摘要

Male erectile disorder (ED) impacts the sexual functioning of ten to twenty million men in the United States. Erectile disorder, as withother sexual dysfunctions, may be caused by, or associated with a number of diseases that impact the cardiovascular and nervous systems. However, men who have few physical problems may also experience the disorder due to psychological factors. Men who suffer from ED due to psychogenic factors are believed to differ from functional men in five key cognitive and behavioral domains. Barlow and Sbrocco (1996) used these differences to formulate a model of male sexual dysfunction that explicitly addresses the cognitive mechanisms involved in ED. The model proposes that a key point in the development of ED is whether or not a man feels challenged or threatened when experiencing a discrepancy between expected and actual performance. Men who are challenged by the experience typically have the skills necessary to identify and alleviate the discrepancy in performance. They are believed to use positive outcome expectancy and confidence to overcome suboptimal sexual performance and maintain function. In contrast, men who are threatened by discrepancies between expected and actual performance may expect a negative outcome and have little faith in their ability to sexually perform.
