Device Preference Predictors

Prior self-sampling experience, screening history, and subcohort membership were not significant predictors of device preference. Device preferences are driven primarily by immediate device characteristics rather than prior experience with self-sampling or screening attendance history. Sampling order was the sole significant predictor of device preference in comparisons involving Evalyn, consistent with a primacy bias. Age was the only significant predictor of preference in the FLOQSwab vs SensiGrip comparison, with older women marginally more likely to prefer FLOQSwab, though the effect was very small. Since prior experience, subcohort, and screening history did not influence preference, programme-level device replacement need not be tailored by population subgroup.
