The major findings were: (a) PSST, PMT, and PSST + PMT
were associated with significant improvements in overall child
dysfunction, prosocial competence, and aggressive, antisocial,
and delinquent behavior; (b) improvements were evident in performance
at home, at school, and in the community immediately
after treatment and at 1-year follow-up; (c) PSST + PMTgenerally had a more marked impact on measures of child aggression,
antisocial behavior, and delinquency, and parental
stress, depression, and other symptoms of parent dysfunction,
relative to PSST and PMT; and (d) PSST + PMT also placed a
greater proportion of youth within normative levels of functioning.
