采用方便抽样法从山东某初中和某高中抽取570名学生做问卷调查, 考察家庭压力源对青少年抑郁体验的影响，特别是冗思作为应对方式的中介作用。路径分析的结果显示：（1）家庭冲突和父母期望均显著正向预测抑郁体验，且家庭冲突的预测作用更强；家庭规范对抑郁体验的预测作用不显著；（2）家庭冲突和父母期望均显著正向预测青少年冗思，家庭规范对冗思的预测作用不显著；（3）冗思显著正向预测抑郁体验；（4）冗思在家庭冲突与抑郁体验之间以及父母期望与抑郁体验之间均起中介作用。总体来看，冗思是家庭压力影响青少年抑郁体验的内部机制之一。

英文摘要：

Adolescence is characteristic of more vulnerability to depressive symptoms as adolescents develop rapidly in various aspects such as physical fitness, cognitive capacity and social roles. On the path to seek autonomy, independence and social identity, adolescents inevitably face various kinds of stressors which induce depressive symptoms when they could not cope with them adequately. Among these stressors, home stressors exist so frequently in adolescents＇ life that might aggravate adolescents＇ depressive symptoms. Although extant research has established the relationship between stressors and adolescents＇ depression, the mediating linkages in between remains to be explored. As a coping strategy, rumination refers to individuals＇ frequent recall of negative events that has happened in the past. The current study hypothesized that three home stressors such as family conflict, parental expectation and family rules are not only directly predict adolescents＇ depressive symptoms, they also indirectly affect depression through the mediating role of rumination. Aiming at testing these hypotheses, 570 students were chosen conveniently as our subjects from one junior high school and one senior high school in Jining, Shandong province, and data was gathered by administering such instruments as Depressive Experience Questionnaire, Ruminative Responses Scale, and Family Stress Questionnaire. By conducting path analyses, results indicated that both family conflict and parental expectation positively and significantly prophesy adolescents＇ depressive symptoms while family rules had no significant effect on depression. Similarly, the former two types of family stressors had positive and significant effect on adolescents＇ rumination while the third type had no obvious effect on depression. And rumination had positive and significant effect on depression. Taken together, rumination mediated the relationship between family stress and adolescents＇ depressive symptoms. Based on the above results, the following conclu
