[Training of aggressive children in residential treatment ages of five to seven years]. / Training mit aggressiven Heimkindern im Alter von fünf bis sieben Jahren.

The paper reports about strategies in behavior modification with aggressive children (sensu Petermann and Petermann, 1991) in special education ("Heimerziehung"). New results of treatment with nursery students are discussed. The modified conception (single and group sessions with child/children) are illustrated. Single-Case hypotheses were tested with the help of reversal designs (based on 105 observations). The differences of means between the phases of the observation (incl. the t-tests) are evaluated. The single-case analyses showed positive effects. Only the support by parents guarantees positive long-term effects.
