Inattention in people with schizophrenia is common. However, there has been little research on the association between inattention and auditory hallucinations. The aim of the study was to investigate how inattention is affected by beliefs about voices as benevolent and malevolent and perceived control of voices. A total of 31 patients who experienced auditory hallucinations and who met the criteria for schizophrenia or other psychosis completed the attention subscale of the Scale for the Assessment of Negative Symptoms (SANS) and the Connors' Continuous Performance Test II (CCPT-II). The revised Beliefs About Voices Questionnaire (BAVQ-R) was used to assess malevolent and benevolent beliefs about voices, and severity of auditory hallucinations (the Psychotic Symptom Rating Scales; PSYRATS) was used to assess perceived control of voices and frequency of voices. Levels of depression (the Beck Depression Inventory; BDI), anxiety (the Beck Anxiety Inventory; BAI), severity of overall psychiatric symptoms (the Brief Psychiatric Rating Scale; BPRS), and severity of negative symptoms (SANS) were assessed to control for their potential confounding effects. The relations between the variables were explored with correlations and multiple hierarchical regression analyses. The results indicated that more malevolent, but not more benevolent, beliefs about voices predicted lower levels of attention, independently of general psychiatric symptoms and various other psychotic symptoms such as frequency of and perceived control of voices. These findings suggest an important relationship between malevolent beliefs about voices and levels of inattention. The possible impact of changing beliefs about voices to improve attentional functioning is discussed.
精神分裂症患者普遍存在注意力不集中的问题。然而,关于注意力不集中与幻听之间的关联,研究甚少。本研究旨在调查对声音的信念(即声音是仁慈的还是恶意的)以及对声音的感知控制,如何影响注意力不集中。共有 31 名经历过幻听且符合精神分裂症或其他精神病诊断标准的患者,完成了阴性症状评定量表(SANS)的注意力分量表和康纳斯连续操作测验第二版(CCPT-II)。采用修订后的声音信念问卷(BAVQ-R)评估对声音的恶意和仁慈信念,采用幻听严重程度评定量表(PSYRATS)评估对声音的感知控制和声音频率。采用贝克抑郁量表(BDI)、贝克焦虑量表(BAI)评估抑郁和焦虑水平,采用简明精神病评定量表(BPRS)评估总体精神病严重程度,采用阴性症状评定量表(SANS)评估阴性症状严重程度,以控制其潜在的混杂效应。通过相关性分析和多元层次回归分析探讨了变量之间的关系。结果表明,对声音的信念越恶意,但不越仁慈,与注意力水平越低独立相关,而与一般精神病症状和其他各种精神病症状(如声音的频率和感知控制)无关。这些发现表明,对声音的恶意信念与注意力不集中水平之间存在重要关系。讨论了改变对声音的信念以改善注意力功能的可能性。
