De modererende rol van programma integriteit en IQ in het effect van het EQUIP programma op cognitieve vertekeningen. Een quasi-experimenteel onderzoek op twee Praktijk scholen in Utrecht

Abstract

In a quasi-experimental pre/posttest-treatment design the effect of the cognitive behavioral program EQUIP on cognitive distortions was investigated among high school youth with a mental retardation. Furthermore, it was investigated whether program integrity and IQ moderate the effect of EQUIP on cognitive distortions and which main category of program integrity explains the effect the best. The sample consisted of an experimental group (n = 81) that participated in EQUIP and a control group (n = 35) that did not receive EQUIP. In the first grade, EQUIP was found to have an effect on the reduction of cognitive distortions (minimizing/mislabeling and assuming the worst). In the second grade, EQUIP showed a reversed effect on the cognitive distortion minimizing/mislabeling. Program integrity moderated the effect of EQUIP on cognitive distortions (blaming others, minimizing/mislabeling and assuming the worst) in the first grade. None of the main categories of program integrity explained the effect of EQUIP on cognitive distortions. Finally, IQ did not moderate the effect of EQUIP on cognitive distortions. The positive effect in the first grade may be attributed to the variant that has been offered: ‘EQUIP for Educators’. Follow-up study must concentrate on the difference between the EQUIP variants in the Netherlands and the effect of EQUIP among youth with a low IQ.
