Insights

The 60-month Ages and Stages Questionnaire (ASQ) is not a reliable tool for predicting low intelligence quotient scores in very preterm children at age six. Further research is needed for cost-effective developmental screening.

Area of Science:

  • Neonatal research
  • Developmental pediatrics
  • Psychometrics

Background:

  • Children born very preterm are at increased risk for developmental delays, including lower intelligence quotient (IQ).
  • Effective developmental screening tools are crucial for early intervention but must be cost-effective for follow-up programs.
  • The Ages and Stages Questionnaire (ASQ) is a widely used developmental screening tool.

Purpose of the Study:

  • To evaluate the accuracy of the 60-month ASQ in predicting a low IQ score at age six years in children born very preterm.
  • To determine if the ASQ can serve as a valid and cost-effective screening tool in this population.

Main Methods:

  • A prospective follow-up study included 54 very preterm children.
  • Children underwent an IQ test at six years of age.
  • The 60-month ASQ was administered at 4.5 or 5 years, with receiver operating characteristic (ROC) curve analysis used to find the optimal cut-off score.

Main Results:

  • At 4.5 years, an ASQ cut-off score of 242 predicted low IQ with 67% sensitivity and 59% specificity.
  • Analysis at 5 years was limited due to only one child having a low IQ score.

Conclusions:

  • The 60-month ASQ did not demonstrate sufficient accuracy to be recommended as a screening tool for predicting low IQ at age six in very preterm children.
  • The findings suggest the ASQ may not be a suitable cost-effective assessment for this specific high-risk group.

Biological Influences on Intelligence01:30

Biological Influences on Intelligence

Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

z Scores and Area Under the Curve01:17

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Measures of Intelligence01:29

Measures of Intelligence

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
