<p> This study meta-analyzed IRT item discrimination parameter estimates and CFA item loadings to explore the methodological effect of negatively-worded items in personality measures. We found three important moderators that determined whether the negatively-worded item effect affected a scale. The first moderator was the manner in which the scale was defined. We found a strong negatively-worded item effect for <i>Neuroticism</i> but not for <i>Emotional Stability</i>. The personality scale was also a moderator, with a negatively-worded item effect being observed for <i>Agreeableness, Extraversion, Neuroticism, </i> and <i>Openness</i> but a positively-worded item effect for <i>Emotional Stability</i> and <i>Conscientiousness</i>. Third, low-motivation samples tended to produce a larger negatively-worded item effect. Moreover, there was no statistically significant difference between personality and non-personality inventories regarding the negatively-worded item effect. Finally, item negation did not produce the expected effect. Practical implications and limitations of the study are discussed.</p>
