Validation of the Danish version of the brief negative symptom scale.

Conclusions: Overall, BNSS holds appropriate psychometric properties in terms of reliability and validity. However, discriminant validity was compromised by correlations with positive symptoms and Parkinsonism. The former originates presumably from NS secondary to positive symptoms since the sample included acutely psychotic patients, and the latter from overlapping rating criteria regarding facial expressivity impairment.
