What is the Guttman Scale Assessment?

The Guttman Scale Assessment is a cumulative scaling tool designed to evaluate hierarchical item responses and measure unidimensional constructs. It follows the principle that if a person endorses a more difficult item, they should also endorse all easier items that precede it in the hierarchy.

Who developed it and when?

The Guttman scale was developed by Louis Guttman in the 1940s as a method for measuring attitudes and other psychological constructs with high reliability and validity.

What type of assessment is it?

The GSA is a self-report assessment tool that uses cumulative scaling principles to measure psychological constructs in a hierarchical manner.

What does it assess?

• Hierarchical endorsement patterns
• Cumulative response tendencies
• Unidimensional construct measurement
• Scalogram analysis capabilities
• Attitude strength and consistency
• Response pattern reliability

How many items and what format?

10 items arranged in hierarchical difficulty, rated as "Yes" or "No" responses following cumulative scaling principles.

How is it scored?

The GSA uses scalogram analysis where responses are scored based on the cumulative pattern. Higher scores indicate endorsement of more difficult items, suggesting stronger manifestation of the measured construct.
