The survey of perceived organisational support: Which measure should we use?

Abstract

The psychometric properties of the original 36-item Survey of Perceived Organisational Support (SPOS) was examined along with a variety of shorter versions currently in use (16 items, eight items and three items). Factor analysis of the original SPOS measure is supportive of the original finding that the SPOS is unidimensional. Correlations among factor scores and SPOS scale scores suggest that either the eight-item or 16-item version would be just as effective as the 36-item version but even more efficient. Convergent validity results also indicate similar proportions of variance in versions of SPOS scores accounted for by selected organisational variables.
