Abstract：
BACKGROUND: A scale for self-assessment of auditory verbal hallucinations (SAVH) was developed for patients, and this study aimed to validate the scale by investigating its psychometric properties.
METHODS: Forty one patients with schizophrenia or schizoaffective disorders (DSM-5) self-assessed their hallucinations using nine SAVH questions. Each question was scored from 0 to 5, indicating the severity of the symptoms. Patients were also evaluated with the Brief Psychiatric Rating Scale (BPRS), Auditory Hallucination Rating Scale (AHRS), and Birchwood Insight Scale (BIS). The psychometric properties of the SAVH were assessed by the face, internal consistency, construct, convergent and discriminant validities.
RESULTS: SAVH scores were used to examine the psychometric properties. Cronbach\'s α and Guttman\'s Lambda-6 were 0.67 and 0.73 respectively. Significant correlations were observed between SAVH and AHRS total scores, as well as BPRS hallucinatory behavior subscores. No significant correlations were found between total SAVH scores and (i) levels of insight or (ii) negative BPRS subscores. Factor analysis on SAVH revealed three factors accounting for 59.3 % of the variance. Most patients found the questions clear, appropriate, and of adequate length.
CONCLUSIONS: SAVH demonstrated good psychometric properties, suggesting its utility in assessing auditory verbal hallucinations (AVH). This self-assessment could be valuable in evaluating AVH treatment efficacy, monitoring AVH, and empowering patients.

摘要：
背景：为患者开发了听觉言语幻觉自我评估量表（SAVH），本研究旨在通过调查其心理测量学特性来验证该量表。
方法：41名精神分裂症或分裂情感障碍（DSM-5）患者使用9个SAVH问题自我评估幻觉。每个问题的评分从0到5，表明症状的严重程度。患者也用简短精神病学评定量表（BPRS）进行评估，听觉幻觉评定量表(AHRS),和伯奇伍德洞察量表(BIS)。通过面部评估SAVH的心理测量特性，内部一致性，construct,收敛和判别效价。
结果：SAVH评分用于检查心理测量特性。克朗巴赫α和古特曼λ-6分别为0.67和0.73。在SAVH和AHRS总分之间观察到显着的相关性，以及BPRS幻觉行为子评分。在总SAVH评分与(i)洞察力水平或(ii)阴性BPRS子评分之间没有发现显著相关性。对SAVH的因子分析显示三个因素占方差的59.3%。大多数患者发现问题很清楚，适当，有足够的长度。
结论：SAVH表现出良好的心理测量特性，表明其在评估听觉言语幻觉（AVH）中的实用性。这种自我评估在评估AVH治疗效果方面可能是有价值的，监测AVH,赋予患者权力。
