Predicting donation behaviour with the Supernumerary Personality Inventory

The present study aimed to broaden the investigation of personality traits and donation behaviour beyond the Five-Factor Model (FFM) framework. A sample of 506 participants completed the Supernumerary Personality Inventory (Paunonen, 2002), reported both their frequency of charitable giving and, given the option to donate potential lottery winnings to a charitable cause, the amount that they would donate. Religiosity was moderately positively correlated with charitable frequency, while integrity was weakly positively correlated with donation amount. Manipulativeness and egotism were weakly negatively correlated with donation amount. Overall, the results show limited evidence for the relevance of Supernumerary Personality Inventory personality traits in prosocial behaviour. Suggestions for future research are discussed.
