The HEXACO (Honest-Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness) six-factor model of personality structure has been in use for over twenty years and offers a convincing alternative to the five-factor model.

This collection of contributions from around the world demonstrates that research into the model is very much alive. Beginning with a historical overview of the early lexical studies of personality structure exploring how past adjective selection has impacted on personality theory, the volume also presents applications of the model and new approaches to measurement, including an extended twin family study examining genetic and environmental variance and a look at the use of behavior cues in a gamified online environment. The volume also presents what is probably the most comprehensive meta-analysis of the psychometric properties of the HEXACO domain scales.

This is essential reading for all researchers and clinicians interested in personality structure.
