摘要

背景:神经性厌食症(AN)患者对自己的状况表现出特殊的洞察力障碍,通常表现为否认极度消瘦,有时还隐瞒或少报社会上不受欢迎的异常饮食模式。有时AN患者的信念强度达到妄想强度。目的:在这项研究中,将意大利版的尼泊尔信念量表应用于诊断为AN的患者样本,以调查他们的信念和信念的强度及其临床相关性。方法:根据DSM-5结构化临床访谈(SCID-5),将Nepean信念量表(NBS)翻译成意大利语并应用于AN患者样本。收敛有效性通过与《饮食障碍洞察力评估表》测量的洞察力水平的负相关来证明。10%的参与者报告了妄想强度的信念。那些信念强度更大的人,无论是被高估还是妄想,更有可能在蒙特利尔认知评估中报告较差的一般认知表现。NBS评分与年龄、体重指数、饮食失调症状、身体不满意或抑郁水平之间没有关联。对体重增加的恐惧和寻求控制是国家统计局最常报道的主题。结论:意大利版的国家统计局是一个合理可靠、有效和可用的工具,用于对AN的洞察力进行多维评估。证据水平III级,从精心设计的队列或病例对照分析研究中获得的证据。

The Nepean Belief Scale (NBS) as a tool to investigate the intensity of beliefs in anorexia nervosa: psychometric properties of the Italian version.

Background: People with anorexia nervosa (AN) show a peculiar impairment of insight regarding their condition, often manifesting a denial of extreme emaciation and sometimes hiding or underreporting socially undesirable abnormal eating patterns. Sometimes the intensity of the beliefs held by patients with AN reach a delusional intensity.

Objectives: In this study, the Italian version of the Nepean Belief Scale was applied to a sample of patients diagnosed with AN to investigate the intensity of their beliefs and convictions and its clinical correlates.

Methods: The Nepean Belief Scale (NBS) was translated and adapted to Italian and applied to a sample of patients diagnosed with AN based on the Structured Clinical Interview for DSM-5 (SCID-5).

Results: The Italian version of the 5-item NBS showed excellent reliability. Convergent validity was proved by negative association with levels of insight measured with the Schedule for the Assessment of Insight in Eating Disorders. Beliefs of delusional intensity were reported by 10% of participants. Those with a greater intensity of beliefs, either overvalued or delusional ideas, were more likely to report poorer general cognitive performances on the Montreal Cognitive Assessment. No association was observed between NBS score and age, body mass index, symptoms of eating disorders, body dissatisfaction, or levels of depression. Fear of weight gain and control seeking were the most often reported themes at the NBS.

Conclusions: The Italian version of the NBS is a reasonably reliable, valid, and usable tool for the multidimensional assessment of insight in AN. Level of evidence Level III, Evidence obtained from well-designed cohort or case-control analytic studies.
