Development and validation of a short form for the Raven's Coloured Progressive Matrices using a machine learning...

Area of Science:

• Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Raven's Coloured Progressive Matrices (CPM) is crucial for assessing general cognitive ability in children.
• The full 36-item CPM presents administration challenges in large-scale studies with young children due to time constraints.
• Developing a shorter, psychometrically sound version is essential for research efficiency.

Purpose of the Study:

• To develop and validate a short form of Raven's Coloured Progressive Matrices (CPM) suitable for preschoolers.
• To assess the psychometric properties of the new short form, including reliability and validity.
• To provide a more practical tool for measuring cognitive ability in young children within research settings.

Main Methods:

• A 12-item CPM short form was developed using penalised regression on a sample of 336 preschoolers (mean age 5.8 years).
• Statistical analyses were conducted to evaluate item stability, content validity, and concurrent validity.
• The short form's correlation with the full 36-item CPM was assessed.

Main Results:

• The 12-item CPM short form showed a very strong correlation (r=.94) with the full 36-item CPM.
• The short form demonstrated good item stability, content validity, and concurrent validity.
• The developed short form proved to be a reliable and valid measure of general cognitive ability.

Conclusions:

• The 12-item CPM short form is a psychometrically sound and practical alternative to the full version for assessing cognitive ability in preschoolers.
• This short form enhances research efficiency and practicality in developmental and educational studies.
• The validated CPM short form supports its use in large-scale research involving young children.
