Sustained attention is significantly correlated with community function and psychosocial sills for patients with schizophrenia. Selecting and using sustained attention tests with sound psychometric properties to assess patients with schizophrenia is important to identify the problems of attention. The purpose of this study is to review and appraise the psychometric properties of sustained attention tests that were used in randomized controlled trials of schizophrenia published in 2007-2013. This study included two parts. In the first part, four databases (MEDLINE, PsycINFO, CINAHL, and Index to Taiwan Periodical Literature System) were searched to identify sustained attention tests frequently used in randomized controlled trials in 2007-2013. Second, a search was conducted for psychometric properties (reliability, validity, and responsiveness) of identified sustained attention tests in patients with schizophrenia. Three frequently used (i.e. used more than twice) sustained attention tests were the Continuous Performance Test-Identical Pairs (CPT-IP), the Conners Continuous Performance Test (CCPT), and the Rapid Visual Information Processing Task (RVIP). The test-retest reliability of the CPT-IP in patients with schizophrenia was moderate to high, but the validity and the responsiveness of the CPT-IP in patients with schizophrenia were not obtained. The convergent validity and the discriminant validity of the CCPT in patients with schizophrenia were not satisfactory, and the reliability and the responsiveness of the CCPT in patients with schizophrenia had not been fully examined. No specific studies of psychometric properties of the RVIP in patients with schizophrenia were found in the literature. Most of the psychometric properties of these three sustained attention tests in patients with schizophrenia had rarely been examined.
