人际扩张量表：自我扩张的单项目测量

Interpersonal Expansion Scale: A Single Item Measure of Self-Expansion

摘要: 自我扩张模型认为人们有着寻求扩张自身潜能，也就是自我扩张的动机，而实现这种动机的一种重要方式就是将他人纳入自我，并且将对方的资源、观点和身份体验成自己的。将他人纳入自我和自我扩张分别可以使用将他人纳入自我量表和自我扩张问卷进行测量，但是自我扩张问卷相对将他人纳入自我量表而言存在效率不高、灵活性较差的缺点。为了解决这一不足，我们编制了对自我扩张的单项目图形测量，即人际扩张量表。检验发现该量表具有良好的信效度，且和关系满意度、承诺等关系质量指标存在正相关。结果未发现自我扩张存在伴侣间效应。这些结果可能意味着，尽管自我扩张虽然对关系质量有益，但本质上并不是互惠的过程。人际扩张量表的编制对将来进行自我扩张模型的进一步研究有着积极的意义。

Abstract: The self-expansion model holds that people have the motivation of seeking to expand their self-potential, that is, the motivation of self-expansion. One of the important ways to fulfill this motivation is to include others into themselves, and experience their resources, viewpoints and identities as their own. The inclusion of other in the self and self-expansion can be measured by the Inclusion of Other in the Self Scale and the Self-Expansion Questionnaire respectively. Self-Expansion Questionnaire has the disadvantages of low efficiency and poor flexibility compared with the Inclusion of Other in the Self Scale. To address this shortcoming, we developed a single item graphical measure of self-expansion, the Interpersonal Expansion Scale. The results found that the Interpersonal Expansion Scale had good reliability and validity. The score of the Interpersonal Expansion Scale was also found to be positively correlated with relationship quality index, such as relationship satisfaction and commitment. No dyadic effects of self-expansion were found. These results may indict that while self-expansion is beneficial for actor’s relationship quality, it is not inherently a mutually beneficial process. The development of the Interpersonal Expansion Scale may have positive significance for the further study of self-expansion model in the future.
