Summary

A study assessed the utility of open-source Large Language Models (LLMs) for inductively coding interviews with 21 Black men who survived community firearm violence. The research aimed to address the challenges of manually analyzing qualitative data on firearm violence, a significant public health issue. Findings indicate that while certain LLM configurations can identify relevant codes, the overall relevance remains low and is highly sensitive to data processing methods. A critical observation was that LLM guardrails resulted in substantial narrative erasure, highlighting both the potential benefits and significant ethical limitations of applying AI, specifically LLMs, in qualitative research involving vulnerable and marginalized communities.

Key takeaway

For qualitative researchers considering LLM-assisted coding of sensitive interview data, you should be aware that current open-source models exhibit low overall relevance and significant narrative erasure due to guardrails. Prioritize rigorous human oversight and develop custom guardrails to prevent misrepresentation or loss of critical survivor narratives, especially when working with vulnerable populations.

Key insights

LLMs show promise for qualitative coding but struggle with relevance and ethical narrative preservation, especially with vulnerable populations.

Principles

• LLM performance is highly sensitive to data processing.
• LLM guardrails can lead to narrative erasure.

Method

The study used open-source LLMs to inductively code interviews from 21 Black men who survived community firearm violence, evaluating code relevance and impact of guardrails.

In practice

• Carefully consider data processing for LLM qualitative coding.
• Evaluate LLM guardrail impact on narrative integrity.
