relationship commitment

Although researchers working within the interdependence theory tradition

have argued that relationship commitment is multiply determined (Levinger,

1979; Rusbult, 1983; Sabatelli & Cecil- Pigo, 1985; Thibaut & Kelley, 1959), no

measure has been developed to assess these determinants. The present study

provides preliminary psychometric information regarding such a measure-the

Multiple Determinants of Relationship Commitment Inventory (MDRCI). Three

sets of findings from this study support the position that relationship commitment

is multiply determined. First, this study provided evidence from confirmatory

factor analysis that each of the six purported determinants of relationship

commitment derived from interdependence theory-rewards, costs, match to

comparison level, alternatives, investments, and barriers-were distinct constructs.

Because this pattern was crossvalidated across partners, the reported

factor structure can be assumed to be
