5B Assessment of Infant and Preschool Abilities
2
Infants vs. Preschool

• Infants birth to 2 ½
• Preschool 2 ½ to 6
• Infant tests load on sensory and motor
  development
• Standard measures EX. Stanford Binet are used
  with preschool and load on cognitive skills and
  spatial thinking

Infant Assessment
4
Gesell Developmental Schedules

• Purely observational
• Age range birth to 6 months
• Item p. 159
• Used mainly by pediatricians
• Development of infants is time bracketed
• Use of screening of at risk infants

5
Neonatal Behavioral Assessment Scale (NBAS)

• Emphasis is the need to document the
  contributions of the newborn to the parent-infant
  system
• Administered in the first week of life
• Items p. 160
• Provide feedback to parents

6
Ordinal Scales of Psychological Development (OSPD)

• Ages 2 weeks to 2 years
• 6 scales each has 5-15 ordinal steps
• Sound index of sensory motor intelligence
• Dont use for predictions

7
Bayley Scales of Infant Development-II

• Mental scale and motor scale
• Mean 100, SD 16
• Age 1 to 42 months

8
Mental Scale Gregory 2004 p. 162

• Sensory perceptual acuities
• Acquisition of object memory
• Memory, learning, and problem solving
• Vocalization, verbal communication
• Early evidence of abstract thinking
• Habituation
• Mental mapping
• Complex language
• Mathematical concept formation

9
Motor Scale Gregory 2004 p. 162

• Degree of bodily control
• coordination of large muscles
• Fine motor control
• Dynamic movement
• Dynamic praxis
• Postural imitation
• Stereogenosis

10
Bayley Scales of Infant Development-II

• Bayley Scales of Infant Development-II is the
  best in the field
• Takes skill and time to administer

11
Preschool Assessment
12
Assessment of Preschool Intelligence Gregory 2004
p. 164

• Wechsler Preschool and Primary Scale of
  Intelligence (WPPSI-R)
• Stanford-Binet 4 (SBFE)
• Kaufman Assessment Battery for Children (K-ABC)
• McCarthy Scales of Childrens Abilities (MSCA)

13
Wechsler Preschool and Primary Scale of
Intelligence (WPPSI-R)

• Ages 3 to 7 years 3 months
• An excellent long term predictor of intelligence
  and adolescent school performance
• Good for the DX of mental deficiency in preschool
  and early school children

14
Stanford-Binet 4 (SBFE)

• Age 2 through adult
• Sattler advised reporting two scores verbal
  comprehension and non-verbal reasoning/visualizati
  on
• Items p. 166

15
Kaufman Assessment Battery for Children (K-ABC)

• Oriented toward psychoeducational assessment and
  educational planning
• Ages 2.5 12.5
• Figure 5.5 p. 167
• 5.7 p. 168

16
McCarthy Scales of Childrens Abilities (MSCA)

• Note norms are badly outdated
• Scales p. 171

17
Practical utility of infant and preschool
assessment

• Little or no correlation between performance
  during first 6 months and IQ after age 5
• Correlation between preschool tests and later IQ
  is typically strong, significant, and meaningful
• IQ reasonably stable by 8 years of age

18
Practical utility of infant and preschool
assessment (2)

• Important use of infant tests is screening for
  developmental disabilities
• Very low, -2 SD scores on the Bayley mental scale
  may predict mental retardation later in life
