Abstract
We conducted a randomized controlled trial among African-American patients attending a primary-care provider visit to compare efficacy of a computer-delivered tailored intervention to increase colorectal cancer (CRC) screening (n = 273) with non-tailored print material-an American Cancer Society brochure on CRC screening (n = 283). Health Belief Model constructs were used to develop tailored messages and examined as outcomes. Analysis of covariance models were used to compare changes between CRC knowledge and health belief scores at baseline and 1 week post-intervention. At 1 week, patients who received the computer-delivered tailored intervention had greater changes in CRC knowledge scores (P < 0.001), perceived CRC risk scores (P = 0.005), FOBT barriers scores (P = 0.034) and colonoscopy benefit scores (P < 0.001). Findings show that computer-delivered tailored interventions are an effective adjunct to the clinical encounter that can improve knowledge and health beliefs about CRC screening, necessary precursors to behavior change.
摘要
我们在参加初级保健就诊的非裔美国患者中进行了一项随机对照试验，比较了计算机提供的定制干预措施（n = 273）与非定制印刷材料（美国癌症协会关于 CRC 筛查的小册子，n = 283）对增加结直肠癌（CRC）筛查的效果。使用健康信念模型构建来制定定制信息，并将其作为结果进行检查。协方差分析模型用于比较干预前和干预后 1 周 CRC 知识和健康信念评分的变化。在 1 周时，接受计算机提供的定制干预的患者 CRC 知识评分的变化更大（P < 0.001），CRC 风险评分（P = 0.005），FOBT 障碍评分（P = 0.034）和结肠镜检查获益评分（P < 0.001）。研究结果表明，计算机提供的定制干预措施是临床就诊的有效辅助手段，可以提高对 CRC 筛查的知识和健康信念，这是行为改变的必要前提。
