Cognitive Behavior Therapy for Schizophrenia: Effect Sizes, Clinical Models, and Methodological Rigor
CBTp had beneficial effect on positive symptoms, however, psychological treatment trials that make no attempt to mask the group allocation are likely to have inflated effect sizes.
The structure of paranoia in the general population
The paranoia continuum has implications for the aetiology, mechanisms and treatment of psychotic disorders, while confirming the lack of a clear distinction from normal experiences and processes.

The multidimensional measurement of the positive symptoms of psychosis
It is advised that the PSYRATS should not be used as a total score alone, whilst further research is needed to clarify the best use of potential subscales.
Schizotypy: A Vulnerability Factor for Traumatic Intrusions
