Background and Objective: Many contemporary Western scientists are emphasizing that the problem with modern humans is that they are basically in need of faith and spiritual values because faith in God is associated with a spiritual power that helps humans to endure hardships and in turn diminishes anxiety level. Saying prayers is assumed as a palliative treatment and a stimulus to biological and physiological responses in patients. Therefore, the initial purpose of this study was to explore and explain the role of spiritual beliefs and religious practice in improvement of mental health and decreasing mental disorders. Materials and Methods: Content analysis and library information search were used to collect the data for this study. In addition, this research was an endeavor to throw light upon, analyze and explain Islamic teachings, concepts and themes as related to mental health and mental disorders. Results: Analytical results of several studies indicate that there is a significant relationship between depression and religious beliefs (P<0.05). As reported by the previous studies, there is an inverse relationship between religious beliefs and spouse abuse. Conclusion: Our results demonstrate that there is a significant relationship between religious beliefs and mental health and people with well-built faith have more mental peace. Meanwhile, adherence to Islamic practice has a preventive and diminishing role in mental disorders such as anxiety, depression, sexual perversions, suicide and spouse abuse.

Background and Objective: Given the growing rate of psychiatric disorders, especially in young populations, detailed data on frequency of these disorders for further national public health strategiesis of great importance.We aimed to survey the frequency of different psychiatric disorders among children and adolescents in Kohgiloyeh and Boyer-Ahmad province.
Materials and Methods: 1001 cases were selected using the random cluster sampling method and all cases were interviewed by expert psychologists using a Persian version of semi- structured K-SADS-PL questionnaire. Data were then statistically analyzed by SPSS software.
Results: 20.5% (205 out of 1001) of studied cases showed at least one psychiatric disorder and 79.5 % showed no sign of any disorders. Anxiety disorders were the most frequent disorders  (15.5%) followed by the behavioral disorders (7%), smoking and drug abuse (6%), behavioral disorders (2.4%) and neurodevelopmental disorders (2%), but no case was observed with psychosis.
Conclusion: in comparison with other studies from Iran or other countries the prevalence of psychiatric disorders in Kohgiloyeh and Boyer-Ahmad is relatively high and special policies and efforts are suggested for enhancement of mental health values in this region.
