Seven experiments constructed and validated the Arabic Children's Depression Inventory (ACDI) defining the ACDI's factorial structure, the appropriate response format to its items, its reliability estimates, and the Arabic norms of the ACDI. The correlation between the ACDI and personality was determined, and an English version of the ACDI was set up. 2,558 Arabic children (aged 11–15 yrs) participated in the study. The ACDI's final form containing 27 items have to be responded through 3 alternatives: rarely, sometimes, and often. ACDI has good face validity, internal consistency, and stability over time. Factor analysis yielded 7 factors: unhappiness, sleep problems, loneliness, sadness, pessimism, weak concentration, and weakness. The significant, positive, and high correlations between the ACDI and both the Children's Depression Inventory and the Hopelessness Scale for Children support the concurrent validity of the ACDI.
