To explore whether Australian women's support for government funding of mammographic screening is influenced by 'framing effect'.
Self-administered survey of 701 women in general practice to elicit their support for government funding of each of four mammographic screening programs where benefits were expressed as a relative risk reduction (RRR); absolute risk reduction (ARR); number needed to screen (NNS) and number of cases detected for additional death avoided.
The proportion of respondents indicating they 'definitely would support funding' was significantly greater when benefits were expressed as RRR than ARR (chi 2(1) = 148.4, p < 0.0001), NNS (chi 2(1) = 126.4, p < 0.0001) or number of cases detected for additional deaths avoided (chi 2(1) = 29.0, p < 0.0001). 55.8% of women were not influenced by 'framing effect'. Younger women and those with higher educational levels were more likely to be susceptible to 'framing effect'.
Having demonstrated its influence among these women, 'framing effect' should be acknowledged in future research.
探讨澳大利亚女性对政府资助乳房X线筛查的支持是否受“框架效应”影响。
对701名全科医疗女性进行自填式调查，以了解她们对四个乳房X线筛查项目中每个项目政府资助的支持情况，其中益处分别以相对风险降低率（RRR）、绝对风险降低率（ARR）、需筛查人数（NNS）以及为避免额外死亡而检测出的病例数来表示。
当益处以RRR表示时，表明“肯定会支持资助”的受访者比例显著高于以ARR表示时（卡方检验χ2(1)=148.4，p<0.0001）、以NNS表示时（χ2(1)=126.4，p<0.0001）或为避免额外死亡而检测出的病例数表示时（χ2(1)=29.0，p<0.0001）。55.8%的女性不受“框架效应”影响。年轻女性和受教育程度较高的女性更容易受到“框架效应”影响。
已证明“框架效应”在这些女性中存在影响，未来研究应予以承认。
