The purpose of the study was to construct a psycho-social model for team cohesion at a financial institution. The financial institution had been in existence for 127 years, and had faced significant challenges throughout its history of acquisitions and mergers to establish working teams that would give it a competitive edge in global financial markets. The research objective was to develop a psycho-social model for team cohesion by investigating the interrelationships and overall relationships amongst the independent constructs (self-worth, personality preferences and conflict resolution styles) and the relevant outcome (team cohesion). Furthermore, the study also scientifically tested the possible moderating effect of the employees’ socio-demographic characteristics (race, gender, age, level of education, job level and tenure) on the fostering of team cohesiveness. A quantitative cross-sectional survey design approach was selected and applied to a simple probability sample (N = 463) using standardised, valid and reliable measuring instruments. The population consisted of permanent employees, and the results revealed significant relationships between the construct variables. The canonical correlation indicated a significant overall relationship between the contingencies of self-worth domains, personality preferences and conflict resolution styles, and the team cohesion-related dispositions of cohesiveness and engaged. The structured equation modelling indicated a good fit of the data between the individuals’ contingencies of self-worth domains (family support, God’s love, virtues, competition, work competence, physical appearance and pleasing others), the accommodating conflict resolution style, an extraversion personality preference, and team cohesion. Hierarchical moderated regression showed that race, age, educational level and job tenure significantly moderated the relationship between the participants’ psycho-social attributes and team cohesion. Tests for significant mean differences revealed significant differences in terms of the socio-biographical variables. On a theoretical level, the study deepened understanding of the antecedent constructs (self-worth, personality preferences and conflict resolution styles) and team cohesion construct. On an empirical level, the study produced an empirically tested psycho-social model for team cohesion. This study will add significant practical, valuable knowledge to the organisation in managing the future establishment and enhancement of team cohesion, and when integrating new team members to the environment during organisational restructuring and re-alignment after acquisitions and mergers, without negatively affecting organisational effectiveness. These findings invariably provided new insight in managing and understanding inherent interpersonal conflict among employees in the workplace and the enhancement of team cohesion practices, thus adding to the existing body of knowledge in the fields of Consulting Psychology and Industrial and Organisational Psychology, more specifically in financial organisations. / Psychology / D.
