A construct validity study of the Survey of Perceived Organizational Support.

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