描述一种新的测量囊性纤维化(CF)妇女的生育保护(FP)知识的工具的开发、评估和心理测量学特性，该工具名为KFP-WCFI，名为KFP-WCFI。10个项目的KFP-WCFI是通过横断面调查编制和评估的。参与者是从CF基金会认可的CF诊所通过滚雪球抽样在全国范围内招募的。50名年龄在18岁到35岁之间的女性完成了这项测试。结构效度采用验证性因素分析(CFA)进行评估。在CFA中，使用标准化均方根残差(SRMR)、逼近均方根误差(RMSEA)和比较拟合指数(CFI)来评估模型拟合。采用克朗巴赫的α量表进行内部一致性信度检验。标准效度采用推论统计方法进行评估。“一般生育知识”和“与移植相关的生育知识”两个子量表的CFA与SRMR为0.07，RMSEA为0.06，CFI为0.07，表明该工具具有良好的结构效度。该仪器与Cronbachα的S的“一般生育知识”子量表的内部一致性信度为0.91，而“移植相关的生育知识”子量表的内部一致性信度为0.64。报告怀孕的女性得分高于没有报告怀孕的女性(p=0.02)，这表明标准的有效性。新开发的KFP-WCFI是一种有效和可靠的工具，可以用来测量患有CF的妇女的FP自我评估知识。一种新开发的仪器似乎是有效和可靠的衡量自我评估的知识，在囊性纤维化妇女的生育能力保留。
To describe the development, evaluation, and psychometric properties of a new instrument that measures fertility preservation (FP) knowledge in women with cystic fibrosis (CF) titled Knowledge of FP in Women with CF Instrument (KFP-WCFI). The 10-item KFP-WCFI was developed and evaluated through a cross-sectional survey. Participants were recruited nationally from CF Foundation-accredited CF clinics and via snowball sampling. Fifty women with CF ages 18 through 35 completed the instrument. Construct validity was assessed using confirmatory factor analysis (CFA). In the CFA, the model fit was evaluated using standardized root mean square residual (SRMR), root mean square error of approximation (RMSEA), and comparative fit index (CFI). Cronbach’s α was used to examine internal consistency reliability. The criterion validity was assessed using inferential statistics. The CFA with two subscales “General Fertility Knowledge” and “Transplant-related Fertility Knowledge” demonstrated good fit with SRMR of .07, RMSEA of .06, and CFI of .97, indicating good construct validity of the instrument. This instrument demonstrated internal consistency reliability with Cronbach α’s of .91 for the “General Fertility Knowledge” subscale, and .64 for the “Transplant-related Fertility Knowledge” subscale. Women who reported a pregnancy scored higher than women who did not report a pregnancy (p = .02) suggesting criterion validity. The newly developed KFP-WCFI appears to be a valid and reliable instrument that can be used to measure self-assessed FP knowledge in women with CF. A newly developed instrument appears to be valid and reliable for measuring self-assessed knowledge of fertility preservation in women with cystic fibrosis.
