Psychometric validation of the Polish version of the Emotional Style Questionnaire
In four 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 a second sample and demonstrates that for each of the six subscales construct validity is similar to that of the original scale. Study 4 investigates the test-retest reliability of the scale, and demonstrates very good reliability across an interval of two months. We conclude that the Polish version of ESQ is a psychometrically solid and easily implementable instrument that can be used to measure healthy emotionality and its components in both clinical and research settings.
