User Engagement Clusters of an 8-Week Digital Mental Health Intervention Guided by a Relational Agent (Woebot): Exploratory Study.
Hoffman V, Flom M, Mariano TY, et al.· J Med Internet Res· 2023
With the proliferation of digital mental health interventions (DMHIs) guided by relational agents, little is known about the behavioral, cognitive, and affective engagement components associated with symptom improvement over time. Obtaining a better understanding could lend clues about recommended use for particular subgroups of the population, the potency of different intervention components, and the mechanisms underlying the intervention's success. This exploratory study applied clustering techniques to a range of engagement indicators, which were mapped to the intervention's active compone…
Effectiveness of a Web-based and Mobile Therapy Chatbot on Anxiety and Depressive Symptoms in Subclinical Young Adults: Randomized Controlled Trial.
Karkosz S, Szymański R, Sanna K, et al.· JMIR Form Res· 2024RCT
There has been an increased need to provide specialized help for people with depressive and anxiety symptoms, particularly teenagers and young adults. There is evidence from a 2-week intervention that chatbots (eg, Woebot) are effective in reducing depression and anxiety, an effect that was not detected in the control group that was provided self-help materials. Although chatbots are a promising solution, there is limited scientific evidence for the efficacy of agent-guided cognitive behavioral therapy (CBT) outside the English language, especially for highly inflected languages. This study a…

Effectiveness of artificial intelligence chatbots on mental health & well-being in college students: a rapid systematic review.
Nyakhar S, Wang H· Front Psychiatry· 2025Systematic Review
Mental health disorders among college students have surged in recent years, exacerbated by barriers such as stigma, cost associated with treatment, and limited access to mental health providers. Artificial intelligence (AI)-driven chatbots have emerged as scalable, stigma-free tools to deliver evidence-based mental health support, yet their efficacy specifically for college populations remains underexplored. This systematic rapid review evaluates the effectiveness of chatbots in improving mental health outcomes (e.g., anxiety, depression) and well-being among college students while identifyin…
Network-based artificial intelligence in mental healthcare: A systematic review of chatbots, artificial intelligence/machine learning models and ethical considerations in global healthcare networks.
Rezaei Z, Khorraminia A, Shi D, et al.· Digit Health· 2026Systematic Review
This systematic review examines how artificial intelligence (AI), including machine learning (ML) models and AI-powered chatbots, contributes to the diagnosis, treatment and ethical governance of mental healthcare. It explores how AI-driven systems form interconnected healthcare networks that enhance accessibility, personalization and resilience of mental health services, aligning with the United Nations Sustainable Development Goal 3: Good Health and Well-Being. A comprehensive search across PubMed, IEEE Xplore and Google Scholar (2017-2024) was conducted using Boolean combinations of "AI,"…

Direct quotes

In my experience (granted it’s only 2 so far) even real life therapists are dismissively optimistic so I would doubt it. I remember I tried woebot once and it got me so irritated with not being able to handle my depression.

Woebot : A. I. CBT bot. I've been using this service for a couple of weeks and it's a interesting substitute for therapy. If you want to learn CBT techniques, with a bit more interaction than a self-help book, you might like to give it a try. I think it is helping me.
