QUEZADA-BERUMEN, Lucía  and  GONZALEZ-RAMIREZ, Mónica Teresa. Psychometric properties of the post-traumatic growth inventory in mexican population. Acción psicol. [online]. 2020, vol.17, n.1, pp.13-28.  Epub July 25, 2022. ISSN 2255-1271.  https://dx.doi.org/10.5944/ap.17.1.25736.

Although the post-traumatic growth inventory (PTGI) is a widely used instrument to assess positive changes after trauma, its factor structure has not been consistent in the validations made in Spanish. Currently, there is no evidence of the study of its psychometric properties in Mexican population, so the purpose of this study was to contrast the factor structure of the PTGI and describe the average profile of post-traumatic growth in a Mexican sample. The sample consisted in 446 people aged 18 to 77 years, victims of different traumatic events. The results showed a unifactorial solution, which showed adequate goodness of fit and excellent reliability (α = .94). A moderate change in growth was identified, being equivalent according to sex. The PTGI-M is considered an instrument with good psychometric properties to evaluate growth after a traumatic event in Mexican population.
