Life circumstances can influence one‘s mental health from birth. Individuals who experience positive circumstances are generally emotionally secure and successful in school and are able to establish healthy interpersonal relationships. Negative circumstances such as poverty, poor physical health, unemployment, abuse, neglect and unresolved childhood loss generally precipitate feelings of hopelessness, helplessness or worthlessness. Hence, a study to assess the knowledge of public was conducted by the researcher towards mental health disorders. The samples were selected though non-probability quota sampling and they were given a structured questionnaire related to mental health disorders. 100 samples were selected from five groups from the public. With regard to the knowledge, it could be seen that there was a significant difference in the mean knowledge scores between the public who are graduates and those who are secondary school educated.
