Human–AI triangulation in qualitative research: a methodological proof-of-concept using interview data on pathological gambling
摘要
The integration of artificial intelligence (AI) into qualitative research promises to augment traditional methodologies, yet its comparative analytical power remains underexplored. This exploratory proof-of-concept study employs a triangulation approach to compare thematic analyses of semi-structured interviews with pathological gamblers in Uruguay—one conducted by a human researcher and another assisted by a generative AI model (GPT-4). Our findings illustrate convergence in identifying core themes, such as the illusion of control and the role of gambling in emotional regulation. However, significant divergences emerged in interpretive depth: the human analysis provided critical, contextualized insights into sociocultural and existential dimensions, while the AI offered systematic efficiency in pattern recognition and thematic synthesis. We demonstrate that a hybrid methodology does not produce contradictory results but rather generates complementary knowledge. Within the limits of this proof-of-concept, AI appears as a potentially auxiliary tool that can enhance the rigor and scope of qualitative analysis in mental health and beyond. A brief but important clarification: this is not a clinical or epidemiological study. It is a methodological proof-of-concept. We use the interview on pathological gambling as a substantive case to illustrate how human and AI-assisted qualitative analysis can be systematically compared. Due to the small sample size (N = 7) and the lack of reproducibility assessment (single GPT‑4 run), findings are preliminary and should be viewed as a procedural illustration rather than reliable evidence of human‑AI agreement. Replication with multiple runs and more diverse samples is required before any generalized claims can be made.
