Terms and Definitions

Suicide is the act of causing one's own death, often as a result of despair or mental health problems including depression, bipolar disorder, schizophrenia, substance abuse, or feelings of loneliness or isolation.

The suicide rate is a statistical measure that reflects the number of suicides that occur in a specific population during a specific time period, usually per 100,000 people per year. It is a crucial index to understand the severity of suicidal problems within any population.

Suicide prevention encompasses various collective measures and initiatives undertaken by health professionals, social workers, government, non-government organizations, and society as a whole to reduce the incidence of suicide. These measures may include mental health awareness campaigns, support hotlines, and therapeutic interventions.

Mental health refers to a person's condition regarding their psychological, emotional, and social well-being. Mental health affects how people think, feel, and act; it also helps determine how they handle stress, relate to others, and make choices. Mental illnesses can negatively affect an individual's mental health, potentially leading to suicidal thoughts.

Stigma refers to a mark of disgrace associated with a particular circumstance, quality, or person. In the context of suicide, stigma can be a barrier that prevents individuals from seeking help when struggling with mental health issues or suicidal thoughts. This can significantly impact suicide rates and the effectiveness of prevention efforts.

Social Isolation is a state characterized by a lack of contact or meaningful relationships with other people. This state can contribute to feelings of loneliness, increased stress, and reduced mental health, which can potentially lead an individual to consider or commit suicide.
