Domestic violence (DV), also known as intimate partner violence (IPV) (
1), is defined as the behavior within an intimate relationship that causes physical, sexual, or psychological harm, including the acts of physical aggression, sexual coercion, psychological abuse and controlling behaviors (
2-
4). Violence against women takes various forms according to different societies and cultures, but its existence is a social fact that is found in all social classes, cultures, religions and geopolitical situations (
5,
6). Unfortunately, this means that DV against women is a worldwide phenomenon and therefore, a global public health problem due to the effects it has on women’s health. The invisibility of the phenomenon is due to the fact that women have difficulty in voicing their problems (
4,
5,
7). It is known throughout the world that domestic violence is a generalized phenomenon that has negative effects on the life and health of women. Women who have suffered from DV are at higher risk of depression, chronic pain, psychosomatic disturbances, physical injuries, gastrointestinal disorders, posttraumatic symptoms, poor pregnancy outcomes, sense of helplessness and worthlessness , and others (

8,
9) which may, in turn, lead to self-destructive behaviors such as smoking, heavy drinking, or suicide. As such, in 1996, the World Health Assembly Resolution (WHA) stated that preventing violence against women is a public health priority (
5). Worldwide population surveys among women indicated that between 10% and 50% were, at some stage, abused by an intimate partner (
1). Iran shares the widespread social problem of high incidence of DV with developed countries (
10). Thirty percent of married women reported at least one act of serious physical violence during their marriage according to a National Survey on DV against Women (NSDV) conducted in 28 provinces of Iran (
10). However, it remains invisible and under-reported (
7,
10). In all societies, DV is difficult to study because it occurs primarily within the private sphere of the family. Many women are reluctant to report their abuse because of the stigma, self-blame surrounding the experience, fear of possible repercussions from perceived disloyalty to their spouse and family, fear of losing their children, feelings of shame, denial, or fear of being negatively judged by others, guilt regarding DV, or the lack of personal resources to either leave the home or change the situation (
9,
11,
12). This is not surprising given that Iran’s society is still dominated by traditional values including a patriarchal family structure and the social requirement that women should accept and tolerate DV in silence (
10). However, incidence rates of DV in Iran are likely to be underreported due to expectations that women maintain secrecy about DV. Lack of knowledge about women’s legal rights and their shame in reporting the abuse to police are some of the most important hindrances (
13).
At the individual level, these factors might include sociodemographic characteristics, such as women’s age, education, employment, health status, and experience of violence in the family of origin or present extended family household (
11). A qualitative analysis of battered women found that women’s primary objective was to find ways of achieving non-violence rather than ending the relationship (
12). Private strategies used by women to manage and reduce the violence include deciding to remain in the relationship while disengaging emotionally from the partner, remaining vigilant of the partner’s behavior and planning to do something only when the violence becomes more serious, resisting or fighting back, placating the partner, avoiding him, or actively silencing themselves (
3,
12). However, researches show that DV is one of the main reasons given by couples seeking divorce (
14,
15) and more than half of cases entering divorce mediation report having experienced DV (
16-
18). Also, research suggests that 38% to 43% of women with DV separate or divorce after a 2-year follow-up (
19). A question that is posed here is: what personality traits that can influence the decision to remain in the relationship or to ask for a divorce? To answer this question, we studied the effect of two personality traits: self-concept and self-differentiation.
Self-concept defines how we value ourselves. In general, self-concept can be defined as an organized entity of characteristics, features, standpoints, emotions, images and abilities that the person ascribes to himself or herself. These psychological entities form the so-called referential frame with which an individual coordinates and orients his or her behavior (
20). Thus, self-concept is a psychological construct through which we perceive ourselves, the way we see ourselves and the way others see us, and how we behave accordingly. Self-concept develops during our interactions with others. The concept also comprises the ability to think about what we are likely to do in a given situation (
20,
21). Self-concept refers to an individual’s perception of self in relation to characteristics such as academics, gender roles, sexuality, communication with other people and racial identity (
20,
22). Self-concept develops over a lifetime and varies among individuals. As defined by Bracken (1992), self-concept is a learned response pattern that reflects the individual’s evaluation of past behavior and experiences and predicts the individual’s future behavior (
22). Also, Differentiation of self is an important familial factor that has been found to be related to stress and anxiety (
23) .Differentiation of self is the internal, psychic condition of being able to distinguish feelings from thoughts. Differentiation is described on a continuum where at one end (high differentiation) an individual is able to maintain a strong sense of self in the midst of uncertain circumstances and intense emotional relationships. At the other end of the continuum (low differentiation), a person loses self in situations that produce anxiety, becoming emotionally dependent and enmeshed or fused psychologically with others (
24). Bowen believed that the level of differentiation persons achieve in their family of origin has an important and lasting effect on their life (
25). Also, studies have shown that differentiation of self has been positively correlated with psychological well-being, ethnic belongingness, self-control, and marital adjustment; and negatively correlated with chronic anxiety, psychiatric symptoms, fears of abandonment, and desire for merger (
25). More differentiated persons are expected to establish greater autonomy in a relationship without experiencing debilitating fears of abandonment and to achieve emotional intimacy in that same relationship without fear of feeling smothered. It is also the case that those with higher levels of differentiation are expected to act from their values and sense of self rather than be influenced by the emotional reactivity of others. Thus, a more differentiated partner will be able to separate out the anxiety due to symptoms and will be able to act toward the other in ways that would maintain relationship satisfaction and be supportive of one another (
26). Bowen says that low differentiation levels contribute to marital conflicts. Haber (
27), for example, found that couples with higher levels of differentiation had lower levels of relationship conflicts. Another study of married couples also found a significant relationship between differentiation and marital satisfaction (40). In a similar vein, Skowron (
28) found a positive correlation between differentiation and marital satisfaction, with husbands’ emotional cut-off scores particularly correlating with both husbands’ and wives’ marital satisfaction scores. The study showed that the couples who have low levels of differentiation and high levels of emotional reactivity, and cut off and fusion with others experience higher levels of stress and anxiety in their relationships. These couples are less satisfied with marital too (
29). As mentioned above, previous researches have shown that DV has a deteriorating influence on society by affecting victims, their children, families and friends, as well as the social and financial relationships. In fact, several researches and studies have been performed on the factors affecting DV such as socio-demographic characteristics, psychological and cultural factors. In this research, we examined the personality characteristics that influence the decision to remain in this destructive relationship.
