Participation in clinical trials as viewed by the patient: understanding cultural and emotional aspects which influence choice.
BACKGROUND
Patients invited to take part in a clinical trial may evoke an archetype on which they may base their decision of adherence to participation, instead of on the study itself.


METHODS
A 17-item, multiple choice questionnaire was developed, tested and then administered to 102 Italian-speaking patients with advanced lung or breast cancers who had never been exposed to participation in a trial.


RESULTS
The questionnaire was answered by all patients. Eighty-five percent were positive about trial participation. Demographic factors did not influence patients' willingness to participate. Trust in the investigator (76%) or in the institute (64%) and hope of receiving a new chance for cure (78%) were cited as reasons to accept participation. A minority was concerned by potential conflicts of interest (31%) or the thought of being 'guinea pigs' (36%), and feared that doctors were interested in advancing their own research, even though there were more efficient drugs available (28%). Fifty percent feared receiving a little-known medicine, and 76% considered that a thorough explanation of toxicity/safety of the proposed treatment helped them decide.


CONCLUSIONS
Several prejudices, fears and some hopes have been captured by the questionnaire. Understanding such specifics will improve patient information leading patients to a more conscious motivation in deciding whether to participate in a clinical trial.
