Compared the Beck Depression Inventory (BDI), the Guilford-Zimmerman Depression Scale, the MMPI Depression Scale, and the Multiple Affect Adjective Check List Depression Scale. 120 Egyptian college students were assessed. The intercorrelations between the scales were statistically significant and high. A general and highly loaded factor was extracted and accounted for 67.5% of the total variance. On the grounds of both brevity and internal consistency, the BDI outperformed the other 3 scales. (English abstract)
