Clinicians must be able to identify the presence, characteristics, and severity of USN using psychometrically sound assessments. Virtual reality offers a standardized and rapid means of assessing for USN in a safe and controlled environment. Enabled by advances in technology, this study established the validity of a new, immersive version of a prior validated, reliable, and sensitive assessment tool, the Virtual Reality Lateralized Attention Test (VRLAT). This new version (VRLAT\u20102) is novel because it uses a head\u2010mounted display to provide an immersive and more realistic experience where participants are free to turn their heads while participating.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To examine the concurrent and discriminant validity of the immersive VRLAT\u20102 and to establish a preliminary cutoff score for determining USN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Criterion standard.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Setting<\/jats:title>\n                    <jats:p>Institutional laboratory.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Participants<\/jats:title>\n                    <jats:p>37 adults with right hemisphere stroke and 16 age\u2010matched neurotypical individuals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interventions<\/jats:title>\n                    <jats:p>Not applicable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main Outcome Measures<\/jats:title>\n                    <jats:p>The primary outcome measure was the VRLAT\u20102.
