摘　　要：目的 :探讨验证问卷备择答案等距离性的方法。方法 :计算去除某条目后 ,同领域其他条目得分的合计值 ,然后观察选择该条目不同备择答案的人群 ,其合计值间是否等距离。测试量表采用 3 6条目简明量表 ,调查样本 2 2 5 0人 ,纳入分析样本 2 2 46例。结果 :使用该法能够发现问卷中的异常条目 ,等距离性验证结果与原量表设计基本吻合 ,但是测试条目必须具有较好的结构效度。结论 :同领域条目相互验证可能是验证备择答案的等距离性的一种简易方法 ,对此尚需数理学论证。Objectives:To investigate appropriate approach of testing the interval feature of alternative answers in questionnaires.Methods:We calculated the total scores of the items within the same domain excluding the item that was under test, and then, identified the distances between the scores of the population who chose the different alternative answers of the test item. The short form 36 was used in the test. We surveyed a total of 2250 residents, with 2246 included in the final analysis.Results:This approach could find the deviated item in the questionnaire. The results of testing of the interval feature of alternative answers were consistent with the original design; however, the clustered items must have good construct validity.Conclusion:Using the items clustered in one domain to test the interval feature of alternative answers may possibly be an available simple approach, but we need more mathematics evidence to prove this assumption.
