ABSTRACT Background

Studies have demonstrated that erectile dysfunction has a well-established bidirectional relationship with depression and have indicated an independent association of type D personality (TDP) with depression. Nevertheless, the relationship of erectile dysfunction with TDP has not been sufficiently examined.

 Aim

To examine the associations among depression symptoms, TDP, and erectile dysfunction.

 Methods

The cross-sectional study recruited 1740 sexually active Taiwanese men (age: 20–40 years) with erectile dysfunction. Participants completed an online questionnaire collecting general demographic information and containing the International Index of Erectile Function-5, Type D Scale-14, and Depression and Somatic Symptom Scale. Pearson’s chi squared or Student’s t’test was conducted for comparisons between participants with vs without TDP. We conducted multivariate and univariate logistic regression analysis to investigate the predictors of moderate/severe erectile dysfunction.

 Outcomes

The prevalence of TDP and moderate/severe erectile dysfunction, the associations between TDP and the severities of depression symptoms and erectile dysfunction, and independent risk factors for moderate/severe erectile dysfunction.

 Results

A total of 360 (15.9%) and 941 (54.08%) men had moderate/severe erectile dysfunction and TDP, respectively. Men with TDP reported significantly higher total and subscale scores in the International Index of Erectile Function-5 and the Depression and Somatic Symptom Scale; this group also exhibited higher prevalence of moderate or severe erectile dysfunction. According to the univariate analysis, all variables significantly predicted moderate or severe erectile dysfunction except for age and body mass index. A multivariate analysis revealed TDP status and depression symptoms to be independent predictors of moderate or severe erectile dysfunction. With regard to subscales of the Type D Scale-14, we discovered that social inhibition had a greater influence on moderate or severe erectile dysfunction than had negative affectivity. A mediation analysis indicated that the relationship between TDP and erectile dysfunction was mediated by depressive symptoms.

 Clinical Implications

Research has suggested that compared with the general population, individuals with TDP are less willing to seek medical consultation, have lower medication adherence, and have heightened risk of depression; urologists should strive to identify patients with TDP.

 Strengths & Limitations

This study is the first to investigate the association of TDP with erectile dysfunction in a large population of young men by using validated instruments. Conclusions on causality cannot be drawn due to the study’s cross-sectional nature.

 Conclusion

This research revealed relationships among TDP, depression symptoms, and erectile dysfunction in Taiwanese young men.
