Investigation of the two-factor model for the English version of the need for closure scale

Using the English version of the Need for Closure Scale, this research investigated previous, though largely ignored, recommendations to exclude the close-mindedness subscale and to treat the Need for Closure Scale as a two-factor (vs single-factor) scale. Reliability and correlational analyses supported the recommendation to exclude close-mindedness. The two-factor model without close-mindedness yielded better fit indexes than a single-factor model or a two-factor model with close-mindedness. Despite the strong cross-cultural use of the scale, no investigation had yet tested the two-factor model without close-mindedness using any language other than Dutch. The present results and discussion can improve the study of need for closure by encouraging more researchers to consider the supported recommendations. Roets and Van Hiel's proposed modification to make the Need for Closure Scale a single-factor scale was also discussed.
