PAINT-P microtrial

Status: completed

In PAINT- P, PhD student Rianne Hornsta, as part of her PhD research, investigated the effectiveness of different components of behavioural parent training for children with ADHD symptoms.

The effects of stimulus control (antecedent) and contingency management (consequent) techniques were investigated. The data collection of this study has been completed. In total, parents of 92 children from all over the Netherlands participated. The results have been written up and published in scientific articles and presented at (inter)national congresses.

We are proud to report that parents are enthusiastic about the training and that positive results are found from both trainings (antecedent and consequent interventions) on (daily measures of) improving problem behaviour in children with ADHD. Antecedent-based techniques appear to be especially important in addressing inattention.


A meta-analysis examines the components that moderate the effect of behavioural parent and teacher training. The meta-analysis has been completed and we are in the process of publishing the results. We investigated which components of behavioural parent and teacher training are associated with the effect on ADHD symptoms and behavioural problems of the child. We also conducted a meta-analysis to determine which components of parent training are associated with the effect on parent outcomes (parenting, parent-child relationship and parental mental health).

Single case studies

Through a series of single case experiments, the additional effect of contingency management on top of stimulus control techniques is investigated. Six parents of children with ADHD eventually participated in this study and the results are currently being written up in a scientific article.

Other projects


In the Paint-T trial, the effectiveness of the components of teacher training was examined by means of a microtrial, and in the follow-up study Paint T trial, the effectiveness of a combined teacher training will be examined.


In PAINT-IPDMA, an individual participant data meta-analysis is being conducted on psychosocial treatments for children and adolescents with ADHD. In the follow-up IPDMA study, the psychosocial treatments for children and adolescents with behavioural problems are investigated.


The aim of PAINT-S is to investigate the efficacy of an intervention to improve the interaction between children with ADHD and their siblings.


The PAINT-C study maps the care for children with ADHD and/or hyperactive behaviour in the Netherlands at municipalities, CJGs/District Teams and schools and investigates what predicts treatment choices in ADHD.


The study PLOS (Planning at School) investigates the effectiveness of a programme to support secondary school students with planning problems. PLOS consists of two parts PLOS-basic and PLOS-extra.


In PAINT-P the effectiveness of the components of parental training for ADHD was studied and in the follow-up studies Paint-POH, Paint-GZ and Paint-Pc the effectiveness of combined parental training in different settings will be studied.
