Until there is a definitive demonstration that early diagnosis and treatment of prostate cancer reduces disease-related mortality, it is imperative to promote informed screening decisions by providing balanced information about the potential benefits and risks of prostate cancer screening. Within a community/academic collaboration, we conducted a randomized trial of a printed booklet and a videotape that were designed for African American (AA) men. The purpose of the trial was to determine the effect of the interventions on knowledge, decisional conflict, satisfaction with the screening decision, and self-reported screening.
Participants were 238 AA men, ages 40 to 70 years, who were members of the Prince Hall Masons in Washington, DC. Men were randomly assigned to the (a) video-based information study arm, (b) print-based information study arm, or (c) wait list control study arm. Intervention materials were mailed to men at home. Assessments were conducted at baseline, 1 month, and 12 months postintervention. Multivariate analyses, including ANCOVA and logistic regression, were used to analyze group differences.
The booklet and video resulted in a significant improvement in knowledge and a reduction in decisional conflict about prostate cancer screening, relative to the wait list control. Satisfaction with the screening decision was not affected by the interventions. Self-reported screening rates increased between the baseline and the 1-year assessment, although screening was not differentially associated with either of the interventions. In exploratory analyses, prostate-specific antigen testing at 1 year was more likely among previously screened men and was associated with having low baseline decisional conflict.
This study represents one of the first randomized intervention trials specifically designed to address AA men's informed decision making about prostate cancer screening. We have developed and evaluated culturally sensitive, balanced, and disseminable materials that improved knowledge and reduced decisional conflict about prostate cancer screening among AA men. Due to the high incidence and mortality rates among AA men, there is a need for targeted educational materials, particularly materials that are balanced in terms of the benefits and risks of screening.
在有确凿证据表明前列腺癌的早期诊断和治疗能降低疾病相关死亡率之前,通过提供有关前列腺癌筛查潜在益处和风险的平衡信息来促进明智的筛查决策至关重要。在一项社区/学术合作中,我们针对非裔美国(AA)男性开展了一项关于印刷手册和录像带的随机试验。该试验的目的是确定这些干预措施对知识、决策冲突、对筛查决策的满意度以及自我报告的筛查情况的影响。
参与者为238名年龄在40至70岁之间的华盛顿特区王子堂共济会成员中的AA男性。男性被随机分配到(a)基于视频的信息研究组、(b)基于印刷品的信息研究组或(c)等待列表对照组。干预材料被邮寄到男性家中。在干预前、干预后1个月和12个月进行评估。采用包括协方差分析和逻辑回归在内的多变量分析来分析组间差异。
相对于等待列表对照组,手册和录像带使前列腺癌筛查的知识有显著改善,决策冲突减少。对筛查决策的满意度不受干预措施影响。自我报告的筛查率在基线和1年评估之间有所增加,尽管筛查与任何一种干预措施均无差异关联。在探索性分析中,1年前筛查过的男性进行前列腺特异性抗原检测的可能性更大,且与基线决策冲突较低有关。
本研究是首批专门设计用于解决AA男性关于前列腺癌筛查的明智决策问题的随机干预试验之一。我们开发并评估了具有文化敏感性、平衡且可传播的材料,这些材料改善了AA男性对前列腺癌筛查的知识并减少了决策冲突。由于AA男性中的高发病率和死亡率,需要有针对性的教育材料,特别是在筛查益处和风险方面保持平衡的材料。
