Resumen
HERNANDEZ-POSADAS, Alejandrina et al. Psychometric properties of the Mexican version of the Intolerance of Uncertainty Scale: The IUS-12M. Interacciones [online]. 2023, vol.9, pp.e358-. Epub 23-Mar-2023. ISSN 2411-5940. http://dx.doi.org/10.24016/2023.v9.358.
Background:
The Intolerance of Uncertainty Scale short version (IUS-12) has proven to be a robust self-report measure to assess intolerance of uncertainty. While previous psychometric analyses of the IUS-12 have established a stable two-factor structure corresponding to the prospective and inhibitory factors of intolerance of uncertainty, recent studies suggest that the bifactor model may better explain its factor structure.
Objective:
The aim of the current study was to culturally adapt and validate the IUS-12 in a Mexican population.
Method:
The aim of the current study was to culturally adapt and validate the IUS-12 in a Mexican population.
Result:
Confirmatory factor analyses supported a bifactor model and a good internal consistency. Invariance testing indicated partial invariance across women and men. Convergent validity tests showed that the IUS-12 was related to measures of worry, as well as depression and anxiety.
Conclusion:
These findings provide evidence for the reliability and validity of the adapted version of the IUS-12 in Mexico.
