以424名农村儿童为被试, 基于留守儿童和非留守儿童之间的比较, 在同伴关系的背景下探讨了亲子亲合与个体逆境信念对儿童攻击、学业违纪与孤独感的作用。结果表明：（1）同伴拒绝能显著增加儿童的攻击、学业违纪与孤独感, 同伴接纳则显著降低儿童的学业违纪与孤独感, 亲子亲合、积极的逆境信念能够显著降低儿童的孤独感; （2）亲子亲合对同伴拒绝与儿童攻击、学业违纪之间关系的调节效应在双亲外出儿童与非留守儿童群体中存在差异：高亲合条件下, 同伴拒绝与非留守儿童的攻击、学业违纪之间存在显著关联, 但是在双亲外出儿童中, 这些关联不再显著; （3）亲子亲合能够调节同伴接纳与儿童孤独感之间的关系：在低亲合条件下, 同伴接纳能够显著降低儿童的孤独感, 但是二者在高亲合条件下不再存在关联。结果提示, 农村留守儿童与父母间的紧密情感联结对于促进其心理适应具有保护作用, 同伴接纳对儿童的亲情缺失具有补偿作用。

英文摘要：

The widening gap in societal and economic development between urban and rural communities and the relaxation of migration restrictions in China since the 1980s have led large numbers of rural laborers to leave their countryside homes in search of better job opportunities in urban areas. As a result of this wave of migration, millions of children were left behind by their migrant parent in rural communities, in the care of the nonmigrant parent, the children’s grandparents or other relatives, even some are left to care for themselves. Long-term and long-distance family separation and lack of face-to-face communications characterize the interactions between migrant parent（s） and their left-behind offspring, and this relative absence of parental affection puts left-behind children at a disadvantage compared with children from nonmigrant families. Although left-behind children were reported to have a higher probability of risk for maladjustment than their peers from nonmigrant families, literatures suggest that there are considerable variations in the adaptations of left-behind children; while some children are at a high risk for delays in adaptive functioning, some do not experience adaptive problems, and still some even show positive development. A key issue with important preventive and theoretical implications in the study of left-behind children involves the identification of potentially protective processes that support positive adaptation in children from migrant families. The present study was designed to examine the moderate effects of parental cohesion and children’s cultural beliefs about adversity on the relationship between peer rejection/acceptance and adaptive functioning by comparing left-behind children with children from nonmigrant families. A total of 424 rural children were recruited from a rural area in Henan province of China, including 76 children from two-parent-migrant families, 133 children from father-migrant families, and 215 children from nonmigrant families. Peer rejection and ac
