Given the recent treatment paradigm shift in psychosis, focusing on the recovery process, new assessment tools are needed. The Clinical Interview for Psychotic Disorders (CIPD) is an integrative and comprehensive assessment tool for psychotic disorders. CIPD encompasses the evaluation of diagnosis, psychosocial correlates and most relevant comorbidities. The study's aims were to examine CIPD inter-rater reliability, the relationships between CIPD and other instruments assessing positive and negative symptoms and functionality, and to explore participants’ qualitative feedback. The sample included 30 individuals with psychotic disorders, aged between 18 and 62 years old. Two experts in clinical psychology conducted the interviews and independently rated other assessment tools (PANSS, GAF and PSP) to determine severity of psychotic symptoms and levels of functionality. Results indicated high inter-rater reliability for the majority of CIPD items and agreement regarding diagnosis was between 73% and 93%. Moreover, positive and moderate to strong correlations were found between CIPD, PANSS, GAF and PSP. From the qualitative analysis five themes emerged, namely: CIPD applicability and utility, comparison with previous interviews, interviewer aspects, negative and positive aspects. Overall, these preliminary results suggest that CIPD is a reliable and valid assessment instrument that seems to be well suited for people with psychosis.
