“…When samples are expanded to include the full spectrum of psychoses, broadly similar fi ve-factors solutions are found, (Dikeos et al, 2006;Kitamura et al, 1995;Lindenmayer et al, 2004;McGorry et al, 1998;McIntosh et al, 2001;Murray et al, 2005;Ratakonda et al, 1998;Serretti et al, 2001;Serretti and Olgiati, 2004), though there may be confl ation of the disorganized and negative dimensions especially in fi rst onset samples (McGorry et al, 1998). It seems that the dimensions generated from established cases of psychosis provide reasonably replicable, stable solutions in a variety of settings, diagnostic groups and patient samples; however the factor structure may be less stable around the time of presentation (Drake et al, 2003).…”

In this paper, we discuss the conceptual background for including a dimensional component to the DSM V diagnoses for psychoses. We review the evidence for a continuous distribution of psychosis like symptoms in the general population and summarise the research validating the clinical usefulness of psychopathological dimensions. We conclude that diagnostic models using both categorical and dimensional representations of psychosis have better predictive validity than either model independently. Dimensions do not appear to be diagnosis specific so a flexible scoring of dimensions across all psychotic and major affective disorders may be potentially more informative than a system where categorical diagnoses are kept artificially dimension-specific.

“…A specific scale for depression in schizophrenia was not available in the original trial. The PANSS items used for the paranoia factor were also internally consistent (Drake et al 2003). The insight factor used was chosen to combine objective and subjective assessments from the PANSS and BIS respectively.…”

time to remission and suicidality. Results: Two groups of patients were identified; H (n = 16) and D (n = 106). 179 patients experienced both hallucinations and delusions (dual symptom group). The H group was significantly younger, had a longer duration of untreated psychosis, poorer premorbid function and better insight than the D group. Notably, the H group scored higher on measures of suicidality, and at 5 years follow-up a significantly higher proportion of patients was lost to suicide in this group. The dual symptom group was closer to the D group on significant parameters, including suicidality and suicide rate. Conclusions: Patients with hallucinations only can be separated from patients with delusions only and the subgroups differ with regard to demographical data, clinical variables and notably with regard to suicidality. These findings suggest distinctions in the underlying biological and psychological processes involved in hallucinations and in delusions. Key WordsHallucinations ؒ Delusions ؒ Psychotic symptoms ؒ Suicide Abstract Background: The main aim of this study was to identify subgroups of patients characterized by having hallucinations only or delusions only and to examine whether these groups differed with regard to demographic characteristics, clinical characteristics and outcome factors, including suicidality. Methods: Out of 301 consecutively admitted patients with first-episode psychosis, individuals with delusions only (D) and hallucinations only (H) were identified based on Positive and Negative Syndrome Scale (PANSS) items P1 (delusions) and P3 (hallucinations) scores at baseline and through 4 follow-up interviews over 5 years. The subgroups were compared with regard to demographic data, premorbid functioning, duration of untreated psychosis, clinical variables,
