Internet addiction is a new and attractive issue that has been recently considered as a behavior-based addiction. People with internet addiction who spend hours and days in social networks cannot disconnect this connection and are not interested in leaving their computers. While their real life activities and their social communications collapse and they become more dissociable (A, 2006). In this regard, Sanders (2000) reported the decrease in relationship with parents, seclusion from society among intemperate users. He believed that this issue leads to decrease in social support and contact among users and finally causes depression and solitude among them because a person during adolescence needs to share his/her emotions, excitement, doubts, and wishes (quoted by Ghaffari and Ahadi, 2007: 92). Today, the prevalence of internet addiction among adolescents can be discussed as a serious crisis in their individual and social life (B, 2010). The results of studies show that when various habits take a form of addiction affect on different parts of the life badly (Shepherad, 2005). In this regard, researches have shown that internet addiction has harmful effects on the most important responsibilities of students, namely education (Ranjbar et al., 2011). On the other hand, researches show that home is the first location in people life and it must be such that creates the spirit of peace and balance among their members. The existence of a warm, with spirit, and thriving environment in the family is a confident base for their members and guarantees mental health of people (Norouzi,2003). Attention to the family and attempt for problem solving of this organization can promise a valuable society(B, 2005. Family function is as one of the important indices guaranteeing life quality and mental health of the family and their members and can be as a key factor in creating flexibility and decreasing current and future risks related to unpleasant events and improper conditions (B, 2006). The results of Norouzi’s study (2003) report positive effects of behavior style of intimate, responder, and integrated families and negative effects of behavior style of apathetic, opinionated, disordered families on mental health of people.
