Assessing Commitment in Personal Relationships

A modelfor conceptualizing relationship commitment is presented and the development of a measure corresponding to this model described. Commitment is considered as two constructs: personal dedication and constraint commitment. In study one, items developed for the Commitment Inventory (CI) were given to a sample of 141 subjects. Item analyses resulted in selection of the items for the inventory. In study two, 279 subjects yielded data used in further testing of the CI. Tests were conducted on the reliability of the subscales, the factor structure of the CI, and the associations between the CI and various other measures of commitment. Further, the CI was examined in relation to various demographic variables and various measures of other relationship constructs. Overall, the research demonstrated that the CI shows promise as a reliable and valid instrument for measuring commitment. Implications are discussed for both the CI and the concept of commitment.
