精神病与主观性增加、内分泌和自主神经系统应激反应改变有关。精神病患者经常经历听觉语言幻觉，负面声音内容尤其与痛苦有关。本研究开发了语音模拟范式，考察了中性和负性内容的模拟声音对心理生理应激反应的影响，以及有意识的声音评价对应激反应的影响。84名健康参与者完成了蒙特利尔成像压力任务，同时呈现了三种随机分配的听觉刺激条件之一：消极声音、中性声音或非声音环境声音。主观压力水平和专注的声音评估使用问卷测量，皮质醇和α-淀粉酶水平使用唾液样本测量。方差分析显示，条件对主观压力水平有显著影响(p = .002)，但皮质醇(p = .63)或α-淀粉酶(p = .73)无显著影响。事后分析表明，相对于中性声音(p = .002)和环境声音(p = .01)，负面声音增加了主观压力水平，这两种声音彼此没有区别(p = .41)。有意识的声音评估与不同情况下较少的痛苦有关(p = .003)，尽管负面的声音也与不太有意识的评估有关(p <； .001)。负面的声音内容，而不是声音或听觉刺激本身，与更大的主观压力反应有关，但与生理压力反应无关。谨慎的评估可能会在一定程度上缓解这种影响。这些发现突出了声音内容对声音听力影响的重要性，并突出了正念训练在治疗精神病患者声音苦恼方面的潜在价值。
Psychosis is associated with increased subjective and altered endocrine and autonomic nervous system stress-reactivity. Psychosis patients often experience auditory verbal hallucinations, with negative voice content being particularly associated with distress. The present study developed a voice-simulation paradigm and investigated the effect of simulated voices with neutral and negative content on psychophysiological stress-reactivity, and the effect of mindful voice-appraisals on stress-reactivity. Eighty-four healthy participants completed the Montreal Imaging Stress Task with simultaneous presentation of one of three randomly allocated auditory stimuli conditions: negative voices, neutral voices or non-voice ambient sounds. Subjective stress-levels and mindful voice-appraisals were assessed using questionnaire measures, and cortisol and α-amylase levels were measured using saliva samples. ANOVA revealed a significant effect of condition on subjective stress-levels (p = .002), but not cortisol (p = .63) or α-amylase (p = .73). Post-hoc analyses showed that negative voices increased subjective stress-levels relative to neutral voices (p = .002) and ambient sounds (p = .01), which did not differ from each other (p = .41). Mindful voice-appraisals were associated with less distress across conditions (p = .003), although negative voices were also associated with less mindful appraisals (p < .001). Negative voice content, rather than voices or auditory stimuli per se, is linked to greater subjective but not physiological stress-reactivity. Mindful appraisals may partially moderate this effect. These findings highlight the importance of voice content for the impact of voice-hearing, and highlight the potential value of mindfulness training to treat voice distress in psychosis.
