临床总体印象量表（CGI）是精神病学研究的核心指标。本研究的目的是测试CGI作为一个临床结果的措施，适合在私人住院settings. CGI常规使用的有效性被添加到一个标准电池的常规结果的措施，在一家私人精神病医院。收集了24个月内连续入院的数据，其中包括临床诊断，人口统计学，服务利用和四个常规措施（CGI，HoNOS，MHQ-14和DASS-21）在入院和出院。在786例住院患者中，分别有624例和614例在入院和出院时完成了CGI-S评分，610例完成了CGI-I评分。入院和出院CGI-S评分相关（r = 0.40），从其差异中获得的间接改善措施与直接CGI-I评分高度相关（r = 0.71）。CGI结果反映了其他三种结局指标的相似趋势，CGI是一种有效的临床结局指标，适合在住院患者中常规使用。它提供了许多优势，包括其在精神病学研究中的既定效用，对变化的敏感性，快速和简单的管理，跨诊断组的效用，以及熟练的临床医生手中的可靠性。
The Clinical Global Impression Scale (CGI) is established as a core metric in psychiatric research. This study aims to test the validity of CGI as a clinical outcome measure suitable for routine use in a private inpatient setting.The CGI was added to a standard battery of routine outcome measures in a private psychiatric hospital. Data were collected on consecutive admissions over a period of 24 months, which included clinical diagnosis, demographics, service utilization and four routine measures (CGI, HoNOS, MHQ-14 and DASS-21) at both admission and discharge. Descriptive and comparative data analyses were performed.Of 786 admissions in total, there were 624 and 614 CGI-S ratings completed at the point of admission and discharge, respectively, and 610 completed CGI-I ratings. The admission and discharge CGI-S scores were correlated (r = 0.40), and the indirect improvement measures obtained from their differences were highly correlated with the direct CGI-I scores (r = 0.71). The CGI results reflected similar trends seen in the other three outcome measures.The CGI is a valid clinical outcome measure suitable for routine use in an inpatient setting. It offers a number of advantages, including its established utility in psychiatric research, sensitivity to change, quick and simple administration, utility across diagnostic groupings, and reliability in the hands of skilled clinicians.
