This research examined the structure and correlates of the Humor Styles Questionnaire (HSQ) in Lebanese university students. Four humour factors were found, as in the original Canadian samples: Affiliative, Self-Enhancing, Aggressive, and Self-Defeating humour. Scale reliabilities were generally acceptable, and inter-correlations among the scales were low. Lebanese participants scored lower than Canadians on Affiliative and Self-Enhancing humour and lower than Belgians on Affiliative and Aggressive humour. As in Canadian and Belgian samples, males reported significantly more use of Aggressive and Self-Defeating humour than did females. Humour styles correlated differentially, and generally as predicted, with horizontal and vertical individualism and collectivism, attachment styles, perceived health, and psychological well-being. Overall, the findings support the cross-cultural stability of the HSQ as well as the differential relationship of these humour styles with culture-related personality traits and psychological well-being.
