Influence of secondary sources in the Brief Negative Symptom Scale

Negative symptoms are core symptoms of schizophrenia associated with poorer clinical outcome (Strauss et al., 2010). They can be clinically subdivided into primary and secondary features, representing different phenomenology and pathophysiological mechanisms (Miller et al., 1994). Secondary negative symptoms phenotypically present as primary symptoms, but are attributed to external causes. Positive symptom severity, depression and antipsychotic side-effects are known sources of secondary negative symptoms (Carpenter et al., 1985).
