Abstract

Objective: Experimental vignette designs are used to systematically test the effects of medical communication. We tested the impact of two methodological choices –gender congruence and vignette modality– on analogue patient reported outcomes. Methods: In an online experiment using a vignette portraying an oncological bad news consultation, we manipulated (1) gender congruence between the analogue and the vignette patient, and (2) vignette modality, i.e., text, audio, or video. Cancer-naïve students acting as analogue patients (N = 209, 22 ± 3 years old, 75% F) were assigned one randomly-selected vignette variant and completed questionnaires. Using 3 × 2 (repeated-measures) ANOVAs, we tested main and interaction effects of gender congruence and modality on self-reported engagement, recall, trust, satisfaction and anxiety. Results: We found no main effects of gender congruence or modality on any of the outcomes, nor any interaction effects between modality and congruence. Conclusion: Our results indicate that researchers may needlessly create gender-congruent vignettes at considerable cost and effort. Also, the currently assumed superiority of videos over other modalities for experimental vignette-based research may be inaccurate. Practice implications: Although further testing in an offline format and among different populations is warranted, decisions regarding gender congruence and modality for future vignette-based studies should be based primarily on their specific aims.
