Visual Elicitation Qualitative Content Analysis

Photo elicitation specifically refers to the use of photographs as interview stimuli, following the tradition established by Collier (1957) and theorized by Harper (2002). Visual elicitation is a broader term that encompasses any visual stimulus — drawings, maps, diagrams, video stills, or artifacts — used to prompt participant responses. VEQCA applies to any of these visual modalities, not only photographs.

This depends on your epistemological stance. A deductive approach develops the frame from theory or prior literature before analysis begins, testing pre-specified categories against the data. An inductive approach derives categories from the data itself, developing and refining the frame iteratively. A combined approach starts with broad deductive categories and adds inductive sub-categories. All three are legitimate in qualitative content analysis; the choice must match your stated methodology and research question.

Inter-coder reliability (often reported as Cohen's kappa or percentage agreement) is appropriate if you are working with a second coder and a finalized coding frame. A kappa above 0.70 is typically considered acceptable. However, many qualitative content analysis studies use a single coder with a detailed audit trail of coding decisions as the primary trustworthiness mechanism. If you use reliability statistics, report them alongside — not instead of — a description of the iterative frame-development process.

Yes. Participant-generated image approaches such as photovoice or diary photography give participants control over what is documented, shifting interpretive power toward them. The resulting images are then used as elicitation stimuli in interviews or focus groups. This participatory variant is compatible with VEQCA, but it adds steps — briefing participants on image production, managing data volumes, and addressing ethics around self-generated sensitive content — that must be planned in advance.

There is no fixed number, but VEQCA studies typically involve 10–30 participants in individual elicitation interviews, or 3–6 focus groups. The relevant criterion is whether the category system has reached saturation — the point at which new data no longer produce new categories or substantially modify existing ones. Because image stimuli generate focused, concentrated responses, saturation can sometimes be reached with smaller samples than in purely open-ended interview designs.
