“…They defined cohesion as the extent to which the individuals have formed "close friendships with others in their immediate work unit and their personal attraction to members of the group". In contrast, the definition that was proposed by Carron, Widmeyer, and Brawley (1985), refined by Carron et al (1998), and invoked by many other researchers (e.g., Ahronson, & Cameron, 2007;Hambley, O'Neill, & Kline, 2007;Heuze, Bosselut, & Thomas, 2007;Senecal, Loughead, & Bloom, 2008;Spink, Wilson, &Odnokon, 2009;Tekleab, Quigley, & Tesluk, 2009), assumes that cohesive groups are united to increase the "satisfaction of member affective needs", pursue "instrumental objectives", or both (for a similar perspective, see Cota, Evans, Longman, Dion, & Kilik, 1995). That is, these researchers assume that both social cohesion and task cohesion should be measured.…”
