Brief summary

Few studies have investigated how to improve parents' understanding of clinical trials they are asked to join or how to reduce any possible distress. The INPUT study proposed will explore the effect of positive, negative or neutral language on parents' understanding, stress and willingness to participate in clinical trials.

Interventions

The INPUT study proposed uses a randomised 2 x 3 x 2 factorial design to compare 12 different versions of an information leaflet describing an imaginary clinical trial in preterm infants. Parents will be randomly assigned to read one of 12 combinations of contrasting descriptions of (1) background risk, (2) the primary endpoint and (3) risks of participation, using 'negative', 'neutral' or 'positive' language. Through a face-to-face questionnaire performed immediately after reading the leaflet,

Through a face-to-face questionnaire performed immediately after reading the leaflet, the study will evaluate the effects of these contrasting expressions on the parents' level of understanding of a hypothetical clinical trial, their level of anxiety and their willingness to participate in the trial.
