Uncertainty is an aversive experience and plays an important role in the lives of men undergoing active surveillance (AS; earlier referred to as watchful waiting) for early-stage prostate cancer. Yet reliable and valid measures of uncertainty have not been fully tested in this population. This secondary analysis therefore tested the reliability of the Mishel Uncertainty in Illness Scale Community Form (MUIS-C; M.H. Mishel, 1997b) for use with men undergoing AS for prostate cancer.
Item-Total correlations were conducted on the 23 items of the MUIS-C with four samples of men undergoing AS.
Cronbach's alpha for the full MUIS-C was .908; 22 of 23 items showed significant positive correlations with the total score. Removing the item without a significant correlation from the reliability analysis increased Cronbach's alpha to .913.
The Mishel Uncertainty in Illness Scale-Community Form for Active Surveillance is a reliable and valid tool for measuring uncertainty with men undergoing AS for prostate cancer.
不确定性是一种令人厌恶的体验,在接受主动监测(AS;以前称为观察等待)早期前列腺癌的男性生活中起着重要作用。然而,在这一人群中,尚未充分测试可靠且有效的不确定性测量方法。因此,这项二次分析测试了米舍尔疾病不确定感量表社区版(MUIS-C;M.H. Mishel,1997b)在接受前列腺癌 AS 男性中的可靠性。
对四个接受 AS 的男性样本进行了 MUIS-C 的 23 个项目的项目-总分相关性分析。
MUIS-C 的克朗巴赫系数为.908;23 个项目中的 22 个与总分呈显著正相关。从可靠性分析中删除无显著相关性的项目后,克朗巴赫系数增加到.913。
米舍尔疾病不确定感量表-社区版用于主动监测是一种可靠有效的工具,可用于衡量接受前列腺癌 AS 男性的不确定性。
