People experience many changes throughout their lives. The most important developments are marriage, job selection, having child, and finally the abandonment of the house by children and retirement. The occurrence of any of these changes can be caused by conflict and a problem within the family (Shahverdi et al., 2015) . Several definitions of marital conflict are presented. Systemic therapists consider marital conflict as a struggle to seize bases and sources of power and eliminate each other’s privileges (Ahmadi et al., 2016) . Disagreement, difference, or incompatibility among spouses will arouse conflicts (Markman & Halford, 2005) . Fowers and Olson (1992) also find conflicting wives who are dissatisfied with their spouse’s habits and personality and have a communication problem in a variety of contexts. In other words, conflict arises when one’s actions and behavior interfere with other acts and behaviors of the others. In addition, when the two individuals get closer, the conflict force increases (Shahverdi et al., 2015) . Another factor that influences the strength and stability of families is mental happiness. A society can move towards its transcendent and ideal goals when the happiness is the continuous experience of its members, because happiness plays an important role in improving physical and mental health. A person who is happier is more relaxed and more secure, easier to make decisions, with more decent work, and more involvement and ultimately has a more satisfying life (Pressman & Cohen, 2005) . For this reason, today, studies on happiness and its related factors are among the most important priorities of psychology.
On the other hand, the marital relationship is one of the most intimate and most private forms of human communication, which is one of the innate human needs. Having a relationship with a spouse can be a source of comfort, support, and pleasure for everyone, while this relationship can sometimes be a source of anxiety, frustration, and dissatisfaction (Zeinali, 2014) . Various factors are involved in marital satisfaction, such as the quality of marriage relationships, marriage, communication practices, couples’ character, and ways to deal with marital problems that are well known in this field (Patrik et al., 2007) . Another factor is the sexuality and sexual issues of couples. Sexuality is one of the key elements of women’s global psychological well-being. Sexual disfunction also includes problems that affect the person’s sexual desire, arousal and ability to reach the orgasm, and this type of problems is also common during sexual intercourse. In other words, the definition of sexual disfunction is the destruction of one or more stages of the cycle of sexual responses, as well as the presence of pain associated with intercourse, which causes tangible distress and interpersonal problems according to DSM-IV-TR. Disfunction is widely defined as the inability to fully enjoy sexual intercourse. Specific sexual disfunction is disorders that interfere with a complete sexual response. These disorders create problems for enjoyment or sexual intercourse, which rarely endangers the physical health. However, it can cause psychological damage, depression, anxiety, weakness, and inefficiency (Rajabi & Ghaffari, 2008) .
It should also be noted that the family is the most fundamental social organization and is the main social component. Achieving a healthy community depends on the health of the family and the realization of a healthy family, provided that they have mental health and have a good relationship with each other (Karami et al., 2012) . Various factors are involved in this case one of which is strategies for coping with stress. Stress means pressure and force, and any stimulus that creates tension in humans is called stressor (Sharif & Yousefi, 2015) . Lazarus and Folkman (1984) defined coping strategies as a set of behavioral and cognitive responses aimed at minimizing tension stresses. Initial adaptations to the coping process differentiate the three main styles: problem-focused coping style, the direct feature of which is to reduce stress or increase stress management skills; avoidant-focused coping style that is characterized by avoiding exposure to the stressor and coping styles. The emotional-focused feature is the cognitive strategies that delay or eliminate the stressor by giving new names and meanings (Besharat et al., 2008) . In contrast to different coping responses, people give rise to different coping responses in the face of stressful situations, the characteristics and characteristics of the situation, especially the stressor’s controllability (Sharif & Yousefi, 2015) . Therefore, the use of various effective coping methods (problem-focused) and inefficiency (emotional-focused) have different consequences on physical and mental health of individuals (Sarafino, 2002) .
Studies have shown that conflicted relationships lead to problems in physical and mental health. In addition, there is a relationship between marital problems, marital conflicts, marital adjustment and depression symptoms (Beach et al., 1998; Soudani et al., 2009) . Conflict in human relationships is inevitable (Shahverdi et al., 2015) and disagreement in any marital relationship is natural. Studies have shown that there is not much conflict between couples who can manage conflicts in a positive way and have the ability to solve them (Siffert & Schwarz, 2010) . However, most individuals psychologically experience conflict infinitely stressful (Halford, 2001) . It is related to dissatisfaction and incompatibility, which means that increasing conflict in couples increases the incompatibility and dissatisfaction. In addition, these problems are considered to be divorce and separation grounds (Soudani et al., 2009) , and the relationship between marital conflict and marital satisfaction has a long history of research (Claire, Dush, & Taylor, 2011) . Typically, disturbed couples exhibit less communication skills than non-disturbed couples, and do not have a good view of their relationship. These couples are more likely to avoid each other than to solve it through negotiation (Carr, 2000) . In addition, the conflict between family members is harmful to the unity and integrity of the family and is associated with psychological problems such as depression and anxiety (Shahverdi et al., 2015) ; therefore, it is an important predictor of health (Troxel, 2006) .
On the other hand, the happiness of the community is one of the most influential factors in economic, cultural, social and political development, reducing family disputes and divorce and increasing the amount of desire and willingness to study, conflict in work and production. Therefore, the happiness and identification of factors associated with happiness are very important. This issue has always been considered by scholars in recent years and since it is possible to regard happiness as a cultural-dependent variable, its study in each society can be of special importance (Grossifarshi et al., 2006) .
Stress and life crisis are threats to physical and mental health that are inevitable in everyday life, but how to deal with them is important. Recent researches in this field have shown that the type of coping strategies used by the individual not only affects psychological well-being but also affects the physical well-being (Pico, 2001) . Incorrect coping strategies lead to an increase in the burden of stress and its consequences, and suffering from these symptoms is a combination of mental and emotional disorders (AghaYousefi, 2011) . Therefore, coping strategies are one of the variables widely discussed in the framework of the psychology of health (Sharif & Yousefi, 2015) .
Generally, given the fact that a healthy family usually handles healthy people and an unhealthy family will cause many problems at the community level, social problems will increase day by day if efforts are not done to improve the family (Satir, 1967) . Therefore, considering the importance of the subject and considering the theoretical foundations and the importance of strategies for coping with stress, sexual disfunction and mental happiness in marital conflicts and the lack of research felt in this regard within the country. Therefore, the present study seeks to find out strategies for coping with stress, sexual disfunction, and mental happiness in two groups of normal married women and women with different marital conflicts. Accordingly, the research hypothesis is:
There is a significant difference between strategies for coping with stress, sexual disfunction, and mental happiness in both married women and women with marital conflicts.
In order to confirm this hypothesis, ordinary married women and women with marital conflicts who referred to Yazd counseling centers in the years 1969-96 were examined. About 75 normal married women and 75 women with marital conflicts were selected. They completed the Lazarus and Fulkman (1985), Female Sexual Function Index (ROS) (2000), Panas Mental Happiness (1988) questionnaires (see Appendixes 1-3). The findings showed that there is a difference between strategies for coping with stress, sexual disfunction, and mental happiness in both married women and women with marital conflicts.
2. Materials and Methods
This research is causal-comparative in terms of its implementation, and the method of this research is descriptive because of the lack of manipulation on the variables in this research. The population of this study was all normal married women and women with marital conflicts who referred to counseling centers in Yazd in 2016-2017. According to the consultation centers, if the number of marital conflicts referred to counseling centers in Yazd is 100, the sample size is about 75 from Cochran formula. Thus, the sample included 150 women (75 normal married women and 75 marital conflicts) referring to counseling centers in Yazd, which was obtained through available sampling. One of the criteria for choosing these people was to be consent to participate in the study. Some participants refused to continue to participate in the study for any reason were excluded from the sample. The following questionnaires were used to collect data:
The Ways of Coping Questionnaire (WCQ) by Lazarus and Folkman: this questionnaire is based on the Lazarus and Folkman (1986) theory of stress. In their view, our interpretation of our events is more important than events itself. They believe that individual perception is one of the situations that determine its severity. Accordingly, a questionnaire of 66 items was designed. Scoring the questionnaire of coping methods is done in two ways: raw and relative. The choice of which scoring method should be performed depends on the information that the researcher seeks to do (Rostami et al., 2013) . Raw scores describe the coping effort for each of the eight types of coping. While relative scores describe the proportion of the effort that has been made in each type of coping. In both methods, individuals scramble for each substance on a scale of Likert’s four variants, which shows the frequency of each strategy in this form. This test examines eight coping styles that are divided into two types of problem-focused and emotional-focused. Lazarus and Fulkman (1986) reported internal consistency of 0.66 to 0.79 for each of the coping styles. In this research, Rostami (2012) obtained a Cronbach alpha of 0.87.
Marital Conflict Questionnaire (R-MCQ): Marital Conflict Questionnaire is a 54-item questionnaire designed to measure marital conflicts based on the clinical experience of Sanaei et al. (2009) . Consultants and other clinicians can use this questionnaire to measure the marital conflicts. For each question, there are five options that are assigned to 1 to 5 points. The maximum total score of the questionnaire is 270 and at least 54. Cronbach’s alpha for the whole questionnaire was obtained on a 270-member group of 0.96. In addition, this questionnaire has a good reputation. In the test content analysis stage, no questions were eliminated after performing the preliminary tests and calculating the correlation of each question with the whole questionnaire and its scales, due to the correlation of the questions (Sanaei et al., 2009) . In this study, internal consistency (by Cronbach’s alpha method) for the total scale of this questionnaire was 0.98.
Panas Mental Happiness Questionnaire (PANAS): This questionnaire was first created by Watson et al. (1988) as the Positive Affection Scale and Negative Affection, which later became known as the Happiness Scale by adding a total satisfaction scale of life. Subjects on a 5-point scale from 1 (very low) to 5 (very high) show the feeling of each of the 10 negative emotional states and each of the 10 positive emotional states in general felt. Davari (2013) used the views of the supervisor professor and several experts working in this field to determine the validity and confirmation that the listed questions and items are suitable for measuring the desired goals. After collecting comments and reviewing the suggestions of these people and discussing the questionnaire, the questionnaire was formulated and its validity was confirmed. Bakhshipour and Dejkam (2005) in Iran confirmed the factor structure of the questionnaire and calculated its alpha coefficient for each subscale as much as 0.87.
3. Female’s Sexual Function Index (FSFI)
Females’ Sexual Performance Index is a measure used to measure female sexual function. This scale was developed by Rosen et al. (2000) and it is validated in a group of women with sexual anxiety disorder. The questionnaire, with 19 questions, assesses women’s sexual function in six areas: desire, Arousal stimulation, Lurication, orgasm, satisfaction, and sexual pain. The mentioned questionnaire has been used in many studies outside the country and it has shown a high degree of internal consistency and reliability. Studies have shown a significant difference between the scores of the patients and the control group in each of the six domains. Considering the high scores and due to the shortness of the questionnaire, it seems that the female sexual function index is an appropriate tool for measuring sexual performance. Cronbach’s alpha coefficient of sexual performance index has been reported in Besharat, Khajavi and Porkhaghan (2012) . In addition, the internal consistency of the female sexual function questionnaire was reported as much as 0.91 (Kraskian Mojmari, & Kib Elahi, 2014) .
Table 1 shows the descriptive indexes of variables. As the mean of groups shows, the average of problem-focused strategies and happiness in women without conflicts is more than conflicting women and the average of sexual quality in women with conflict is lower.
In order to investigate the research hypothesis, initially the hypotheses of variance analysis are evaluated. The first is to check whether the data is normal. To test the normal distribution of scores in pre-test and post-test, Shapiro-Wilk test was used (Table 2).
Usually, if the significance level in the Shapiro-Wilk test is more than 0.05, then data can be assumed with high normal confidence; Levin’s test was used to examine the homogeneity assumption of variances. The results of this test are as follows (Table 3).
After confirmation of the hypotheses, one-way ANOVA was used to investigate the research hypothesis. The results of table number show that the F value of emotional-focused, sexual disfunction, and happiness is significant. Therefore, there is a significant difference between emotional-focused, sexual disfunction, and happiness in both married women and women with marital conflicts.
According to Table 4, there is a significant difference between strategies for coping with stress, sexual disfunction, and happiness in both groups of normal married women and women with marital conflicts.
The present study aimed to compare the strategies of coping with stress, sexual

disfunction, and mental happiness in two groups of normal married women and women with marital conflicts. According to Table 4, there is a significant difference between strategies for coping with stress, sexual disfunction, and mental happiness in both normal married women and women with marital conflicts. The results of this research are indirectly corresponded with Navabinejad et al. (2009) , Bagheri et al. (2010) , Alipour et al. (2010) , Amirimajd and Zarimoghadam (2010) , AliAkbariDehkordi (2010) , Sheikholeslami et al. (2011) , Shirazi et al. (2015) , Karimi et al. (2016) , Sepehrian Azar et al. (2016) . In explaining these results, it can be argued that Lazarus and Folkman (1984) defined coping strategies as a set of behavioral and cognitive responses aimed at minimizing stress-strain situations. The excitement and physiological excitement caused by tension situations is very unpleasant, and this suffering induces a person to relieve it. The emotional-focused coping is a style, in which the individual focuses on himself and does his best to reduce unpleasant feelings, such as anger and upset, mental activity, loneliness, and depression and the problem-focused coping style refers to behaviors that are used to solve a problem, rebuilding the problem cognitively or attempting to change the stressor position. Problem-focused behaviors include searching for more information about the problem and prioritizing and sorting steps for problem solving.
In this study, there was a significant difference between the emotional-focused strategies in the two groups of normal married women and women with marital conflicts According to the second finding, emotional-focused strategies were more controversial in the group of women with conflict. As HosseiniSedeh and FathiAshtiani (2011) state that women who have marital conflicts are more likely to use emotional strategies than emotional coping strategies, which claims Confrontation, avoidance, escape-avoidance, and self-restraint are more controversial in women. In explaining this finding, it can be said that marital conflicts in married women are due to the heterogeneity of the husband and wife in the type of needs and their method of satisfaction, elf-regulation, disputes, behavioral schemas, and irresponsible behavior towards marital relationships and marriage. The conflict process is created when one of the parties perceives the relationship. The other party opposes some of his\her favorite issues. Therefore, the conflict occurs when something provides satisfaction to the person, while the same thing leads to deprivation for the other one. Therefore, these individuals offer aggressive attempts to change the position and extent of hostility and danger, and try to regulate the emotions and actions of the individual, so that women with marital conflicts use the emotional-focused strategies more.
In the following explanation, which shows that women without marital conflicts use problem-focused coping styles, which are seeking social support, accountability, planned problem-solving and positive re-evaluation, it can be said that according to the results of those who do not have conflicts in marital life and live in peace prefer to use problem-focused strategies and accept their role in the problem and always strive to put everything in the right place. These married women make thoughtful thought-provoking efforts to change their position and create a positive meaning by focusing on personal growth.
The next results showed that women with marital conflicts have more sexual disfunction and women without any conflict experience better sexual quality. Sexuality is an important element of women’s general psychological well-being. According to Vermillion and Holmes (1997) , sexual disfunction is not merely personal and interpersonal stress but also associated with medical illnesses and psychosocial problems of women who are significantly affecting their health. Women’s sexual problems are the result of several factors that can affect their mental well-being and their health, including those that affect the person’s sexual desire, arousal and ability to reach orgasm. In addition, these types of problems lead to pain during sexual intercourse.
Disfunction is widely defined as the inability to fully enjoy sexual intercourse. Specifically, sexual disfunctions are the disorders that interfere with a complete sexual response. These disorders create problems for enjoyment or sexual intercourse, causing psychological injuries, depression, anxiety, and feeling of weakness and inefficiency. Therefore, women with marital conflicts more experience sexual disfunctions such as disturbance in desire, arousal, orgasmic disorders, and pain disorders.
In the case of mental happiness, there was a significant difference between the two groups of normal married women and women with marital conflicts. According to Lyubomirsky (2001) , happiness is defined based on direct ratings of individuals for their level of happiness, the amount of positive and negative long-term emotions, or the level of satisfaction with life. Mental happiness involves the emotional element (in other words, the experience of almost positive emotional affairs and almost negative emotions) and the cognitive element (in other words, life satisfaction or overall assessment of personal life). Therefore, a happy person is one who has many positive emotions, low negative emotions and experiences a lot of life satisfaction.
Variables such as parenting methods, recreational activities, marriage, divorce, serious disabilities, various personality traits, etc. are all factors that have been investigated by researchers in various researches as factors affecting happiness. In general, it can be concluded that happiness is a hypothetical instrument that is primarily involved in a set of external factors and variables, and secondly, internal variables such as cognitive factors (how to change and explain the individual of events) play an essential role in happiness. Therefore, married women without conflict increase their interest, cheerfulness, enthusiasm and pride, because the family without conflict is the focal point for security and tranquility, the marriage and comfort of man and woman, and people seeking to have a happy life in their family.
The main limitation of this research was the lack of cooperation between counseling centers and the researcher. Another limitation of the study is the use of subjective indicators with less objectivity to assess the variables of research (strategies for coping with stress, sexual disfunction, and mental happiness). If it was possible to assess these indicators, for example, by examining the participants’ behavior or getting a report from people in close contact with them, such as their family members, it would naturally have the potential to deliver significant results.
According to the findings of this study, it is suggested that semi-experimental research and the impact of new approaches on reducing marital conflicts and other family-related variables, such as attachment and structural characteristics of the family, and so on in married women with and without conflicts should be examined and solutions should be adopted to reduce problems. The use of research findings by counselors and psychologists in counseling centers and the use of research results as premarital workshops are also a practical application of this research.
