The Journal of Sexual Medicine, 05/23/2012

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


  • 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.
  • 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.


  • 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.
