The aim of this article is to investigate the relationship between organizational commitment profiles and organizational citizenship behavior (OCB) and life satisfaction. To complete these goals three studies were conducted. The research involved the cultural adaptation of the internationally accepted standard Organizational Commitment Questionnaire and the development of the Organizational Citizenship Behavior Questionnaire. The first study (N=40) focused on the validation of translation and cultural adaptation of the Organizational
Commitment Questionnaire (Meyer & Allen, 1991, 1997). The second study (N=222) was aimed at confirming the factor structure and psychometric properties of the Organizational Commitment Questionnaire – Polish version. In the third study (N=42) the Organizational Citizenship Behavior Questionnaire was obtained. In the next study (N=503) the main research hypotheses were examined. Five clusters were identified using k-means cluster analysis. These were labeled: Non-committed, Neutrals, Enthusiasts, Trapped and Devoted. Analysis of variance results indicated that Enthusiasts and Devoted demonstrated the highest levels of OCB and high levels of life satisfaction. The Non-committed profile showed the lowest level of OCB combined with low levels of life satisfaction.
