摘要

持續性注意力是精神分裂症患者生活以及工作之關鍵能力，且與患者之復健相關。研究及臨床人員欲探究或介入持續性注意力，皆須具良好心理計量特性之測驗。然而目前較少研究彙整適用於精神分裂症患者之持續性注意力評估工具，及各持續性注意力評估工具之心理計量特性評析，故本研究回顧近六年內常用於精神分裂症隨機控制驗證研究之持續性注意力評估工具，並彙整其用於精神分裂症患者之心理計量特性（含信度、效度、反應性及最小重要差異值）。研究者合併檢索中、英文之電子期刊資料庫，找出2007至2013年間較常用（被使用2次以上）於精神分裂症隨機控制驗證研究之持續性注意力評估工具。再比較這些測驗應用於精神分裂症患者之心理計量特性。常用於精神分裂症隨機控制驗證研究之持續性注意力評估工具共計三種：Continuous Performance Test-Identical Pairs（CPT-IP）、Conners' Continuous Performance Test（CCPT）及Rapid Visual Information Processing Task（RVIP）。上述測驗針對精神分裂症患者之心理計量特性驗證結果如下：CPT-IP再測信度中等至良好，但缺乏其它心理計量特性驗證。CCPT之收斂效度及區辨效度不佳，且缺乏其它心理計量特性驗證。未有研究驗證RVIP之心理計量特性。回顧結果顯示常用於精神分裂症隨機控制驗證研究之持續性注意力評估工具欠缺充份之心理計量特性驗證。

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.
