The purpose of the extant study was to explore the relationship between religiosity and suicidal ideation. Through this exploration, further knowledge was sought relevant to gaining better understanding regarding the higher suicide rate continuing to be experienced by young adults. Endeavoring to discover why the suicide rate continues to increase for the subject population, depression and anxiety emerged as major contributory risk factors. Although religiosity has been shown to be related to the reduced risk of suicidal behavior, the therapeutic value of religion relevant to suicide prevention and treatment has not been sufficiently recognized. Considering the enormity of the current suicide problem, pursuits relevant to discovering effective tools enabling impactful prevention and treatment strategies remain essential to reducing suicide deaths. The subject study was conducted utilizing a systematic literature review (SLR) incorporating both qualitative and quantitative data toward the goal of acquiring advanced knowledge based upon existing studies relevant to the subject matter under consideration. Religiosity has proven to be positively associated with reduced risk of suicidal ideation and suicidal behaviors, effectively serving as a possible protective influence for those of all ages plagued with suicidal thoughts. Further, depression and anxiety have been identified as two potential pathways leading to increased suicidal behavior. Contrarily, religiosity has emerged as an important protective factor associated with less depression and therefore, fewer instances of suicidal thoughts. The protective nature of religion has been shown to extend to young adults without regard to the presence of identified potential suicidal behavior pathways. In light of the complexities of suicide and linked factors, related studies have been undertaken across various disciplines. The social, mental health, religious, and psychological implications associated with the problem underscore the importance of the continuing pursuit of effective prevention and treatment strategies.
