Addiction is a chronic and relapsing disease that several genetic, mental, social and environmental factors in interaction with each other lead to the initiation and continuation of it. Like other mental illnesses, addiction is rooted in several factors that each person may have special group of confounding factors and if only one of those factors considered in addiction treatment and other factors were not be not focused assuming the positive effects of that factor, other parameters can reduce effect of that factor (Whashton, 2007). Therefore, current methods of treatment don't have adequate efficacy and even in the best treatments success rates in yearlong have been reported 30-50% (Brien & McLellan, 2006). All factors are considered essential in treatment. Addicted people as vulnerable communities face to psychological emotional, social and economic problems that have negative impacts on their quality of life and sexual self-efficacy that keeps out them from daily activities (Chen, Yeh & Lee, 2009; Elliot et al, 2006). National Institutes of Health has defined erection malfunctions as inability to make or maintain an erection sufficient penis (as satisfactory sexual activity) and this disorder can be progressive (National Institute of Health, 1993). This is the most common sexual dysfunction among men. More than 30 million men in North America and more than 150 million men worldwide have been reported some form of this disorder (Aytac, MacKinlay and Krane, 2003). The main cause of undersexed in men was not enough pressure in sexual organs system, physical factors and psychological factors. The physical factors include cardiovascular disease, diabetes, nervous system disorders, hormonal problems, surgeries, strokes, chronic medical conditions, lifestyle inactive and excessive consumption of alcohol and smoking. Psychological factors include low self-esteem, stress, depression and communication problems (Miller, 2000; Lue, 2004; Melman and Gingell, 1999; National Institute of health, 1993). Dysfunctional erections can emotionally and physically affect the self-image of a man's self-image and his relationship with partner. Dysfunctional erections can be associated with some social -psychological issues, such as depression, anxiety about sexual performance, denial of sign, refusing sex, relationship distress and disruption in life (Feldman, Goldstein and Hatzichristou, 2005). Similarly, quality of life is related to health and its individuals' subjective assessment about their current health status, medical care (Liu, 2006). Regarding the importance of family and avoidance of splintering it, understanding factors associated with sexual self-efficacy are essential for stability of family life. It is expected by increasing sexual self-efficacy in couples, especially addicts, mental, emotional and social problems would be reduced. Also, by upgrading level of sexual self-efficacy and satisfaction of life, people will pay to the social, cultural and economic progress with more peace of mind (Sanaii, Alaghband and Hooman, 2000). Researchers such as Carroll, Ebener &Gawin (2009), Mandel, Edelen,Wenze, Dahl & Rounsaville (2008) know training strategies are effective to improve physical and mental health of addicts. However, researchers show that training interventions can be effective in addicted people to enhance quality of life and increase their performance of immune system and hopefulness in them (De Leon, 2006). One appropriate method of intervention groups is based on quality of life. Quality of life therapy is based on a new approach that was founded by Frisch (2006) and includes integration of positive psychology and cognitive therapy. It is associated with the latest Beck's conformation of cognitive therapy, cognitive theory of depression and mental pathology. Quality of life therapy involves an approach to increase satisfaction of life. Satisfaction of life can be described as individual assessment of various aspects (Frisch, 2005). …
