According to the report of the international health organization, depression disorder is one of the main causes of people’s disability. This organization also predicted that by 2020, this disorder would become the second main disease in respect of human and economic damages (
1). Depression and anxiety have a lot of convergences and coverings; and they follow a similar future in affected people. On the other hand, both disorders develop after some prolonged chronic stresses. Three-faced model of stress, anxiety, and depression has been confirmed in many studies (

4). Stress or mental pressure is an undesirable psychological and physiological mood generated in the reaction to unwilling motives (
5). A number of conducted studies on pathology and the criminal’s life history have shown that the crime and delinquency increases in psychological disorders (
6). Surveying the mental disorders in the Iranian penitentiaries has unwilling motives (
5). A number of studies on the pathology and the criminal’s history have shown that crime and offense increase in psychological disorders (
6). Related results to mental disorders in the Iranian prisoners have shown that 75% of the under-survey population is affected by mental disorders, 2.32% by personality disorders (
7) 78% by drug abuse, and 7.48% by mood disorders (
8). The life style of such people involves greater exposure to harmful events, compared to the rest of the society (
9,
10). One of the ways to deal with accidents and damages is spirituality. It includes a uniting energy connecting all of his individual dimensions through which, the person experiences life. Matthews and Clark (
11) have suggested piety as one of the spirituality dimensions. Piety is a personal way to express spirituality through one’s own beliefs in oneself and others, and also participation in ceremonies, rituals and practices showing religion. Numerous researches in different countries have shown that people who have spiritual beliefs and perform religious practices have higher mental health and are more adaptable as compared to those who have no such beliefs (
12) and receive lower scores in indices including depression, anxiety, psychological distress and damage (
13). Such beliefs help people reduce their emotional stress symptoms after an incident (
14). Personal beliefs and spirituality assist a person to cope and manage problems and give meaning to life. In addition, spirituality has been an accepted subject in cultures of contemporary societies and has widely been involved in the protection domain (
15,
16). Having belief in a super power and positive beliefs about oneself and others can influence the reduction of the amount of stress and improve their physical and mental health (
17). Through providing social support networks, hope, esteem, and emotional and mental relaxation, spirituality also helps better adaptability when encountered by stress (
18), and higher spirituality is accompanied with reduced depression symptoms (
19,
20). Khamis (
21) showed that having beliefs regarding spirituality and a super power was related to a low stress score after the incident in Gaza. Spiritual beliefs are accompanied with relaxation about mental stresses and having a method for happier meaningful life. Abdel-Khalek (
22) revealed that religious beliefs and spirituality had a positive relationship with quality of life. Moreover, spirituality was negatively related to all general health sub-scales. According to the conducted studies on Islamic religious beliefs, Khodapanahi et al. (
23) found that a significant positive relationship was present between religious orientation and adaptability; and also Pourghane et al. (
24) demonstrated that there was a negative relationship between stress level and religious beliefs. To analyze the role of religious and spiritual values in stress, it was revealed that people, who have stress symptoms, are on the low or middle level in respect to spiritual beliefs, and the anxiety score of people with low-level spirituality is higher than those with high-level of spirituality (
25). The obtained results from different studies emphasize spirituality effectiveness in health. Moreover, penitentiaries are vulnerable individuals in every society; greater involvement in dangerous behaviors is a characteristic of these individuals, and one contributing factor to such behavior is drug abuse that causes mental diseases and discomfort (
26); A considerable population of penitentiaries have symptoms of depression and anxiety, and stress and mental pressure plays a significant role in their routine life. Recognition and practice of methods that protect them from chronic harms such as depression, stress, and other mental disorders is essential, while therapeutic methods seem to be urgent if they have already developed such disorders.
