Due to the length and inconsistent factor structure of the IUS\u201012, an abbreviated version consisting of five items (IUS\u20105) has been proposed. However, no study has examined its psychometric properties aside from the preliminary work by its developers. The current study investigated the factor structure of the IUS\u20105 as well as its reliability and validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>A sample of 315 nurses completed an online self\u2010report questionnaire during the COVID\u201019 pandemic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Confirmatory factor analysis of the IUS\u20105 suggested a deletion of one item. The final analysis supported a one\u2010factor solution on the remaining four items (IUS\u20104) with a McDonald's omega of 0.77. The validity of IUS\u20104 was assessed by testing its positive and negative correlations with existing related and contrary measures, respectively. Further, the validity of the IUS\u20104 was supported through known\u2010group validation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This is the first psychometric assessment of the IUS\u20105 measure of intolerance of uncertainty in a sample of nurses. Results from the current study supported a shorter measure of four items. However, more work needs to be conducted to examine the IUS\u20104 and IUS\u20105 in samples of healthcare providers with different cultural and linguistic backgrounds.<\/jats:p>\n
