To describe and compare the intra- and interexaminer reliability of head circumference measurements obtained with paper and cloth tape measures.
Two experienced neonatal nurses each obtained head circumference measurements using both paper and cloth tape measures twice each, from 49 clinically stable, preterm infants. The nurses were blind to their own and to each other's measurements. The order in which the measurements were obtained was randomized. The differences within and between examiners for cloth and paper tape measurements were described using mean absolute differences, standard deviation of net differences, technical error of measurement, minimal and maximal differences, percentage of differences 0.25 and 0.5 cm, and percentage of error.
Wilcoxon matched-pairs, signed-ranks tests demonstrated significantly greater intraexaminer reliability for measurements obtained with the paper tape for both of the nurses. Wilcoxon matched-pairs, signed-ranks tests also demonstrated significantly greater interexaminer reliability for measurements obtained with the paper tape for both the first and second measurement sets.
Intra- and interexaminer differences were consistently smaller when the examiners used paper tape measures.
描述并比较使用纸质卷尺和布质卷尺测量头围时检查者内及检查者间的可靠性。
两名经验丰富的新生儿护士分别使用纸质卷尺和布质卷尺，对49名临床状况稳定的早产儿各测量两次头围。护士们对自己和彼此的测量结果均不知情。测量顺序随机安排。使用平均绝对差值、净差值标准差、测量技术误差、最小和最大差值、0.25厘米和0.5厘米差值的百分比以及误差百分比来描述布质卷尺和纸质卷尺测量时检查者内及检查者间的差异。
威尔科克森配对符号秩检验表明，两名护士使用纸质卷尺测量时，检查者内可靠性均显著更高。威尔科克森配对符号秩检验还表明，对于第一组和第二组测量，使用纸质卷尺测量时检查者间可靠性也显著更高。
当检查者使用纸质卷尺测量时，检查者内及检查者间的差异始终较小。
