AI Chatbots Often Fail To Help Users in Mental-Health Crisis

According to new research conducted by Scale AI and shared exclusively with TIME, chatbots are adept at discerning when a user is in crisis, but often fail to provide adequate help.

In about 35% of test conversations in the study, different AI chatbots recognized the user was distressed but didn’t refer them to helpful resources, such as a suicide hotline, according to the research.

“The models do a good job—regardless of the scenario—of identifying, ‘Look, this person's talking about something harmful,’” says Patrick Oathout, Red Team & Safety Lead at Scale AI.

“But they'll respond in a very just empathetic, kind way as opposed to saying, ‘Okay, it's time that we get you help.’” The models performed worse at responding to users’ distress when they were engaging in long, multi-turn conversations—a deficit that matches the findings of previous studies, Oathout adds.

To test AI models’ effectiveness at responding to distressed users, Scale AI asked 19 licensed clinicians and crisis counselors to write 718 realistic chats, simulating scenarios where someone in crisis reaches out to a chatbot.

The company tested 25 frontier models, including those from OpenAI, Anthropic, and Google.

It graded the models’ responses based on a rubric that included whether it was compassionate, de-escalated the situation, and steered users to an expert who could help them, said Oathout.

It also assessed whether they refrained from moralizing, such as criticizing suicide, and disclosed it wasn't a therapist.

Based on the research, Scale AI research developed DistressBench , a new benchmark designed to evaluate how well models reply when someone tells them they're thinking about committing suicide or self-harm.

How chatbots respond to mentally distressed users is a question with high stakes.

More than half a million people in the U.S. died by suicide between 2014 and 2024, with 2022 marking a record high, according to the health-policy organization KFF.

According to the CDC , an estimated 14.3 million people seriously thought about suicide in 2024.

Increasingly, vulnerable people turn to chatbots for comfort, companionship, or guidance when dealing with mental-health distress.
