The authors report a series of 9 studies (N = 2,734) in which they eva
luated the construct definition, measurement, and validation of organi
zational commitment (OC). An integrated examination of a wide range of
antecedents of the various dimensions of OC was conducted. Results su
pport the existence of 3 major OC dimensions (affective, continuance,
and normative), with 2 subdimensions (personal sacrifice and lack of a
lternatives) for the continuance dimension. Results suggest that the w
idely used Organizational Commitment Questionnaire assesses primarily
the affective dimension. Results provide various levels of support for
the set of proposed antecedents. Implications for construct definitio
n, measurement, and future research are discussed.
