Promoting prosocial behavior among adolescents protects them against problematic outcomes and ensures their positive development. This study aimed to examine (1) the association between adolescents’ representation of acceptance-rejection from multiple attachment figures (father, mother, best friend, and teacher) and prosocial behavior toward multiple targets (stranger, friends, and family) and (2) the mediating role of sense of authenticity in these relationships. The sample comprised 784 adolescents (56% boys), aged 12–15 years (M = 13.98 years, SD = .83). Data were collected online by a research company using six self-report measures. The structural equation model suggested that paternal acceptance-rejection was significantly directly associated with prosocial acts toward three targets and maternal acceptance-rejection was indirectly associated with prosocial acts toward a stranger. Moreover, best friend and teacher acceptance-rejection was related to prosocial acts toward family and friends, and friends respectively. Sense of authenticity mediated the association between maternal and best friend acceptance-rejection and prosocial behavior toward strangers. The findings reveal that the benefits of providing acceptance or love in a relationship are reciprocal and offer personal benefits and increased welfare of others.

促进青少年的亲社会行为可以保护他们免受问题结果的影响，并确保他们的积极发展。本研究旨在检查 (1) 青少年从多个依恋对象 (父亲、母亲、最好的朋友和老师) 的接受-拒绝表现与对多个目标 (陌生人、朋友和家人) 的亲社会行为之间的关联和 (2 ）真实感在这些关系中的中介作用。样本包括 784 名青少年（56% 男孩），年龄在 12-15 岁之间（M  = 13.98 岁，SD = .83）。一家研究公司使用六种自我报告措施在线收集数据。结构方程模型表明，父亲接受-拒绝与对三个目标的亲社会行为显着直接相关，而母亲接受-拒绝与对陌生人的亲社会行为间接相关。此外，最好的朋友和老师的接受-拒绝分别与对家人和朋友以及朋友的亲社会行为有关。真实感介导了母亲和最好的朋友接受-拒绝与对陌生人的亲社会行为之间的关联。研究结果表明，在关系中提供接纳或爱的好处是互惠的，可以提供个人利益和增加他人的福利。
