What does the term 'suicidal ideation' refer to?

The term 'suicidal ideation' specifically refers to thoughts about wanting to end one's life or commit suicide. This includes any contemplation or consideration of self-harm with the intent of ending one's life. It is important to recognize that this concept encompasses a range of thoughts, from fleeting considerations to more serious and persistent thoughts about suicide. Understanding this definition is crucial for suicide risk assessment, as recognizing and addressing suicidal ideation can be a pivotal first step in intervention and prevention strategies.

The other options refer to different aspects of suicidal behavior and risk. Feelings of hopelessness without intent, while serious, do not encompass the active thought of wanting to end one's life. Planning a method for suicide indicates a higher level of risk and intent beyond just ideation, and having made a prior suicide attempt reflects a history of severe suicidal behavior, which is also distinct from the initial stage of having thoughts about suicide.
