Translation, adaptation, and clinical validation of the Premature Ejaculation Diagnostic Tool in Spanish (Colombia)

Background

Premature ejaculation is the most prevalent form of sexual dysfunction in men. The Premature Ejaculation Diagnostic Tool (PEDT) is an instrument used to evaluate premature ejaculation. It offers adequate psychometric properties and good reliability.

Aim

To adapt and validate a Colombian version of the PEDT in Colombian clinical and nonclinical samples.

Methods

Two samples were used in this study. The first was made up of 1110 men who were recruited to evaluate validity and reliability. Their ages ranged from 19 to 65 years (mean ± SD, 39.71 ± 12.53). The second sample included 123 men (66.7%) who did not meet diagnostic criteria for premature ejaculation per the International Statistical Classification of Diseases and Related Health Problems (ICD-10), while 33.3% met ICD-10 criteria for this dysfunction. Their ages ranged from 18 to 65 years (34.19 ± 12.65). Scores were used to calculate the cutoff.

Outcomes

A translated and adapted version of the PEDT was developed specifically for Colombia. All participants completed the Colombian version of the PEDT, a sociodemographic questionnaire, the Colombian version of the Massachusetts General Hospital-Sexual Functioning Questionnaire, and a semistructured interview based on the ICD-10.

Results

The results showed adequate psychometric properties and satisfactory internal consistency and confirmed the 1-dimensional factorization of the scale. According to ICD-10 criteria, the study also confirmed significant differences between participants who self-reported premature ejaculation and those who did not. In addition, it showed adequate evidence of convergent validity, with a moderate correlation with sexual functioning scores. As a result, the cutoff point was set to 10.5, with an area under the curve of 96.8%. Therefore, a score ≥11 points suggested the presence of premature ejaculation.

Clinical Translation

The current Colombian version of the PEDT is a useful instrument that determines the presence of premature ejaculation that is compatible with ICD-10 criteria.

Strengths and Limitations

The Colombian version of the PEDT presents evidence of reliability and validity, a confirmed 1-dimensional factorization, and a cutoff point for Hispanic populations. More in-depth evaluation of the diagnosis of premature ejaculation is required, and further research among other Spanish-speaking countries and sexual minorities is recommended.

Conclusion

The Colombian version of the PEDT is a psychometric adequacy tool for evaluating and diagnosing premature ejaculation, following the ICD-10 criteria.

Colombian Clinical Validation of the International Index of Erectile Function (IIEF-5)

Background

Erectile dysfunction represents an important health problem and the instrument most frequently used for the evaluation of its evaluation is the International Index of Erectile Function (IIEF-5).

Aim

Due to lack of adaptation and validation for Spanish-speaking populations, this study aimed to adapt and validate the Colombian version of International Index of Erectile Function (IIEF-5).

Methods

Two independent samples were evaluated. One used to validate the scale and the other to calculate cut-off point of this version, with 2,021 men from the general population and outpatients from a clinic. The age range was 18 to 75 years old (M = 37.80; SD = 14.06). The second sample included 74 men, 64.9% did not meet DSM-5 criteria for erectile dysfunction, and 35.1% meet DSM-5 criteria to ED. Age range was 19 to 73 years old (M = 40.38; SD = 13.22).

Outcomes

All participants answered the Spanish versions of the International Index of Erectile Function-5 (IIEF-5) and the Massachusetts General Health-Sexual Functioning Questionnaire.

Results

The Colombian version of IIEF-5 showed adequate psychometric properties, confirmed the one-dimension factorization of the scale, and showed adequate evidence of reliability and validity. Significant differences were observed in the IIEF-5 total score between the non-clinical and clinical groups who meet DSM-5 criteria for erectile dysfunction, with a large effect size. Also, the cut-off the Colombian version was set to 16, with an area under the curve of 94.9%.

Clinical Implications

The Colombian version of the IIEF-5 is a useful evaluation instrument that provides to determine the presence of erectile dysfunction compatible with DSM-5 criteria.

Strengths & Limitations

The inventory reports adequate psychometric properties, a confirmed one-dimensional structure, evidence of reliability and validity, and the first cut-off point for Hispanic populations. A more in-depth evaluation of the diagnosis of ED and thus replication in other Spanish-speaking countries and sexual minorities is recommended.

Conclusion

The Spanish version of the IIEF-5 is a useful evaluation tool for identifying erectile dysfunction, following DSM-5 criteria.
