Resumen:
Introduction: The Perceived Stress Scale-4 (PSS-4) is an ultra-brief
self-report measure to assess psychological stress. This study evaluated
the psychometric properties of the PSS-4 in Colombia. Method: A total of
1,911 adult participants with a university education completed the
PSS-4. The characteristics of the items and the subscales were explored.
The dimensionality was assessed using principal component analysis and
confirmatory factor analysis (CFA), incorporating an examination of
invariance (configural, metric, scalar, and strict) across
socio-demographic characteristics. Construct validity (convergent and
discriminant), reliability indices, know-groups, and predictive validity
were also computed. Results: CFA showed that the one-factor model
(psychological stress) with method effects (correlated error terms on
the negative-phrased items) was the most appropriate according to fit
indices and parsimony considerations, being invariant across gender and
age, but not across income level and work status. Internal consistency
was adequate for the PSS-4. Significant positive correlations of the
PSS-4 were identified with depression and anxiety, as well as
significant negative correlations were identified with post-traumatic
growth and resilience. The PSS-4 showed adequate capacity to predict
potential depressive and anxiety symptoms, as well as protective factors
such as resilience and post-traumatic growth. Higher scores on the PSS-4
were observed among young people, as well as among people with lower
incomes and those who are unemployed. Conclusions: These findings
suggest that the PSS-4 can be a reliable and valid tool for assessing
psychological stress in Colombians with a university education.
