Influence of evidence-based information and the usage of the term "mammography" on women's willingness to undergo mammography screening: randomized controlled trial - Influence of evidence-based information and the usage of the term "mammography" on women's willingness to undergo mammography screening: randomized controlled trial

Results: Between Dec 19, 2017, and Dec 20, 2017, we assigned 330 women to promotional sentences with "mammography" (n=88; Willingness to undergo the esamination 7.3; SD 3.0), evidence-based information with "mammography" (n=80; 7.4; SD 2.8), promotional sentences with "A" (n=90; 7.5; SD 2.3), or evidence-based sentences with "A" (n=72; 6.3; SD 2.4). The interaction between the type of sentences and the use of the term "mammography" was statistically significant (Generalized linear model p=0.02). When the alphabet "A" was used, mammography campaign's sentences increased women's willingness to undergo the examination compared with the evidence-based information (Cohen's d=0.56. 95% CI; 0.24 to 0.87. T-test; p<0.001), but not among the groups where the term "mammography" was used (p=0.87). When the evidence-based information was presented, the term "mammography" motivated women more than the alphabet "A" (Cohen's d=0.43; 95% confidence interval; 0.12 to 0.75; T-test p<0.01), while there was no significant difference among the groups where the promotional descriptions were used (p=0.32). Conclusions: Not only the sentences used in mammography screening campaigns but also the use of the term "mammography" itself could make women more willing to undergo the examination.
