Mental health and artificial intelligence are two of the most prominent conversations in recent years. For World Mental Health Day, Statista asked adults in the United States, the United Kingdom, and Germany how they are already engaging with AI for their mental well-being: who is using it, what for, how often, and whether it actually helps.
The numbers are striking. More than half of adults in all three markets—57% in the U.S., 56% in the UK, and 57% in Germany—already use AI tools for mental well-being. That consistency across three major developed markets is one of the more remarkable findings: whatever is driving people toward AI for personal support, it appears to transcend national context. Mental health itself ranks among the top personal challenges cited across all three markets, named by roughly one in four adults. The two facts together set the scene for what follows.
