Reimagining Qualitative Research with AI
Automated Thematic Analysis with Multi-Agent LLMs
Our study introduces Collaborative Theme Identification Agent (CoTI), a groundbreaking multi-agent large language model framework. CoTI automates labor-intensive qualitative thematic analysis, traditionally subjective and difficult to scale, by leveraging specialized AI agents to extract clues, identify themes, and generate structured codebooks from clinical interview data. This innovation is critical for advancing patient-centered care, especially in chronic disease management where understanding patient experience is paramount.

Introduction to CoTI
Qualitative thematic analysis, while essential for understanding patient experiences in fields like chronic disease management, has traditionally been labor-intensive, subjective, and difficult to scale. Our research addresses these challenges by developing CoTI, a multi-agent Large Language Model (LLM) framework designed to automate this critical process. CoTI enables the efficient extraction of key insights, theme identification, and codebook generation, making qualitative research more accessible and reproducible.
CoTI's Multi-Agent Framework
CoTI integrates three specialized AI agents—Instructor, Thematizer, and CodebookGenerator—each designed to replicate and enhance key steps of manual thematic analysis. The Instructor refines instruction prompts, the Thematizer extracts clues and identifies themes, and the CodebookGenerator summarizes themes into a structured codebook. This modular design allows for both fully automated operation and human-in-the-loop refinement.

Benchmarking CoTI Against Baselines
CoTI consistently outperformed traditional Natural Language Processing (NLP) models and basic Large Language Models (LLMs) across critical evaluation metrics, demonstrating its superior ability to mimic expert human qualitative analysis. Its refined instruction prompts and multi-run aggregation strategy contribute to higher accuracy and efficiency.
| Metric | Traditional NLP (e.g., LDA, Top2Vec) | Basic LLM (QwQ-32B) | Junior Investigators (Manual) | CoTI |
|---|---|---|---|---|
| Codebook Cosine Similarity (vs. Senior Investigator) | ~0.34 (Average) | 0.508 | N/A (partial analysis) | 0.621 |
| Clue Extraction F1 Score (vs. Senior Investigator) | N/A | 0.540 | N/A (focused on themes) | 0.569 (+5.37%) |
| Theme Identification Cosine Similarity (vs. Senior Investigator) | N/A | 0.411 | Variable, often lower than CoTI (e.g., 0.41) | 0.431 (+4.87%) |
| Thematizer Response Time per Interview | Hours/Days (Manual interpretation) | 3 minutes | Hours/Days | 1 minute |
| Codebook Generator Response Time | Hours/Days (Manual interpretation) | 2 minutes | N/A | 10 seconds |
Insights on AI-Human Collaboration
Our study explored the impact of junior investigators' feedback on CoTI's performance. While AI-human collaboration is often assumed to enhance AI outputs, our results showed only marginal gains, and in some cases, feedback could even degrade theme similarity when CoTI alone already performed strongly. This suggests a potential for automation bias and over-reliance on AI by less experienced human collaborators, limiting their independent critical thinking.

Key Contributions & Generalizability
CoTI offers a robust, multi-agent framework that automates the core processes of qualitative thematic analysis, achieving outputs highly similar to senior investigators. Its iterative prompt optimization and multi-run aggregation strategies ensure contextual and emotional depth. Beyond heart failure, CoTI demonstrated strong generalizability by producing a codebook with significant overlap to expert-generated codebooks on a separate COVID-19 healthcare dataset, highlighting its broad applicability across various qualitative research contexts.
Generalizability: COVID-19 Transcripts
CoTI successfully applied its framework to a different healthcare qualitative dataset focused on the health system's response to COVID-19 in Sierra Leone, comprising 21 interview transcripts. The model's final codebook showed a strong overlap with codebooks generated by experts, underscoring CoTI's ability to identify relevant themes and generalize its performance across diverse qualitative research contexts.
Key Insight: Strong overlap with expert-generated codebooks on an independent COVID-19 dataset, validating CoTI's adaptability and robustness.
