Using the Waldrop scale, minor physical anomalies were studied in 82 C
aucasian subjects, including 41 schizophrenic and 8 bipolar adults, as
well as 14 normal and 19 mentally retarded adults. An increased incid
ence of minor physical anomalies was found in the mentally retarded ad
ults relative to the other groups. Consistent with previous studies, t
here was a trend for the total mean Waldrop score of the schizophrenic
group to be higher than the mean score of the normal group. Minor phy
sical anomalies (assessed by the Waldrop scale), however, appear to be
of questionable utility in identifying ''congenital'' schizophrenia,
at least as this putative subgroup of schizophrenia is currently conce
ptualized.
