Abstract

People diagnosed with a psychotic disorder show a selective attention to threat bias. However, it is unknown whether this attentional bias is specifically related to delusions or more generally to psychosis since the absence of the bias has not been established in people with psychosis (without delusions). It is also unknown when this bias develops in the course of psychotic disorder. These issues are investigated in people with first episode psychosis (FEP). The Stroop task was administered to three participant groups: a FEP group with current delusions (n = 31), a FEP group without current delusions (n = 11), and a non-psychiatric control group (n = 25). The FEP with delusions group showed a selective attention to threat words compared to the other groups (p = .02). Selective attention to threat is specifically related to delusions, is present early in the course of psychosis and may be candidate for new cognitive-behavioural therapies to treat medication-resistant delusions.
