N2 - Depression occurring alongside psychosis is an important treatment target, both in its own right and as a potential maintenance factor for positive psychotic symptoms. The present paper reports a prospective longitudinal analysis of depression and its predictors over six months in a group of 60 participants experiencing persecutory delusions. We hypothesised that negative schematic beliefs about the self and problem solving difficulties would predict the persistence of depression over time. The results showed, as hypothesised, that more negative schematic beliefs about the self and poorer problem solving predicted higher depression scores six months later, beyond what could be predicted by baseline depression scores. These findings support a proposed role for schematic beliefs and problem solving difficulties in the perpetuation of depression occurring alongside psychosis, as has been substantiated for major depressive disorder. Interventionist research is warranted to confirm causal effects.
