Introduction and objective:
A sense of coherence is a global human orientation that expresses the level to which a person possesses a piercing and enduring yet dynamic sense of certainty that the stimuli that occur during the course of life from the external and internal environment, are predictable, structured and explainable. Mental disorder is a term used to indicate the existence of a system of clinically-established behaviours or symptoms combined in most cases with suffering and impaired individual functioning. The aim of the study was to attempt to discover a relationship between the level of sense of coherence and mental disorders and stress, based on the available literature.

Review methods:
Available literature was analyzed based on the English-language databases PubMed, Scopus, ScienceDirect, Medline, among others, using the Google Scholar search engine. The analysis included 30 articles of the 1,140 retrieved by the above method. Publications no older than 14 years were used as search criteria using the following key words: sense of coherence, mental disorders, stress.

Brief description of the state of knowledge:
After analyzing the study, it was found that the level of sense of coherence affects the occurrence of stress and mental disorders. A higher level of sense of coherence is associated with a lower occurrence of mental disorders. When the level of sense of coherence is low, there is a higher risk of mental disorders. This relationship also applies to the level of feeling stressed.

Summary:
Numerous authors indicate that in people with mental disorders, the level of sense of coherence is lower than in people who have not been diagnosed with mental problems. The level of experiencing stress correlates with the level of sense of coherence.
