Daily AI Use Linked to 30% Higher Depression Risk, Especially in Middle-Aged Adults

Daily AI Use Correlates with Higher Depression Rates

People who interact with AI chatbots daily face significantly elevated risks for mental health challenges, according to new research published in JAMA Network Open 1

1

. The study surveyed 20,847 US adults and found that daily AI use was associated with a 30% higher risk of at least moderate depression compared to non-users 2

2

. Among the participants, 10.3% reported using artificial intelligence at least daily, while 5.3% engaged with AI chatbots multiple times per day 1

.

Lead author Dr. Roy Perlis from Massachusetts General Hospital noted that of those with daily or greater AI use, 87.1% reported using it for personal reasons—including recommendations, advice, or emotional support—followed by 48% for work and 11.4% for school 3

. The research revealed a clear dose-response relationship: the more frequently someone used AI, the stronger their symptoms of depression and anxiety became 3

Middle-Aged Adults Show Particularly Strong Associations

The correlation between AI use and depressive symptoms proved especially pronounced among middle-aged adults. Those aged 45-64 years showed a 54% higher risk of depression, while adults aged 25-44 had a 32% higher risk . Interestingly, adults aged 65 years or older did not show the same elevated risk 1

. The study also found that men, younger adults, higher earners, those with higher education, and urban residents used AI more frequently 3

3

.

Using standardized measures including the nine-item Patient Health Questionnaire (PHQ-9), the two-item Generalized Anxiety Disorder (GAD-2) screen, and the Brief Irritability Test, researchers documented that greater AI use correlated with higher scores across all measures 1

. Notably, using AI for work or school wasn't associated with symptoms of depression and anxiety—only personal AI use showed this troubling pattern 3

Understanding Correlation Not Causation

Researchers emphasize that these findings show an association, not proof that chatbot use causes depression 2

2

. Dr. Jodi Halpern from UC Berkeley's Kavli Center for Ethics noted that "it could go in either direction" and "could be a vicious cycle" 3

3

. People already experiencing depressive symptoms or loneliness may be more inclined to turn to AI chatbots for companionship rather than the interactions triggering mental health issues 2

2

.

Dr. Sunny Tang from Northwell Health suggested that loneliness could be a critical factor, explaining that "a lot of people are feeling more and more isolated these days, whether it's because they're working remotely or for other reasons" . Social isolation is a strong predictor of mental health symptoms like depression, anxiety, and irritability .

Implications for AI Development and Mental Health Support

The findings raise important questions about how AI companies like ChatGPT, Google Gemini, and Microsoft Copilot should design their products 2

2

. Tang stressed that AI companies need better guardrails to ensure their products don't worsen existing mental health symptoms, urging them to ask, "Is there a way to build AI so that it can be more supportive of people with mental health needs?" .

Dr. Perlis acknowledged that "there's probably a subset of people where AI use is associated with no change in their mood, or even benefit," but warned that for others, AI use is "probably associated with worsening of their mood" 3

3

. While specialized therapeutic settings with CBT-based or clinically guided systems show some evidence of reducing depressive symptoms and loneliness when designed with safeguards, casual use for everyday companionship appears problematic 2

2

.

Experts suggest people should remain mindful of why they're turning to artificial voices and not hesitate to seek human connection and professional support when needed 2

. As AI tools become more interwoven with daily life, understanding whether frequent AI chat reflects a coping strategy for emotional distress or contributes to social withdrawal remains a priority for researchers and mental health professionals alike.
