Background: The Emotional Contagion Scale (ECS) is a self-report scale used to measure individual differences in susceptibility to converge towards the emotions expressed by others. The main aim of the present paper was to examine the psychometric properties of the Greek translation of the scale.

Theories regarding susceptibility to emotional contagion, which address the ease of “catching” the emotions expressed by others, have recently received growing interest in the field of social psychology and health. Despite the theoretical and empirical importance, reliable and valid instruments to assess emotional contagion in men and women from cultures outside the English-speaking world are not well developed. The present study examines the psychometric properties and factor structure of the Greek adaptation of the Emotional Contagion Scale (ECS), and is a first attempt to test its measurement invariance across gender and culture groups (Greece and Sweden). Confirmatory factor analysis (CFA) of competing models supports a five-factor model that includes the five basic emotions of anger, fear, sadness, happiness, and love. Using multiple-group CFA and a sequence of nested tests, configural invariance and partial metric and partial scalar invariance across gender and culture groups of the five-factor model were demonstrated. The results show that meaningful comparisons of ECS can be made across men and women from different cultures and support the hypothesis that susceptibility to emotional contagion operates at a differential emotions level.
