Marital relations constitute a major part of human life and strongly determine life satisfaction. Acquiring accurate information about the skills of marital relationship improvement, reinforcing a sense of responsibility toward one’s sex life, and gaining further awareness about healthy sexual relations help couples form energetic marital relations (
1). The quality of marital relations is expressed through concepts such as adjustment, satisfaction, happiness, and evaluation. Marital adjustment refers to couples’ satisfaction with and happiness in their marriage (

The marked rise in marital conflicts in the modern world and the risk and consequences of divorce for the mental health of couples and children have led counselors and family therapists to examine various theories to improve major family functions (
3). To this end, family therapists have proposed different views and theories to enhance family functions, attempting to identify and improve the dysfunctional patterns that cause conflicts in family relations by analyzing communication and interaction patterns in families (
4). Evidence suggests that dissatisfaction with marital relations and an emotional breach between couples increase the risk of divorce (

6).
Intimacy is a major variable in marital relations. As intimacy is more fundamental than other human needs, promoting intimacy between couples is the first step toward an optimal marriage. Intimacy is the core of romantic relations, and researchers have conceptualized this construct (
7). For instance, Kardan-Souraki et al. (
8) consider intimacy to consist of nine dimensions, including emotional, social/recreational, sexual, intellectual, psychological, physical, spiritual, aesthetic, and temporal dimensions. Intimacy problems are an important reason for seeking marital counseling, and promoting intimacy is often a goal of couples therapy and marital counseling. Intimacy is a deep, potent human need with an intrinsic origin, which is rooted in the need for attachment and is based on mutual respect and trust (
9). According to the literature, marital intimacy is a major contributing factor to stable marriages, and a lack of intimacy in marital relations leads to failed marriages (
10,
11).
Marital harmony is another determinant and influential factor in the success of marital relations, which has been investigated in the present study. Marital harmony pertains to couples’ orientation toward daily changes and encompasses the regulation of couples’ lifestyle to manage life challenges (
12). Harmony refers to a situation in which couples can exchange ideas and resolve the causes of their dissatisfaction. Maintaining harmony in marriage is essential to having a healthy family (
13). Marital harmony is affected by factors such as couples’ expectations of each other, parenting styles, financial issues, friends and acquaintances, sexual relations, and relationships with relatives and family members. It is an extremely important, yet highly challenging topic in the domain of family counseling (
14).
To date, researchers have adopted several approaches to improve marital intimacy. Such an example is the emotionally-focused approach, which is mainly focused on the nature of emotion as a key and potent factor of change in couples therapy (
15). Emotionally-focused couples therapy is influenced by systemic therapies as it is based upon the fact that marital problems and conflicts arise from the interaction patterns/cycles between family members/couples. This therapy is a valid experimental approach to couples therapy and relies on the theory of attachment and understanding couples’ needs. The therapeutic goals of this method include fostering a safe and powerful bond between couples.
Emotionally-focused therapy highlights the integration of emotion, cognition, motivation, and behavior, which are activated by the therapist to modify emotions (
16). In this method, the identification and improvement of emotion schemes are of utmost importance. Change requires a gradual process of emotional activation, which is mainly achieved by using specific techniques to overcome avoidance, reduce disruptive behaviors, and facilitate emotional improvement. Therapists help patients identify and express their primary feelings and access their intrinsic capabilities (
17). This model distinguishes between primary and secondary emotions and also divides these states into structured, adaptive, maladaptive, complex, and social emotions.
Previous studies have confirmed the effectiveness of emotionally-focused couples therapy in the marital and family context and the mitigation of relationship distress. According to Wiebe et al. (
18), this therapy helps couples foster safe attachment bonds and promote intimacy. In another study, Tie and Poulsen (
19) reported that emotionally-focused therapy was effective in improving couples’ relationship, reducing marital conflicts, and increasing marital harmony. Furthermore, Zanganeh Motlag et al. (
20) stated that acceptance and commitment therapy and emotionally-focused couples therapy could both effectively enhance marital intimacy, commitment, and psychological flexibility. Therefore, exploring the effects of emotion-based couple therapy on improving marital intimacy and harmony were the key purposes of our study.
