Reliability and validity of the Nepean Beliefs Scale for delusions and overvalued ideas in chronic schizophrenia: analysis of a preliminary pilot study.
Front Psychiatry
December 2023
Graduate School of Arts and Sciences, The University of Tokyo, Meguro, Japan.
Article Synopsis
- The Nepean Beliefs Scale (NBS) is a tool that assesses pathological beliefs in psychiatric disorders, specifically focused on delusions and overvalued ideas in chronic schizophrenia patients.
- In a study involving 28 individuals, multiple raters evaluated the beliefs of these patients using the NBS alongside other established assessments, demonstrating strong reliability and correlation with these scales.
- While the NBS showed sufficient reliability and validity for use in chronic schizophrenia, the authors emphasized the need for clear instructions and examples to ensure accurate responses from patients.

Article Synopsis
- Individuals with anorexia nervosa often deny their extreme weight loss and may underreport unhealthy eating habits, showing a lapse in insight about their condition.
- The study adapted the Nepean Belief Scale to Italian to assess the strength of these beliefs in patients with anorexia nervosa and their clinical implications.
- Results indicated the adapted scale is reliable and valid, revealing a connection between stronger beliefs and poorer cognitive function, while no significant links were found with age, BMI, or levels of depression.

Department of Psychiatry, Vrije Universiteit Amsterdam, Amsterdam UMC, Amsterdam, the Netherlands; Department of Anatomy & Neurosciences, Vrije Universiteit Amsterdam, Amsterdam UMC, Amsterdam, the Netherlands; Amsterdam Neuroscience, Compulsivity, Impulsivity & Attention, Amsterdam, the Netherlands.
Background: Poor insight in obsessive-compulsive disorder (OCD) is associated with higher symptom severity, more comorbidities, and worse response to treatment. This study aimed to elucidate underlying mechanisms of poor insight in OCD by exploring its neurobiological correlates.
Methods: Using a symptom provocation task during functional magnetic resonance imaging, we compared brain activation of patients with poor insight (n = 19; 14 female, 5 male), good/fair insight (n = 63; 31 female, 32 male), and healthy control participants (n = 42; 22 female, 20 male) using a Bayesian region-of-interest and a general linear model whole-brain approach.

Objective: COVID-19 conspiracy theories have become widespread since the onset of the pandemic and compound the existing challenges of decisional capacity assessment. This paper aims to review the literature pertaining to decisional capacity assessment in the context of COVID-19 conspiracy beliefs and synthesize a practical approach with an emphasis on differential diagnosis and clinical pearls for the practicing physician.
Methods: We reviewed papers on decisional capacity assessment and differential diagnosis in the context of COVID-19 conspiracy beliefs.
