Primary use / Purpose: 

The Berkeley Expressivity Questionnaire assesses three facets of emotional expressivity: negative expressivity, positive expressivity, and impulse strength.

Background: 

Emotions help us respond adaptively to environmental challenges and opportunities. Unlike other biologically based response tendencies, such as reflexes, however, emotions only incline us to act in certain ways; they do not compel us to do so. This means that we may deny expression to some emotional impulses while freely expressing others. Striking individual differences in ex-pressivity suggest that people differ in their response tendencies and in how they express these impulses as they arise. The Berkeley Expressivity Questionnaire assesses three different facets of emotional expressivity: negative expressivity, positive expressivity, and impulse strength. 

Psychometrics: 

In the most recent study, the alphas were .86 for the total BEQ, and .70, .70, and .80 for the three subscales Negative Expressivity, Positive Expressivity, and Impulse Strength, respectively. Exploratory factor analysis revealed that the 16 items in the BEQ were all positively intercorrelated, with a mean interitem correlation of .27. To test whether the BEQ items would again form a General Expressivity factor with three facets, we subjected the interitem correlation matrix to a principal-components analysis. The first unrotated factor accounted for 33% of the total variance, and all 16 items loaded positively, with a mean loading of .57. The two items with the highest loadings (.75 and .73,  respectively) were "I am an emotionally expressive  person," and "What I'm feeling is written all over my face."
