Abstract
Objective:To validate an Urdu translation of premature ejaculation diagnostic tool (PEDT) by analyzing the association of this diagnostic tool with the clinical diagnosis of premature ejaculation (PE) and intravaginal ejaculatory latency time (IELT).Methods:This cross-sectional study was conducted at the urology section of the Aga Khan University Hospital, Karachi, for six months duration, from July 2018 to December 2018. In our study 108 subjects, aged 20 to 50 years, who were in a stable sexual relationship (heterosexual) for a minimum duration of six months, were asked to fill the Urdu version of PEDT, 61 with PE and 47 without PE.Results:The two groups matched for mean age, duration of relationship and education level. The duration of 1.2 (±0.5) minutes was the mean self-estimated IELT in the PE group and 3.7±0.9 minutes in patients without PE. There was a significant negative correlation of 0.6 (p-value <0.001) between the PEDT score and self-estimated IELT. The test-retest reliability for each item was found to be significant for each individual item (≥ 0.84, p-value <0.001) and 0.94 was the correlation coefficients of the total score, showing an excellent test-retest reliability. 0.93 was the Cronbach’s alpha score (95% Confidence interval = 0.905 - 0.948) indicating a significant internal consistency in the Urdu version of PEDT.Conclusions:The Urdu version of PEDT is a valid tool to define and quantify PE objectively, with adequate internal consistency. This version of PEDT has a good negative correlation with self-estimated IELT and excellent correlation with clinical PE.
Highlights
Premature ejaculation (PE) is an ejaculatory disorder with a highly variable estimated prevalence which is partly explained by the lack of standardized definitions and diagnostic tools.[1]
Mean selfestimated intravaginal ejaculatory latency time (IELT) was lower in the PE patients, (1.2 ± 0.52min) as compared to the non-PE patients (3.7 ± 0.91min). (Table-I)
Regarding the diagnostic value of Urdu version of premature ejaculation diagnostic tool (PEDT) score, we found a negative correlation of 0.6 between the PEDT and self-estimated IELT (p-value
Summary
Premature ejaculation (PE) is an ejaculatory disorder with a highly variable estimated prevalence which is partly explained by the lack of standardized definitions and diagnostic tools.[1]. Two of the most commonly used tools to diagnose PE, based upon patient-reported outcomes are Arabic Index of Premature Ejaculation (AIPE) and Premature Ejaculation Diagnostic Tool (PEDT). PEDT has standardized the diagnosis of PE and has already been translated and validated in various languages. An Urdu translation and validation of PEDT does not exist. Urdu is the language widely spoken and understood in Pakistan with a population of around 217 million (worldmeter.info).[5]. PE has a negative effect on quality of life, which extends beyond sexual dysfunction. Despite these serious psychological consequences of PE, only a few men seek treatment. We aimed to develop a validated translation of PEDT to be used in the Urdu speaking population. Urdu being a living language, spoken by almost a 100 million people around the world[6] (ORGI, 2011)
