Relationships between happiness and personality

This study investigated relationships between measures of happiness and personality, using multiple regression and a range of personality measures. Three happiness measures, the Oxford Happiness Inventory, the Personal State Questionnaire (version 5), and the Life Orientation Test produced a multiple R of 0.381 with Psychoticism as the dependent variable. Multiple R values around 0.65 were obtained when the happiness measures were predicted from personality variables. Extraversion and Neuroticism were the main predictors as has been previously found.
