Research studies on suicidal behavior among twins are reviewed. It is found that no methodologically sound study on twins reared apart has yet appeared, & so firm conclusions cannot be drawn from the research. Monozygotic twins reared together were found to have higher concordance rates for suicide than dizygotic twins reared together. Confounding factors are discussed & suggestions made for future research. (28 refs)
