Doherty, R. W. (1997). The Emotional contagion scale: A measure of individual differences. Journal of Nonverbal Behavior, 21, pp. 131-154.
Primary use / Purpose:
Emotional contagion describes a certain sensitivity to the emotions of others, and induces the individual to unintentionally 'catch' those emotions from mere exposure to others' behaviour. The EC Scale provides a measure of emotional arousal, and the congruence of emotional stimulus and response. It represents an ideal measure to employ when the researcher attempts to use emotional expression as the independent variable.
Psychometric evaluation of the EC Scale is discussed in Doherty (1997).
