The two groups were not significantly differentat the beginning of the study in terms of demographic data (P > 0.05). At the 3-month follow up, thepain rate in the intervention group was significantly decreased from 4.47 to 4.09 (P < 0.0001).Furthermore in intervention group, the mean scores of anxiety intervention group were decreasedfrom 17.73 to 9.76 (P < 0.0001). Decreased Stress scores decreased from 15.52 to 9.52 (P < 0.0001),and the depression score from 17.66 to 10.45 (P < 0.0001).Conclusions: The findings of this study showed that psychological interventions reduced stress anxiety,depression as well as low back pain among Iranian nurses.
