Observers differ in their judgment while assessing physical signs in a patient. We had undertaken a goitre prevalence survey amongst school students in a Rural Health Training Centre, Pune district (Maharashtra) during October 1992. Four teams of trained observers were used for detection of goitre. This study was undertaken to estimate the extent and acceptability of interobserver agreement amongst the four teams. Observer variation/agreement was measured by two methods viz. kappa coefficient and proportion of agreement. The proportion of agreement appears to be a better measure of observer agreement as it could make a distinction between normality (absence of goitre) and abnormality (presence of goitre). In the present study, the proportion of agreement for abnormality ranged between 0.62 - 0.83. This measure was considered as indicating a good interobserver agreement in detecting goitre in the survey that was undertaken.
在评估患者的体征时，观察者的判断存在差异。1992年10月，我们在马哈拉施特拉邦浦那区的一个农村卫生培训中心对在校学生进行了一项甲状腺肿患病率调查。使用了四组经过培训的观察者来检测甲状腺肿。本研究旨在评估这四组观察者之间观察者间一致性的程度和可接受性。观察者变异/一致性通过两种方法进行测量，即kappa系数和一致性比例。一致性比例似乎是衡量观察者一致性的更好指标，因为它可以区分正常情况（无甲状腺肿）和异常情况（有甲状腺肿）。在本研究中，异常情况的一致性比例在0.62至0.83之间。在本次调查中，该指标被认为表明在检测甲状腺肿方面观察者间一致性良好。
