Finally, data was analyzed via SPSS-18. Results: 12.9% of study population had major depression; %24/9 and% 45/1 of were rated as middle a mild depression, respectively. The BDI showed significant positive internal consistency (Alpha=0.92) and test–retest reliability (r=0.64), Intra-class Correlation Coefficient (ICC=0.81), convergent validity with GHQ-28(n-209) was significantly positive(r=0.80) Conclusion this study indicated that the Iranian version of the BDI-II is valid, reliable and appropriate instrument for screening depression in elderly.
