Trait-affect, depressed mood, and male sexual functioning: a preliminary study

Abstract

Introduction: The relationship between trait-affect, depressed mood, and sexual functioning has been studied; however, the nature of that relation is not yet well established.

Aim: The aim of the present study was to investigate the mediator role that depressed mood plays in the relation between trait-affect and sexual functioning in men.

Methods: A total of 205 men from the general population participated in the study and completed self-reported measures assessing trait-affect, depressed mood, and sexual functioning.

Main outcome measures: Trait-affect was measured by the Positive Affect-Negative Affect Scale-Expanded Version, depressed mood was assessed by the Beck Depression Inventory, and male sexual function was measured by the International Index of Erectile Function.

Results: Regression analysis showed that negative trait-affect and depressed mood were significant predictors of sexual functioning. Moreover, mediation analyses indicated that depressed mood partially mediate the relationship between negative trait-affect and sexual functioning in men.

Conclusion: Findings support the role of negative trait-affect and depressed mood on male sexual functioning.
