2004 MAR 4 - (NewsRx.com & NewsRx.net) -- Study shows that viewing an informational video about participation in clinical trials is beneficial in educating patients about potential participation in a trial.
"A total of 262 women in the USA (161 breast cancer survivors and 101 controls) were exposed to a video vignette using modeling in which a physician discussed the concept of a clinical trial (CT) with a woman who was in the process of making a treatment decision," scientists writing in the journal Social Science & Medicine report.
"A pretest-post-test design was used and improvements in clinical trial knowledge and beliefs were assessed. Results indicate that video modeling is a powerful tool for increasing CT knowledge (pretest mean=41.5% correct, post-test mean=77.5% correct) but not for improving CT beliefs," wrote B. Curbow and colleagues, Johns Hopkins University, Johns Hopkins Bloomberg School of Public Health.
"Increased clinical trial knowledge, as measured by change scores, was associated with white race, lower levels of education and pretest breast cancer knowledge, more negative pretest CT beliefs, and a higher estimate of the lifetime probability that a woman will have breast cancer. When pretest CT knowledge was added to the analysis using hierarchical multiple regression, all variables except white race became nonsignificant; an increase in CT knowledge was associated with having lower pretest CT knowledge," the researchers wrote.
Results indicate that the effects of low ...
