Utviklingen i barns utagerende atferd og mødres oppdragelsespraksis etter foreldretrening

«The Incredible Years» is a parent training program that has been implemented across Norway. Although the program shows positive results, not all children benefit equally well from this program. Hierarchical linear modelling (HLM) was used to examine the effects of an ADHD diagnosis, early co morbid internalizing- and externalizing problems, and maternal stress following the development of conduct problems and harsh parenting. Mothers of 97 four-to-eight year old children with conduct problems participated in this study. Findings indicated that children with ADHD, co-morbid internalizing- and externalizing problems, and maternal elevated levels of stress were perceived as more aggressive at the pre-treatment phase. Neither of the predictors indicated a varying development from the pre-treatment phase until follow up one year after the study, in child conduct or in maternal harsh parenting when comparing these children to their counterparts. Viewed against these findings, «The Incredible Years» seems a treatment program suited to the treatment of conduct problems also in cases when additional risk factors are present.
