The Florence Psychiatric Interview (FPI) is an interviewing instrument for evaluating psychopathology in the community. The FPI is designed to be completed by clinical interviewers, and focuses on single episodes of illness where the symptoms are assessed and graded according to their severity on five‐point scales. Psychiatric symptoms are evaluated regardless of their diagnostic collocation, and period and lifetime diagnoses may be generated by combining the episodes and using the appropriate algorithms (the information provided by the FPI covers the requirements of all the present diagnostic systems). Other aspects of psychiatric disorders that are usually ignored in other interviews are investigated (for example, costs of illness, use of health facilities, life events, and personality traits). Data on reliability (inter‐rater agreement and test‐retest reliability) and agreement with other instruments such as the Composite International Diagnostic Interview (CIDI) and the Structured Clinical Interview for the Diagnostic and Statistic Manual of Mental Disorders (SCID) seem encouraging. The FPI's ability to collect lifetime symptoms by combining episodes matches that of an interview (the CIDI) that uses the lifetime approach. Agreement between fully qualified psychiatrists and trained residents was excellent. The ability of the cases to recall symptoms experienced several years before was also acceptable. This instrument is therefore proposed for clinical studies at the epidemiological level. Copyright © 2001 Whurr Publishers Ltd.
