Abstract:
Dual identity has an assumption that subordinate group identity (e.g., ethnic and tribe identity) and
superordinate group identity (e.g., national identity) can be simultaneously activated. The dual identity
concept is important to examine in Indonesia as the country of thousands of tribes. As an initial step, we
should adapt and evaluate a dual identity scale so that later it will become a catalyst for future study on the
exploration of the association of dual identity and other factors. This study aims to adapt and evaluate the
dual identity scale on the Indonesian sample. We tested the measurement through two collecting data, with
775 of total participants (data 1= 338 participants and data 2= 473 participants). The data were analyzed
using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We found that the dual
identity scale had a good fit model and had satisfactory validity and reliability. The validity and reliability
of data 2 are better than data 1. In the data 2, each item of items used ‘tribe’ as a form of subordinate identity
to replace ‘ethnic’ in the measurement of the data 1. In data 1, this scale had a significant correlation with
ethnic and national identity. The result of EFA and CFA proved that the scale is unidimensional (having one
factor) and robust to use in the Indonesian sample. The study also found that the use of ‘tribe’ can explain
subordinate identity better than "ethnic" on the scale. This study contributes to a practical implication for using the dual identity scale in Indonesia.
