The Internalized Group Threat Scale is an instrument that measures the prejudice perceived by Latin American immigrants from the threat theory. The objective of the research was to evaluate the psychometric properties of this scale in Latin American immigrants living in Chile. Through a non-experimental methodology, which had a non-probabilistic sample, two cross-sectional studies were carried out, in which a total of 722 immigrants participated. The findings of the first study, based on an exploratory factor analysis, show a unifactorial structure of the Internalized Group Threat Scale and an omega coefficient of. 87. On the other hand, the results of the second study, based on a confirmatory factor analysis, corroborate the factorial structure of the scale for a 7-item model with adequate fit indices and factor loads greater than. 50. Likewise, statistically significant, inverse and moderate correlations were found with the Self-Esteem Scale and the Multigroup Ethnic Identity Scale. Finally, an omega coefficient of. 89 was found. It is concluded that the Internalized Group Threat Scale has adequate psychometric properties for its use with Latin American immigrants residing in Chile.
