Negative symptom dimensions differentially impact on functioning in individuals at-risk for psychosis

There is a growing interest in studying negative symptoms in individuals with at-risk mental state (ARMS) for psychosis. Negative symptoms are a core feature of schizophrenia and related psychoses. It is recognized that negative symptoms are prevalent in the prodromal phase of illness and predate the onset of attenuated positive symptoms (Yung and McGorry, 1996; Hafner et al., 2003; Lencz et al., 2004; Lyne et al., 2014). Previous research has suggested that more severe negative symptoms at baseline may predict transition from ARMS to full-blown psychosis (Demjaha et al., 2012; Piskulic et al., 2012; Nelson et al., 2013; Valmaggia et al., 2013).
