探讨9—15岁流动儿童自我概念的发展及其与心理健康的关系。选取北京市4所打工子弟学校9—15岁流动儿童644名，9—15岁城市普通儿童441名。采用Song—Hattie自我概念量表和心理健康量表（青少年版）分别评估自我概念和心理健康状况。结果发现：（1）流动儿童自我概念自9岁至15岁总体上均呈现下降趋势；（2）流动儿童的自我概念水平显著低于同龄城市普通儿童，但总体发展趋势与普通儿童相似；（3）流动儿童自我概念与心理健康之间存在正相关关系．自我概念各因子对心理健康有很好的预测作用。

To explore the development of self-concept of migrant children aged from 9- to 15-years old and its rela-tionship with mental health. 644 migrant children from 4 schools and 441 city normal children randomly selected from Beijing area were invited to participate in the investigation. They were assessed with Song-Hattie self-concept inventory and mental health inventory for children to evaluate their self-concept and mental health. In general, the self-concept of migrant children tended to descend from 9 years old to 15 years old, and the self-concept of migrant children was lower than that of normal children. There were significant positive correlations between self-concept and mental health of migrant children. The findings of this study suggest that the self-concept of migrant children should be greatly concerned in the practical education.
