A CONSTRUCT-VALIDITY STUDY OF THE SURVEY OF PERCEIVED ORGANIZATIONAL SUPPORT

Eisenberger, Huntington, Hutchinson, and Sowa (1986) recently conducted a study focused on a measure of perceived employer commitment that they called the Survey of Perceived Organizational Support (SPOS). In the present study, confirmatory factor analysis was used to examine the dimensionality of the SPOS and to determine the distinctiveness of this construct from other similar constructs. Participants were 330 employees in a large corporation headquartered in the southeastern United States. The results support the SPOS as a unidimensional scale that is distinguishable from affective and continuance commitment. However, the data raise some question as to the empirical distinction between the SPOS and satisfaction.
