中文摘要：

以391名初一（青少年早期）和高一（青少年中期）学生为被试，探讨了父母支持、友谊支持对孤独感和抑郁的影响模式。结果表明：（1）友谊支持是预测孤独感的更好指标，父母支持是预测抑郁的更好指标；（2）父母支持和友谊支持仅对早期青少年孤独感和抑郁的影响存在显著交互作用，但作用模式不同：父母支持可增强高友谊支持对降低青少年孤独感的作用（增强模式）而友谊支持可补偿低父母支持对降低青少年孤独感的作用（补偿模式）；两种支持系统可相互增强对方对降低青少年抑郁水平的效应（相互增强模式）。（3）与青少年早期不同，青少年中期父母支持和友谊支持两个系统以“独立模式”而非“交互模式”影响青少年的情绪适应。结果提示，家庭和同伴系统对青少年情绪适应的影响可能遵循多种模式，但分别适用于不同适应问题和发展阶段。

英文摘要：

Teenagers＇ relationships with parents and friends undergo many changes during their adolescence. Friendship becomes increasingly important. However, researchers have found that support and warmth from parents still play an important role in fostering healthy socioemotional development for adolescents. Although lots of studies have explored the main effect of parental and friendship support on adolescent adjustments, few have examined the interaction between the two. It should be noted that at least three relationship patterns have been discovered according to existing research： an enhancement pattern, a compensation pattern and an independence pattern. But no consistent conclusion about these interaction patterns has been achieved, which is probably due to different emotional problems, ages and genders in different studies. So this study adopted the Chinese modified versions of the Network of Relationships Inventory, Friendship Quality Questionnaire, Loneliness Scale, and Children＇s Depression Inventory, and specially focused on the interaction patterns between parental support and friendship support on adolescent loneliness and depression and their applicability to different stages and genders with a sample of 391 Chinese adolescents （211 boys and 180 girls） from grade 7 （early adolescence） and 10 （middle adolescence）. The main findings were as follows. （1） On one hand, middle adolescents perceived significantly lower parental support and friendship quality than early adolescents did, but no significant difference was found in loneliness and depression. On the other hand, girls perceived obviously higher friendship support than boys did, and no other significant difference was observed between genders. （2） Friendship support was the better predictor for adolescent loneliness, whereas parental support was the better predictor for adolescent depression. （3） During early adolescence, parental support and friendship support had significant interactions in loneliness and depression whi
