Background: The main research objective was to translate and evaluate the Polish version of the As-If-Scale (AIS) as well as to test the measurement invariance of the Polish and the original (German) versions of the tool, and to analyze the differences in histrionic self-presentation style among Poles and Germans. The AIS consists of 8 items for the subjective assessment of the histrionic self-presentation style which involves behaviors such as playing roles, imitating people or even engaging others in performing small role-plays, and is seen as an individual difference phenomenon.
Participants and procedure: The psychometric properties of the Polish version were tested in two samples with a total of 762 participants.
Results: The article presents the factor structure and reliability of the scale. In addition, the AIS was correlated with measures of the Big Five personality traits, pragmatism and gelotophobia to provide initial validation. Measurement invariance was tested using data collected in this study (Polish sample) and existing and previously published data (German sample).
Conclusions: Overall, the results provide support for the reliability of the scale as its properties are similar to those of the German version. The findings also allow one to make broader cross-cultural comparisons of the histrionic self-presentation style, which includes various types of behavior and is often associated with humor.
Keywords: Humor; cross-national comparison; histrionic self-presentation style.
