headline: Psychological support for depression and anxiety across chronic illness contexts: a comparative evaluation of three general-purpose AI chatbots
dek: Background Digital mental health tools, including general-purpose artificial intelligence (AI) chatbots, may provide accessible and low-threshold psychological support for people living with chronic conditions. However, their value in this population depends not only on recognizing depression or anxiety, but also on understanding how psychological distress is shaped by disease-specific experiences and when self-guided support should transition toward professional care. We evaluated the appropriateness, contextua…
gain_title: In simulated chronic-illness patients, chatbots recognized distress and gave emotional support consistently well, with 90.0% of ChatGPT responses meeting the appropriateness threshold.
problem_title: Support became less reliable for moderate presentations and for disease-specific context, with major clinical or safety errors in 10.0% of Gemini and 15.0% of Doubao first-round responses.
trace_subject: General-purpose AI chatbots giving psychological support for depression and anxiety in type 2 diabetes and chronic urticaria scenarios
gain_reading: In simulated chronic-illness patients, chatbots recognized distress and gave emotional support consistently well, with 90.0% of ChatGPT responses meeting the appropriateness threshold.
gain_evidence: Recognition and emotional support was consistently strong across systems | 90.0% of ChatGPT, 75.0% of Gemini, and 55.0% of Doubao responses meeting the prespecified appropriateness threshold
problem_reading: Support became less reliable for moderate presentations and for disease-specific context, with major clinical or safety errors in 10.0% of Gemini and 15.0% of Doubao first-round responses.
problem_evidence: Major clinical or safety errors occurred in 0%, 10.0%, and 15.0% of first-round ChatGPT, Gemini, and Doubao responses, respectively | compared with 58.3% of responses to moderate presentations
quick_read: Researchers tested ChatGPT, Gemini, and Doubao with 20 simulated-patient scenarios covering type 2 diabetes and chronic spontaneous urticaria. Each scenario was submitted twice to each system, producing 120 responses that blinded raters scored for appropriateness, contextualization, referral, and safety.

The results suggest chatbots may serve as an accessible first layer of emotional support, but they were weaker when distress was moderate or tied to a specific disease. Because the test used simulated patients, how this performs with real users remains unresolved, and the authors argue for integration with professional care rather than substitution.
limitation: The evaluation used standardized simulated patients and only 20 scenarios, and test-retest consistency was only moderate, so results may not reflect real-world use by actual patients.
tag: Dual reading
key_points: Appropriateness differed significantly across systems (P = 0.002): 90.0% for ChatGPT, 75.0% for Gemini, and 55.0% for Doubao. | All responses to mild presentations were appropriate, versus 58.3% for moderate presentations. | Contextualization was less consistent for urticaria, especially for flare unpredictability, pruritus, sleep disruption, and illness uncertainty. | Test-retest consistency was moderate and varied between systems.
rundown: The study used matched mild and moderate depression and anxiety presentations alongside condition-specific distress, such as diabetes self-management and uncertainty over urticaria flares. This allowed comparison across two contrasting chronic illness contexts.

Differences were small for recognition and emotional support but larger for chronic-illness contextualization (P = 0.001), psychological support and referral (P = 0.002), and psychosomatic balance and safety (P<0.001).

The authors conclude that implementation should emphasize context-sensitive guidance, severity-responsive referral, and clear integration with professional care.
