中文摘要：

以560名5、7、10年级学生为被试，检验父母支持、友谊质量与孤独感、抑郁的关系是否符合间接效应模型及其模型适用性问题。结构方程建模及群组分析结果发现：（1）总体上，间接效应模型成立，父母支持既直接影响孤独感和抑郁，也通过影响友谊质量进而影响孤独感和抑郁状况；f2）从具体适应问题看，间接效应模型对于孤独感和抑郁均显著，但更适用于对孤独感的预测；（3）从发展阶段看，间接效应模型仅适用于童年晚期和青少年早期，且更适用于童年晚期；（4）从性别角度看，间接效应模型对两性均显著，但更适用于男生。结果提示，父母支持、友谊质量对孤独感和抑郁的影响均符合间接效应模型，但该模型的适用性可能因具体适应问题、发展阶段和性别而有差异。

英文摘要：

Rubin et al. （2004） indicated that at least three linking ways might exist in the relationships between emotional adjustment and child-parent relationships and friendship quality： an independence model, an interaction model, and an indirect effect model. The indirect effect model, however, has stayed to be a theoretical hypothesis and lacked enough empirical evidence. Furthermore, it is possibly different when applied to different emotional problems （e.g., loneliness vs depression）, developmental stages and genders. Thus, the present study explored the validity and applicability of the indirect effect model. A total of 560 students from grade 5 （late childhood）, grade 7 （early adolescence）, and grade 10 （middle adolescence） were surveyed with questionnaires, including the Chinese versions of Network of Relationships Inventory （Furman ＆ Buhrmester, 1985）, Peer Nomination Questionnaire, the Friendship Quality Questionnaire （Parker ＆ Asher, 1993）, the Loneliness Scale （Asher, Hymel, ＆ Renshaw, 1984））, and the Children＇s Depression Inventory （Kovacs, 1992）. Among them, each of 458 participants had at least one mutual best same-sex friend. At last, the present study conducted correlation analyses, structural equation modeling and its multiple-group analyses mainly on their data using SPSS 13.0 and Amos 7.0. The main findings were as follows： （1） overall, the indirect effect model was found to be significant, parental support negatively affected the participants＇ loneliness and depression both directly and indirectly via friendship quality; （2） in terms of emotional adjustment problems, the indirect effect model was significant for both loneliness and depression, but it was more applicable to predict loneliness; （3） from the aspect of developmental stage, the indirect effect model was applicable to both late childhood and early adolescence, particularly to late childhood; （4） from the gender perspective, the indirect effect model was applicable to bo
