A three-item unipolar scale measuring the subjective experience of psychological discomfort — a state of unease, discomfort, and feeling bothered — arising from inconsistency between beliefs, attitudes, or between attitudes and behaviour. Originally developed to operationalise cognitive dissonance as a felt psychological state, the scale has been applied in consumer research to examine dissonance following attitude-inconsistent product choices and exposure to counterstereotypic brand personalities.
