本研究检验了妊娠期糖尿病的自我报告与出生证明之间的一致性（一致性或收敛效度）。研究对象为2,854名早2-6个月活产的妇女，并对2004-2006年纽约州妊娠风险评估监测系统（PRAMS）调查问卷进行了回答。评估总体研究人群的自我报告和出生证明之间的一致性，以及按种族、年龄、教育程度、婚姻状况、以前活产的数量、首次产前护理的时间和新生儿出生体重定义的亚组。共有258名妇女自我报告患有妊娠糖尿病，而出生证明显示有138名妇女患有妊娠糖尿病。对于整个研究人群，一致性百分比为93.8%，Kappa为0.53。由于中等偏倚指数（总体为68.2%，亚组为33.3%至100%）和高偏倚患病率指数（总体为91.8%，亚组为70.7至97.5%），我们确定患病率调整和偏倚调整Kappa （PABAK）是更好的一致性衡量标准。PABAK总体为0.88，表明一致性非常好。在所有亚组中，PABAK都一致较高。25岁及以下女性的PABAK最高（0.93），亚洲女性最低（0.79）。虽然缺乏妊娠糖尿病的金标准阻碍了标准有效性的评估，但高PABAK测量表明，PRAMS受访者的自我报告对于确定妊娠糖尿病病例进行监测和基于人群的流行病学研究是可行的。
This study examined agreement (concordance or convergent validity) between self-report and birth certificate for gestational diabetes. Study population was 2,854 women who had live births 2-6 months earlier and responded to a questionnaire from the New York State Pregnancy Risk Assessment Monitoring System (PRAMS) survey, 2004-2006. Agreement between self-report and birth certificate was assessed for the study population overall, and for subgroups defined by race, age, education, marital status, number of previous live births, time of first prenatal care, and birth weight of the newborn. A total of 258 women self-reported gestational diabetes, while birth certificates indicated that 138 women had gestational diabetes. For the study population overall, percent agreement was 93.8% and Kappa was 0.53. Due to the moderate bias index (68.2% overall, ranged from 33.3 to 100% in subgroups) and the high skewed prevalence index (91.8% overall, ranged from 70.7 to 97.5% in subgroups), we determined Prevalence-Adjusted and Bias-Adjusted Kappa (PABAK) was a better measure of agreement. PABAK was 0.88 overall, indicating very good agreement. PABAK was uniformly high in all subgroups. The highest PABAK was found among women aged 25 years and younger (0.93), and the lowest PABAK was among Asian women (0.79). Although the absence of a gold standard for gestational diabetes hinders assessment of criterion validity, high PABAK measures suggest that self-reporting by PRAMS respondents is feasible for identifying cases of gestational diabetes for surveillance and population-based epidemiologic research.
