In a growing context of multiculturalism, prosocial behavior is important to build effective social exchange and service orientation among university students. The present study investigates prosocial behavior from a psychometric approach, to obtain evidence of the internal structure of the prosocial behavior scale (PS), in 737 young people enrolled at universities in Argentina (207), Spain (310), and Peru (220). First, the clarity of the items was explored in the three countries; second, possible irrelevant patterns of response, such as the careless and extreme responses, were evaluated; third, the non-parametric Mokken methodology was applied to identify the basic properties of the scale score; fourth, the structural equation modeling (SEM) methodology was used to identify the properties of the internal structure (dimensionality, tau-equivalence) of the latent construct; fifth, the measurement invariance according to sex (intra-equivalence) and country (inter-equivalence) was examined with the SEM methodology and other complementary strategies. Finally, reliability and internal consistency were evaluated both at score level and at item level. Implications for use of the PS instrument are discussed.
在多元文化主义不断发展的背景下，亲社会行为对于在大学生中建立有效的社会交流和服务导向至关重要。本研究从心理测量学的角度对亲社会行为进行调查，以获取亲社会行为量表（PS）内部结构的证据，该研究涉及737名就读于阿根廷（207人）、西班牙（310人）和秘鲁（220人）大学的年轻人。首先，在三个国家探索了项目的清晰度；其次，评估了可能的无关反应模式，如粗心和极端反应；第三，应用非参数莫肯方法来确定量表分数的基本属性；第四，使用结构方程建模（SEM）方法来确定潜在结构的内部结构属性（维度、tau等价性）；第五，使用SEM方法和其他补充策略检验了性别（内部等价性）和国家（外部等价性）的测量不变性。最后，在分数水平和项目水平上评估了信度和内部一致性。讨论了PS工具的使用意义。
