   – Acquired: CNS injury, chronic disease
   – Temperament
• Parents
   – Psychopathology
   – Parenting skills
   – Relationship between parents

          Assessment of kids
• Note symptoms as multi-determined rather than
  due to one diagnosis
• Drawing: include self, family, house*
• Assess with family
• More emphasis on social/psychological treatment
• Differences in medication use
• Much less admission
• Role of school
• Child protection issues
• Growth: incremental increase of a characteristic
• Maturation: phases of development that are
  mainly due to innate or endogenous factors
• Development: changes in behaviour and structure
  that can be systematically related to age
• Freud: emotional
• Piaget: cognitive
• Erikson: social
Gist                  Cognitive & development
                      Piaget development is the result of the
                 interaction between the individual and the
               Neurological maturation
               Exposure to experience, applying more

               complex reasoning, practising new skills

Sensori-         Piaget‟s stages
              Reflexes e.g. feeding dominate
              Self & non-self recognitions
              Object permanence
Pre-          Egocentric thinking: can‟t imagine others have a point of view
operational   Animistic thinking*
              Problems with conservation: vol, no., mass, time

• Levinson: Novice phase (sorting through
  possibilities in love and work)
• Erikson: psychosocial moratorium (free role
  experimentation) Identity vs. Role confusion
• Parsons: “the roleless role”
• Piaget: growth in hypothetico-deductive reasoning

• Insomnia
    – So don‟t give late
•   Depression/dysphoria
•   Worsening of tics

• Some families find certain foods make it
• So avoid those foods, if no nutritional

      • Many had medication

• Medication/combined better than other two
• Psychosocial intervention (no medication) similar
  outcome to community-based
• Little difference between medication alone and
   – Lower doses of medication if combined
   – On some secondary measures, combined but not
     medication alone superior to other two treatments

  Child & adolescent

Behaviour disorders
     Disruptive behaviour disorders
        DSM: > or < 10
        Mild. Moderate or severe


5-10% Of 8 to 16yr olds
Boys > girls 3:1
Towards adolescence gender difference lessens ++ esp. for ODD
          Aetiology of DBD
1. Family environment and rearing:

• lack of clear rules
• poor supervision,
• harsh and esp. inconsistent discipline
• violence towards or in front of the child
• Marital disharmony
• Large family size
NB Parental mental illness or D&A abuse
             Aetiology of DBD
2. Biopsychological factors

•   high impulsivity,
•   active/difficult temp. & bad fit with parenting style
•   CNS 5-HT
•   cognitive difficulties e.g. low IQ leading to impaired
    school performance
•   genetic inheritance
•   autonomic hypoarousal/arousability
           Aetiology of DBD
3. Social factors

 peer delinquency
 gang membership
 urban residence, esp. in high crime
 large family size
 poverty
 Disruptive Behaviour Disorders
• Conduct disorder is persistent violation of
  socially-defined rules
• Oppositional defiant disorder is milder
• Delinquency refers to law breaking
  – may be part of peer activity
• Hyperactivity
• Depression
   – In minority (Qu 45)
• Psychiatric disorders more likely in girls than boys
• Educational failure
• Poor interpersonal relations
   – ICD-10 has socialised and non-socialised CD,
     depending on presence of normal peer relations
• Environmental factors more important
  – high concordance in MZ and DZ twins
• Associated with maternal smoking in
  – stronger for males, persistent CD, violent CD
• Monoamine abnormalities
• Heritability of 0.4 for CD
Heritability of Behaviour Disorders
• Heritability: the contribution of genetic differences to
  observed differences among individuals for a particular
  trait in a particular population at a particular time
• About 0.4 for conduct disorder (0.7 for ADHD)
• Greater heritability for early onset and persistent behaviour
• Latent class analysis suggests strong genetic influence for
  ADHD/conduct disorder symptoms but almost no genetic
  influence for „pure‟ CD Sx
Juvenile Delinquency
•   90% against property
•   Peak in law-breaking in late teens
•   Peak in violence in early 20s
•   ½ to ¾ of convicted don‟t repeat
Assoicated   Learning disorders
             Mood/anxiety disorders
             Low self-esteem
Course &     •Direct: 20-30% CD  ASPD
             •Common cause: biological predisposition or
links with   environmental deprivation leading to later adult
adult        personality disorder

         Treatment of DBD
• Education and liaison with referring school:
  teacher training, school-based intervention
• Individual therapy

  - Can be taught how to initiate conversations, respond to
  others, refuse requests, and make requests of others
  - “Wilderness School” programs
  - Treatment Foster Care

    Parent management training
• Behaviour diary: ABC (Antecedents, Behaviour,
• Positive reinforcement training. Taught to reward
  prosocial behaviour with praise, star charts, treats
• Moderated negative consequences. Restriction of
  privileges or time-out
• Monitoring & supervision.
• Problem-solving/negotiation strategies.
 Other parent training programs
• Parent Child Interaction Training PCIT
• Training parents to give appropriate
• Group discussion videotape modelling

• Family therapy
         Techniques taught in PT*
•   Overcorrection
•   Time out
•   Extinction
•   Differential reinforcement
•   Punishment
     • follow the child‟s behaviour,
     • be delivered immediately after the child‟s behavior,
     • hurt enough to be significant to the child,
     • be consistently applied, and
     • have verbal clarification
     Techniques taught in PT

Reinforcing positive behaviour:

Vigilance for prosocial behaviour, flexibility and
doing the right thing so that…

Verbal recognition
Reward such as treats
Reward systems such as star charts

eating disorders
                Feeding disorder
A. Feeding disturbance as manifested by persistent failure
to eat adequately with significant failure to gain weight or
significant loss of weight over at least 1 month.
B. The disturbance is not due to an associated
gastrointestinal or other general medical condition (e.g.,
esophageal reflux).
C. The disturbance is not better accounted for by another
mental disorder (e.g., Rumination Disorder) or by lack of
available food.
D. The onset is before age 6 years.
A. Persistent eating of nonnutritive substances for a
period of at least 1 month.
B. The eating of nonnutritive substances is inappropriate
to the developmental level.
C. The eating behavior is not part of a culturally
sanctioned practice.
D. If the eating behavior occurs exclusively during the
course of another mental disorder (e.g., Mental
Retardation, Pervasive Developmental Disorder,
Schizophrenia), it is sufficiently severe to warrant
independent clinical attention.
             Rumination disorder
A. Repeated regurgitation and rechewing of food for a
period of at least 1 month following a period of normal
B. The behavior is not due to an associated
gastrointestinal or other general medical condition (e.g.,
esophageal reflux).
C. The behavior does not occur exclusively during the
course of Anorexia Nervosa or Bulimia Nervosa. If the
symptoms occur exclusively during the course of Mental
Retardation or a Pervasive Developmental Disorder,
they are sufficiently severe to warrant independent
clinical attention.
Child & adolescent disorders

A. Repeated voiding of urine into bed or clothes (whether
involuntary or intentional).
B. The behavior is clinically significant as manifested by

consecutive months or the presence of clinically significant
distress or impairment in social, academic (occupational),
or other important areas of functioning.
C. Chronological age is at least 5 years (or equivalent
developmental level).
D. The behavior is not due exclusively to the direct
physiological effect of a substance (e.g., a diuretic) or a
general medical condition (e.g., diabetes, spina bifida, a
seizure disorder).

      Reactive attachment disorder
A. Markedly disturbed and developmentally inappropriate
social relatedness in most contexts, beginning before age 5
years, as evidenced by either (1) or (2):
   (1) persistent failure to initiate or respond in a
   developmentally appropriate fashion to most social
   interactions, as manifest by excessively inhibited,
   hypervigilant, or highly ambivalent and contradictory
   responses (e.g., the child may respond to caregivers with
   a mixture of approach, avoidance, and resistance to
   comforting, or may exhibit frozen watchfulness)
   (2) diffuse attachments as manifest by indiscriminate
   sociability with marked inability to exhibit appropriate
   selective attachments (e.g., excessive familiarity with
   relative strangers or lack of selectivity in choice of
   attachment figures)
       Reactive attachment disorder
B. The disturbance in Criterion A is not accounted for solely
by developmental delay (as in Mental Retardation) and does
not meet criteria for a Pervasive Developmental Disorder.
C. Pathogenic care as evidenced by at least one of the
    (1) persistent disregard of the child's basic emotional
    needs for comfort, stimulation, and affection
    (2) persistent disregard of the child's basic physical
    (3) repeated changes of primary caregiver that prevent
    formation of stable attachments (e.g., frequent changes
    in foster care)
D. There is a presumption that the care in Criterion C is
responsible for the disturbed behavior in Criterion A (e.g.,
the disturbances in Criterion A began following the
pathogenic care in Criterion C).*
A. Repetitive, seemingly driven, and nonfunctional motor behavior (e.g.,
     Disorder of stereotyped movement*
hand shaking or waving, body rocking, head banging, mouthing of
objects, self-biting, picking at skin or bodily orifices, hitting own body).
B. The behavior markedly interferes with normal activities or results in
self-inflicted bodily injury that requires medical treatment (or would
result in an injury if preventive measures were not used).
C. If Mental Retardation is present, the stereotypic or self-injurious
behavior is of sufficient severity to become a focus of treatment.
D. The behavior is not better accounted for by a compulsion (as in
Obsessive-Compulsive Disorder), a tic (as in Tic Disorder), a stereotypy
that is part of a Pervasive Developmental Disorder, or hair pulling (as in
E. The behavior is not due to the direct physiological effects of a
substance or a general medical condition.
F. The behavior persists for 4 weeks or longer.

               Sudden, rapid, repetitive,         Simple

               stereotyped, non-rhythmic, which         Motor: eye blinking, abnormal tensing
               arise often with a premonitory           Vocal: throat clearing, grunting, snorting, chirping
               urge and relieve a sense of        Complex
               tension.                                 Motor: jumping, squatting, echopraxia
