Double suicides usually involve older married couples. Histories of four such couples are reviewed. The participants were similar to other suicides with regard to recent visits to physicians, alcohol use, & communication of intent. They differ from other suicides in that they are more likely to have a first-degree relative who died by suicide. Similar DSM-III diagnoses were found in both members of each couple, & there was a complementary qualtiy in their personal & family histories. 8 REF.
