The question is no longer whether young people are using AI for mental health care, but the soundness of the advice they receive, health officials say.

A recent survey showed that the use of AI chatbots for mental health care among adolescents and young adults increased by 60% in just a year, a trend that survey organizers said is likely to continue.

Hao Yu, an associate professor of population medicine at Harvard Medical School and the Harvard Pilgrim Health Care Institute, led the study, which had 1,727 participants.

In this edited conversation, Yu said AI may help fill a treatment gap left by a rising problem among young people in the U.S. amid a shortage of mental health professionals. Yu said the focus should now turn to ensuring the counsel being offered is helpful and not harmful.

Gazette: What did your survey find?

Yu: We did a similar study last year, and at that time, we found one in eight young people between the ages of 12 and 21 used AI for mental health problems. This year, we found an even higher proportion, almost one in five. That means nearly 20% of young people in this country are using AI for mental health advice. That's a rapid increase in one year.

Not surprisingly, we found variation in AI use across youth groups, with older youth more likely to be using AI and young women more likely to use AI for mental health issues.

It may surprise some that we found the majority of youth using AI did not disclose their use to any adults, either parents or physicians. That might be concerning because misinformation is available through different AI models, which are not designed to provide mental health advice.

So, we would encourage parents and physicians to talk with their children about their potential use of AI. They may be able to identify whether their child has a mental health issue or help their child distinguish between accurate information and the misinformation we know is available online.

What does this tell us about the state of young adult and adolescent mental health care today?

This definitely shows that there's a big issue facing the U.S. today. On one side, we have a rapid adoption of AI across different parts of our society. On the other, there is an increased prevalence of mental health issues among young people. Putting these two together makes it not so surprising when we see that youth are increasingly turning to AI for mental health advice.

Does it also highlight that there's not enough capacity in our mental health care system?

Our health care system has an acute shortage of psychiatrists, especially child psychiatrists, and only half of those with mental health needs actually receive mental health treatment.

So, if a youth has mental health issues, AI offers some advantages. AI is patient. AI is available at any time, 24/7. You don't need an appointment to talk with AI, and AI is nice. It's rare for AI to be harsh or become impatient. So there are advantages, especially for people living in rural or remote areas with severe mental health workforce shortages.

How much do we know about the quality of the responses that come from these general-use AI chatbots? Is it still a concern that kids and young adults may get bad, even harmful advice?

That's still a concern. And it's true that tragedies like suicide attempts have happened when youth talked with AI about mental health issues. AI companies promised they would install guardrails, but there's a lack of empirical evidence about how those promises are being kept.

Beyond this specific study, many researchers are interested in assessing the safety and efficacy of mental health advice offered by AI. More people are paying attention, so we hope there will be some improvement, but that remains to be seen.

The paper mentions that these AI models are designed to be friendly, agreeable and flattering. Might kids also be getting information that is reinforcing in a positive, but still unhelpful, way?

Most AI models try to be appealing and flattering as a way to keep their customers, and many people, especially youth, are easily hooked. But it's still a concern whether the advice and information provided by AI are useful.

In our study, we found that the vast majority of youth, more than 90%, say the advice is useful, but that's still an empirical question we need to assess: Is AI-provided mental health advice really helpful and accurate?

The safety and efficacy of AI models are a priority for research because, as we said at the beginning, these things are already happening, and the trend among youth is increasing. As a society, we have the responsibility to make sure that what they are receiving is accurate and helpful.

You mentioned that there are AI chatbots that are designed to be therapeutic. I've seen earlier studies that show that they can be very good, but their development has been slow. Is a key message that we need to accelerate the development of these therapeutically trained bots?

Yes. We have an acute shortage of child psychiatrists who can meet unmet needs among our youth, so we want AI models that can mitigate the shortage. It's not surprising, though, to see people concerned about the potential quality and safety implications of even specifically trained, mental health–oriented AI.

That's why some policymakers, as in Illinois, have taken action. Ultimately, this is an issue of patient safety.

Where do you see this trend going? We've seen an increase from one in eight adolescents and young adults using AI for mental health needs to one in five. Are you planning on doing the survey next year, and do you expect it to be an even greater percentage?

We definitely will have follow-up surveys, and we will most likely see an increase. It's not surprising given that AI is now part of daily life for youth and that there are unmet mental health needs. AI is readily available and endlessly patient.

Were there any surprises in this for you?

One surprise is that we didn't find a significant difference between rural and metropolitan areas, even though we know that a rural-urban digital divide exists and that rural and remote areas have a severe shortage of child psychiatrists.

If future research confirms that rural and urban kids are equally likely to use AI, that might help reduce the adverse effects of a workforce shortage in rural areas. AI has that potential for sure. But we want to make sure these specific AI models meet clinical standards for mental health advice.
