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;...
Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
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.
Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Summary

Inattention, a core symptom of ADHD, strongly predicts school failure. Hyperactivity/impulsivity and oppositional defiant disorder symptoms do not significantly impact academic performance when inattention is considered.

Area of Science:

  • Child Psychology
  • Neurodevelopmental Disorders
  • Educational Psychology

Background:

  • Attention-deficit hyperactivity disorder (ADHD) is frequently linked to academic difficulties, with inattention (IN) being the primary suspected factor.
  • The role of oppositional-defiant disorder (ODD) in academic performance is less clear due to its high comorbidity with ADHD.

Purpose of the Study:

  • To investigate the independent contributions of inattention (IN), hyperactivity/impulsivity (H/I), and ODD to school failure.
  • To clarify the relationship between these ADHD-related symptoms and academic outcomes.

Main Methods:

  • SNAP-IV questionnaires were administered to parents and teachers of 241 sixth-grade students.
  • Statistical analyses were performed to assess the correlation between symptom scores (OP, H/I, IN) and school year failure.

Main Results:

  • Inattention (IN) demonstrated a significant positive correlation with school failure.
  • Hyperactivity/impulsivity (H/I) and oppositional defiant (OP) symptoms were not significantly associated with school failure after controlling for inattention.

Conclusions:

  • Oppositional defiant (OP) and hyperactivity/impulsivity (H/I) symptoms are not significant predictors of school failure when inattention is accounted for.
  • Inattention (IN) emerges as a robust, cross-culturally relevant predictor of school failure, underscoring its critical impact on academic success.
