Abstract
Negative symptoms reflect a currently much-untreated loss of normal functioning and are frequently found in psychotic disorders. We present the first translation of the Brief Negative Symptom Scale (BNSS) to European Portuguese and evaluate its validity in a sample of Portuguese male patients with a psychotic spectrum disorder. The Portuguese BNSS showed excellent internal consistency, high convergent validity (i.e., strong correlation with the PANSS negative factor), and high discriminant validity (i.e., a lack of association with the PANSS positive factor). In sum, the present European Portuguese BNSS has shown to be reliable, thus extending this instrument's clinical availability worldwide.
期刊介绍：
''Psychopathology'' is a record of research centered on findings, concepts, and diagnostic categories of phenomenological, experimental and clinical psychopathology. Studies published are designed to improve and deepen the knowledge and understanding of the pathogenesis and nature of psychopathological symptoms and psychological dysfunctions. Furthermore, the validity of concepts applied in the neurosciences of mental functions are evaluated in order to closely bring together the mind and the brain. Major topics of the journal are trajectories between biological processes and psychological dysfunction that can help us better understand a subject’s inner experiences and interpersonal behavior. Descriptive psychopathology, experimental psychopathology and neuropsychology, developmental psychopathology, transcultural psychiatry as well as philosophy-based phenomenology contribute to this field.
