The overall assessment of the couple's marital satisfaction and meeting their needs and demands (
1) have a deep association with their psychological, emotional, and physical aspects (
2). Marital dissatisfaction is developed through negative feedbacks from couples’ conflicts and ignorance of partner’s emotions (
3). Attachment is a specific behavioral pattern that is crucial for the development of a healthy personality. Secure attachment occurs when a mutual and pleasurable state develops between the couple. This warm, sincere and lasting relation is satisfactory for both partners (
4). Hazan and Shaver studied the nature of intimate bonding and the role of mental attachments among adults. The results showed that the characteristics of the bond with emotional ties between couples are comparable to the characteristic of the child-mother bonding. Known attachment styles includes secure, insecure, and ambivalent that affect couples’ thoughts, feelings, and behaviors in marital relationships (
5). Hazan and Shaver stated that attachment styles reflect the fundamental differences in mental imagery representing romantic love.
Securely attached people describe their love experiences as joyful, reliable, supportive, and pleasant. On the other hand, insecurely attached individuals describe their love experiences with a fear of intimacy. People with ambivalent style describe their experiences as obsessive with extreme jealousy and intense sexual attraction. These researchers have shown positive correlation between attachment styles and marital satisfaction, and a negative correlation between insecure attachment and marital satisfaction (
6,
7). The research on attachment shows that insecure attachment is highly related with alexithymia (
8,
9). Feeling insecure in attachment relationships predicts defects and failure in identifying and expressing emotions (
8). Based on other research in this field (
10-
12), subjects with secure attachment style have less interpersonal and marital problems in comparison to subjects with insecure and ambivalent attachment styles.
Therefore, people with secure style by expressing intimacy and emotions about love and friendship, create a situation, which leads them to feel more satisfied. While those with insecure and ambivalent styles report the quality of marital relationship as negative, emotionally distancing, and anxious (
13). One of the variables studied in relation to the human emotion is alexithymia that has a direct effect on mental functioning. When people have the emotional capacity, they can meet the challenges of life while improving their mental health and life satisfaction. People who are weak in identifying and using emotions may lack the ability to take advantage of their emotional world; therefore, they fail to experience positive emotions such as happiness which are low in these people (
14).
Effective communication has a prominent role on marital satisfaction (
15) and could have an important role in creating security for couples (
16). Emotional expression is a fundamental factor in the differentiation between unhappy and happy couples, because it plays an important role in the development of intimacy in a relationship (
17,
18). Mutual expression of affection creates a sense of support and increases self-revelation in couples (
19). The study results showed that self-revelation behavior of couples has a positive correlation with marital satisfaction (
20). Also, emotional skills and the ability to express emotion have a positive correlation with marital satisfaction (
21). The study results confirm the relationship between alexithymia and avoidance of intimacy (
22), suggesting that people with alexithymia, have a strong need for independence, which results from their doubt and mistrust in others (
23). On the other hand, people’s mental and physical well-being are significantly influenced by their close relationship. Ability to establish and maintain a satisfying romantic relationship requires the ability to identify emotions and feelings and express them (
24,
25), as well as the ability to understand and appreciate the feelings of others (
26). Results showed that alexithymia has a positive relationship with difficulty in communicating and getting close to others, and the need for being approved by others. However, it has a negative relationship with trusting others (the characteristics of insecure individuals) (
27).
Evaluating factors associated with marital dissatisfaction seems necessary because the role of marital satisfaction is important in mental health, physical health, efficiency, productivity, and social contributions of the spouses. Couples, who perceive marital dissatisfaction, undergo a lot of stress and suffering.
