCLP, social adaptation, prosocial tendency, and language communication strategies. The mediation analysis results indicated that NCLP significantly predicted social adaptation. Prosocial tendency and language communication strategies independently and significantly mediated the relationship between NCLP and social adaptation. Prosocial tendency and language communication strategies played a chain-mediating role between NCLP and social adaptation. Moreover, no significant gender differences were found in this mediating mechanism. These findings align with Language Socialization Theory, indicating that NCLP shows significant associations with the development of prosocial tendencies and the selection of language communication strategies, which in turn are linked to social adaptation.
