Self-Report Tests of Personality01:22

Self-Report Tests of Personality

262
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Wechsler's Contribution to Measures of Intelligence

1.3K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

Measures of Intelligence01:29

Measures of Intelligence

4.7K
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;...

Summary

A new computerized adaptive test (CAT) using multidimensional item response theory (MIRT) offers a rapid and precise method for assessing cognitive function in older adults. This tool shows promise in identifying mild cognitive impairment (MCI) and Alzheimer's disease (AD) risks.

Area of Science:

  • Neuroscience
  • Psychometrics
  • Gerontology

Background:

  • Mild cognitive impairment (MCI) affects up to 20% of older adults, with a significant risk of progressing to Alzheimer's disease (AD).
  • Traditional cognitive assessments are time-consuming and require specialized administration.
  • Aging-related cognitive decline can begin decades before noticeable impairment.

Purpose of the Study:

  • To develop and validate the first computerized adaptive test (CAT) based on multidimensional item response theory (MIRT) for assessing global cognitive function.
  • To create a rapid, precise, and repeatable cognitive assessment tool for adults.
  • To present results for a prototype CAT (pCAT-COG).

Main Methods:

  • Developed a prototype CAT (pCAT-COG) using a multidimensional item response theory (MIRT) framework.
  • Sampled items across five cognitive domains: episodic memory, semantic memory/language, working memory, executive function, and processing speed.
  • Calibrated a 57-item bank using a bifactor MIRT model and validated pCAT-COG scores against standard neuropsychological assessments.

Main Results:

  • The bifactor MIRT model demonstrated superior fit compared to unidimensional models.
  • pCAT-COG scores showed a significant inverse correlation with age (r = -0.44).
  • Simulated adaptive testing with 11 items closely correlated with full-bank scores (r = 0.94), distinguishing between MCI and no cognitive impairment (NCI) with a large effect size (1.08 SD).

Conclusions:

  • Multidimensional item response theory (MIRT)-based CAT is a feasible and valid approach for assessing global cognitive impairment.
  • This work establishes a foundation for a comprehensive CAT-COG with broader measures.
  • The developed tool is comparable to lengthy in-person assessments and suitable for widespread use.
