In this study the researcher explored teamwork, specifically team cohesion and team identification, as moderators in the relationship between Organizational Citizenship Behaviors (OCB) and Psychological Capital (PsyCap). This research examined how teamwork can strengthen the influence of PsyCap on OCB, so that organizations understand the effect of team identification and cohesion to create a friendly and positive work environment that is conducive to producing more organizational citizenship behaviors from employees with higher psychological capital. A total of 175 valid respondents from 50 real estate teams participated in this study. Hierarchical Linear Models and Hierarchical regression was adopted to test hypotheses. As the research result shows, PsyCap has a positive relationship with OCB. Team Identification and Team Cohesion does not moderate the effect of Psychology Capital on Organizational Citizenship Behaviors both in team level and individual level. However, team identification and team cohesion has a significant relation to organization citizenship behaviors in real estate agencies.
