NOTE: Data were available from between 431 men and 618 women (social and simple phobia symptoms) and 502 men and 620 women (conduct disorder and all substance dependence symptoms) participants. All significance levels were adjusted for the dependence of the twin observations. For each symptom count variable, a t test for the difference between dependent correlations (Steiger, 1980) was used to evaluate whether correlations differed significantly for PPI-I versus PPI-II in either men or women.

Coefficients that differed significantly from one another (p < .005).
