Psychometric validation of the Polish version of the Emotional Style Questionnaire

In five studies, we document the validity of the Polish version of the Emotional Style Questionnaire (ESQ)—a 24-item self-report measure that captures how people vary across six dimensions that make up a healthy emotional life. Study 1 provides support for the proposed factorial structure of the Polish version of the scale. Study 2 demonstrates the equivalence of the Polish and English versions of the scale. Study 3 confirms the adequacy of the factorial structure in another sample and shows that construct validity for each of the six subscales is similar to that of the original scale. In Study 4, we demonstrate excellent test-retest reliability of the scale across an interval of two months. In Study 5 we investigate measurement invariance across the Polish and American samples and demonstrate that Poles are characterized by lower scores on healthy emotionality and its dimensions than Americans. We conclude that the Polish version of ESQ is a psychometrically valid and easily implementable measurement tool that can be applied in clinical and research settings to measure healthy emotionality and its components.
