自知力评定量表中文版的信效度研究

Reliability and validity of the Chinese version of the schedule for assessment of insight

目的 探讨自知力评定量表（SAI）中文版的信度和效度.方法 将原版量表进行翻译、回译,形成SAI中文版,对220例符合精神障碍诊断和统计手册第四版（DSM-Ⅳ）精神分裂症、精神分裂症样障碍、分裂情感性精神障碍、妄想性精神障碍、短暂精神病性障碍诊断标准的患者进行了施测,并做信度和效度检验.结果 总量表的标准化Cronbach＇sα系数为0.890,重测信度为0.742,评估者间一致性为0.986.该量表包含三个分量表：疾病意识、精神症状标识及治疗依从性.各条目对因子的负荷系数为0.883 ～0.944.总量表及三个分量表与PANSS自知力评分的相关系数分别为-0.635,-0.305,-0.631及-0.512（P＜0.01）.结论 自知力评定量表中文版具有良好的信度和效度.

Objective To investigate reliability and validity of the Chinese version of the schedule for assessment of insight （SAI）.Methods The original version of SAI was translated into Chinese and then backtranslated into English to develop the Chinese version of SAI which reliability and validity were tested.220 subjects who met the diagnosis of Schizophrenia,schizophreniform disorder,schizoaffective disorder,delusional disorder or brief psychotic disorder were assessed.Results The Cronbach＇s α was 0.890 ; the test-retest reliability was 0.742 ; the inter-rater reliability was 0.986.Three main factors were obtained from the factor load matrix as awareness of illness,ability to relabel psychotic experience,compliance with treatment.The loading coefficient were 0.883-0.944.The correlation of the SAI total score and three subscales with insight of PANSS were-0.635,-0.305,-0.631 and-0.512 respectively （P 〈 0.01）.Conclusion The SAI has good reliability and validity.The scale is useful to measure insight in psychosis.
