Abstract: Parent-child communication quality could influence individual’s trust level. Based on a sample of 172 Chinese college freshers, the present study examined the relationship of freshers’ parent-child communication quality and their trust circle through the scale of parent-child communication quality and the questionnaire of “trust circle”. The results indicated that: (1) the quality of father-child communication is worse than that of mother-child, especially the relationship-oriented communication quality. (2) The trust circle size varies with risk level; as the economic risk increases the trust circle becomes smaller, and as the degree of the shared negative information increases the trust circle also becomes smaller. The average trust circle sizes in different domains differ, the size of the trust circle in the economic situation is larger than that in the negative information sharing context. (3) In the economic situation, trust circle sizes of the participants with higher quality in parent-child communication were larger than those with lower quality in parent- child communication.

Key words: parent-child communication, trust circle, risk level.

摘要： 研究以172名大学新生为被试，采用量表法测量其亲子沟通质量和不同情景中的信任圈大小。结果表明：（1）大学新生关系指向的亲子沟通质量高于问题指向的沟通质量，父子沟通在关系指向上的质量低于母子沟通，在问题指向上两者没有显著差异；（2）在借钱和负面信息分享两个情景中大学新生的信任圈大小不同，且随着风险等级的增加，大学新生的信任圈明显缩小；（3）在借钱情景中，亲子沟通质量较高组的大学新生信任圈较大，而亲子沟通质量较差组被试信任圈较小，在负面信息分享情景中，亲子沟通质量不影响信任水平。
