African American men are at a higher risk of developing and dying from prostate cancer compared to white men. The serum prostate-specific antigen (PSA) screening test has a high risk of false-positive results and overdiagnosis; therefore, it is not routinely recommended. Rather, men are encouraged to make individualized decisions with their medical providers, after being fully informed about its potential benefits, limitations, and risks.
This study aimed to describe the development and pilot testing of an interactive Web-based decision aid (DA; Prostate Cancer Screening Preparation [PCSPrep]) for African American men, designed to promote informed decision making for prostate cancer screening.
Four focus groups (n=33) were conducted to assess men's reactions to DAs developed in prior studies and gather information to modify the content and format. The pilot test employed a pre-posttest evaluation design. A convenience sample of 41 men aged 45-70 years with no history of prostate cancer was recruited from community settings. Participants completed online surveys before and after using PCSPrep that assessed prostate cancer screening knowledge, decision self-efficacy, decisional conflict, and preparation for decision making.
Use of PCSPrep was associated with a significant increase in prostate cancer knowledge (49% vs 62% correct responses; P<.001), and men also experienced less decisional conflict (24 vs 15 on a scale of 0-100; P=.008). No changes in self-efficacy about decision making or screening preferences were observed. Most men (81%) reported that using PCSPrep prepared them to make informed decisions in partnership with their provider.
PCSPrep was an acceptable DA that improved men's knowledge, reduced decisional conflict, and promoted the perception of being prepared for shared decision making. Further research is needed to test the DA in a larger randomized trial.
与白人男性相比,非裔美国男性患前列腺癌和死于前列腺癌的风险更高。血清前列腺特异性抗原(PSA)筛查试验存在较高的假阳性结果和过度诊断风险;因此,不常规推荐。相反,鼓励男性在充分了解其潜在益处、局限性和风险后,与医疗服务提供者一起做出个体化决策。
本研究旨在描述一种用于非裔美国男性的交互式网络决策辅助工具(DA;前列腺癌筛查准备(PCSPrep)的开发和试点测试,旨在促进对前列腺癌筛查的知情决策。
进行了四项焦点小组(n=33),以评估男性对先前研究中开发的 DA 的反应,并收集信息以修改内容和格式。试点测试采用前后测试评估设计。从社区环境中招募了 41 名年龄在 45-70 岁之间、无前列腺癌病史的便利样本男性。参与者在使用 PCSPrep 前后完成了在线调查,这些调查评估了前列腺癌筛查知识、决策自我效能、决策冲突和决策准备情况。
使用 PCSPrep 与前列腺癌知识的显著增加相关(正确回答的百分比从 49%增加到 62%;P<.001),男性的决策冲突也减少(从 24 分降至 15 分,范围为 0-100;P=.008)。关于决策或筛查偏好的自我效能感没有变化。大多数男性(81%)报告使用 PCSPrep 使他们能够与提供者合作做出明智的决策。
PCSPrep 是一种可接受的 DA,它提高了男性的知识水平,降低了决策冲突,并促进了他们对共同决策的准备感知。需要进一步的研究来在更大的随机试验中测试该 DA。
