Violence against women is a form of gender-based violent behavior that causes physical, sexual or psychological harm or suffering of women. Such behaviors can be accompanied by threats, coercion or deprivation of freedom and liberty. Violence against women as a global phenomenon experienced in the private and public areas of life is a serious threat to health and human rights. This annoying behavior by a husband against a woman occurs in the privacy of the family and away from the eyes of the people of the community and often occurs secretly, which can be lead to physical and psychological harm to an individual, and also causes irreparable social consequences [1][2]. According to the World Bank, domestic violence is more likely to endanger the health of women aged 15-44 than diseases such as breast cancer, uterine cancer and accidents [3]. Cancer has always been the most important of all diseases. The kinds of cancers, for instance, breast cancer, ovarian cancer, lung cancer, gastric cancer and brain cancer [4][5][6][7][8][9][10]. Considering the types of violence against women is the most common type of domestic violence, with 90% of the victims of domestic violence being women [11]. According to the World Health Organization (WHO), in 2016, one- third women aged 15-49 were at risk of physical and sexual violence (13), which is in different regions, the WHO estimates the rate of violence in the Southeast Asian region was 38% [12][13]. In several studies in Iran that reported violence rates between 6% and 95% [13][14][15][16]. For example of this study, Hajnasiri et al. (2016), the rate of violence in the whole country was reported by 66%. Geographically, the rate of violence in the east and south of the country was 70%, 59% in the center of the country, and in the west and north of the country were 75% and 62% respectively [16]. In another study, Hosseini et al. (2013), a total of violence rates in Sabzevar was reported at 78%. Considering the types of violence, psychological violence (66.5%), Sexual violence (57%) and physical violence (35%) were the most common forms of violence [17]. In another study of Asadi et al. (2013) in Sabzevar, the total of violence was reported at 76.7%, and the verbal violence (97%), sexual violence (64%) and physical violence (54%) were the most common forms of violence [18]. Domestic violence against women imposes many negative consequences on the family and even the men themselves; include genital tract bleeding during pregnancy, low birth weight, wound, cuts, bruises, internal injuries, brain damage, genital damage, abortion and sexual diseases, depression, perceptual disability, weakening of self confidence, inadequate family management, avoidance of social participation, weakening of the motivation for progress and efficiency in the workplace, occurrence of physical and psychological pains (headache, back pain, inaccurate pain and chronic and psychological fatigue) and finally, the increasing collapse of families and divorces. Death is the worst harm caused by domestic violence against women [19][20][21].

Domestic violence has a huge impact on the quality of life of women and the health of the family and has been neglected as one of the social issues. Planning for controlling violence require an accurate understanding and the study of the causes related with it. Since there are few studies in the country and especially in Sabzevar city. Therefore, this study was conducted to determine the degree of domestic violence against women and its effective factors in married women in Sabzevar.

This survey is across-sectionaland descriptive-analytical study. The population of this study was all married women in Sabzevar who had at least one year of their marriage history, had experienced domestic violence and were randomly selected to participate in the study. The case study was conducted with a confidence level of 95%(α=0.05) and the sample size was 384, which were selected by multi-stage cluster sampling. For this purpose, the city of Sabzevar divided into five areas according to the city square and from each area four streets were randomly selected and also from each street, two alleys were randomly selected. To complete the questionnaire after obtaining a certificate from the Sabzevar university of medical sciences in order to run the project, the target group was provided with a description of the aims of the study and how to complete the questionnaire, and the questionnaire was completed by the women himself. To collect data, a questionnaire adapted to the culture of the country was designed. Its validity was confirmed by the panel of experts and its reliability was confirmed by internal consistency(α=0.69-0.87,N=30,).The questionnaire consisted of two parts: the first part includes questions about demographic characteristics (age, duration of marriage, number of children, wife and spouse's educational background, type of marital and non-familial marriage, occupation of men and women). The second part includes questions about types of violence, factors affecting violence, the strategy of women in the event of domestic violence and the suggestion of factors to reduce violence by the government. To answer each of these questions, the Likert scale was used, which was scored as 1-5. Data were analyzed by descriptive and analytical tests using SPSS20 software (P<0.05 was considered statistically significant).

The average age of the women was 39.50 ± 10.93 years (R = 16-76) and the age of their husbands was 34.48 ± 10.27 years (R = 21-80) .The mean duration of marriage was 13.91 ± 10.54 years (R = 1-57). They had an average of 1.65 children (R = 0-8). 67.3% of them had familial marriages. Most of them were educated (76%) and most of their husbands (69%) had diplomas and higher than diplomas. The job of most of them (70%) were housewives and most of their husbands (62%) were freelancer. According to the average results of violence against women was reported by 85.40 ± 39.55 out of a total of 290 grades. Social factors (β = 0.072), family factors (β = 0.075), and related factors of couples (β = 0.640), which explained 39% of total variance of violence. Considering these factors, the effect of factors related to couples was higher than other factors (Table 1). The types of violence, legal violence (19%), verbal violence (18%) and emotional violence (15%) were the most significant type of violence in the community, respectively.

This study predicts 40% of violence against women, despite the possible contributing factors to domestic violence and the factors related to couples, which these results were consistent with the studies reported by Dolatian et al [22], and Mohammad et al [23]. In confirmation of these results, it can be said that using educational interventions for couples and related counseling, moderated the factors related to couples to prevent at least 40% of violence against women. The types of violence, legal violence (19%), verbal violence (18%) and emotional violence (15%) were the most significant type of violence in the society, which these results were consistent with the studies reported by Asadi et al [18], Derakhshanpour et al [24], and Narimani et al [25]. were similar the type of violence in society. However, the social issues, lifestyle and cultural can be influenced by the situations of cities and provinces, the results of this study can be different from other studies in other cities. This study showed that working and financial problems, lack of proper education and training of the spouse in the father's home, interference of the husband's family and directing them to the spouse in life were the most important causes of the domestic violence between the couples, which these results were consistent with the studies reported by Klomegah et al [26], and Boonzaier et al [27], matched the role of problems such as job and financial issues as factors associated with the introduction of violence. In addition, the results of this study which were consistent with the study reported by Masoumi et al [28], matched the effect of interference of husband's families, proper education and the training of the spouse and the direction of the spouse in life affairs.

Our results showed, one of the most important strategies of women in the event of violence was to talk and try to solve their problem with the husband at the right time, to forgive or give away the husband if he was guilty and accept the mistake and apologize if he was guilty. Thus, these results can be matched with the view that social psychologists believe that using correctly educating the strategies necessary to resolve family problems to prevent any possible violence against women. Although the need for the use of counseling and psychologists to facilitate marital communication has been emphasized, but the least strategy taken by couples was to refer to counselors or counseling centers for solving their problem, which these results were consistent with the studies reported by Shamsi et al [29], and Sudani et al [30]. As shown in this study, the highest rates of domestic violence occurred at a time when important decisions in life were taken only by the husband, and the lowest rate of domestic violence was occurred at a time when important decisions in life were taken by the couple. These findings also confirm the role of shared decision making, mutual understanding, and the use of shared views of husband and wife to resolve personal issues and decisions, which these results were consistent with the studies reported by Ver Steegh et al [31], and Robinson et al [32]. Also, as shown in these results suggest that mental support as well as decision-making on the basis of the common view of the husband and wife can play a vital role in facilitating the prevention of domestic violence against women, which we found in this study. In this study, 76% of participants reported satisfaction with their lives, which these results were consistent with the studies reported by Ham-Rowbottom et al [33], and Gillum, Tameka L et al [34], and in other studies, it may be different in the rate of life satisfaction. Because the increase in the rate of domestic violence in married women may be related to a decrease in life satisfaction.

In conclusion,Violence against women around the world is one of the priorities of public health. Although the results of the research and information collected have increased the awareness and sensitivity of the community to this problem of women's health, but shame, fervor and fear of women and the lack of accountability of the community health system have caused the silence and isolation of women victims and neglect of its consequences on their physical and mental health. The consequences of domestic violence on women's mental health include depression, anxiety, stress, suicidal behaviors, self-harm, and also the foundation of the family, which requires attention to the dimensions of the issue of domestic violence against married women. As the results of this study showed, issues such as family education and counseling before, during and after marriage, and also awareness raising for families with the social emergency system should be considered. Based on the results of this study, the development of strategic policies, such as smoking prevention, combating unemployment, solving economic problems, and training of husband and wife for life decisions can have a preventive role in domestic violence against married women which should be considered.
