Many studies have identified a strong link between suicide and diagnosable mental illness,

especially depression. So, because women suffer from depression at a much higher rate than men, they would seem to be at higher risk for suicide. Yet, women actually commit suicide about one fourth as often as men.

George E. Murphy, professor of psychiatry at Washington university school of Medicine in St. Louis, says that females may be protected because of the way they think about problems and interact with others. "Women process their experience with friends. They discuss their feelings, seek feedback, and take advice. They are much more likely to tell a physician how they feel and cooper ate in the prescribed treatment. As a result, women get better treatment for their depression."

That treatment may help protect them from suicide, but Murphy suggests there is more to it. The approach to problem-solving is what often lands a woman in a psychiatrist's office in the first place, and that approach may be keeping female suicide rates lower.

Murphy believes women are less inclined to commit suicide because their thinking is more inclusive. While a man might tend to throw aside seemingly peripheral(非本质的，边缘的)issues to get to the core of a problem, a woman might take more things into account. She may continue to seek input and process problems long after the point where men decide on a course of action. "She'll consider not just her feelings, but also the feelings of others-her family, the children, even acquaintances-and how these people will be affected by a decision like suicide. A man is much less likely to take those things into account. He makes his decision, and it's about him, so he does not feel the need to share it with anyone else."
