Patients admitted to the Phoenix Program for sex offender treatment at Alberta Hospital Edmonton were separated by family history into a group of North American Indians and a group of Caucasians, with respective sample sizes of 53 and 192 after range matching the Caucasian to the North American Indian sample on a number of demographic variables. Controlling for body mass index and age, the two groups were equivalent in terms of 12 basic blood chemistry variables and 5 of 6 endocrine measures. Serum testosterone did differ significantly (p < .0005, covariate adjusted means of 22.3 and 26.5 nmol/L, respectively, for Caucasians and North American Indians). Further research will be required to establish the generality of this result and to ascertain the etiology. © 1997 John Wiley & Sons, Inc. J Clin Psychol 53: 375–385, 1997.
