Voice power is an important concept in daily life of voice hearers and in the support and therapy for voice hearers who seek help. Therefore, the ability to examine voice power differentials between a voice and a voice hearer is essential. The present study aimed to collect data on voice power differentials and to further validate the Voice Power Differential Scale (VPD). 105 participants aged ≥ 18 with an ICD10 F2-diagnosis that included hearing voices were included in this study. Internal consistency was good (alpha = 0.792), as well as test-retest-reliability (r = 0.855) and correlations with other constructs were generally as expected. The VPD questionnaire results correlated negatively with the Beliefs About Voices Questionnaire-Revised's (BAVQ-R) items of Benevolence and Engagement-emotion. It correlated positively with Omnipotence and Resistance-emotion, as well as with Negative Content on the Psychotic Symptoms Rating-Scale (PSYRATS). Unexpectedly, no correlations were found with overall severity and command hallucinations. The Voice Power Differential Scale is an important tool for assessing and formulating a voice hearer's experience when they seek treatment or support for their verbal auditory hallucinations. The results of this study enrich the on-going discussion about the importance of voice power for voice hearers.
声音力量是声音使用者日常生活以及寻求声音使用者支持和治疗的重要概念。因此，检查声音与声音使用者之间声音力量差异的能力至关重要。本研究旨在收集声音力量差异的数据，并进一步验证声音力量差异量表（VPD）。本研究纳入了 105 名年龄≥18 岁、符合 ICD10 F2 诊断标准且存在幻听的参与者。内部一致性良好（α=0.792），重测信度（r=0.855）以及与其他结构的相关性通常符合预期。VPD 问卷结果与经过修订的幻听信念问卷（BAVQ-R）中的仁慈和参与-情绪项目呈负相关，与全能和反抗-情绪以及精神病症状评定量表（PSYRATS）的负性内容呈正相关。出乎意料的是，与总体严重程度和命令性幻觉没有相关性。声音力量差异量表是评估和制定声音使用者在寻求治疗或支持其言语性幻听时体验的重要工具。本研究的结果丰富了关于声音力量对声音使用者重要性的持续讨论。
