Whereas depression is indeed one of the strongest predictors of suicidal thoughts across many different countries, it is disorders characterized by anxiety and poor impulse-control that best predict which people act on such thoughts—especially in developing countries, says a multi-country study published in this week's open access journal PLoS Medicine. more
