Addiction is a biological, psychological, and social disease; several factors affect the etiology of drug abuse and addiction, whose interaction with one another can lead to the onset of drug abuse and ultimately addiction (
1). Clinical findings indicate that personality characteristics, life style, attitudes, beliefs, feelings, dependencies, emotions, and behaviors formed during an individuals’ growth play a key role in the formation of drug dependence (
2). Through providing a set of behaviors and a special lifestyle, religion, as a defensive shield, can protect people from harmful factors and environmental stressors (
3). In this regard, it seems that using the aid of internal and personal forces is an important factor in dealing with the temptation to relapse (
4). Allport believes that religious orientation can be intrinsic or extrinsic. In the intrinsic religious orientation, faith itself is considered as a transcendent value and a pervasive motivational commitment, and not a means to achieve the intended goals. However, in the extrinsic religious orientation, religion is something external used to satisfy people’s individual needs such as achieving security and/or a position. People who have such an orientation apply religion as a means to achieve their objectives (
5). In ontology, religion is regarded as a spiritual coping strategy that plays an integral role in dealing with stressful events. In other words, a spiritual coping is an internal source which searches for meaning in times of stress, develops the intimacy with God, and aids people to perceive the meaning of life and to relax (
6). Perception of God, from a psychological perspective, is a cognitive-affective pattern that is shaped through a child’s first interactions with the important people and caregivers in his/her life, and it repeatedly renews throughout life, consistent with the person’s growth and mental maturity. This orientation model guides one’s behaviors and feelings towards God. This is why the perception of God is a coherent set of the latest level of one’s perception of abstract and metaphysical issues. In addition, people’s perception of God and their image of God play key roles when one wants to examine people’s mental traits through considering people’s perception and their mental structures (
7). The concept of God determines the transformation and formation of personal religion (
8). It seems that religion and the relationship with God impact people’s cognitive process. The faith and belief in God and the fact that everything starts very well when people trust in God and that God controls everything, create a sense of optimism and confidence in an individual’s future performance (
9). People consider God as an aid in crisis, which can be a bright light for the whys of religious coping theory (
10). The results of previous studies conducted on the effect of religion on decreasing distress and turmoil indicated its positive effect on compatibility, promoting mental health, and decreasing symptoms of various diseases and supported the existence of a positive correlation between religion and mental health. Several studies have shown that most people abusing drugs suffer from psychological problems including stress, anxiety, and depression. In other words, addicts apply drug abuse as an avoidant, negative, and inefficient coping strategy to reduce their problems (
11). Nonnemaker, McNeely, and Blum (
12), in a study, sought to distinguish public/extrinsic religion (attending religious communities and taking part in charities) from private/intrinsic religion (praying and paying attention to religion) and they found that these 2 forms of religion can protect people from using cigarettes, alcohol, and marijuana. Based on these results, while private religiosity was a more reliable preservative factor even against recreational drug abuse, public religiosity only had a negative correlation with continuous drug abuse. The results of Gartner et al. (
13), Marsiglia et al. (
14), Robinson et al. (
15), Wills et al. (
16) revealed that having religious attitudes and beliefs was related to reduction of psychological stress and prevention of risk behaviors such as smoking, drinking, and using drugs. Religiosity reduces the effects of the pressures of life on tendency towards drug abuse and it controls the increase in the level of drug abuse over time. In their studies, these researchers mentioned that addicts, compared to non-addicts, might have lower level trends in spiritual intelligence. Moreover, religious beliefs reinforce socially responsible behaviors, prevent misbehaviors, and are associated with lower levels of drug and alcohol abuse, early sexual activities, and delinquency (
17). Galanter et al. (
18) in a study entitled “Assessment of Spirituality and Its Relevance to Addiction Treatment” through conducting a comprehensive and informative review, concluded that religious orientation considerably overlaps with spiritual intelligence and it is one of the most important aspects of addiction and addiction treatment, which has been seriously neglected. Bradshaw et al. (
19) found that a positive mental image of God was negatively correlated with a wide range of behavioral symptoms including depression and anxiety. Kirkpatrick and Shaver (
20), in their study, demonstrated that people who had a secure attachment to God, compared to those who had ambivalent attachment to God, had higher life satisfaction and experienced lower anxiety, depression, and diseases. Moreover, the results of Ellison et al. (
21) showed that paying attention to religion and praying can decrease the detrimental effects of diseases and anxiety. Maton (
22), in a research report, indicated that spiritual support created due to the relationship with God decreased the effects of fundamental stressful situations and had significant positive impacts on depression and levels of adjustment and self-esteem. Studies have also shown that the quality of the image of God can affect the formation of self-concept and body image .7 In another study, Ai et al. (
23) demonstrated that patients who had stronger religious beliefs and applied more positive coping strategies such as forgiveness and search for a spiritual connection with God in their daily lives recovered more quickly and had a better mental health. People expect religion to convert their unsatisfactory condition into a missing optimal condition and remove the undesirability of the status quo. Religion aids people to deal with their difficulties easily. By accepting religion as an important factor playing a role in people’s lives, it can become a source of individuals’ behaviors and personality characteristics, and its impacts on moderating stress and mental and physical health can be examined. Professionals working in the field of mental health have paid little attention to the role of religion in preventing diseases and treating them. On the other hand, the acquisition and application of the concept of God in various human groups are of significant importance for most psychologists, researchers, and religious experts. Given the importance of the issue, the present study aimed at examining and comparing religious orientation and perception of God in addicts and non-addicts.
