Meyer, Becker, and Vandenberghe (2004) recently proposed a model linking work motivation to organisational commitment. Two studies tested these links prospectively with employees from a Canadian telecommunications company and from an Italian autoparts company. Self-determination theory provided the framework to measure work motivation, such that measures of external, introjected and identified regulation, and intrinsic motivation were linked to Allen and Meyer's (1990) and to O'Reilly and Chatman's (1986) tripartite models of organisational commitment. We hypothesised that Time 1 motivation would be related to changes in commitment over time, but that Time 1 commitment would not be related to motivational changes over time. Results supported hypotheses for affective and normative commitment, but not for continuance commitment.Organisational commitment has become an important concept in organisational behaviour over the past few decades. It is defined as a psychological state or a force that binds the individual to a target, in this case the organisation Meyer, Becker, & Van Dick, 2006). The breadth of this definition has allowed researchers to examine different types of commitment to organisations, their development, and their effects on people and organisations. Allen and Meyer (1990) proposed a tripartite conceptualisation of organisational commitment. Affective commitment is defined as the emotional attachment and identification a person has to an organisation, and that person's involvement in that organisation. For example, one can feel proud to be a member of organisation X and truly want X to be successful. Normative commitment is defined as a feeling of obligation or loyalty toward an organisation. For example, one can feel loyal to a family business or indebted to

MOTIVATION AND COMMITMENT INFLUENCESan organisation because it has paid for one's education. Continuance commitment is defined as the perceived cost of leaving an organisation. For example, one can stay in an organisation in order not to lose a good pension plan, or because one has poor job alternatives (Meyer, Stanley, Herscovitch, & Topolnytsky, 2002). O'Reilly and Chatman (1986) proposed a different tripartite conceptualisation of organisational commitment based on Kelman's (1958) theory of attitude change. To them, organisational commitment is the attitude one has about the organisation that can develop through one of three mechanisms. The first mechanism, identification, represents feeling like an integral member of the organisation, having a sense of belonging, and a sense of pride. The second mechanism, internalisation, represents acceptance of organisational values, and a willingness to adhere to these values at work. The authors often merge these two subscales to form a single dimension that they call normative commitment. In this paper, however, we will give it a different name to avoid confusing it with Allen and Meyer's (1990) normative commitment concept, and call it integrative commitment. The third mechanism, instrumentalit...
