The composite measure of the defense mechanism inventory

Samuel Juni

Research output: Contribution to journalArticlepeer-review


A reanalysis of previously published data suggests that the Defense Mechanism Inventory can be utilized to yield a composite measure of reaction to frustration by contrasting linearly the defenses of Turning-against-object and Projection against those of Principalization and Reversal-of-affect. Factor-analytic and correlational data support the exclusion of Turning-against-self from the composite measure. Studies of content validity are presented for the combination of the four defenses into one dimension. Patterns of interitem reliability are charted for the five defenses and the composite measure for both men and women. Internal consistency data are also presented for the standard scoring as well as for a modified method to explore the feasibility of simplifying and shortening the test-taking procedure.
