Introduction: intimate partner violence (IPV) in pregnancy is considered as an additional threat to the maternal/fetal health. The present study was aimed to investigate the effectiveness of training problem-solving skills on IPV against pregnant women.

Methods: the present randomized clinical trial was conducted on 125 and 132 women visiting the health centers of Tehran as the intervention and the control groups, respectively; samples were selected using random stratified cluster sampling. The intervention group underwent four problem-solving training sessions. Three months later, both groups completed the revised Conflict Tactics Scale questionnaire. Data were analyzed using SPSS v.16.

Results: the mean (SD) ages of the participants were 27.51 (4.26) and 27.02 (4.26) years, respectively, in the control and the intervention groups. The rates of the physical and psychological violence were significantly reduced after the intervention in the intervention group. Risk differences of the physical, psychological and sexual violence before and after the intervention were 3% (95% CI: -8.23 to14.13, P = 0.6), 1.5% (95% CI: -4.93 to 8.03, P = 0.6) and 4.8% (95% CI: -7.11 to 16.52, P = 0.4) in the control group and 8.8% (95% CI: -3.47 to 20.71, P = 0.1), 25.4% (95% CI: 15.77 to 34.66, P < 0.001) and 4.9% (95% CI: -7.38 to16.97, P = 0.4) in the intervention group, respectively.

Conclusion: it seems that training this skill as a part of the routine prenatal care could be effective in reducing intimate partner violence.
