The participants completed the PSS-10-C (Table 1) . The PSS-10-C is made up of 10 items, each of which offers five response options: never, almost never, occasionally, almost always and always. Items 1, 2, 3, 6, 9 and 10 are scored directly from 0 to 4 and items 4, 5, 7 and 8, conversely, from 4 to 0. The PSS-10 was considered due to the acceptable internal consistency shown in other Colombian studies, with a Cronbach's alpha between 0.65 and 0.86. 6.7 Internal consistency was calculated with Cronbach's alpha coefficient 8 and the EFA, in which it was determined whether the items grouped a latent factor (Bartlett's Test of Sphericity and Kaiser-Meyer-Olkin [KMO] sample adequacy test) and the number of factors (with eigenvalue and explained variance). The analysis was performed using IBM-SPSS version 23 9

The PSS-10-C showed  = 0.86. In the EFA, the Bartlett test showed  2 = 1,399.35; degrees of freedom = 54; p <0.001 and KMO = 0.82. A single factor was identified, with an eigenvalue of 4.42, which explained 44.2% of the total variance. The observed scores were between 0 and 36 (16.5 ± 7.3); 58 people scored 25 or more.

These findings are encouraging, but the EFA data are somewhat different from those expected under ideal conditions: that the identified factor explains at least 50%. 10 Some additional adjustments may need to be made to the wording of this version 11 . However, it is proposed to use the cutoff point of ≥25 for COVID-19-related perceived high stress in the possible studies that are carried out at this juncture, and to have a similar measure of such stress in the Colombian population. In addition, it is important to test the performance of the PSS-10-C in other Colombian samples, given the variations that can be observed according to the characteristics of the population 12 , and to carry out a confirmatory factor analysis when an EFA with better indicators is available.
