Defining Childhood Psychopathology Definitions of “normal” depend on age Classification of many childhood disorders rests on our knowledge of normal childhood behavior
Childhood Disorders Externalizing Disorders problems in conforming to expected norms; often causes problems for others Internalizing Disorders experience of subjective distress; others often unaware of their difficulties

Diagnosing Internalizing Disorders: Depression and Anxiety Children can be diagnosed with “adult” anxiety disorders (e.g., MDD, OCD, GAD) Specific symptoms may differ from adults Some symptoms may be absent due to children’s developmental differences Difficulty in obtaining reliable information due to problems with self-reports
General symptoms Excessive distress associated with separation Worry for separation and/or harm to attachment figure School refusal Nightmares & complaints of physical symptoms Onset: before 18 years old Duration: at least 4 weeks Impairment Separation Anxiety Disorder
SAD is the most common anxiety disorder of childhood occurring in about 6% to 12% of all children Equally common in boys and girls About 80% to 90% of all children with SAD have another disorder (e.g., GAD, depression) Children showing school refusal due to SAD tend to be younger, female, of lower SES, and from single parent families.

Externalizing Disorders: Key Features rule violations negativity, anger & aggression impulsivity hyperactivity deficits in attention
Diagnosing Externalizing Disorders DSM-IV-TR divides externalizing disorders in to three major subtypes: Attention deficit/hyperactivity disorder (ADHD) Oppositional defiant disorder (ODD) Conduct disorder (CD)
ADHD Diagnostic Criteria Key features: hyperactivity, attention deficit and impulsivity symptoms begin before age 7 6 of 9 DSM-IV symptoms for 6 months symptoms visible across settings Three subtypes Predominantly Inattentive Type Predominantly Hyperactive-Impulsive Type Combined Type
ODD Diagnostic Criteria A pattern of negativistic, hostile and defiant behavior e.g. loses temper, argues with adults, defies or refuses to comply with adults’ requests Behavior causes significant impairment Impairment last for at least 6 months
CD Diagnostic Criteria Persistent and repetitive pattern of rule violations/social norms aggression to people, animals destruction of property deceitfulness or theft serious rule violation About 50% exhibit anti- social behavior into adulthood
Epidemiology: ADHD Problems may appear before age 3 Prevalence: approximately 5% of school-age children 50-60% of children in special education Some children continue to have ADHD as adults The symptoms interfere with daily functioning in different ways over life
Epidemiology: ODD & CD Prevalence rates ODD about 5-7% Conduct Disorder about 2-4% Higher in boys than girls
Etiology: Biological Factors Behavior Genetics Recent study of 4000 Australian found 80% concordance for MZ twins, 40% for DZ twins in ADHD, suggesting a strong genetic component. Neuropsychological Abnormalities Food Additives and Sugar No evidence Temperament
Etiology: Biological Factors Temperament Easy quickly form social relationships and follow discipline Difficult challenge parental authority Slow-to-warm-up shy & withdrawn
Etiology: Social Factors Peers, Neighborhoods, Television Parenting styles Coercion
Etiology: Social Factors Parenting Styles
Etiology: Social Factors Coercion Child wants a cookie Parent says “no” Child starts screaming Parent gives in, positively reinforcing child for throwing tantrum Child stops screaming- Negatively reinforcing parent for giving in behavior is reinforced
Etiology: Psychological Factors Attachment Theory Secure attachments facilitate both closeness and exploration Insecure (may be anxious, avoidant, or disorganized) attachments predict later internalizing and externalizing problems and social difficulties The “Strange Situation” Test Self-Control
Treatment ADHD: psychostimulants (e.g. Ritalin, Adderral) antidepressants selective norepinephrine reuptake inhibitor (e.g. Strattera) psychosocial treatment ODD: behavior family therapy
Treatment CD: Multisystemic Therapy residential programs diversion programs alternative to juvenile justice system

Childhood Disorders: Epidemiology Approximately 20% of children have a mental disorder Anxiety Disorders13% Mood Disorders6.2% Externalizing Disorders10.3% Suicide Gender differences Boys are more likely to be in treatment than girls Referral differences between children and adults
Childhood Disorders: Course & Outcome Prevalence rates of internalizing disorders increase with age Externalizing disorders often continue into adulthood, but antisocial behavior rarely begins during adult life better prognosis for later-onset CD better prognosis for ADHD if NOT comorbid w/ CD or ODD
Optional Slides
Etiological Factors Common to Most or All Childhood Disorders Difficult Temperament Insecure Attachment Ineffective Parenting Styles Emotion Dysregulation
Emotion Dysregulation Children fail to learn to recognize and control their emotions
Additional Etiological Factors Family risk factors Troubled peer relationships
Sociometric Ratings & Childhood Disorders Popular: many “liked most,” few “liked least” nominations Average: few “liked least” but not as many “liked most” as popular Rejected: many “liked least,” few “liked most” (opposite of popular) Neglected: few “liked least,” few “liked most” Controversial: many “liked least” and many “liked most”
Arbitrary Inference conclusions drawn in the absence of sufficient evidence or of any evidence at all Example A young girl approaches a playground and finds two children laughing. Before having a chance to say hello, the others walk away and look towards her direction. The young girl concludes that she is unattractive and that the other children were laughing at her. Cognitive Responses to Failure: Examples
Selective Magnification and Minimization exaggerations in evaluating performance Example 1 A young boy makes a couple of mistakes while trying out for a school play; he believes that he will never get the part for which he is auditioning (magnification). Example 2 The same boy gets the part that he is hoping to have in a school play; he believes that the teacher just made a mistake in choosing him (minimization). Cognitive Responses to Failure: Examples

Special Topic Childhood Depression
Myths about childhood depression Children can’t get depressed Childhood depression is rare Childhood depression is “just a phase”
Distressed infants show symptoms such as: lethargy eating and sleep problems irritability decreased attention & emotional expression Developmental Differences
Preschoolers may demonstrate: irritability and anger sad facial expressions and crying anhedonia somatic complaints, lethargy eating and sleep problems Developmental Differences
Middle Childhood (6-12) Unhappiness, decreased, socialization, sleep problems, irritability, lethargy. Beginning around age 9, aggression, self-reports of low self-esteem & helplessness, suicidal ideation Adolescence Similar to middle childhood, plus pessimism, feelings of worthlessness and apathy, comorbid substance abuse, eating disorders, antisocial behavior Developmental Differences
Intellectual functioning Interpersonal difficulties Areas of Impairment
Elementary school 2-4% of community sample, 8-15% of inpatients Adolescence 7% of community sample Gender Differences Pre-puberty, either no gender difference or slightly higher rates in boys By age 15, gender difference parallels that of adults: rates among girls are twice those among boys Epidemiology
Having a parent with a psychological disorder, especially a mood disorder, increases children’s risk of depression Genetic/Biological Vulnerability May be similar to the vulnerability for adult depression. Etiology: Familial & Biological Factors
Depressed kids have more distorted cognitions than non- depressed kids Learned Helplessness Model Depressed youth more likely to report: Higher “personal helplessness” and “universal helplessness” More internal, global, and stable attributional style for negative events. Etiology: Cognitive Factors
Vulnerabilities to Depression Failing to form stable, secure attachments with parents Abrupt separation of human and primate from mothers Etiology: Attachment
Kids from divorced or single-parent families are at an increased risk Hostile, tense, and punitive communication patterns within the family are more common among depressed youth Etiology: Home Environment
Difficult to use adult treatments with kids because they have limited memory, attentional, and verbal capabilities Because of kids’ involvement with family, family therapy may be crucial Treatment
Cognitive Restructuring Focuses on identifying and changing cognitions Role Playing Acting out interpersonal problems to improve kids’ abilities to find solutions Antidepressants No more effective than placebo Treatment (cont’d)
End of Special Topic
Fear & Anxiety in Children Children develop different fears for the first time at different ages; the onset may be sudden and may have no apparent environmental cause. Some fears are both common and relatively stable across different ages. Other fears become less frequent as children grow older.
Behavior Therapy Main technique for behavior therapy for anxiety disorders is exposure Cognitive Behavioral Therapy Teaches children to understand how their thinking contribute to their anxiety symptoms and how to modify their maladaptive thoughts Family Intervention Anxiety disorders often occur in family context Treatment of Childhood Anxiety Disorders
Distress expressed following separation from an attachment figure A normal developmental phase Children who fail to “outgrow” separation anxiety may be diagnosed with Separation Anxiety Disorder (SAD) Separation Anxiety
Age of Onset, Developmental Course & Outcome The earliest reported age of onset for SAD is 7 to 8 years, but children are often referred around 10 to 11 years SAD typically progresses from mild to severe avoidance SAD may be chronic or the onset may be sudden in a child who did not show any prior signs of a problem.
