Researchers have recently focused on integrating motivation and commitment models and have presented mixed models. This research, for the first time, presents an integrated model of motivation (Self-Determination Theory) and commitment (Three-Component Model), from a person-centered view. This study was carried out using a two-step cluster analysis method including hierarchical method and optimization of the profiles distances on 306 knowledge workers of four Iranian organizations. The results reveal four profiles, named based on their characteristics, "people with diverse and mild motives," "motivated people with mild intrinsic motives," "motivated people with mild external motives," and "people with internal motives." The characteristics of these profiles are examined concerning motivation and commitment. The results of this research can help to expand the literature of the mixed models of commitment and motivation. They can also be helpful for managers in terms of recognizing the knowledgeable employees of their organizations and categorizing them in terms of motivation, commitment and personality traits.
