Insights
Cognitive behavioral parent training (CBPT) significantly improved behavior problems in children with Hyperkinetic Disorder/Attention-DeficitHyperactivity Disorder (HKD/ADHD) across various family situations compared to treatment-as-usual. Individual training showed slightly better results than group training.
Area of Science:
- Child and Adolescent Psychiatry
- Behavioral Psychology
- Clinical Psychology
Background:
- Behavioral problems in children with Hyperkinetic Disorder/Attention-DeficitHyperactivity Disorder (HKD/ADHD) exhibit significant variability across different family contexts.
- Understanding this variability is crucial for developing effective interventions.
Purpose of the Study:
- To assess the variability of HKD/ADHD behavior problems across family situations.
- To determine the extent to which Cognitive Behavioral Parent Training (CBPT) can modify these behaviors.
- To compare the effectiveness of individual versus group CBPT formats and their impact on a wider range of situations.
Main Methods:
- A multicentre randomized controlled trial involving 237 children diagnosed with HKD/ADHD.
- Comparison of individual and group CBPT against treatment-as-usual (TAU).
- Utilized the German version of the Home Situations Questionnaire (HSQ) to assess behavior problems across situations, with follow-up at 6 months, controlling for medication status.
Main Results:
- Parents reported substantial variation in the severity of behavior problems depending on the family situation.
- Both individual and group CBPT demonstrated significant improvements in behavior across numerous family situations compared to TAU.
- Individual CBPT showed a slightly greater positive impact than group CBPT in specific situations, both post-treatment and at 6-month follow-up.
Conclusions:
- CBPT offers a valuable addition to TAU for managing HKD/ADHD behavior problems, with small to moderate effect sizes.
- Individual CBPT was marginally more effective than group CBPT, which did not generalize to a wider range of situations.
- Situation-specific assessment using tools like the HSQ provides a nuanced understanding of child behavior and treatment outcomes, suggesting avenues for further research and development.
Objectives:
Assess (a) the variability of behaviour problems in children with Hyperkinetic Disorder/Attention-DeficitHyperactivity Disorder (HKD/ADHD) across a range of family situations and (b) the degree to which behaviour in each situation can be modified through a cognitive behavioural parent training (CBPT). Furthermore (c), compare the effectiveness of training in two different formats and (d) test the proposition that group treatment benefits behaviour in a wider range of situations than individual treatment.
Method:
A registered multicentre randomized controlled trial comparing individual and group parent training to treatment-as-usual (TAU) for N = 237 children with HKD/ADHD. A German version of the Home Situations Questionnaire (HSQ) was employed to examine behaviour problems across a range of family situations, treatment-related changes post-treatment and at 6-month follow-up, while controlling for medication status.
Results:
Parents reported considerable variance in severity of behaviour problems across situations. All groups improved with time, but individual and group CBPT led to significantly greater improvement than TAU in many family situations. Results present situation-specific treatment trajectories and demonstrate somewhat greater impact of individual compared with group training in certain situations post-training and 6 months later.
Conclusions:
CBPT clearly adds to TAU (with effect sizes in the small to moderate range depending on situation). Individual was somewhat more successful than group format (which did not succeed in a wider range of situations). HSQ situations reveal a differentiated picture of child behaviour and treatment results. Situation-specific assessment with an instrument like the HSQ offers promising perspectives that invite further development.
