After 8 weeks of intervention, data were collected and analyzed by Chi-square, independent t-test, and one-way ANOVA with repeated measures using SPSS software version 17. Results: Mean depression scores decreased significantly (p<0.001) in the intervention group (13.36±2.23 to 8.72±3.71). Also, mean depression scores decreased (p>0.05) in the control group (13.25±2.04 to 11.78±2.93); however, it was not significant. The comparison of depression scores did not indicate a significant difference regarding the reduction of depression after intervention between the two groups (p=0.08). Conclusion: According to the findings of this study, administration of omega-3 capsules (2gr/daily) for 8 weeks decreased menopausal depression. However, there was not a significant difference between omga-3 and placebo groups in this study. For a more precise observation of the effects, further studies with longer periods of intervention are needed.
