Theory of Mind (ToM) or the ability to understand mental states in self and others to explain behavior continues to develop in adolescence and connects to social experiences. Research shows during adolescence, ToM may influence one's ability to evaluate and judge one's self-worth and their social interactions. However, few studies examine the associations among self-knowledge, ToM, and social experiences. This study explored individual differences and associations among 146 Canadian adolescents' ToM, self-knowledge, and loneliness (86 females; Mage = 13.2 years). Self-report questionnaires and semi-structured interviews measured ToM, self-knowledge, and perceptions of friendship quality, social preferences, and loneliness. Results showed higher levels of ToM were related to lower ratings of self-perceived physical appearance, global self-worth, and loneliness. Compared to boys, girls with higher levels of ToM reported a more comprehensive understanding of self-distinctiveness and agency, although they felt less lonely. Implications for developmental social cognitive theory and mental health education are discussed.

新兴青少年的心智，自我知识和孤独感感知理论。

心智理论（ToM）或了解自我和他人心理状态以解释行为的能力在青少年时期不断发展，并与社会经验联系在一起。研究表明，在青春期，ToM可能会影响一个人评估和判断其自我价值的能力以及他们与社会的互动。但是，很少有研究检验自我知识，ToM和社会经验之间的关联。这项研究探讨了146名加拿大青少年的ToM，自我知识和孤独感（86名女性；法师= 13.2岁）之间的个体差异和关联。自我报告调查表和半结构化访谈测量了ToM，自我知识以及对友谊质量，社会偏好和孤独感的看法。结果表明，较高的ToM含量与较低的自我感觉到的物理外观评级有关，全球的自我价值和孤独感。与男孩相比，ToM含量较高的女孩尽管对孤独感和孤独感的感觉较差，但对自我区分和代理的理解更为全面。讨论了发展性社会认知理论和心理健康教育的意义。
