FRIDAY, April 19, 2019 (HealthDay News) — An informational film can improve knowledge and reduce decisional conflict for individuals considering participating in lung cancer screening, according to a study published online April 19 in the Annals of the American Thoracic Society<\/i>.<\/p>\n
Mamta Ruparel, M.B.B.S., Ph.D., from University College London, and colleagues examined the impact of a novel informational film on informed decision making among individuals considering participating in lung cancer screening. A subset of participants from the Lung Screen Uptake Trial were randomly assigned to view the film and receive a written informational booklet or receive the booklet alone. The final analysis included 229 participants.<\/p>\n
The researchers found that subjective and objective knowledge scores significantly improved for both groups after the intervention. Greatest improvement was seen in the film+booklet group, with a mean objective knowledge improvement of 2.16 and 1.84 points, respectively, in the film+booklet group versus the booklet-alone group (\u03b2 coefficient, 0.62). Mean subjective knowledge increased by 0.92 and 0.55 points, respectively, in the film+booklet and booklet-alone groups (\u03b2 coefficient, 0.32). Higher decisional certainty was also seen in the film+booklet group (mean 8.5\/9 versus 8.2\/9). No differences were seen between the groups in the final screening participation rates.<\/p>\n
“The developed information film has positively impacted knowledge and decisional conflict more than the booklet alone without reducing uptake of low-dose computed tomography,” the authors write.<\/p>\n
