The Clinical Global Impression-Corrections (CGI-C) is an adaptation of the severity scale of the Clinical Global Impression for use in correctional facilities. Although it has been shown to have good inter-rater reliability, there have been no validation studies of this instrument. We analyzed data from 726 initial assessments of persons detained in two correctional facilities and compared clinician's ratings for the CGI-C and modified Brief Psychiatric Rating Scale-Expanded (BPRS-E). We used equipercentile linkage and Spearman correlations to investigate concordance in the total sample, by diagnostic groups, and by gender. We found that the CGI-C scores and BPRS-E scores among persons in remand settings were significantly correlated (ρ = 0.51, < 0.001) and that correlations were the same for men and women. We found that points of equivalence can be reliably found between the two scales using equipercentile linkage, and that those with psychotic disorders had lower BPRS-E scores than those with mood/anxiety/situational stress for equivalent CGI-C scores. Overall, CGI-C ratings correspond well to BPRS-E ratings for both men and women remand prisoners across diagnoses, and the CGI-C appears to be a valid tool for the assessment of severity of symptoms in this setting.
临床总体印象-校正版（CGI-C）是对临床总体印象严重程度量表的一种改编，用于惩教机构。尽管已证明它具有良好的评分者间信度，但尚未对该工具进行效度研究。我们分析了来自两个惩教机构中726名被拘留者的初次评估数据，并比较了临床医生对CGI-C和改良简明精神病评定量表扩展版（BPRS-E）的评分。我们使用等百分位关联法和斯皮尔曼相关性来研究总样本、诊断组和性别的一致性。我们发现，还押候审人员的CGI-C得分与BPRS-E得分显著相关（ρ = 0.51，<0.001），且男性和女性的相关性相同。我们发现，使用等百分位关联法可以在两个量表之间可靠地找到等效点，并且在等效的CGI-C得分下，患有精神障碍的人BPRS-E得分低于患有情绪/焦虑/情境性应激障碍的人。总体而言，CGI-C评分与还押候审的男性和女性囚犯在所有诊断中的BPRS-E评分都非常吻合，并且CGI-C似乎是评估该环境中症状严重程度的有效工具。
