Objective: To develop a reliable standardized assessment of psychiatric symptoms for use in clinical practice. Method: A 50‐item interview, the Current Psychiatric State 50 (CPS‐50), was used to assess 237 patients with a range of psychiatric diagnoses. Ratings were made by interviewers after a 2‐day training. Comparisons of inter‐rater reliability on each item and on eight clinical subscales were made across four international centres and between psychiatrists and non‐psychiatrists. A principal components analysis was used to validate these clinical scales. Results: Acceptable inter‐rater reliability (intra‐class coefficient > 0.80) was found for 46 of the 50 items, and for all eight subscales. There was no difference between centres or between psychiatrists and non‐psychiatrists. The principal components analysis factors were similar to the clinical scales. Conclusion: The CPS‐50 is a reliable standardized assessment of current mental status that can be used in clinical practice by all mental health professionals after brief training.
