We aimed to evaluate whether an ultra-short version of the Posttraumatic Growth Inventory (PTGI) has adequate psychometric properties, with a Colombian sample (N = 931) vulnerable to SaRS-CoV-2 infection. Results indicated that adequate indicators of goodness-of-fit, convergent validity, internal consistency, and factorial invariance. Therefore, this instrument is recommended for the screening of posttraumatic growth associated with the COVID-19 pandemic that may be present in the Colombian population.
