Previous research conducted by the same authors found that personal attributes (benevolence, integrity, competence) and the relational attributes (closeness, support, and reciprocity) influence trust and trustworthiness. This paper aimed to test the proposed trust model on a new dataset while also testing for gender and regional differences. This research involved a collaboration between Universitas Gadjah Mada as a representative from Yogyakarta and Universitas Negeri Makassar as a representative from Makassar. There were 420 students that participated in this study; 157 (37.4%) men and 263 (62.6%) women. Regression analyses indicated that 42% of trust was formed by personal and relational attributes. Contrary to expectations, there were no differences in trust ( p> 0.05) between females and males. However, there was a significant difference in trustworthiness (p<0.01) between women and men. Furthermore, this paper also found that there were no differences in trust between the regions; Yogyakarta and Makassar (p>0.05). This study provides an understanding on the importance of trust and trustworthiness in efforts to maintain pluralism, as a form of citizenship identity.

Other definitions of trust highlight the aspect of willing to be vulnerable (easily attacked or hurt) based on people’s positive expectations toward their relationships with other people (Mayer, Davis, & Schoorman, 1995; Rousseau, Sitkin, Burt, & Camerer, 1998). Despite this, trust cannot grow without considering the other person’s trustworthiness (Kim et al., 2009). Trustworthiness is an antecedent of trust or in other words, trust grows with the presence of trustworthiness (Sekhon, Ennew, Kharouf, & Devlin, 2014). Trustworthiness can take the form of values or individual characteristics which are expressed in the behaviors that
