The SAD-MEN questionnaire: a new and reliable questionnaire for assessing sexual dysfunction in Asians with diabetes

Validity and reliability of the Indonesian version of the International Index of Erectile Function

Objective:

This study aimed to evaluate the validity and reliability of the Indonesian-translated version of the International Index of Erectile Function (IIEF-15).

Subjects and methods:

A total of 100 male participants were involved in this study. Written consent was given by each participant before filling in the questionnaire. The original main structure and domains were kept in the translated version. Pearson product–moment correlation was used to test the validity of the results. The reliability was determined based on the Cronbach’s alpha internal consistency measurement and intraclass correlation coefficient.

Results:

The Pearson correlation findings indicate an excellent level of validity compared to the critical value table ( r>0.254, p<0.01). Almost every domain shows excellent internal consistency (α>0.9) and good reliability (0.75<α<0.90) except for sexual desire (α=0.631, r=0.461) and overall satisfaction (α=0.705, r=0.545), which show lower but acceptable consistency as well as moderate reliability, respectively. Overall, the questionnaire exhibits promising consistency (α=0.974) and reliability ( r=0.712).

Conclusion:

The Indonesian version of the IIEF-15 is valid and reliable to be used as both a clinical diagnostic tool and an instrument for further studies focusing on male sexual dysfunction in Indonesia.

The SAD-MEN questionnaire: a new and reliable questionnaire for assessing sexual dysfunction in Asians with diabetes

AIM

The aim of this study is to construct a new tool for the assessment of sexual dysfunction among men with diabetes that is valid and reliable across different ethnicities, languages and socio-economic backgrounds in South East Asia.

METHODS

Focus group interviews were conducted to determine the construct of the questionnaire. Content and face validity were assessed by a panel of experts. A pilot study was conducted to validate the Sexual Dysfunction in Asian Men with Diabetes (SAD-MEN) questionnaire in English and Malay. The International Index of Erectile Function-5 (IIEF-5) was used for comparison. Construct validity was assessed using exploratory factor analysis, reliability was determined using Cronbach's α (> 0.700), and test-retest reliability using Spearman's rank correlation coefficient.

RESULTS

The SAD-MEN questionnaire yielded moderate face and content validity, with high reliability as shown by Cronbach's α values of 0.949 for sexual performance and 0.775 for sexual desire for the English version. The Malay language questionnaire had a Cronbach's α value of 0.945 for sexual performance and 0.750 for sexual desire. Test-retest reliability using Spearman's test gave correlation coefficients of r = 0.853, P = 0.000 for the English language questionnaire and r = 0.908, P = 0.000 for the Malay language questionnaire.

CONCLUSION

The SAD-MEN questionnaire is a valid and reliable tool by which to assess sexual dysfunction in English- and Malay-speaking Malaysian and South East Asian men with diabetes.
