Insights

Collaborative problem solving (CPS) effectively reduced oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Some children required stimulant medication for persistent ADHD symptoms.

Area of Science:

  • Child Psychology
  • Neurodevelopmental Disorders
  • Behavioral Therapy

Background:

  • Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) are common in children.
  • Effective interventions are needed to manage these complex conditions.

Purpose of the Study:

  • To evaluate the effectiveness of collaborative problem solving (CPS) for children aged 6-13 with ADHD and ODD.
  • To assess symptom reduction and overall improvement post-intervention and at follow-up.

Main Methods:

  • Seventeen families participated in 6-10 sessions of CPS training.
  • Primary outcomes included SNAP-IV (ADHD/ODD scores) and Clinical Global Impression-Improvement (CGI-I).
  • Secondary outcomes used the Conners' scale and Family Burden of Illness Module (FBIM).

Main Results:

  • Significant reductions in ODD, ADHD, Conners' total, and FBIM scores were observed post-intervention and at 6-month follow-up.
  • A subgroup showed limited improvement in hyperactivity/impulsivity without stimulant medication.
  • 53% of participants showed much improved or very much improved CGI-I scores post-intervention, rising to 81% at follow-up.

Conclusions:

  • Collaborative problem solving (CPS) is a viable intervention for reducing ODD, ADHD, and emotional lability symptoms.
  • Adjunctive stimulant medication may be necessary for some children with ADHD to achieve symptom remission.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Coping Strategies: Problem Focused01:27

Coping Strategies: Problem Focused

Coping strategies are methods people use to manage, tolerate, or reduce the effects of stressors. These strategies involve both behavioral and psychological actions to handle stressful situations. One common approach is problem-focused coping, which aims to change or eliminate the source of stress rather than merely addressing its consequences. This method involves taking direct action to resolve the issue causing stress.
For example, consider a student who struggles to understand their...
Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
Problem-Solving01:29

Problem-Solving

Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:
