A team of researchers and clinicians at the University
of Pisa, Italy, compared outcomes for 29 6- to 10-year-olds who received
an 11-week psychotherapy protocol and 29 comparison children who qualified
for the protocol but were referred to community services because slots
were unavaible for the psychotherapy protocol. Although the groups were
not randomly assigned, they did not differ significantly in baseline
characteristics. From the baseline assessment (Time 1) to the first
reassessment 6 months later (Time 2), 14 of the 29 comparison children
received treatment elsewhere. Between Time 2 and a 2-year follow-up
reassessment (Time 3), mental health services were sought for 34% of
the comparison children vs. 10% of the children who had received the
psychotherapy protocol. On the Children's Global Assessment Scale (C-GAS)
and the CBCL, both groups showed improvement from Time 1 to Time 2,
but only the C-GAS showed signficantly more improvement for the psychotherapy
group than the community services group. From Time 2 to Time 3, the
C-GAS showed no more improvement for the psychotherapy group than for
the community services group. However, the CBCL showed significantly
greater improvement for the psychotherapy group than for the community
services group on the Total Problems, Internalizing, Externalizing,
Withdrawn, Anxious/Depressed, Attention Problems, Delinquent Behavior,
and Aggressive Behavior scales. Furthermore, by Time 3, significantly
more of the psychotherapy group than the community services group had
moved to the normal range on several CBCL scales. The authors concluded
that the CBCL "data seem to provide evidence of a 'sleeper effect'"
whereby "changes in insight and self-awareness may produce more
of a delayed treatment effect than in behavioral treatments" (p.
337).
