Spouse selection is considered the most critical stage in the family life cycle, and it has some criteria such as physical characteristics, socio-economic status, education level, and family status (
1-
4). The criteria for spouse selection can be either intrinsic (physical attractiveness) or extrinsic (being intelligent) (
5). The theory of homogamy postulates that like attracts like, and every individual usually selects someone who is most similar to them concerning age, religion, nationality, and education (
6,
7). Some research has reported that despite changes in the rules for marriage with people of color over time, white women still tend to marry their peers (
8,
9). A study conducted on students in Nigeria found that having a similar education level was an essential criterion for spouse selection in 67% of participants (
10). Based on complementary needs theory, dominant people match with domineering, and those with a leader characteristic select submissive spouses. The biological perspective focuses on physical attractiveness and childbearing for spouse selection (
11-
13). Men and women whose criteria for selecting a spouse is to have a healthy and attractive spouse tend to choose spouses with more attractive faces. For example, the larger body woman in traditional African societies or having a moon face in China is desirable (
14,
15). In the south of Iran, Refahi et al. (
16) examined criteria for spouse selection among 543 couples with at least five years of marriage and divided them into two categories of content criteria, including age, education level, occupation, income level, mental and physical health, religion, and physical attractiveness, and process criteria involving skills in organizing the family system, communication skills, coping skills, problem-solving skills, and flexibility. The results showed that men observed the content criteria for marriage.
One of the psychological structures related to spouse selection is attitudes toward love. Love includes cognitive components (unread thoughts and constant mental preoccupation with the loved one) and behavioral components (being close together). The typology of love style based on Lee's love theory includes Eros (romantic love), Ludos (game-playing love), Pragma (logical love), Storage (friendship love), Mania (dependent love), and Agape (selfless love) (
17). In a study among couples on the verge of marriage in Tuyserkan City, west of Iran, 89.5% of the participants mentioned love and affection, 87.7% chastity, and 86.8% spouse's mental health essential criteria of marriage (
18). A study reported that men had a higher tendency toward Eros love than women, and attitudes toward Eros, Pragma, and Agape love were the strongest predictors of marital satisfaction (
19).
Another critical question is about the relationship between emotional maturity and criteria for spouse selection, but few studies have been conducted on this issue. An emotionally mature one knows all one’s emotions and feelings correctly and can provide appropriate emotional responses. The emotionally mature person has six major characteristics: taking responsibility (being aware of their privilege in the world and trying to take steps toward changing their behavior), showing empathy (feeling more concern for others and trying to find ways of helping), owning mistakes (apologizing when doing wrong), being unafraid of vulnerability (being honest about your feelings and building trust with those around), recognizing and accepting needs (helping others and recognizing their needs), and setting healthy boundaries (knowing how and when to define a line and not allowing others to cross it) (
20). Research on 100 Indian couples revealed that emotional instability, social maladjustment, and personality disintegration facets of emotional maturity most predicted the overall marital adjustment in married couples (
21). A study on a couple of people showed a negative meaningful relationship between marital satisfaction, emotional immaturity, and lack of independence (
22).
A construct related to personality and interpersonal processes is Early Maladaptive Schemas (EMS), defined as a broad, pervasive theme or pattern comprised of memories, emotions, cognitions, and bodily sensations, regarding oneself and one’s relationships with others. They are developed during childhood or adolescence, elaborated throughout the lifetime, and are dysfunctional to a significant degree. Schemas play the main role in shaping cognitive structures and act as filters to receive, organize, and process information (
23). Research on university students showed that rejection and abandonment as two early maladaptive schemas were the predictors of spouse selection (
24). The number of studies about recognizing criteria for spouse selection and understanding factors shaping these criteria in Iranian people is limited. In the current study, an attempt was made to investigate the predictive power of some variables, such as love or schema, about the process and the content dimension of selecting a spouse in people on the verge of marriage who were referring to health centers.
