Failure to find evidence of schizophrenia in first-degree relatives of schizophrenic probands
HG Pope Jr, JM Jonas, BM Cohen and JF Lipinski
The first-degree relatives (N = 199) of DSM-III schizophrenic probands (N =
39) were diagnosed from chart data by a rater who was blind to proband
diagnosis. No cases of even "possible" schizophrenia were found. This
augments the growing evidence that the genetic component in schizophrenia
may be less than was formerly suspected.
