data from young Dutch twins were used to obtain DSM-oriented scales assessing
affective and anxious problems, pervasive developmental problems and
oppositional and overactive behavior (Achenbach & Rescorla: Manual for
the ASEBA Preschool Forms & Profiles. Burlington, VT: Univ Vermont,
Dept Psychiatry, 2000). The large sample of 3-year-old twins (N = 6522 pairs)
was subdivided into 3 groups, based on Socio-economic status (SES) of the
parents (high, middle, low). Mean scores for all DSM-oriented scales are lower
in the highest SES group and higher in the lowest SES group. For the twin
correlations there is no clear pattern in the results as a function of
parental SES.
