Which of the following types of suicide is characterized as planned and intentional?

The characteristic of planned and intentional action aligns with the definition of deliberate suicide. In this type, individuals typically go through a thoughtful process, often contemplating their situation and outcomes, leading to the conclusion that taking their life is their desired resolution. Such individuals may have made arrangements, contemplated methods, and even left notes, indicating a clear intent to end their lives. This contrasts with other types, which can lack the same level of planning and intent.

Spontaneous suicide refers to acts that occur without significant prior contemplation, representing more of an impulsive response to a specific trigger. Accidental suicide implies a lack of intent, often happening during risky behavior where the person does not wish to die but perhaps engages in dangerous activities. Impulsive suicide is characterized by sudden, unreflective actions, usually taken in moments of crisis, rather than through a premeditated process. Therefore, the defining features of planned and intentional actions distinctly classify deliberate suicide as the correct answer.
