To determine whether the influence of a leaflet on mouth cancer improves knowledge, related attitudes and intention to accept a mouth screen.
Randomized controlled trial.
Dental and medical waiting rooms in the North West of England.
Nine hundred and forty nine patients from 16 practices were invited to participate.
Standardized multi-item scales of six outcome measures including knowledge, beliefs and intention to accept an oral cancer screen.
A patient information leaflet was given to a randomized intervention group of patients. A single sheet questionnaire was completed by both groups of patients (immediately following leaflet administration in the intervention arm of study).
t tests were used to compare outcome variables between patients with and without access to the leaflet with Boneferroni correction.
Participation rate was high (91%). Knowledge (P <0.001) and intentions (P = 0.003) benefited from patient access to leaflet. Anxiety was not raised with leaflet exposure. Some beliefs about the screening procedure appeared to be slightly improved by reading the leaflet (p <0.05).
This study supports previous findings of an immediate positive effect of an information leaflet on patients' knowledge of oral cancer and willingness to accept an oral cancer screen.
确定一份宣传册对口腔癌的影响是否能提高相关知识、态度以及接受口腔筛查的意愿。
随机对照试验。
英格兰西北部的牙科和医疗候诊室。
邀请了来自16家医疗机构的949名患者参与。
采用标准化多项目量表对六项结果指标进行测量，包括知识、信念以及接受口腔癌筛查的意愿。
向随机分组的干预组患者发放一份患者信息宣传册。两组患者均填写一份单页问卷（在研究的干预组发放宣传册后立即填写）。
采用t检验，经邦费罗尼校正后比较有和没有获得宣传册的患者之间的结果变量。
参与率很高（91%）。患者获得宣传册后，知识水平（P <0.001）和意愿（P = 0.003）都有所提高。接触宣传册并未引发焦虑情绪。阅读宣传册后，对筛查程序的一些信念似乎略有改善（p <0.05）。
本研究支持了之前的研究结果，即信息宣传册对患者口腔癌知识及接受口腔癌筛查意愿有即时的积极影响。
