%X A sample of 103 outpatients suffering from schizophrenia or schizoaffective disorders and presenting persistent psychotic symptoms over the previous three months was assessed using the PSYRATS. Seventy-five sample participants were also assessed with the Positive And Negative Syndrome Scale (PANSS).ICCs were superior to .90 for all items of the PSYRATS. Factor analysis replicated the factorial structure of the original version of the delusions scale. Similar to previous replications, the factor structure of the hallucinations scale was partially replicated. Convergent validity indicated that some specific PSYRATS items do not correlate with the PANSS delusions or hallucinations. The distress items of the PSYRATS are negatively correlated with the grandiosity scale of the PANSS.The results of this study are limited by the relatively small sample size as well as the selection of participants with persistent symptoms. The French version of the PSYRATS partially replicates previously published results. Differences in factor structure of the hallucinations scale might be explained by greater variability of its elements. The future development of the scale should take into account the presence of grandiosity in order to better capture details of the psychotic experience.Psychosis is a complex disorder that expresses itself in a variety of different ways. The clinical assessment of the experience of psychosis is a challenge for health care professionals to communicate precisely amongst one another. It is also difficult to accurately measure the efficacy of treatments. Different scales have been developed to measure the presence and severity of symptoms of the illness. These tools, such as the Positive and Negative Syndrome Scale (PANSS) [1], the Scale for the Assessment of Positive Symptoms (SAPS) [2] or the Brief Psychiatric Rating Scale (BPRS) [3], measure a broad range of experiences and behaviours, something which restricts the detailed measurement of specific symptoms
