BACKGROUND The suitability of using reversed items in typical response measures has been a matter of controversy for many years. While some authors recommend their use, others reject them due to their undesirable effects on tests' psychometric properties. The present research intends to analyse a third alternative based on the use of reversed items plus a procedure to control response bias effects. METHOD We analysed two forms of the same test, one with direct and reversed items and another composed only of direct items, and compared them both before and after applying a procedure to control response biases. RESULTS The factorial structure and factorial reliability of both versions was almost equivalent after controlling response biases. When no effect biases were controlled, the version with both types of items exhibited less acceptable psychometric properties. CONCLUSIONS The use of reversed items is not advisable without the application of a procedure to control response bias effects. When such effects are mitigated, the results are equivalent to those obtained with only direct items, but with the added value of controlling for acquiescence effects.

推翻或不推翻李克特式项目:这就是问题所在。

背景技术多年来,在典型的应对措施中使用逆向项目的适用性一直是一个有争议的问题。尽管有些作者建议使用它们,但其他作者则拒绝使用它们,因为它们会对测试的心理计量特性产生不良影响。本研究旨在分析第三种替代方法,该方法基于使用反向项目以及控制响应偏差效果的过程。方法我们分析了同一测试的两种形式,一种由直接项目和反向项目组成,另一种仅由直接项目组成,并在应用程序控制响应偏差之前和之后对其进行了比较。结果在控制响应偏差后,两个版本的阶乘结构和阶乘可靠性几乎相等。当没有效果偏差得到控制时,带有两种类型物品的版本均显示出较差的心理测验特性。结论不建议使用逆向项目而不应用控制反应偏倚效应的程序。当减轻这种影响时,结果等同于仅使用直接项目获得的结果,但是具有控制默认效果的附加值。
