The androgen receptor gene and psychological traits: are results consistent in Sweden and Australia?
Studies in Sweden and Australia have examined the relationship between number of CAG repeats in the androgen receptor gene and psychological traits - three Masculinity-Femininity (M-F) measures in Australia, and the Karolinska Scales of Personality (KSP) in Sweden. The present study derived M-F scales from the KSP items, and scales corresponding to several KSP scales from the items of the inventories used in Australia, to permit cross-validation of the Australian results in the Swedish sample, and vice versa. The derivation of scales was facilitated by the fact that items from both inventories had been used with a large twin sample in the US. Correlation of the derived scales with androgen receptor gene CAG-repeat scores for women in the Australian and Swedish samples failed to provide clear evidence of replication of either set of original correlations in the other sample, although there were a few hints of consistency. It was concluded that if the number of CAG repeats on this gene is related to psychological traits at all, the relationship is a weak one.
