This study examines destructive leader behaviours among a sample of Iranian leaders. Destructive leader behaviour was measured using the Destructive Leadership Questionnaire (DLQ) developed by Shawet al.(2011). Data from 700 Iranian subordinates who completed the DLQ were used to identify the dimensions of destructive leadership using principle components factor analysis. The factor analytic data were used to develop an Iranian version of the DLQ. Behavioural scale scores were then used to identify a typology of destructive leaders in the Iranian sample.
