Neuroticism and extraversion in Turner's Syndrome.

Administered the Maudsley Personality Inventory to 5 groups of female Ss: (a) 13 Turner Syndrome Ss (mean age 19 yrs 2 mo) with karyotype 45X, (b) 18 Turner Syndrome (TS) Ss (mean age 26 yrs 11 mo) with other types of sex chromosomal abnormalities, (c) 16 sisters of Ss (mean age 24 yrs 2 mo), (d) 9 Ss with growth retardation and primary amenorrhea (mean age 22 yrs 4 mo), and (e) 19 nurses (mean age 22 yrs 8 mo). The results are compared to English and American normative values. The total group of TS Ss obtained a low Neuroticism (N) score compared to the control groups. When the total group was divided on the basis of their karyotypes, the low N score could be referred solely to Ss with karyotype 45X, who scored significantly lower than any other group tested so far with the MPI. TS Ss with chromosomal abnormalities other than 45X scored within normal limits. No variables other than karyotype 45X were related to an extremely low N score. It is concluded that exceptional emotional stability, as reflected in a very low N score on the MPI, is concomitant with the total absence of one sex chromosome, which is probably due to a developmental abnormality of the CNS.
