We examined the risk of psychiatric illness in the first-degree relatives of the 257 depressed inpatients upon whom we constructed the Iowa Discriminant Index (IDI) for endogenous depression. Nonendogenous depressives had a higher rate of alcoholism and antisocial personality in their families. IDI endogenous subtyping was not associated with a family history of depression. These results provide additional support for the validity of the empirically derived IDI.
我们研究了257名抑郁症住院患者的一级亲属患精神疾病的风险，我们基于这些患者构建了用于内源性抑郁症的爱荷华判别指数（IDI）。非内源性抑郁症患者的家族中酗酒和反社会人格的发生率更高。IDI内源性亚型与抑郁症家族史无关。这些结果为经验性得出的IDI的有效性提供了额外支持。
