Development of covert and overt hostility scales from the Buss-Durkee Inventory.

The purpose of this study was to develop covert and overt hostility scales from the Buss-Durkee Inventory. First, 22 covert hostility and 29 overt hostility items were identified by the authors. Second, an item analysis was done to assess the content saturation of the individual items on these scales. This analysis yielded the final form for 7 items for covert hostility and 14 for overt hostility. Cronbach alphas for the covert and overt scales were .67 and .77, respectively, and their intercorrelation was .08. Correlations for these Buss-Durkee scales with several existing measures of anger expression were consistent with expectations.
