What is PAINT?

PAINT (Psychosocial ADHD Interventions) is the umbrella name for the studies carried out within the Consortium “ADHD en druk gedrag”. In this consortium, subsidized by ZonMw, a large number of Dutch practice institutes, research institutes and knowledge networks work together, with the aim of improving the care for children with ADHD and disruptive behavior. The various research projects involve teachers and health care professionals, parents, mental health care professionals, and employees of municipalities, district teams and centers for youth and family. Many members of the consortium are also active in the Academic Workshop on ADHD and Busy Behavior, an important platform for the dissemination of knowledge.

What are we researching in the PAINT studies?

In several subprojects we are conducting research on the following themes and questions:

1) The current practice of care and education for children with ADHD and disruptive behavior: what does the care in the Netherlands currently look like? Are proven effective interventions being used? Are guidelines being followed? And what factors influence the choices made in care?

2) Elements of proven effective interventions: what components of effective training for teachers and parents are effective? And might certain components or practices be more effective than others?

3) Customized care: for whom does which intervention work best? Are there subgroups of children or parents for whom certain interventions work better or less well?

4) Cost-effectiveness: what is the balance between the effectiveness and the costs of interventions?
