Little is known about the impact of data collection method on self-reported cancer screening behaviours, particularly among hard-to-reach populations. The purpose of this study is to examine the effects of data collection mode on response to indicators of cancer screenings by unmarried middle-aged and older women.
Three survey methods were evaluated for collecting data about mammography and Papanicolaou (hereafter, Pap) testing among heterosexual and sexual minority (e.g., lesbian and bisexual) women. Women ages 40-75 were recruited from June 2003 - June 2005 in Rhode Island. They were randomly assigned to receive: Self-Administered Mailed Questionnaire [SAMQ; N = 202], Computer-Assisted Telephone Interview [CATI; N = 200], or Computer-Assisted Self-Interview [CASI; N = 197]. Logistic regression models were computed to assess survey mode differences for 13 self-reported items related to cancer screenings, adjusting for age, education, income, race, marital status, partner gender, and recruitment source.
Compared to women assigned to CATI, women assigned to SAMQ were less likely to report two or more years between most recent mammograms (CATI = 23.2% vs. SAMQ = 17.7%; AOR = 0.5, 95% CI = 0.3 - 0.8) and women assigned to CASI were slightly less likely to report being overdue for mammography (CATI = 16.5% vs. CASI = 11.8%; AOR = 0.5, 95% CI = 0.3 - 1.0) and Pap testing (CATI = 14.9% vs. CASI = 10.0%; AOR = 0.5, 95% CI = 0.2 - 1.0). There were no other consistent mode effects.
Among participants in this sample, mode of data collection had little effect on the reporting of mammography and Pap testing behaviours. Other measures such as efficiency and cost-effectiveness of the mode should also be considered when determining the most appropriate form of data collection for use in monitoring indicators of cancer detection and control.
关于数据收集方法对自我报告的癌症筛查行为的影响，人们了解甚少，尤其是在难以接触到的人群中。本研究的目的是检验数据收集方式对未婚中老年女性癌症筛查指标反应的影响。
评估了三种调查方法，用于收集异性恋和性少数群体（如女同性恋和双性恋）女性的乳房X线摄影和巴氏试验数据。2003年6月至2005年6月在罗德岛招募了年龄在40 - 75岁的女性。她们被随机分配接受：自我管理邮寄问卷[SAMQ；N = 202]、计算机辅助电话访谈[CATI；N = 200]或计算机辅助自我访谈[CASI；N = 197]。计算逻辑回归模型，以评估与癌症筛查相关的13项自我报告项目的调查方式差异，并对年龄、教育程度、收入、种族、婚姻状况、伴侣性别和招募来源进行调整。
与被分配到CATI的女性相比，被分配到SAMQ的女性报告最近一次乳房X线摄影间隔两年或更长时间的可能性较小（CATI = 23.2% vs. SAMQ = 17.7%；调整后比值比[AOR] = 0.5，95%置信区间[CI] = 0.3 - 0.8），而被分配到CASI的女性报告乳房X线摄影逾期的可能性略小（CATI = 16.5% vs. CASI = 11.8%；AOR = 0.5，95% CI = 0.3 - 1.0）以及巴氏试验逾期的可能性略小（CATI = 14.9% vs. CASI = 10.0%；AOR = 0.5，95% CI = 0.2 - 1.0）。没有其他一致的方式效应。
在这个样本的参与者中，数据收集方式对乳房X线摄影和巴氏试验行为的报告影响很小。在确定用于监测癌症检测和控制指标的最合适数据收集形式时，还应考虑其他措施，如该方式的效率和成本效益。
