M.A. / In this study it is assumed that psychological factors are playing an increasingly important role in the success of rugby teams in a professional era. One such a factor is that of group dynamics and specifically that of group cohesion. In this study, the use of another psychological construct, personality, in the improvement of cohesion is investigated. The personality profiles of the players in a particular team are analysed to determine the possible effects that the personalities of the players could have on the cohesion in the team. In this regard, the Jackson Personality Inventory —Revised is used to plot the personality profiles of all the players. Only scales of the inventory, that are relevant to cohesion, are being used. The relevancy of these particular scales are determined by the literary review of the cohesion construct, which includes the definition and essence of cohesion. Correlation studies would have to determine the true correlation between cohesion and the selected scales of the inventory. General tendencies in the team regarding the profiles and consequent influence on cohesion are discussed as well as the individual profiles of each one of the members of the team. In this regard, the possible influence that a particular player's personality profile could have on the cohesion in the team, is indicated and discussed. It is concluded that the use of personality profiles could be seen as a framework from which coaches and managers of rugbyteams could make use of in order to improve the cohesion in the team.
