assumption for the weighted least square estimator was not violated. Table 5 summarizes means and covariance matrices of the ASB and ALC factors from different ages estimated from a CFA with unstructured means and covariance matrix. Means of ASB factors increased from age 12 to age 15 and declined between ages 15 and 17. Males had higher levels of antisocial behavior than females at all ages. Means of ALC factors increased between ages 12 and 17 in both females and males without noticeable sex differences. The variances of both ASB and ALC factors decreased throughout the included age range.
