Marriage is a social, cultural, and biological event (
1) and in many communities, it is considered a milestone in a couple’s life (
2). Success in marriage and the feeling of satisfaction due to its role and its importance in the health of the society have been the subject of many papers in the field of social sciences. Results of the conducted researches showed that personality characteristics are the most important factors in the formation, success and demise of family relationships, which affect the way the couple interact and understand each other (
3). One of the important variables in a couple’s relationship is the level of emotional maturity, which can indicate the couple’s level of differentiation (

Emotions shape our psychological and social life and the way a person controls his/her emotion and provide a foundation for mature relationships. Emotional maturity is defined as how well a person is able to control emotions, react to situations, and interact with others (
5). The ability to communicate properly, accept responsibility and successfully interacts with the society (
6) and is the key to a satisfying happy life. Couples of the new generation are less satisfied with their marriage in comparison to couples in the older generation (

Bowen (1978) has addressed the concept of emotional maturity in the studies conducted in relation to marriage stability. Emotional maturity in an interpersonal dimension is the ability to experience intimacy without loss of individual autonomy (
8). The couple’s emotional maturity may improve family functioning (

10), marital satisfaction (
11), mental health and coping skills (

Mental health and emotional maturity have significant roles in creating necessary skills to interact and communicate effectively, social adaptability, problem-solving, and in coping with relatively minor problems (
13). Research results indicated that spouses with satisfactory long-term marital relationships are protected to some extent from the negative impacts of life stressors, while couples with unsatisfactory relationships are more susceptible to the negative effects of stress (

Based on the statistics obtained from Iran’s National Civil Registration Organization, in 2014, a total of 163,569 divorced cases have been registered in comparison to the extent of the same period last year (155,369 divorced cases) an increase of 10% has been observed. In this regard, the province of Alborz has a record of 6,194 cases of divorce with a growth of about 11% in comparison to the year earlier (5,663 divorce cases) (
15). Alborz province is the second most common province in regard of divorce cases after Tehran the capital city of Iran and poor communication skills with the lack of emotional maturity rank first among the other influences of divorce (
16). In Iran with a high record of divorce in the younger population, this could lead to an inevitable devastating effect on the physical and mental condition of the couple, children and the community in a way that incompatibility and dissatisfaction of the couple after marriage would result not only in mental and social have on the part of the couple but also cause adverse effects on the growth and development of their children.
