Happiness as stable extraversion: A cross-cultural examination of the reliability and validity of the Oxford Happiness Inventory among students in the U.K., U.S.A., Australia, and Canada

The Oxford Happiness Inventory and the short form Revised Eysenck Personality Questionnaire were completed by four samples of students: 378 in the U.K., 212 in the U.S.A., 255 in Australia, and 231 in Canada. The findings confirm the internal reliability of the Oxford Happiness Inventory and support the view that happiness could be called stable extraversion.
