Given the central role for anxiety in psychosis, valid and reliable assessment is necessary. This systematic review is the first to critically appraise measures of anxiety applied to psychosis samples.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Web of Science, MEDLINE, PsycINFO, EMBASE, and CINAHL were systematically searched for studies evaluating psychometric properties of instruments measuring anxiety in samples with non\u2010affective psychosis diagnoses. Psychometric properties were extracted and rated according to established criteria. The COnsensus\u2010based Standards for the selection of health Measurement Instruments (COSMIN) checklist was used to assess the methodological quality of studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 4,344 records identified, 11 studies were identified as eligible for inclusion, by two independent raters with high reliability. Reported psychometric properties for 17 different instruments ranged from unacceptable to excellent. The Scale of Anxiety Evaluation in Schizophrenia was assessed most extensively and demonstrated consistently good psychometric properties. The Beck Anxiety Index, Depression Anxiety Stress Scale, DSM\u2010based Generalised Anxiety Disorder Symptoms Severity Scale, Liebowitz Social Anxiety Scale, Obsessive\u2013Compulsive Inventory, Psychological Stress Index, Perseverative Thinking Questionnaire, and Yale\u2010Brown Obsessive Compulsive Scale demonstrated adequate reliability and\/or validity on the limited properties reported. Methodological quality was largely poor according to the requirements of the COSMIN checklist.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The instruments listed are recommended as at least adequate for the assessment of anxiety in psychosis on the basis of these preliminary data.
