Introduction:this study aimed to compare the effectiveness of mindfulness and emotion regulation training in the reduction of marital conflicts.

Methodology:the present evaluation was a quasi-experimental study with a pretest-posttest design and a control group. The population consisted of all clients who referred to Moein Counseling Center in Alborz province (Spring 2014) due to marital problems. Using the simple random sampling method, 45 married people were selected as the sample and divided into two experimental groups (15 participants in each) and a control group (15 participants). Mindfulness training sessions were held for the first experimental group and emotion regulation training sessions were held for the second experimental group while, the participants in the control group did not receive any training. The Marital Conflicts Questionnaire was used for data collection and the obtained data were analyzed through descriptive statistics and analysis of covariance.

Results: the results confirmed the main hypothesis of this study regarding the effectiveness of mindfulness and emotion regulation training in reduction of marital conflicts (p<0.001, F=43.41).

Discussion and conclusion: there was a significant difference between mindfulness training and emotion regulation training in the reduction of marital conflicts; thus, compared to the mindfulness training, emotion regulation training can be considered a more effective treatment of marital conflicts.
