Mean objective and subjective knowledge improved; higher decisional certainty seen with film
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.
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.
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 (β coefficient, 0.62). Mean subjective knowledge increased by 0.92 and 0.55 points, respectively, in the film+booklet and booklet-alone groups (β 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.
“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.
