Marital relation is one of the major fields of treatment in Psychology. This study had considered the variables which effect marital satisfaction, that are of the most important factors of mental health. Psychological treatments need these variables to be studied very well since among all of them, some are suitable for clinical intervention and training such as conflict re solution, problem solving, marital beliefs, communication, expressing affect and emotion, and anger control.  The effectiveness of training these skills has been considered in so many papers. Because of training all of these skills are impossible, this question appears that which field is more important to be trained. The main aim of this study was to introduce effective and trainable variables. Clearly making plan for training and treatment can be easier based on this study.
