Excessive AI Use Linked to Higher Depression and Anxiety, New U.S. Study Finds

A large-scale study in the United States has found that individuals who frequently use AI chatbots and other generative AI tools are more likely to exhibit symptoms of depression and anxiety. The research, published on January 21 in the prestigious medical journal JAMA Network Open, was conducted in collaboration with Massachusetts General Hospital and several other U.S. institutions.

Study Details
The study surveyed 20,847 U.S. adults via an online questionnaire conducted between April and May 2025. Participants were asked about their frequency of AI tool usage, including chatbots and generative AI platforms. Their mental health was assessed using the PHQ-9, a standard measure for depression.

Key Findings
Participants who used AI tools daily or frequently were found to display higher levels of mild to moderate depression. These individuals also reported symptoms such as anxiety, irritability, and mood fluctuations. However, researchers emphasized that the study does not establish a direct cause-and-effect relationship between AI use and mental health issues.

Why This Study Matters
This is the first large-scale study to scientifically examine the relationship between AI use and mental well-being. By including a substantial population sample, it provides important insights into how modern technology might influence mental health.

Implications
While AI tools make daily life more convenient, the study signals the need for balanced and mindful usage. Mental health symptoms should not be ignored, especially as AI becomes increasingly integrated into everyday routines. Experts recommend awareness and moderation to prevent potential negative effects on psychological well-being.
