Responses to positively and negatively worded items are not always consistent, a behavioral pattern known as the item valence method effect. The current research employed latent difference (LD) modeling (Pohl, Steyer, & Kraus, 2008 ) to help determine explanations of the method effect. Respondents were more likely to reject negative characteristics (measured by negatively worded items) than to accept positive ones (measured by positively worded items), and supplementary analysis showed that this tendency was associated with social desirability response style. Correlations between the method effect and social desirability varied across Big Five personality traits, implying that social desirability cannot be the sole reason behind the phenomenon. Other possible explanations are discussed.
正向和负向题目的反应并不总是一致的，这种行为模式被称为项目效价方法效应。当前的研究采用潜在差异（LD）建模（Pohl、Steyer 和 Kraus，2008）来帮助确定方法效应的解释。与接受积极特征（通过正向表述项目衡量）相比，受访者更有可能拒绝消极特征（通过负向表述项目衡量），补充分析表明这种趋势与社会期望反应模式有关。方法效应与社会期望之间的相关性因五大人格特质而异，这意味着社会期望不能成为这一现象的唯一原因。还讨论了其他可能的解释。
