In the study of human motivations, self-interest is often seen as a determining factor and opposed to other-interest. Recently a new conceptualization has been proposed in which both interests can occur at the same time. In order to measure these constructs, the Self-and Other-Interest Inventory (SOII; Gerbasi & Prentice, 2013) was created, which has one version for adults and one for students. Due to the absence of similar measurement instruments in Spain, the aim of this work is to adapt the SOII to Spanish university students. Several studies were conducted. First, the construct was analyzed through rational-analytical procedures. Second, the items were translated following an iterative forward-translation design. Finally, evidence of validity was obtained through analytical procedures. Specifically, two pilot studies were carried out in which two independent samples of Spanish students participated (N1 = 119; N2 = 165). In both studies descriptive analyzes of the items were performed, reliability was estimated and the factor structure of the SOII was explored from an exploratory factor analysis. The results showed adequate reliability and a two-factor solution consistent with the original.

学术环境中自我和其他利益清单的西班牙改编

在对人类动机的研究中，自利通常被视为决定性因素，与其他利益相反。最近提出了一种新的概念化，其中两种兴趣可以同时发生。为了衡量这些结构，我们创建了自我和其他利益量表 (SOII; Gerbasi & Prentice, 2013)，其中有一个针对成人的版本，一个针对学生的版本。由于西班牙没有类似的测量仪器，这项工作的目的是使 SOII 适应西班牙大学生。进行了几项研究。首先，通过理性分析程序对结构进行分析。其次，这些项目是按照迭代正向翻译设计进行翻译的。最后，通过分析程序获得了有效性的证据。具体来说，ñ1 = 119;ñ2 = 165)。在这两项研究中，都对项目进行了描述性分析，估计了可靠性，并从探索性因素分析中探索了 SOII 的因素结构。结果显示了足够的可靠性和与原始结果一致的双因素解决方案。
