The Arabic Children's Depression Inventory and the Beck Depression Inventory were administered to 109 Kuwaiti school students whose ages ranged from 14 to 18 years. Pearson correlations for total score on the two scales were .57, .83, and .75 for boys, girls, and the combined group, respectively, denoting the convergent validity of the new Arabic inventory against the Beck Depression Inventory as criterion.
