To evaluate the applicability of an evidence-based video intervention to promote informed decision making for prostate cancer screening among African American men with different levels of health literacy.
Forty nine African American men participated in interviewer-administered, pretest and posttest interviews between January and March 2008. Health literacy status was assessed with the Test of Functional Health Literacy in Adults. Repeated measures analysis of covariance (ANCOVA), McNemar or binomial distributions were computed to assess pretest and posttest differences in knowledge. Descriptive statistics were produced to describe participants' perceptions of the information presented in the video.
Results indicated that men with functional health literacy had higher mean levels of prostate cancer screening knowledge at baseline than men with inadequate health literacy. The between-group (F2,44= 4.84; p = .013) and within-group (F1,44 = 5.16; p = .028) test results from repeated-measures ANCOVA indicated that preexisting group differences in prostate cancer knowledge had lessened after intervention exposure. Nearly all men rated the information presented in the video as credible (98%), trustworthy (96%), interesting (100%), understandable (94%), and complete (96%).
Results from this exploratory study suggest that the video intervention is suitable for use with African American men with different health literacy characteristics in 2 counties in the greater Florida panhandle region. More research is recommended to evaluate the impact of the intervention on men's intentions to undergo screening and actual screening behavior.
评估基于证据的视频干预措施在促进具有不同健康素养水平的非裔美国男性进行前列腺癌筛查方面的适用性。
49 名非裔美国男性于 2008 年 1 月至 3 月期间参加了访员管理的预测试和后测试访谈。健康素养状况通过成年人功能性健康素养测试进行评估。采用重复测量协方差分析（ANCOVA）、McNemar 或二项式分布来评估知识的前后测差异。采用描述性统计来描述参与者对视频中呈现的信息的看法。
结果表明，具有功能性健康素养的男性在基线时的前列腺癌筛查知识平均水平高于健康素养不足的男性。组间（F2,44=4.84；p=0.013）和组内（F1,44=5.16；p=0.028）重复测量 ANCOVA 的测试结果表明，干预暴露后，前列腺癌知识的预先存在的组间差异已经减小。几乎所有男性都认为视频中呈现的信息具有可信度（98%）、可信赖性（96%）、趣味性（100%）、可理解性（94%）和完整性（96%）。
这项探索性研究的结果表明，该视频干预措施适用于佛罗里达州狭长地带的 2 个县的具有不同健康素养特征的非裔美国男性。建议进行更多的研究来评估该干预措施对男性进行筛查的意愿和实际筛查行为的影响。
