The goal of this research was to examine the measurement invariance of the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) across two European nations. Participants were Italian and German undergraduate students. First, confirmatory factor analysis was used to test for the two-factor structure of the ERQ; subsequently, measurement invariance was analysed. The results showed acceptable fit indices for the German and Italian sample; however, results with regard to the Italian sample showed lower fit indices than results regarding the German one. Measurement invariance of the ERQ across Italy and Germany was confirmed. Despite the fact that we assumed measurement invariance of the ERQ, future research is needed to deal with the lower fit regarding the Italian version.

The topic of my PhD project is sample-size reduction by order constraints. Many researchers are familiar with the power gain in the context of the one-sided t-test.
