Despite a steep rise in the evidence base for third-wave cognitive and behavioural therapy approaches over the past decade, a scarcity of change measures relevant to these therapies as applied to psychosis is arguably slowing empirical progress in the area. The Voices Acceptance and Action Scale (VAAS), a measure of acceptance of voice experiences, is a notable exception. However, there are no published data on its psychometric properties outside of that provided by the scale developers. The current study explored the psychometric properties of two brief versions of the VAAS in a sample of psychotic voice hearers in a routine outpatient mental health service. Evidence from the current study suggests that both brief versions are robust measures of acceptance of voice experiences. Some limited support for the shortened VAAS-9 as being a marginally improved scale over the original brief VAAS-12 was also found. The current study found acceptance of voices to be highly related to depression, anxiety, stress and general negative affect and to predict unique variance in depression and general negative affect beyond that attributable to negative beliefs about voices and thought suppression. It was also found that acceptance was positively related to the use of reappraisal, indicating that the distinctiveness of acceptance from appraisal processes may be less pronounced in this context than what was has been reported previously. Implications for future research, as well as the practice of second-wave and third-wave cognitive and behavioural approaches to psychosis, are discussed.
Two brief versions of the VAAS instrument were found to be robust measures of acceptance of psychotic voice experiences. The construct of acceptance of voices is highly related to indices of well-being and negative appraisal processes in psychosis and appears to offer an alternative route to therapeutically addressing the toxic effects of negative beliefs about voices. The recent focus on acceptance-based techniques within cognitive and behavioural approaches to psychosis was supported.
尽管在过去十年中，第三波认知和行为疗法的证据基础急剧增加，但应用于精神病的与这些疗法相关的改变测量方法的稀缺，可能正在减缓该领域的实证进展。声音接纳与行动量表（VAAS）是一种衡量对幻听体验接纳程度的量表，是一个显著的例外。然而，除了量表开发者提供的数据外，没有关于其心理测量特性的已发表数据。本研究在一家常规门诊心理健康服务机构的精神病性幻听患者样本中，探讨了VAAS两个简短版本的心理测量特性。本研究的证据表明，两个简短版本都是对幻听体验接纳程度的可靠测量方法。还发现了一些有限的证据支持缩短后的VAAS-9比原始简短的VAAS-12略有改进。本研究发现，对幻听的接纳与抑郁、焦虑、压力和一般负面情绪高度相关，并能预测抑郁和一般负面情绪中超出因对幻听的负面信念和思维抑制所致的独特变异。还发现接纳与重新评价的使用呈正相关，这表明在这种情况下，接纳与评价过程的区别可能不如先前报道的那么明显。讨论了对未来研究以及第二波和第三波精神病认知和行为疗法实践的启示。
发现VAAS工具的两个简短版本是对精神病性幻听体验接纳程度的可靠测量方法。对幻听的接纳结构与精神病中的幸福感指标和负面评价过程高度相关，似乎为治疗性解决对幻听的负面信念的毒性影响提供了一条替代途径。支持了最近在精神病认知和行为疗法中对基于接纳的技术的关注。
