Further evidence of the reliability and validity of the premature ejaculation diagnostic tool

Abstract

This study details the further validation of the Premature Ejaculation Diagnostic Tool (PEDT), a five-item tool, developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, revised version 4 (DSM-IV-TR), criteria in diagnosing presence or absence of premature ejaculation (PE). A total of 102 men completed the PEDT and were then interviewed by one of the seven clinical experts, who made a diagnosis of presence or absence of PE. The diagnoses from these two methods were compared to assess the convergent validity of PEDT. Retest reliability was also assessed, by men completing the PEDT a second time, approximately 2 weeks after the first administration. The level of agreement between clinical expert and PEDT diagnoses was very high (κ-statistic=0.80 (95% CI=0.68–0.92)), and retest reliability was very good – Intraclass correlation coefficient=0.88. In summary, the PEDT is extensively validated, self-report measure that can systematically assess DSM-IV-TR criteria to provide accurate diagnoses of PE/no-PE.
