The Impact of Negative Moral Character on Health and the Role of Spirituality: A Narrative Literature Review

Although negative moral character is highly prevalent, it is not included in the International Classification of Diseases (ICD). Along with the modification of WHO ICD-11, spirituality should be acknowledged for its potetnial role in the prevention of negative moral traits. This study aimed to explore the effects of negative moral character on health and determine the role of spirituality in improving negative moral traits. This narrative literature review was conducted from 2020 to 2023 in Kabul, Afghanistan. The articles were obtained from the Web of Science, PubMed, and Google Scholar databases. As demonstrated in this narrative literature review, most of the relevant experimental and observational studies have found that negative moral character can have significant negative impact on overall health and well-being. Many studies have established the positive role of spirituality in improving negative moral character. These studies concluded that facilities must be available within schools, universities, and communities for everyone to gain knowledge of spirituality and improve their negative moral character. Considering the adverse impacts of negative moral character on health, the current study proposes the addition of moral disorder to the WHO International Classification of Diseases. According to this literature review, spirituality will improve negative moral character and strengthen excellent moral traits.
