目标。这是前列腺癌结局研究（PCOS）中的一项辅助方法学研究，旨在评估诊断为前列腺癌的男性患者诊断前疾病靶向功能的6个月回顾性召回的有效性。133例前列腺癌患者在诊断后不久进行了基线问卷调查，询问了诊断前的泌尿、性功能和肠道功能。6个月后，他们再次就相同的项目进行了调查，并被要求回忆他们的预诊断功能。在基线和6个月时获得的诊断前功能报告进行比较，以及从这些报告中得出的变化措施。计算一致性百分比和加权kappa来衡量一致性的程度。超过70%的男性在17项调查中有12项的诊断前功能达到了最高水平。对于这些项目中的每一个，6个月时的回忆与基线调查反应相同，大于或等于69%的男性。基线报告计算的变化（前瞻性）和6个月回忆（回顾性）计算的变化的加权kappas值在17个单独项目的0.396至0.919之间。多项功能评分的回顾性与前瞻性变化的类内相关性为：尿功能为0.828，肠功能为0.618，性功能为0.692。在基线上，最近被诊断为前列腺癌的男性在诊断前很少报告与疾病相关的问题，而且6个月后准确回忆起这一点的男性比例很高。在基线和6个月的预诊断功能估计之间，以及在6个月的前瞻性和回顾性变化测量之间，存在相当高的一致性。
OBJECTIVES. This was an ancillary methodological study within the Prostate Cancer Outcomes Study (PCOS) to assess the validity of 6-month retrospective recall of prediagnostic disease-targeted function among men diagnosed with prostate cancer.METHODS. A convenience sample of 133 prostate cancer cases were administered a baseline questionnaire shortly after diagnosis that asked about prediagnostic urinary, sexual, and bowel function. They were surveyed again concerning the same items 6 months later and asked to recall their prediagnostic function. Reports of prediagnostic function obtained at baseline and 6 months are compared, as are measures of change derived from these reports. Percent agreement and weighted kappas are calculated to measure the extent of agreement.RESULTS. Over 70% of the men reported prediagnostic functioning at the highest level on 12 of 17 survey items. For each of these items, recall at 6 months was identical to the baseline survey response for greater than or equal to 69% of the men. The values of the weighted kappas for changes computed with baseline reports (prospective) and changes computed with 6-month recall (retrospective) ranged from 0.396 to 0.919 for the 17 individual items. Intraclass correlations for the retrospective versus prospective changes in the multi-item function scores were 0.828 for urinary, 0.618 for bowel, and 0.692 for sexual function.CONCLUSIONS. At baseline, men recently diagnosed with prostate cancer report few disease-related problems before diagnosis, and a high percentage of men recall this accurately 6 months later. There is reasonably high agreement between baseline and 6-month estimates of prediagnostic function and between prospective and retrospective measures of change over 6 months.
