one of the factor associated with marital satisfaction is intimacy . to promote the intimate emotional bond among family members , interaction and communication with a true mutual understanding another factor associated with marital satisfaction is the role of the media , and in particular , satellites . not only can satellites directly affect all members of the society it also has an important impact on institutions such as the family . metani et al . in 2013 concluded that people of all ages spent an average of 3 h per day watching satellite networks . moreover , it can lead to increased individualism and reduced collectivism ; this issue has been considered to be a factor that can damage family cohesion . numerous studies have been conducted on this media ( satellite ) , some of which will be mentioned in this study . however , the amount of use and the type of satellite channels can not be ignored . in regards to the relationship between satellite channel use and family relations , studies have shown that families who did not use satellite networks compared to families who used satellite networks had significantly better family relations . in general , families who do not use satellite networks have a stronger family structure compared to families who do . in another study , an inverse relationship was observed between the use of satellite networks and family structures . in line with this subject , it should be noted that , according to family counseling specialists and experts , satellite networks have an important role in the analysis of factors that cause changes in the institution of family in the age of communication . satellites have made possible the experiencing of intercultural relations with minimum expenses , which has facilitated the increasing use of this media . however , this media has in fact increased the contradictions in human relations and has reduced face - to - face interactions and understanding among individuals . given the importance of the family and the factors affecting spousal relations and the use of satellites by the majority of families as a way to spend family leisure time , pathological studies must be conducted on satellite networks effects on factors influencing spousal relations ( marital satisfaction and intimacy ) . nevertheless , no studies were found in this regard in the field of medical sciences , especially community health nursing . there were few studies on the relationship between watching satellite channels and marital satisfaction and marital intimacy . therefore , the researcher conducted this study with the aim of investigating the relationship between watching satellite channels and intimacy and marital satisfaction in isfahan , iran , in 2014 . this cross -

viewers of satellite . moreover , the duration of interaction had a significant relationship with intimacy and marital satisfaction ( p < 0.050 ) [ table 2 ] . the correlation coefficient between marital satisfaction , intimacy , and duration of interaction of couples living in isfahan in 2014 in the present study , a significant difference was observed between the mean scores of marital satisfaction and intimacy and the duration of the couples interaction among the two groups of viewers and nonviewers of satellite networks . this study showed that watching satellite channels reduced the intimacy and marital satisfaction of the couples and duration of interaction among the couples . the findings of some studies were in agreement with that of the present study including the study by shakerinia . in his study in rasht , shakerinia indicated that satellite viewers have weaker social capital , low life satisfaction , and undesirable mental health . furthermore , sharievska suggested that people with low marital satisfaction are drawn to the use of social networks and experience their positive and negative effects . 2013 in a comparative study entitled trust , community , and gender studied mutual trust between the two genders and explained that media , both in terms of access and use , has a significant relationship with mutual trust . the fundamental point is that the greater the access to the media , the more the mutual trust between people is reduced . it can be assumed that access to and use of media can reduce mutual trust between people through analyzing different life aspects and relationships and illustration of its negative aspects and occupying leisure time and replacing people 's relationships with media . other comparative studies can be noted regarding the relationship between intimacy and marital satisfaction of the two groups . in a longitudinal study , researchers concluded that insincerity among young couples was the predictor of divorce during middle - age years . one of the causes of divorce is low marital satisfaction , and these two components ( intimacy and marital satisfaction ) can be linked to each other . a similar study showed that the more the couples interacted the less time they spent watching satellite channels . people who experience this intimate relationship through using online social networks attempt to maintain and even increase this connection . interacting with media prevents the interaction of the family and reduces mean interaction among family members . in a similar study , it was observed that marital satisfaction , especially for women , was associated with the consulting of spouses with one another . the studies of amato et al . and johnson and anderson showed that the more time people spend with each other and interact with each other the higher their marital satisfaction will be . this was a descriptive analytical study and it could show the relationship between the variables , however , it could not determine their effectiveness . there were also problems related to the high volume of samples and establishing mutual trust and feelings of security among the participants . the researcher tried to provide comprehensive information about the study and the participants results in order to create a sense of mutual trust . its impact could not be ignored during the completion of the questionnaire . in general , the results of this study and previous researches have established the need for education regarding the positive and negative consequences of satellite programs . this study showed that the mean scores of intimacy , marital satisfaction , and duration of interaction were higher in the group of nonviewers of satellite networks compared to the group of viewers . watching satellite programs
