Group cohesiveness

Group cohesiveness, also called group cohesion, social harmony or social cohesion, is the degree or strength of bonds linking members of a social group to one another and to the group as a whole. Although cohesion is a multi-faceted process, it can be broken down into four main components: social relations, task relations, perceived unity, and emotions. Members of strongly cohesive groups are more inclined to participate readily and to stay with the group.

There are different ways to define group cohesion, depending on how researchers conceptualize this concept. However, most researchers define cohesion to be task commitment and interpersonal attraction to the group.

Cohesion can be more specifically defined as the tendency for a group to be in unity while working towards a goal or to satisfy the emotional needs of its members. This definition includes important aspects of cohesiveness, including its multidimensionality, dynamic nature, instrumental basis, and emotional dimension. Its multidimensionality refers to how cohesion is based on many factors. Its dynamic nature refers to how it gradually changes over time in its strength and form from the time a group is formed to when a group is disbanded. Its instrumental basis refers to how people cohere for some purpose, whether it be for a task or for social reasons. Its emotional dimension refers to how cohesion is pleasing to its group members. This definition can be generalized to most groups characterized by the group definition discussed above. These groups include sports teams, work groups, military units, fraternity groups, and social groups. However, it is important to note that other researchers claim that cohesion cannot be generalized across many groups.

The bonds between group members do not develop spontaneously. They develop from a number of components such as attraction, coordination, sense of belonging and shared emotions. The components can be known as antecedents of cohesion. Moreover, they also define the nature of cohesion. Each component is explained in-depth below.

Festinger and his colleagues in 1950 focused on attraction as a force in comparison to any other forces. In a study, they asked the group members to identify all their good friends and calculated the ratio of ingroup choices to outgroup choices. According to Dion in 2000, the greater the ratio, the greater the cohesiveness of the group. Hogg in 1992 and 2001 noted personal attraction is not a group cohesion even though members of cohesive groups like one another. Group cohesion is similar to a type of group-level attraction which, according to Hogg, is known as social attraction. Social attraction is a liking for other group members based on their status as typical group members. Attraction is a basic ingredient for most groups, however, when interpersonal relations between group members intensify, it can transform a conjoined group into a cohesive one.

In a cohesive group, individuals tend to fuse together to form a whole. Nonmembers who would encounter a group will be convinced that it is a tightly bonded group. Group members would express their sense of belonging to the group by being loyal to the group, identifying with the group and classifying themselves as members. They would also describe their unity by using terms such as family, us, community, team, etc.

It is believed that cohesion is more about the willingness to work together to accomplish a set of goals than the interpersonal relationships between group members. According to Siebold in 2007, task-oriented groups such as flight crews and military squads share a drive to accomplish their goals.

One of the most obvious features of a cohesive group is a shared positive emotion. Emotional cohesion is a multilevel process as emotions can be collective. For example, a group member may experience emotion when he/she learns that the other group member has been mistreated. An emotion is a collective emotion when all the members of a group experience the same emotional reaction. The intensity of such emotions is high when the members strongly identify with their group.
