Most research within sports has been completed on those who participate in a team, although as mentioned previously a team could be as little as 2 members. In a golfing situation or in individual sports cohesion still does occur, but usually between opponents, such sports as regarded as co-active. Whereas team sports are referred to as interactive sports. Studies have been conducted on such groups, to see if differences exist to try and summarise a cohesion performance effect. (Kozub and Button, 2000; Grieve et al., 2000; Williams and Widmeyer, 1991). Kozub and Button (2000) studied both rugby and swimming teams and summarised that cohesion is more important for interacting teams in a cohesion-performance situation and furthermore the team attractiveness may be increased by success. Research has earlier predicted a negative cohesion-performance for coacting sports (Brawley, Carron and Widmeyer, 1987). Although Williams and Widmeyer (1991) hypothesised against previous beliefs and their results showed a positive relationship between cohesion and performance. On the opposite stance of interacting team sports Grieve et al., (2000) examined basketball teams and the effect of cohesion and in contrast to previous evidence (Mullen and Cooper, 1994) the authors found a negible effect for a cohesion performance relationship. Others who have examined interactive groups found a more positive relationship (Williams and Widmeyer, 1991; Mullen and Cooper, 1994; Widmeyer and Martens, 1978) therefore with such varying results, the other factors of cohesion may be more appropriate to explaining the cohesion-performance relationship. In a similar vein to the interacting – coacting hypothesis,
Personal factors relate to more specifically the individual within the sporting group (Weinberg and Gould, 1999). These may come in the form of motivation, satisfaction or commitment (Carron and Dennis, 1998). The relationship between motives and cohesion level was examined by Eisler and Spink (1998), in which the psychological motivation was measured for a group of intercollegiate basketball players. Eisler and Spink supported the belief that the cohesiveness of a team around a task may influence to an extent the perceived psychological motivation in a neutral or a positive situation. In translation towards sporting environments and the predicted cohesion-performance link may be effected by motivational factors. This was backed up by Widmeyer and Williams (1991) who found that member satisfaction was the major determinant of both task and social cohesion amongst golfers. Williams and Widmeyer (1991) highlighted that motivation of individuals may also be a problem that has to be addressed.
The motivation problems may arise from the perception of the task. Perception of the task ahead may possible influence cohesion and also the individuals perception of cohesiveness may be related to an adherence issue factor (Prapvessis and Carron, 1997) such an adherence issue may be more applicable in the formation stages of a group. However problems with perception of cohesiveness may be that of an expectancy effect, which may underestimate any challenges to cohesion (Dirks, 2000). However personal factors may also include such factors as anxiety, which to an extent may be detrimental to performance. (Weinberg and Gould, 1999) Prapavesis and Carron (1996) found that C.S.A.I (Competitive State Anxiety Inventory) A-state responses were a consequence of cohesion.
It must be addressed that some individuals do not just participate for the success, they may participate for the social for the enjoyment and although this may possibly cast doubts over the sources of cohesion, but as Donnelly (1994) highlighted that sports groups are more than reflections of society they are actually the creation of people.
Team factors relate to the stage and status of the group (Carron and Dennis, 1998). Teams may exist in a minimal form, however Tuckman (1965) suggested that every team would undergo the same 4-stage development process to ensure its survival:
Forming: The formation stage is the initial “come together” of the group members who wish to form a team. Members of the team consider social comparisons or evaluations within each other to find the strengths and weaknesses of each individual (Weinberg and Gould, 1999). During this stage outcasts often find themselves pushed away from the group. Trials at football or any other sporting institution may be viewed as a formation stage, as those who manage to process through the initial stage would be classed as successful trialists or applicants. It is only once the forming stage has been established that the interpersonal skills / relationships and indentifications are formed (Weinberg and Gould, 1999).
Storming: The next stage consists of the brainstorming session which could be referred to as storming, and this stage is often characterised by a rebellion within the group. Natural leaders will be become apparent and routines established to attempt to curtail any such rebellion by the group individuals. Tempers and relationships between members often become frayed during this stage as battles for places in the team and for natural leaders to establish themselves within the still developing group. Weinberg and Gould (1999) suggest that during this stage it is important that the coach should try to communicate with the members of the group.
Norming: Consisely, norming is the situation were conflicts within the groups are resolved and the team begins to emerge from its scattered framework. Although during this time, processes which may ultimately increase performance in the long run may become apparent via use of individual contribution awareness (Anshell, 1994).
Performing: In this stage team members band together to channel their energies for team success (Weinberg and Gould, 1999). It has to be remembered that a team is an actual process and though at any stage it could lose an individual.
As Tuckman suggested that the 4 stages of development exist, it is believed that the complex interaction of players, coaches and performance may unwittingly influence cohesion (Brawely, 1990). Throughout the formation of a team, teams show different levels of cohesion throughout development. A team although has to survive and work together in order to establish success. It is feasible to expect those teams in the initial stage of development to show a lower level of performance as all constituent parts of the team are being formed. Research about the changes of cohesiveness and performance during the different stages suggested by Tuckman (1965) remain elusive. This could possibly be due to an inconsistent nature of a group during its development, due to transfers or squad rotation. Such a long-term stable experiment may not therefore be plausible.
Leadership factors may include the leadership style adopted and the behaviours that the leader exhibits (Weinberg and Gould, 1999). Carron (1993) suggested that clear communication would ultimately increase cohesion amongst the group. Different styles of leadership may be adopted by the leader of the group, such styles may be autocratic, democratic or laissez faire. Research into the effects on the different types of leadership on cohesion was carried out by Carron in 1988 and he found that a democratic style was more suited than that of an autocratic style, however it may be believed that a laissez faire approach may increase social cohesion but actually decrease task cohesion and therefore influence performance. Other factors such as trust towards the leader have been investigated, Dirks (2000) investigated trust and found a positive relationship between trust and team performance, in linkage with cohesion it could possibly substantiate beliefs that a more cohesive group is a more trustful group.
When looking at cohesion, authors have been quick to suggest that a higher level of cohesion leads to a more advantaged performance (Widmeyer et al., 1993). Although the direction of causality approach may ultimately suggest that is it an increased performance which that produces increased cohesion or is it increased cohesion, which produces increased performance, (Weinberg and Gould, 1999). This could possibly discount all previous research despite the authors having highlighted the area. A possible way to combat these thoughts would be to address pre and post tests in regards to cohesion to see if performance outcomes do actually affect the cohesion levels and would link into the direction of causality concern. Despite its possible damaging effect the direction of causality could have on researchers thoughts and attempts to control this, it does provide an opportunity to extend knowledge towards performance outcomes and the effects it may have on cohesion levels which in turn effect performance. It could remain be a forever changing perspective with its resolve being the ultimate answer to any cohesion performance linkage. This follows thoughts by Grieve et al., (2000) suggested that the task cohesion and performance reciprocally influence each other. Whereas Kozub and Button (2000) questioned which factor effects the other.
When measuring cohesiveness during each of the study’s problems may have arisen. Usually the cohesion is measured by the G.E.Q (Widmeyer et al., 1985), using this method was highlighted as a possible problem within studies (Brawley, 1990). This was pointed out, as it was unknown when the effects of cohesion on performance would be noted or become difficult to highlight specific changed when using a correlation system, which is often adopted during many tests.
Although a more recent study by Li and Harmer (1996) proposed that the GEQ has adequate factorial validity for measuring group cohesion. Li and Harmer had acted upon claims by Schultz et al., (1994) that the GEQ was an invalid measurement tool for group cohesion.
In conclusion it has been shown that an effect for the cohesion-performance linkage does exist, (Mullen and Cooper, 1994) although the extent to which has been discussed (Grieve et al., 2000). It was also found that the relationship between cohesion and performance may have been effected by such factors as suggested by Carron (1982). Problems arising from a causality effect were discussed and it still remains unclear as to which variable actively effects the other. Other limitations regarding administration of the questionnaire for measurement of cohesion have been discussed and the validity of the G.E.Q has been discussed (Brawley, 1990). Overall it may be concluded that research still remains open to the full extent of the relationship.
For future research in this area, the causality effect should be investigated and also authors should attempt to move away from correlational studies, to try and establish more viable results. Research should also be encouraged to examine further the differences between group types (interacting or coacting). Any further research would therefore enhance the understanding between the link of cohesion and performance.
