CHILD PSYCHOPATHOLOGY


🔹 Chapter 1: What Is Child Psychopathology?

Definition

Psychological disorders = patterns of behavioral, emotional, cognitive, or physical symptoms associated with distress and impairment.

  • Diagnoses describe behaviors — not the child

  • Many problems exist on a continuum


🔹 Key Developmental Concepts

Multifinality

Same starting point → different outcomes
Example: Maltreatment → depression, conduct disorder, or normal functioning.

Equifinality

Different starting points → same outcome
Example: Conduct disorder from genetics OR environment.


🔹 Risk & Protection

ACEs (Adverse Childhood Experiences Study, 1995)

Early trauma strongly predicts:

  • Mental health problems

  • Substance abuse

  • Physical illness

  • Reduced life expectancy

Protective factors (Resilience):

  • Strong coping skills

  • Supportive family

  • Authoritative parenting

  • Caring adults outside family


🔹 Theoretical Perspectives

1. Biological

  • Brain development & neuroplasticity

  • Gene × environment interaction

2. Psychological

  • Behavior (ABC model)

  • Cognition

  • Emotion regulation

3. Social/Cultural

  • Family system

  • Community

  • Culture

  • Bronfenbrenner’s ecological model

👉 Best approach = multi-theoretical


🔹 Attachment Theory

Attachment forms 6–12 months.

Styles:

  • Secure

  • Avoidant

  • Resistant

  • Disorganized

Insecure attachment = ↑ risk for psychopathology.


🔹 Assessment & Diagnosis

Purposes:

  • Describe

  • Diagnose

  • Predict (prognosis)

  • Guide treatment

Tools:

  • Clinical interviews

  • Behavioral ABC assessment

  • Psychological testing (e.g., WISC)

  • CBCL

Classification:

  • Categorical (DSM)

  • Dimensional (continuum approach)

DSM Pros:

  • Shared language

  • Validation for families

DSM Cons:

  • Stigma

  • Oversimplifies complexity


📘 Chapter 5: Intellectual Disability (ID)

Definition

Deficits in:

  1. Intellectual functioning (IQ)

  2. Adaptive functioning

  3. Onset before age 18

Adaptive functioning = conceptual, social, practical skills


Severity Levels

  • Mild (85%)

  • Moderate (10%)

  • Severe (3–4%)

  • Profound (1–2%)

Global Developmental Delay = under age 5 when severity unclear.


Causes

Prenatal: genetic, maternal illness, poverty
Perinatal: prematurity, birth complications
Postnatal: TBI, malnutrition, abuse


Treatment

  • Early intervention is key

  • Enriched environments (e.g., Abecedarian Project)

  • Support adaptive skills


📘 Learning Disorders (SLD)

Specific Learning Disorder:

  • Reading

  • Writing

  • Math

Discrepancy between IQ and achievement.

Often associated with:

  • Anxiety

  • Depression


📘 ADHD

Definition: Persistent inattention and/or hyperactivity-impulsivity causing impairment.

Presentations:

  • Predominantly Inattentive

  • Predominantly Hyperactive-Impulsive

  • Combined

Criteria:

  • Before age 12

  • In multiple settings

  • Causes impairment

Treatment:

  • Stimulants

  • Parent training

  • School interventions

  • Combined approaches best


📘 Prosocial Lie-Telling Study (Williams et al., 2015)

Authors: Shanna Williams, Kelsey Moore, Angela M. Crossman, Victoria Talwar


Key Question

What predicts children’s ability to tell prosocial lies?


Key Concepts

Prosocial Lie

Lie told to benefit someone else (e.g., “I like the gift”).

Executive Function

  • Working memory (Digit Span)

  • Inhibitory control (Stroop)

Theory of Mind (ToM)

Understanding others’ mental states
Second-order false belief = “She thinks that he thinks…”


Findings

  • 59.5% told a prosocial lie

  • Executive function predicted lying

  • Second-order ToM predicted maintaining the lie

  • Age did NOT predict initial lie

  • Age DID predict semantic leakage control


Big Takeaway

Prosocial lying is linked to:

  • Working memory

  • Inhibitory control

  • Perspective-taking ability

It reflects social and cognitive development, not simply dishonesty.


🔥 Most Testable Themes Overall

  1. Multifinality & equifinality

  2. ACEs & resilience

  3. Attachment patterns

  4. DSM strengths & weaknesses

  5. ID = IQ + adaptive functioning

  6. ADHD presentations & treatments

  7. Executive function + ToM in prosocial lying
