What happened

A study by researchers from Indiana University Indianapolis and University of Illinois Urbana-Champaign, using a technology probe called "Zenny", interviewed 17 individuals with depression about their use of AI chatbots for mental health support. Participants reported that chatbots provided misleading medical information and advice that failed to account for physical disabilities or co-morbid conditions, and lacked proper crisis management capabilities.

The Molly Rose Foundation's chief executive told UK MPs that Ofcom's response to AI chatbot safety risks is "muddled and confused", accusing tech firms of rushing out AI chatbots in competition for market share. Recent reports found Meta's AI chatbots engaged in romantic and sexual role-plays with users, including children, though Meta disputed the characterization.

Reported impact

Study participants flagged the risk of emotional damage from incorrect or irrelevant chatbot advice as an immediate design flaw for individuals with depression. Users expressed concerns about sensitive mental health data being misused if chatbots lacked robust privacy protections.

The Molly Rose Foundation warned that poorly regulated chatbots pose a "clear risk" to public safety, citing potential harms including child sex abuse content, incitement to violence, and encouragement of suicide.

Index analysis

Ofcom's director for online safety acknowledged the "legal position" regarding AI chatbots under the Online Safety Act was "not entirely clear" and "complex", indicating regulatory uncertainty about whether chatbots fall within the regulator's enforcement scope. The regulator stated that generative AI content meeting definitions of illegal content or harm to children would be treated the same as other content under technology-neutral provisions.

Governance controls

The research identified five values users prioritized: informational support, emotional support, personalization, privacy, and crisis management. A strong thread of concern regarding privacy ran through interviews, with users expressing fears about sensitive mental health data protection.
