Abstract

Objectives To identify which information items potential participants and research nurses rank as the most important, and the reasons for this, when considering participation in a randomised controlled trial.

Design Q-methodology approach alongside a think-aloud process. Using a vignette outlining a hypothetical trial, participants were asked to rank statements about informational items usually included in a participant information leaflet (PIL) on a Q-grid, while undertaking a real-time think-aloud process to elicit the underpinning decision processes. Analysis of quantitative data was conducted using descriptive statistics and qualitative data was coded using content analysis.

Participants 20 participants (10 potential trial participants and 10 research nurses).

Setting UK-based participants.

Results Ten research nurses and 10 potential trial participants provided data for the study. Both stakeholder groups ranked similar statements in their top three most important statements, with ‘What are the possible disadvantages and risks of taking part?’ featuring in both. However, considerable variability existed between the groups with regard to their ranking of statements of least importance. Participants identified that sufficient information to make a decision was secured using around 14 items. Participants also identified other items of importance not routinely included in PILs.

Conclusions This study has provided a unique insight into how and why different trial stakeholder groups rank informational items currently contained within PILs. These results have implications for those developing future PILs and those who develop guidance on their content; PILs should focus most on the information items that potential trial participants want and need to make an informed choice about trial participation.
