Which of the following is considered a warning sign for suicide risk?

Threatening self-harm or suicide is a significant warning sign for suicide risk. This behavior indicates that an individual may be experiencing profound emotional distress, and it can serve as a direct indication of their intention or contemplation of ending their life. Verbalizing thoughts about self-harm or suicide is a serious concern and suggests that the person is in a dangerous mental state requiring immediate attention and intervention.

The other options, such as writing about positive life events, making future plans, or seeking out social activities, typically suggest engagement with life and may indicate a person is feeling better or considering future perspectives. These behaviors are generally not associated with an increased risk of suicide and may even reflect healthful coping or recovery efforts. In contrast, threats of self-harm directly signal a need for urgent support and should be treated with serious consideration.
