Insights
Parent training significantly improves ADHD symptoms in preschoolers, as rated by parents, with lasting effects. This evidence-based intervention shows value in routine care but did not impact conduct problems.
Area of Science:
- Child and Adolescent Psychiatry
- Behavioral Psychology
- Clinical Psychology
Background:
- Attention-deficit/hyperactivity disorder (ADHD) is common in preschool children, necessitating effective interventions.
- Parent training is a recommended intervention for preschool ADHD, but its efficacy compared to usual care requires robust evidence.
Purpose of the Study:
- To evaluate the effectiveness of an evidence-based parent training program (New Forest Parenting Programme) for preschool children with ADHD.
- To compare parent training outcomes against treatment as usual in a randomized controlled trial setting.
Main Methods:
- A multicenter, 2-arm, parallel-group randomized controlled trial was conducted in Danish specialist ADHD clinics.
- 164 children aged 3-7 years with ADHD received either parent training or treatment as usual.
- Outcomes, including parent-rated ADHD symptoms, were assessed at baseline, post-treatment, and at 36-week follow-up.
Main Results:
- Parent training significantly reduced parent-rated ADHD symptoms compared to usual care (p = .009, d = 0.30).
- Improvements in parenting self-efficacy and reduced family strain were observed.
- These positive effects persisted at the 36-week follow-up, but no effects were found on teacher ratings or direct observations.
Conclusions:
- Evidence-based parent training is valuable for preschool ADHD in routine clinical settings, particularly for parent-reported outcomes.
- The study highlights the importance of parent-reported outcomes in assessing intervention effectiveness.
- Unexpectedly, parent training did not show effects on child conduct problems in this trial.
Objective:
Parent training is recommended for attention-deficit/hyperactivity disorder (ADHD) in preschool children. Evidence-based interventions are important, but only if they produce better outcomes than usual care.
Method:
The authors conducted a multicenter, 2-arm, parallel-group, randomized controlled trial in routine specialist ADHD clinics in the Danish Child and Adolescent Mental Health Services. Children (N = 164, 3-7 years old) with ADHD received a well-established parent training program (New Forest Parenting Programme; n = 88) or treatment as usual (n = 76). The primary outcome was parent ratings of child ADHD symptoms. Secondary outcomes included teacher ratings and direct observations of ADHD symptoms. Outcomes were measured at baseline, after treatment, and at follow-up (36 weeks later). Representativeness of participants was evaluated against the total national cohort of children (N = 1,378, 3-7 years old) diagnosed with ADHD during the same period using the Danish Civil Registration System. Statistical analysis used a repeated measure model.
Results:
After treatment, the parent training program was superior to treatment as usual on parent-rated ADHD symptoms (p = .009; effect size d = 0.30) and on parenting self-efficacy and family strain. Effects persisted to 36 weeks after treatment. There were no effects on teacher ratings or direct observations of ADHD or on ratings of conduct problems or parenting. The clinical sample was similar to the national cohort of young children with ADHD.
Conclusion:
Evidence-based parent training has value as an intervention for preschool ADHD in routine clinical settings. As in previous trials, effects were restricted to parent-reported outcomes. Surprisingly, there were no effects on child conduct problems.

Parenting Styles
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
