“…Therefore, younger men might be more stable in terms of their ejaculatory function and control compared to older men. This is somewhat supported by a study where test-retest reliability of the PEDT (ICC = 0.88) was higher in younger patients compared with older patients [32].…”

The aim of the present study was to investigate the psychometric properties of a translated and culturally adapted Iranian version of the Female Genital Self-Image Scale (FGSIS-I) in a sample of college women. Further, the relationship between women's self-image, body appreciation, sexual functioning, and gynecological exam behavior was explored. A sample of 1,877 female students from five different universities across Qazvin and Tehran completed the Female Sexual Function Index (FSFI), the Body Appreciation Scale (BAS), the Rosenberg Self-Esteem Scale (RSES), the FGSIS-I, and a gynecological exam behavior questionnaire. Good to excellent internal consistency reliability, test-retest reliability, and convergent and construct validity were found. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) both provided a two-factor structure for the FGSIS-I. The validity of the FGSIS-I in predicting gynecological exam behavior of college women was tested using structural equation modeling (SEM). The final model accounted for 33% of the variance in gynecological exam behavior (p < 0.01). In conclusion, the FGSIS-I was found to be a highly valid and reliable instrument to assess female genital self-image in Iranian women. ORIGINAL RESEARCH-EJACULATORY DISORDERS A B S T R A C TIntroduction. Premature ejaculation (PE) is one of the most prevalent male sexual problems. The Premature Ejaculation Diagnostic Tool (PEDT) is a suitable patient-reported outcome measure for the assessment of PE. Aim. To examine the psychometric proporties of a translated and culturally adapted version of the PEDT in a sample of Iranian men suffering from PE. Methods. Two independent samples were compared, one including patients with PE based on the DSM-IV-TR criteria (n = 269) and the other including healthy men without PE (n = 289). A backward-forward translation procedure was used to translate the PEDT into Persian. Both samples were asked to fill in the PEDT twice-at baseline and 4 weeks later. Main Outcome Measures. Internal consistency, test-retest reliability, convergent validity, factor structure, measurement invariance across sexual health status (i.e., between men with and without PE). Results. Mean ages of men without and with PE were 34.9 and 35.3 years, respectively. Cronbach's alpha coefficient for the total PEDT score was 0.89. All items and the total score were remarkably consistent between the two measurement points. All five PEDT items correlated at r = 0.40 or greater with their own scale, indicating good convergent validity. There was a high and significant correlation (r = −0.82, P < 0.001) between the PEDT score and IELT. Healthy men reported lower scores (fewer complaints) on the PEDT compared with the PE group. A singlefactor model was found to be best-fitting in the exploratory factor analysis; this was confirmed by confirmatory factor analysis. The PEDT was invariant across sexual health status and perceived similarly by men with and without PE.

“…The validity of the PEDT in diagnosing PE compared with clinical expert opion has been shown by the same group in another study. 12 In this study we carried out the Turkish validation of the PEDT. The use of factor analysis confirmed that the five-item solution used by Symonds et al is appropriate for use by Turkish men.…”

There are uncertain issues on the diagnostic methods of premature ejaculation (PE). The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria in diagnosing PE and the aim of this study is to carry out the Turkish validation of the PEDT and to evaluate its association with intravaginal ejaculatory latency time (IELT). A total of 94 patients with a self-reported complaint of PE and 88 men without PE were enrolled into the study and requested to complete the nine-item PEDT, which was translated into Turkish. The patients were also requested to measure IELT. All participants were requested to come for a second visit to assess the PEDT's retest reliability; data from 78 men in the PE group and 69 men in the control group were collected. The IELT data of 35 patients were also recorded. The mean age of the PE group and the control group were 39.4±9.7 (24-65) and 30.1±5.7 (20-56), respectively, (P ¼ 0.068). Among the patients in the PE group, 24 (68.5%) reported life-long PE, whereas 11 (31.5%) reported acquired PE. The geometric mean IELT of the PE group was 59.7 ± 46.2 (6.5-197.7) s. The number of men reporting IELTs of o1, 1-o2 and 42 min were 20 (57.1%), 11 (31.5) and 4 (11.4%), respectively. The factor analysis assessment showed that the five-item combination (questions 1, 2, 3, 4 and 8) explained 74.4% of the variance, there were no other combinations that explained the variance more effectively. Cronbach's alpha score of five-item combination was calculated as 0.77, showing adequate internal consistency. The overall Cronbach's alpha score did not increase if any item combination was deleted. The test-retest correlation coefficients of each item were higher than 0.80 and the correlation coefficient of the total score was 0.90. The PEDT and IELT showed an adequate correlation (q ¼ 0.44). As a conclusion, the validated five-item Turkish version of PEDT is a reliable questionnaire to screen PE among Turkish patients. Its significant association with IELT supports the fact that PEDT may be of benefit for the diagnosis of PE and measuring the response to treatment. In addition, PEDT seems to be more applicable than measuring IELT in our population, for the assessment of PE.

“…In the United States, the women were partners of men taking part in another study to develop a PE diagnostic tool. 22,23 Men taking part in the validation of the PE diagnostic tool either met the DSM-IV-TR classification for PE and had an intravaginal ejaculatory latency time (IELT) of less than 2 min at least 70% of the time, as measured over 4 weeks using a stopwatch, or they were diagnosed as having PE through a diagnostic interview conducted by a clinical expert. 12 These experts had several years of experience in active diagnosing practice and treating men with PE, and were recognized as thought leaders, published authors or clinical study investigators.…”

Sexual dysfunction in partners of men with premature ejaculation

Research in partners of men with erectile dysfunction suggests that a woman's sexual difficulties can be contingent on her partner's sexual dysfunction. However, little research has been conducted in partners of men with other sexual dysfunctions, such as premature ejaculation (PE). We evaluated 139 partners of men diagnosed with having PE and 89 age-matched women whose partners did not have any sexual dysfunction. Results showed that 77.7% of PE partners had at least one sexual dysfunction, compared to 42.7% of the control group. Further research needs to be undertaken to investigate the temporal relationship between sexual dysfunctions in both partners.
