Abstract

Relational aggression is one form of violence that can occur in interpersonal relationships. Relational aggression has various construct variations and measurement tools. Recently, a new measurement tool for relational aggression called the Relational Aggression Scale (RAS) has been developed, which can be used to measure the construct of relational aggression directly, indirectly, proactively, and reactively. This study aims to evaluate the psychometric properties of the RAS in an Indonesian sample. Participants in the study were 712 individuals aged 18-25 years (M = 20.987, SD = 1.552) residing in Surabaya. The sample was collected using convenience sampling. The evaluation of the psychometric properties of the Indonesian version of the RAS included content validity, item accuracy, factor structure, and convergent validity. Aiken V calculation was used to evaluate the content accuracy of the items, and the infit and outfit estimates of the Rasch model were used to evaluate the accuracy of the items on the construct of direct, indirect, proactive, and reactive relational aggression. Factor structure testing was done using confirmatory factor analysis, and convergent validity testing was done by correlating the Indonesian version of the RAS with other relational aggression measurements tools, such as the relational aggression subscale of the Self-Report of Aggression and Social Behavior Measure and the Peer Conflict Scale. The study found that not all items of the Indonesian version of the RAS have satisfactory item quality based on Aiken V calculation and infit and outfit estimates of the Rasch model. However, the Indonesian version of the RAS has a satisfactory factor structure and convergent validity. Although the Indonesian version of the RAS is not perfect in terms of item quality, the Indonesian version of the RAS can be used to measure relational aggression in the Indonesian sample.
