European Validation of the Self-Evaluation of Negative Symptoms (SNS): A Large Multinational and Multicenter Study
TLDR
In a large European multicentric sample, this study demonstrated that the SNS has good psychometric properties with good convergent and divergent validities; an association with patients' functional outcome; and the capacity to identify subjects with negative symptoms that is close to the BNSS and superior to the PANSS negative subscale.
Validation of the Arabic version of the “self-evaluation of negative symptoms” scale (SNS)
TLDR
This study is the first to validate the Arabic version of the SNS in patients with schizophrenia, and would help improve treatment by correctly assessing negative symptoms, thus optimizing treatment options.
Updated perspectives on the clinical significance of negative symptoms in patients with schizophrenia.
TLDR
The conceptualization, assessment, and treatment of this complex psychopathological dimension of schizophrenia is provided, and the development of state-of-the-art assessment instruments made in the last decades are provided.
EPA guidance on assessment of negative symptoms in schizophrenia
TLDR
This European Psychiatric Association (EPA) guidance recommends the use of persistent negative symptoms (PNS) construct in the context of clinical trials and highlights the need for further efforts to make the definition of PNS consistent across studies in order to exclude as much as possible secondary negative symptoms.
Negative symptoms in schizophrenia: correlation with clinical and genetic factors.
TLDR
It was showed that higher self-evaluation of negative symptoms scale scores were significantly associated with higher age, higher chlorpromazine-equivalent daily dose for typical antipsychotics and in married patients, and both clinical and genetic factors could help improve the treatment of patients.
Psychopathology and Integrity of the Superior Longitudinal Fasciculus in Deficit and Nondeficit Schizophrenia
TLDR
It is confirmed that DS patients have greater negative psychopathology than NDS patients, and frontoparietal dysconnection plays a role in its etiopathogenesis.
Validation of the French Clinical Assessment Interview for Negative Symptoms in a Sample of Stable French Individuals With Schizophrenia
TLDR
The results indicate that the French CAINS has robust psychometric properties and is a valid tool for evaluating negative symptoms in French-speaking individuals diagnosed with schizophrenia.

The brief negative symptom scale: validation of the German translation and convergent validity with self-rated anhedonia and observer-rated apathy
TLDR
Overall, the German BNSS shows good psychometric properties comparable to the original English version, and extends beyond interview-based assessments of negative symptoms to self-rated anhedonia and observer-rated apathy.
Validation of the Danish version of the brief negative symptom scale
TLDR
Overall, BNSS holds appropriate psychometric properties in terms of reliability and validity, however, discriminant validity was compromised by correlations with positive symptoms and Parkinsonism.
Validation of Turkish version of brief negative symptom scale
TLDR
This study confirms that the Turkish version of BNSS is an applicable tool for the evaluation of negative symptoms in schizophrenia.
The Clinical Assessment Interview for Negative Symptoms (CAINS): final development and validation.
TLDR
The CAINS is an empirically developed and evaluated measure of negative symptoms that is brief yet comprehensive and employable across a wide range of research and clinical contexts.
Polish version of the Brief Negative Symptom Scale (BNSS).
TLDR
The obtained results indicate good psychometric properties of the Polish version of the BNSS and its possible usefulness in the study of negative symptoms of schizophrenia conducted in Poland.
The positive and negative syndrome scale (PANSS) for schizophrenia.
TLDR
Review of five studies involving the PANSS provided evidence of its criterion-related validity with antecedent, genealogical, and concurrent measures, its predictive validity, its drug sensitivity, and its utility for both typological and dimensional assessment.
