aceBarriers and Facilitators to the Use of Large Language Model-Based Conversational Agents in Mental Healthcare: A Systematic Review
(1) Background/Objectives: Over one billion individuals globally live with mental health conditions, yet the treatment gap exceeds 75% in low- and middle-income countries. Large language model (LLM)-based conversational agents have emerged as a potentially scalable solution, though the evidence base remains nascent and largely pre-clinical. This review synthesises barriers and facilitators to their implementation in mental healthcare using the Consolidated Framework for Implementation Research (CFIR). (2) Method…
LLM-based conversational agents offer 24/7 availability as a scalable way to help address the mental health treatment gap.
LLM-based conversational agents in mental healthcare frequently show inadequate crisis detection, creating critical safety deficiencies.
Evidence base is nascent and largely pre-clinical, and reported frequencies are study-level counts not population prevalence, with major gaps in implementation process evaluation.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0183 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
