Prosocial behavior is conducive to social harmony and personal development. Although some studies have shown that perceived social support can enhance prosocial behavior, the specific mechanisms are not clear. This study establishes a serial mediation model to explore the effects of perceived social support on prosocial behavior and the mediating roles of sense of gain and gratitude.
A total of 341 college students aged of 18 to 35(M = 21.52, SD = 2.28, 59.53% female) were surveyed using the perceived social support scale, the sense of gain questionnaire, the gratitude questionnaire, and the prosocial tendency scale.
The results revealed significant positive correlations among perceived social support, sense of gain, gratitude, and prosocial behavior. Furthermore, gratitude plays a mediating role between perceived social support and prosocial behavior, and the sense of gain and gratitude act as a chain of mediating roles between perceived social support and prosocial behavior.
The results indicate that enhancing individuals' perceived social support and increasing their sense of gain and gratitude may be an effective way to promote their prosocial behaviors. However, the cross-sectional design and convenience sampling limit the ability to draw causal and generalizable conclusions.
亲社会行为有利于社会和谐与个人发展。尽管一些研究表明，感知到的社会支持能够增强亲社会行为，但其具体机制尚不清楚。本研究建立了一个系列中介模型，以探讨感知到的社会支持对亲社会行为的影响以及收获感和感恩的中介作用。
采用感知社会支持量表、收获感问卷、感恩问卷和亲社会倾向量表，对341名年龄在18至35岁之间的大学生（M = 21.52，SD = 2.28，女性占59.53%）进行了调查。
结果显示，感知到的社会支持、收获感、感恩和亲社会行为之间存在显著的正相关。此外，感恩在感知到的社会支持和亲社会行为之间起中介作用，收获感和感恩在感知到的社会支持和亲社会行为之间起链式中介作用。
结果表明，增强个体对社会支持的感知以及提高他们的收获感和感恩之情，可能是促进其亲社会行为的有效途径。然而，横断面设计和便利抽样限制了得出因果关系和可推广结论的能力。
